transparency not working with intel driver and LTSP

I also have the same issue on an intel laptop:

00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) [8086:2a02] (rev 0c)
00:02.1 Display controller [0380]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (secondary) [8086:2a03] (rev 0c)

FYI here is the lspci for the graphic on the other machine:

00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 09)
00:02.1 Display controller [0380]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a43] (rev 09)

work only with nomodeset
 description: VGA compatible controller
             product: Mobile 4 Series Chipset Integrated Graphics Controller
             vendor: Intel Corporation

nomodeset gets rid of the transparency problem, but my resolution falls back to 1024x768 when I do that. Is there a way around that or do I just need to configure X manually on these machines?

I did a git bisect on the intel driver to attempt to find where this was introduced. I ended up using pretty much the whole old intel driver as is that worked before and the problem was still present. My guess is that this isn't an intel driver specific issue and might have been introduced somewhere else in the X stack. Any suggestions at where I should look first? I'll probably try the mesa libraries next.

Sorry, I must have done something wrong before. Just did a forward port of the 2.12 driver and it works fine.

Thank you for the response.

What do you mean "2.12 driver"? Sinaptic did't find it.

@cyf221 I added it to the RLNX ppa: https://launchpad.net/~revolution-linux/+archive/xorg

I also tested the latest drivers under Oneiric and Unstable. It's better now, but not completely fixed. Many icons (notably the panel and menu icons) now have transparency. Some icons, like context-sensitive icons and also the title bar menu's icons are not transparent.

 Here is the debdiff that fixes the issue in natty

this is the fix for oneiric

These two debdiffs should be targeted to -proposed, otherwise they look good. Would still be great to have someone from the X team to have a quick look at them, then I'm happy to sponsor them if nobody else does.

Adding tasks for both natty and oneiric (debdiffs provided above) and also adding precise as it's the same version as oneiric and so is also affected by this bug.

The patch in the debdiffs here were NAKed by the intel maintainer, and he fixed it differently in the upstream driver. I have prepared oneiric and natty SRU packages with the fix but have to run tonight and will follow up on it in the morning as well as get it uploaded to precise and pushed to git.

The attachment "fix for natty" of this bug report has been identified as being a patch in the form of a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. In the event that this is in fact not a patch you can resolve this situation by removing the tag 'patch' from the bug report and editing the attachment so that it is not flagged as a patch. Additionally, if you are member of the ubuntu-sponsors please also unsubscribe the team from this bug report.

Hello Marc, or anyone else affected,

Accepted xserver-xorg-video-intel into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Just tested version 2:2.1.15.901-1ubuntu2.1 on oneiric and version 2:2.14.0-4ubuntu7.3 on natty.
Both are working as expected.

Thanks a lot for this upload.
