I have a dual-cpu Sun W2100z workstation I really like. It’s getting rather old, but it’s pretty fast for things like programming and Internet use. Until the release of Ubuntu 9.04, the machne was running fine. After installing the new release it was pretty obvious that the X performance was terrible. Things like glxgears ran fine on this dual screen setup, but things like switching virtual desktops (I use the shortcut ctrl+alt+arrows a lot) took a few seconds when windows were maximized. Sadly, the free driver didn’t work with the 3300 x 1050 resolution I use.
After playing around with the millions switch and config options of the nvidia driver, I found a working setting:
nvidia-settings -a InitialPixmapPlacement=2
To enable this permanently, you can add it to System – Preferences – Startup Applications:
(put “nvidia-settings -a InitialPixmapPlacement=2” (without “”) in the command field).

EDIT: Workaround not longer needed as the drives has been fixed on the Ubuntu repositories.
Yeah. New Ubuntu release. Traditionally, this means upgrading without reading the release notes.
<Curse>. This is what it says (I read today):
nVidia “legacy” video support
The 71 and 96 series of proprietary nVidia drivers, as provided by the nvidia-glx-legacy and nvidia-glx packages in Ubuntu 8.04 LTS, are not compatible with the X.Org included in Ubuntu 8.10. Users with the nVidia TNT, TNT2, TNT Ultra, GeForce, GeForce2, GeForce3, and GeForce4 chipsets are affected and will be transitioned on upgrade to the free nv driver instead. This driver does not support 3D acceleration.
Users of other nVidia chipsets that are supported by the 173 or 177 driver series will be transitioned to the nvidia-glx-173 or nvidia-glx-177 package instead. However, unlike drivers 96 and 71, drivers 173 and 177 are only compatible with CPUs that support SSE (e.g. Intel Pentium III, AMD Athlon XP or higher). Systems with older CPUs will also be transitioned to the nv driver on upgrade.
The “nv” driver does not support my dual-monitor 2 x 1680×1050 resolution. After looking for some workarounds (compiling kernels) and at the point of a downgrade to 8.04, I found an easy solution.
