xf86-video-geode: 800x480 and 1024x600 Panel support is broken

Hum....
As a "workaround", is it possible to use the 2.10.1-2 version geode driver in Ubuntu Karmic or Jaunty?
I tried to compile the driver from x.org, but it complains about xserver-xorg and xproto packages "not found".

I saw in https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-geode/+bug/234898 (i dont know how to use links) that q-funk made the geode-driver 2.11.4.1 avaliable for jaunty, intrepid and even for hardy, but can I (or you) made the 2.10.1-2 avaliable for Jaunty and Karmic? I know it's not the best solution, but it would be good for me as a workaround for my netbook until the bug is fixed upstream (jaunty is much faster in my netbook than intrepid, and Karmic is even more).

Thanks again.

Tried the new driver version (2.11.6-1), but it didnt help... I still cant get the 1024x600 to work.

Thanks.

Hi

I think I have the same issue running a Geode Graphics Card with a native display resolution of 800x480 on my Hercules ecafe ec-800 running Xubuntu 9.10 Karmic beta.
My Xorg.0.log outputs
(II) GEODE(0): RandR 1.2 enabled, ignore the following RandR disabled message.
(WW) GEODE(0): Option "PanelGeometry" is not used
(--) RandR disabled
Is it possible that there is a bug with the PanelGeometry option?

Thanks
Michae

If the driver says 'Option "PanelGeometry" is not used' it means that the hardware is not Geode GX but a Geode LX.

Geode LX has no "PanelGeometry" Option, it uses a "PanelMode" Option which has to be filled with the ModeLine specified earlier.

This at least applies to an Hercules eCafe EC-800 which I had to setup today. In this case the panel is only 800x480 and the Xserver stretches the output to 800x600 without manual fix.

I attach my working xorg.conf, it sets up an 800x480 display, the commented out parts contain lines which should work for 1200x600.

I'm using Karmic (xserver-xorg-video-geode 2.11.6-1).

Hi,

same problem here on a Hercules eCafe EC-800 with Xubuntu 9.10. I have tried Albrecht's xorg.conf but it failed. I have the GDM login screen with the correct resolution but XFCE doesn't want to start. I fall back to the login screen of GDM. After I have deleted the xorg.conf I can boot normally into XFCE.

This is my lspci:

Thanks a lot, Christian!!

Changing the PanelGeometry for PanelMode really worked for me.
I just need to make an adjustments, but worked really nice :)

Before mark this as fixed, I guess it would be a good idea to make these changes avaliable by default in next Ubuntu releases.

Thanks again, everybody!
Below, my new working xorg.conf for 1024x600 resolution in Karmic.

Rainer, how exactly are we supposed to change the defaults for the next Ubuntu release? What should be the new default mode?

Hi!

Honestly, I dont understand autoconfig scripts and those kind of things =)
(I dont know if it helps), but I manage to get the 1024x600 resolution in Karmic with this minimal xorg.conf. So i guess thats the xorg expected behavior to this specific hardware.

If you need more info, please let me know.

Thanks.

Hello,
I own an Hercules EC-800 and, tired of Mandriva, I'm trying to use Xubuntu distribution.
Every one I tried gives me the problem you are talking about, and I'd like to know if it's possible, with Xubuntu 9.10, to have both the resolutions working, I mean that I can choose between 800x480 and 1024x600.
I also didn't understand very well which one of the xorg.conf above I have to use maybe I have to try every one of them?
Thanks a lot
Davide

By the way, I don't have any /etc/X11/xorg.conf file in 9.10!!!
What am I supposed to do?
Thamks a lot again
Davide

Ok,
I created the needed file in /etc/X11/, stopped gdm giving
sudo service gdm stop
and restarted with
sudo service gdm start
but only 800x480 works: is there a definitive patch or something?

I used Albrecht's xorg.conf for Hercules eCafe EC-800 and Xorg 1.6.4

Thanks again

Davide

Hi,

I dont know how you used the Albrecht's xorg.conf, but if I understood it correctly, you might use a "modified" xorg.conf.
You need to uncomment some lines of his xorg.conf.

It would be something like the file I attached above.

Hope it works (I dont have an Hercules eCafe).

Thanks.

For that eCafe machine I had only the 800 x something resolution worked
(without this xorg.conf even that did not work).

