10de:032c nouveau doesn't render items on lower third of desktop

[thom]

On the desktop, items that are moved down to below 1/3 of the screen disappear behind an "invisible horizon". It seems like although the desktop and backdrop are rendered nicely full screen, the items on it seem to be rendered to a smaller field and get clipped when passing the "border". Resizing the desktop to another size and back again seem to solve this issue.

WORKAROUND: NV34 (64MB) with laptop screen 1024x768, @60. Resizing and then resizing back again seems to be the only "fix" without disabling render acceleration.

WORKAROUND: Put the code below in a file, make it executable and put it in "startup applications" in your desktop:
#!/bin/bash
xrandr --output LVDS-1 --mode 800x600 --panning 800x600
xrandr --output LVDS-1 --mode 1024x768 --panning 1024x768

thom, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-nouveau REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.

Christopher, I installed the last developement release of Ubuntu (14.04) and it stalls after graphical login, leaving a blank screen so I only could try to fix stuff from the commandline.

I managed to get the apport report via commandline. I have my fingers crossed that the apport report did came through.

After that I did some tinkering and generated an Xorg.conf (Xorg -configure) and it mistakenly reported 4 videocards. After deleting the superfluous entries I could start the Graphical desktop but it is extremely slow (it takes several minutes to open a terminal which immediately locked up for several minutes) so it was quite difficult to test if the bug was still present.
At the moment the computer is working very very hard for several minutes now, trying to maximize a window. :-)
htop reports 100% CPU usage.
I guess that the whopping amount of 64MB VideoRAM is not really adequate for 14.04

I did manage to move a terminalwindow, however, just before it locked up. :-)

The reported bug seems indeed to be SOLVED in 14.04, thanks :-)

The downside is, of course, that 14.04 is not usable in it's present state on this rig.
I could do some further testing. I persume it would be more adequate to use Lubuntu then ?

thom, thank you for your comment. Regarding the severe performance regression going from 12.04 to 14.04, I would file a new report via a terminal so this could be bisected and dealt with separately via a terminal:
ubuntu-bug xorg

Regarding the original issue noted in the Bug Description, I am closing this report because as per your comment https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/996168/comments/23 the bug has been fixed in the latest development version of Ubuntu - Trusty Tahr.

This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please perform as much as possible of the SRU Procedure [1] to bring the need to a developer's attention.

Thank you for your understanding.
