Bug: Ubuntu 8.10 and older nvidia video cards October 31, 2008

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.

EDIT May 27th 2008: FIXED how to make the changes permanent.
EDIT June 4th 2008: Don’t forget to install as well
linux-ubuntu-modules (in this case linux-ubuntu-modules-2.6.22-14-generic) when upgrading your kernel.
EDIT Oct 16th 2008: The restricted driver included in Ubuntu has been FIXED and the card works out of the box when enabling it through System-Administration-Hardware Drivers. Thanks, Ubuntu!

It’s probably a regression: on this laptop the broadcom wifi worked fine on the previous Ubuntu releases (although limited to 24mbit/s) and now I see the speed is stuck to an unacceptable 1mbit/s. I guess that’s the price you pay for hardware from companies that are not open source friendly. (more…)