But I had the eCafe from a colleague only for two days to fix its setup
... so I can't do experiments now.

Ok,
it works under gnome!
But for this small machine (only 512 MB of RAM and a 500 MHz AMD Geode), LXDE should be much better:
I tried to install LXDE+OpenBox, but only the 800x480 works!
I really can't undersatnd why, do you have any ideas?
Thanks a lot

Davide

the below workaround is posted elsewhere (in pieces), but may be useful for those experiencing this bug:
I finally came to use it for an old machine (otherwise working karmic perfectly of course) with an old D1751 17" AT&T monitor, after lots of research....

# use 'cvt' to get the modeline below to set for YOUR machine
# commands to set the screen to 1024 X 768 with xrandr, only on the machine required
xrandr --newmode "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
xrandr --addmode VGA1 1024x768_60.00
xrandr -s 2

# xrandr seems to work around the issue of the 'barebones' xorg.conf

Everything works in Xubuntu, but...
every time I have to login, i must start a xterm session, delete the file

$HOME/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml

type "exit" to switch back to graphical login screen and login again!

And then, the resolution is 800x480: if I change it to 1024x600, a displays.xml file is written again! And if I delete it, the problem still remains.

The bug affects lots of people (for exmple, see here: http://newyork.ubuntuforums.org/showthread.php?t=1309603 )

How can I get rid of this problem?

Thanks a lot!

I think the bug is described here, too https://bugs.launchpad.net/ubuntu/+source/xsplash/+bug/498164

Can you try to use the xf86-video-geode 2.11.8?

I have a Twinhead Twinmate e10 laptop which I have been struggling to get working with a 1024x600 screen in Ubunt or UNR. It always goes to 1024x768. I'd made it used to make it liveable by putting two blank panels at the bottom that "filled in" the excess 168 pixels. Then, working in full-screen mode it was the right size. Still not ideal though!

The most recent driver I was using was 2.11.8-4 (from a fresh install of Ubuntu 10.04)

But now I've got it working, thanks to Albrecht & Rainer, with the attached xorg file. I've also attached the lspci for my machine in case it's of interest!

Here's the xorg.conf for my machine (created in /etc/X11/xorg.conf as 10.04 doesn't have one by default)

Hi, phpmonkey & Rainer
    I have some question to ask you.
1). Why you use a 1024x600 screen? Is it 16:9 in your laptop. For the common dislay, both 4:3 and 16:9, after I use your xorg.conf to test the display (setup the AUTO menu), my xf86-video-geode version is 2.11.8, XServer version is 1.7.1. It also properly display (both 1024x600(16:9) and 1024x768(4:3)). So I confuse your question.

Why do you want to use them?

Is that what you want to do?

2).The attachment file is my xorg.conf. You can try to it in your environment. Please support the reproduce steps about bug. Could you support a picture to explain the phenomenon? I will follow it.

Thanks,
Hunk Cui

Hi Hunk.

1. yes, that's what I wanted to do. My old netbook had an 1024x600 (16:9) screen. I dont know if that was your only question.

2. I'm afraid I can't use your xorg.conf because I sold the netbook. So I can't help you. Maybe phpmonkey can.

Thanks.

Hi, Rainer

1. An 1024x600 (16:9) screen is properly diplay (through setup the VGA/LVDS AUTO menu), it can display the 16:9 and 4:3 screen, so I confuse whether it is a bug.
2. If everyone reproduce the bug phenomenon, please tell me the steps.

Thanks,
Hunk Cui,

Dear Hunk Cui,

Yes my computer has a 16:9 ratio (lspci already provided) which is why I was seeking a 1024x600 resolution.

I will provide the info I have, please let me know if I am missing anything.

I tested the three scenarios in the following order

1. no xorg.conf - default for 10.04
2. Hunk Cui's xorg.conf
3. "my" xorg.conf (provided earlier)

I will provide screenshots showing Monitor config & xorg.0.log

I will also attach my syslog (which spans the three cases).

Please let me know if I can do anything else (preferably with instructions!)

As you can see from the screenshots...

