Cannot scroll to bottom of system menu

Thank you for taking the time to report this bug and help make Ubuntu better. I'm unable to reproduce this bug in the latest development release. Could you please update, or use the latest livecd image to retest this and let us know if you are still able to reproduce the problem? If so, a screenshot might be useful to help understand what is going on. Thanks!

I can confirmed this bug. It`s present on my notebook (running Ubuntu 9.10 with all updates at this moment) .
Screenshot in attachment.

Marking confirmed based on the previous feedback. Any possibility this could depend on which language is being used? I'm still not able to reproduce it so far.

> Any possibility this could depend on which language is being used?\
No. I cange locale to en_us, bug still present.

I can`t speack C programming language, but it`s look like error in scroll box upper value calculation algorythm (launcher_iconview_set_category function from launcher-iconview.c file). I think, that author of first message said right.

If menu contains some like this (--- - group separator):
A B C D
E F G H
I J
---
K L M N
O P Q R
S T Y

row variable is 4, but must be 5. And I can`t found place with group separator height calculation.

Forgive me if I am wrong, but I newer wrote in C or similar language and smoke this sources only 5 minutes :)

Bug gone away for me.
I don`t know, how it happens exactly.

This happens to me too. It only happens when I am using a larger external screen, not with the netbook screen. Perhaps it only happens when there are five icons in each row. See screenshot.

I can also confirm this bug. Happens only with native widescreen resolution of my netbook. If I change the resolution to smaller than native 1280x800, then the scroll bar works as it should.

This error manifests itself if the total number of items in the last rows of each group is less then or equal to the number of columns

I confirm the bug on the eee box connected to a 1280x768 display. Using English. Screenshot attached

I can confirm this bug as well on a 1024x600 display (with nl_NL language). I have merely four icons per rows, and only one on the bottom row.

Scrolling back upwards with the arrow key seems weird as well, as sometimes the screen doesn't scroll upwards correctly. After arriving at the top row, I have to press the left and right arrows a few times before the top icons are fully visible (I cannot test this behaviour at the bottom row as I only see one icon in the bottom row). The category divider seems to cause issues sometimes when scrolling up using the arrow keys as well.

I can also confirm this bug.

I recently upgraded 2 laptops to 9.10. Everything went smooth, but there is an issue with the way the menu items are displayed on one of them. For example, I added a new menu item "Trunk" to the "Folders" menu, but the menu didn't expand. This resulted in the "Volumes" menu being written over top of my "Desktop" menu item.

Also, my Systems>Administration menu is not showing all of the menu items. The items are on the menu as I am sometimes able to find them with the pointer even though I can't see them. The are just below the viewable area, but I cannot scroll down any further. I suspect that the items have spilled out of the menu panel as my my "Desktop" folder did, but I'm only able to scroll down far enough to show last row of the panel. Removing menu items does not solve the problem.

I have removed and reinstalled the netbook remix packages without success.

This in on a 14" screen running 1280x800 resolution, NVIDIA GeForce 8400M GS card. I have tried activating both available drivers and there is no difference. If I use 1024x768, the menus work as they should. There seems to be an issue with 9.10 at 1280x800. 9.04 worked fine on this machine.

I can confirm this bug happened to me, but am reporting here because today, I've noticed the complete reversal of this bug.

Only recent updates I've had relating to netbook-launcher are:
libclutter-gtk (0.10-0 0.10.2-0ubuntu1 => 0.10-0_0.10.2-0ubuntu2)
libgnome-desktop (2.28.1-0ubuntu2 => 2.28.1-0ubuntu3)

Both were updated on 2009-11-11 @ 08:07:24

Attached is an image of what it now looks like for me.

I can't scroll to the bottom of the system menu using the arrow keys, but it works fine when I scroll using the touchpad's right edge to scroll.
Dell Mini 10v, 1024x600.

Hmm, perhaps I have a different issue, this is what I've found so far in the behaviour of the netbook-launcher iconview on a Samsung N110.

