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. [1]: https://wiki.ubuntu.com/StableReleaseUpdates#Procedure Thank you for your understanding. ** Changed in: xserver-xorg-video-nouveau (Ubuntu) Status: Triaged => Fix Released -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/996168 Title: 10de:032c nouveau doesn't render items on lower third of desktop Status in “xserver-xorg-video-nouveau” package in Ubuntu: Fix Released Bug description: 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 --- ApportVersion: 2.12.7-0ubuntu6 Architecture: i386 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' DistUpgraded: Fresh install DistroCodename: trusty DistroRelease: Ubuntu 14.04 DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: NVIDIA Corporation NV34M [GeForce FX Go5300 / Go5350] [10de:032c] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Wistron Corp.