#1 doesn't have the option 1024x600 and defaults to 1024x768

#2 when I rebooted I got the following error message:

"Ubuntu is running in low-graphics mode.
The following error was encountered. You may need to update your configuration to solve this.
(EE) Failed to load module "extmod" (module does not exist, 0)
(EE) Failed to load module "dbe" (module does not exist, 0)
(EE) Failed to load module "glx" (module does not exist, 0)

(EE) Failed to load module "record" (module does not exist, 0)

Then I didn't have the option of 1024x600 and it defaulted to 800x600

#3 works fine

Hi, phpmonkey,

Please support your work fine xorg.conf file.
BTW: as usual, you can run "/usr/bin/Xorg -configure" to produce the system xorg.conf (in /root/xorg.conf.new), then replace the Driver name is "geode". then copy to "/etc/X11/" (rename xorg.conf), the system will find this file.

Hi, phpmonkey

You can setup 1024x600 screen, and run it for a long time. Then see whether it is working fine.

Thanks,

Hi Hunk Cui,

The xorg.conf file that works for me is attached to this earlier comment: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-geode/+bug/433142/comments/26

I'm fine with that conf file, but I'm happy to do more testing, so I tried to run "usr/bin/Xorg -configure" but I just get the error message:

"Fatal server error:

    If this server is no longer running, remove /tmp/.X0-lock
    and start again.

Wonderful! I can confirm that with 2.11.9-5 on my TwinHead Twinmate e10 I can now get the correct ratio.

However, It defaults to 640x480 (4:3), which I quickly changed to 1024x600 (16:9) ;) [These are now the only two options]

When I boot up, the login screen still displays skewy, with the 4:3 ratio (which doesn't happen when I have the xorg.conf file)

Cheers,

Jenny (phpmonkey)

Right, so we finally offer the right modes, but we default to the wrong one. This can probably be easily fixed.

I wonder what makes the display buggy during boot, though.

phpmonkey,
   I am glad that you can get the 1024x600 resolution for your panel without the modeline in xorg.conf.
   As you said, there are two issues remaining here:
   1) The remaining resolution options are reduced. Your remaining options turn to be two. And on my notebook, there are 3 options(1024x600, 640x480, 320x240) remaining.
   2)the login screen still displays skewy, with the 4:3 ratio. I have not met this issue. My default resolution after boot is 1024x600, when I change the resolution from 1024x600 to 640x480, everything is fine.
   My X server version is 1.7.99.901.
   Could you provide your Xorg.0.log for this experiment?

Thanks,
Frank

Hi Frank,

In reply to your comments,

1)

I have attached the Xorg.0.log in question.

I'm sorry, I didn't intend to submit that comment mid-draft (:

My xserver-xorg version is 1.7.5+5Ubuntu1

In reply to your comments,

1) Since the correct ratio for my screen is 16:9, I'm honestly not fussed about the availability of 4:3 ratios (640x480, 320x240, especially that last one given my screen size :))

2) This on the other hand is annoying. I've attached the Xorg.0.log

Cheers,
Jenny (phpmonkey)

Thanks for your reply. From your log file,
(**) GEODE(0): Default mode "640x480": 25.2 MHz (scaled from 0.0 MHz), 31.5 kHz, 59.9 Hz
(II) GEODE(0): Modeline "640x480"x59.9 25.18 640 656 752 800 480 490 492 525 -hsync -vsync (31.5 kHz)
(**) GEODE(0): Driver mode "1024x600": 49.0 MHz (scaled from 0.0 MHz), 37.3 kHz, 60.0 Hz
(II) GEODE(0): Modeline "1024x600"x60.0 48.96 1024 1064 1168 1312 600 601 604 622 -hsync -vsync (37.3 kHz)
We can see 1024x600 is the driver mode. That should be default:).
My patch is as follow:
+ {MODEPREFIX, 48960, 1024, 1064, 1168, 1312, 0, 600, 601, 604, 622, 0,
+ V_NHSYNC | V_NVSYNC, MODESUFFIX}
+ , /* 1024x600@60 */
Can you change the 48960 to 65000(or 81600) and give a try? I guess the clock rate is the reason why your skewy display. I am finding the reason now.

Thanks,
Frank

I upgraded my twinhead e10 to Maverick (clean install) and things worked beautifully "out of the box" (geode version installed by default is 2.11.9-5).