Res: 640x480
 2 Columns
 3 Rows per group of icons
 All icons showing. (Albeit, with a large gap after every third row)

Res: 800x600
 3 Columns
 3 Rows
 Only first 9 icons showing. (With a large gap on the bottom (3rd) row)

Res: 1024x600
 4 Columns
 3 Rows
 Only first 12 icons showing. (With a large gap on the bottom (4th) row)

This behaviour seems to coincide with these functions in nl-config.c

static gint
get_rows_for_height (gint height)
{
  gint rows = 3;

  if (height < 600)
    rows = 3;
  else if (height < 1025)
    rows = 4;
  else
    rows = 5;

  return rows;
}

static gint
get_cols_for_width (gint width)
{
  gint cols = 3;

  if (width < 801)
    cols = 3;
  else if (width < 1025)
    cols = 4;
  else
    cols = 5;

  return cols;
}

But altering them seems to make no difference?

Can anyone confirm?

Iain

Affected on both UNR and Ubuntu 9.10 desktop with netbook-launcher. Toshiba M750-S7202 tablet.

@Iain Bucław
I am experiencng the same bug on my eeepc 701.
With res of 800x480
omly 2 icons per colum and after 3th row (only in system tab!) a big gap.
after the gap all icons overlap eachother :o

and the overlap of icons

The gap isn't an patch, but image!
Don't know how i managed to enable the "patch-mode" (sorry, not native English ;) ), i can't edit the post.
So sorry...

I can confirm this bug too.
Lenovo S10 - 1024*600 (int) and 1280*1024 (ext)

Bug present in Ubuntu 10.04.

And in Files&Folders menu

I'm also seeing this with the mobile remix on an Acer Aspire Revo, with monitor at 1280x768 via VGA. Using English (UK). I have five icons per row (which seems to be important from earlier comments).

Because of this I can't see the icons for the Ubuntu software center, update manager, or users and groups, but I can just *click* on their border region.

I have the same issue on Dell Latitude E4200, 1280x800 resolution, 5 icons on a row. The last row in System->Administration is only partially visible (it has 5 icons too, so it does not even have to be the LAST row).

Also in Files&Folders, the Desktop icon is displayed below the Folders frame, which is only one row of icons high.

Same here on a Toshiba Satelite L300-11C 15" with a 1280x800px resolution and 5 icons on a row.

Also a weird problem in Files&Folders, the Desktop icon is displayed below the Folders frame, which is only one row of icons high.

Have this bug on the ASUS Eee 901

I have the same bug on my Acer Aspire One AO532h (both overlapping and scrolling). The resolution is 1280x720. This bug appears directly after installing of the system, Ubuntu 9.10 UNR. If I start netbook-launcher using 1024x768 resolution (using -w parameter, for example), all is fine.

netbook-launcher version is 2.1.12.

It seems, that this bug depends on width of the left menu. When Educational section was added, the bug disappeared (the menu became a little larger). My system language is Russian.

Can you please try with last lucid version, adding this ppa: https://launchpad.net/~ubuntu-desktop/+archive/ppa and then upgrading to get last clutk?

There is a proposed patch which should fix that.
Thanks for trying. I'm putting the bug report as Incomplete waiting for feedback.

This bug not fixed for me with last package clutk update (0.3.8.is.0.2.10-0ubuntu1). My system UNR 10.04 full updated on 22 Mar 2010 (beta 1), but problem with cannot scroll to bottom of system menu not resolved. My netbook Acer AO531h with 10' HD 1280x720 screen resolution and intel 945 GME graphics adapter. xdpyinfo reports: 1280x720 (338x190 mm) 96x96 dpi

ok, so the fix didn't work. Put the priority to high and reopening the bug.

There is a patch attached in the branch.

Today after update this bug was looking fixed for me (Acer Aspire One 531h, 1280x720). Thank you.

Your changes seems good, merged into trunk. Thanks a lot!