It booted up in 640x480 but after selecting 1024x600 (these are the only two options, fine by me!) and then "Make default" & "apply" it now boots up with the correct resolution every time. And there was much rejoicing!

Thanks everyone for your help, I really appreciate it.

Jenny (phpmonkey)

phpmonkey,
   You can use "cvt 1024 600 80" to generate the parameter, then write this command value to replace my patch below:
+ {MODEPREFIX, 48960, 1024, 1064, 1168, 1312, 0, 600, 601, 604, 622, 0,
+ V_NHSYNC | V_NVSYNC, MODESUFFIX}
+ , /* 1024x600@60 */
  Then you can get more modes to support. The above is the result of "cvt 1024 600 60". So some modes will be pruned by X server.

Thanks,
Frank

Jenny,
Where exactly did you select Make Default and Apply? Does this generate a custom xorg.conf with that resolution?

Martin,
The Make Default & Apply are buttons in "monitor preferences".
It doesn't seem to have created a custom xorg.conf file.
I have attached a screenshot.
Cheers,
Jenny

I have uploaded a slightly newer version of this driver to my PPA as a Lucid package.

The main difference now is that the 1024x600 resolution will only be available if the BIOS has the Panel output mode enabled. Also, the refresh rate was updated from 60Hz to 80Hz.

Can everyone please confirm whether this works as expected, when the resolution is selected via the monitor configuration tool shown above in Comment #86?

Currently having access to an eCafé EC800, I can confirm that 2.11.10-1 doesn't find 1024x600.

Please help check ret value in function LXGetLegacyPanelMode() in lx_panel.c.
If that ret value is 3, the patch I commit will not affect the resolution the panel supports.
If that ret value is 7, my patch will take effet.

Thanks,
Frank

Frank, can you please attach a small patch to this bug to implement printing the return value to the X log, so that others who may have problems with their panel may also check this? Thanks!

One item I'd like to point out in the above X log is that both Panel and VGA outputs are enabled by the BIOS. As such, adding support for this resolution only in lx_panel.c is likely to fail since it will not apply to the VGA output.

It should also be noted that the X log clearly reports that the display's refresh rate in 60Hz, which means that the new 80Hz refresh rate will not work.

Martin, the patch for printing the panel mode to X log has been committed to mail list. Please check. Actually in my previous patch, I have added note that explains why I use entry 7. I think you have seen that.
Yes, in the function LXGetLegacyPanelMode(), we firstly check if panel is supported. If that is supported, we will check which resolution we should use.
But actually, the entry 7 is not used and reserved in almost every geode board in BIOS setting. So unless you set it in BIOS to use entry 7(that is to say ret value is 7), that will forcelly use my 1024x600@80. Otherwise, the 1024x600@80 will not be used and will not affect your VGA resolutions. Please let the customer see the ret value with my patch. If that is not 7, the resolution failed thing is not caused by my patch. My patch is only for people who want use 1024x600 in panel mode.
Our geode platform certainly can support 80Hz refresh under some resolutions. The reason why the Xorg reports failure is because X server prunes some resolutions. That is not to say the geode can not support. Please understand that.

Thanks,
Frank

Here's the log on 2.11.10 with the patch added.

I figure out the reason from your log.
Please see the line in the log:
   (II) GEODE(0): VSA Panel Mode is: 800x600, pixel clock freq(kHz) is 40000
The platform ret value is 2. So entry 2 will be used(800x600@60). When this entry is used, most of the modes will be prunde by X server. And you will see only three modes are supported. It is because BIOS setting for the default mode error, not caused by driver!
It is very easy to give a quick fix. Set the ret value in LXGetLegacyPanelMode() to 7 manually in driver. Then 1024x600 will be supported and other resolution will appear(such as 1024x768).
i.e. in lx_panel.c
                   ...
                   */
                + ret = 7;
                   if (ret < 8) {...

Give a try and let me know the result.
If everything is fine. Change the BIOS to use correct entry.

Thanks,
Frank

Frank, the BIOS resolution is fixed and cannot be changed. There is no setting for it in the BIOS menu.

I sincerely doubt that the BIOS would be set to 800x600 since this laptop's display only supports 320x240, 640x480 and 1024x600. However, 800x600 happens to be our driver's default fall-back resolution, so this is probably what we're seeing.

Adding ret=7; does not fix it. It indeed makes several new modes appear but none of them is 1024x600. Anyhow, it doesn't fix the fact that this display only supports 60Hz refresh rates, while the settings for slot 7 is at 80Hz, either.

It also remains unclear to me what is the proper way to select that 1024x600@60 mode. I already know that DDC won't work since we're using a panel, so we must obviously select the resolution we want using an xorg.conf option. However, the xorg.conf variants attached to this bug report use different methods for configuring this and I need to know which one is the right one, so that I can document this in the README.

Martin,

Have you noticed that your Xorg_ec800_3.log still shows:
(II) GEODE(0): VSA Panel Mode is: 800x600, pixel clock freq(kHz) is 40000.
If you set ret=7, it should show as below:
(II) GEODE(0): VSA Panel Mode is: 1024x600, pixel clock freq(kHz)...

My 1024x600 entry is not used in your new test. Please make sure you use my entry 1024x600.

Thanks,
Frank

Frank, I have no idea why setting ret=7 in lx_panel.c did not produce any effect.

However, I'm concerned that this is turning into a big ugly hack that will require people to compile their own driver, simply because setting the desired mode is now completely dependent upon being able to change a setting in the BIOS, which is not always possible.

Martin,

   I think you have not successfully use entry 7. From your log, I see no clue entry 7 is used. If that entry is not used, why you get the conclusion that ugly hack result?
  On my malata platform(a geodeLX) notebook and another user's reply, there is no error at all using this mode(1024x600). Please believe that, this part I have given debug. And I know the process how the Xserver and driver exchange information.
  See my attached Xorg.0.log to see how my malata use entry 7. See my screen.png to see how 1024x600@80 is used.
  You can clearly see the entry 7 is used.

X log on Malata notebook(1024x600)

Screen after X window enters(1024x600)

As I said before, when the geode LX is designed, no wide screen panel appears on the market. So the HW registers does not include the support for that type panel. We use reversed entry 7 for people who want to use this special wide resolution. And our HW has the ability to support this 1024x600@80 resolution. The customer MUST do the customization before using that(like my patch shows). Using reserved entry does not affect users' previous settings.

Thanks,
Frank

Hello,
The bug affects also affects 10.10 Maverick Meerkat and 11.04.
Is there a way to fix it?
I tried every xorg.conf here, but none works!

If you want to support a new mode(i.e. 1024x600@60), add it to your code, and let that mode to be default.
See my reply on #75, #82, #84, #93, #95.

Thanks,
Frank

Basically, the short answer to laptop support with the Geode X driver seems to be that it needs a custom xorg.conf for each laptop, since it cannot probe the display for ideal size.

Upstream developers have now documented this fact and provided command examples for calculating display modes along with a sample xorg.conf that shows how the command's result can be used. This will be included in xf86-video-geode 2.11.13 to be released shortly.

Hi Martin, any news?
I have now 11.10 on my netbook ecafè ec-800 (12.04 won't install with this cpu...), bu it seems that xf86-video-geode 2.11.13 isn't available for Oneiric, is that true?

Thanks,

Davide

You can find it in my PPA. However, there won't be any official backport for releases older than Precise.

2.11.14 is available in my PPA. Can you test it and report whether it fixes the issue or not?

Hi,
sorry for the late answer.
I installed the 2.11.14 from your ppa, but I can't understand if I have to edit xorg.conf too or something else.
Maybe I've lost the thread, I can't remember the steps I have to do to make the 1024x600 resolution work... Can you make me a brief summary? Thanks a lot,

Davide

You still need the custom xorg.conf; that will never change. You can look at the README for sample content.

Hi martin,
800x480 and 1024x600 work perfectly with your 2.11.14 and the xorg.conf in the README file.
The other problems are that if i press Ctrl+Alt+F1 (or F2, F3, etc...) nothing happens, no cli, just a black screen. And also if I attach a tft monitor with the external vga port, I can't change the resolution and the internal monitor of the ecafe doesn't turn off.

Thaks a lot,

Davide

The issue you are experiencing when attaching an exernal display is normal.

Anyhow, this bug report was about making wide resolutions work on Geode-based laptops, which is now fixed, so I'm closing this report. :)
