Bug Description

Binary package hint: xserver-xorg-core

The xserver-xorg-core 1:1.0.2-0ubuntu10.5 update breaks Nvidia glx of NVIDIA Linux Display Driver - x86 (NVIDIA-Linux-x86-1.0-9629).
This is due to the fact that the deb installation procedure doesn't check if
/usr/lib/xorg/modules/extensions/libglx.so is a link to a third party
glx library as:
/usr/lib/xorg/modules/extensions/libglx.so.1.0.9629
and substitutes the link with its own regular file,
this leads to warnings about the impossibility to initialise the glx driver when
restarting the xserver and to system instability and lock up as soon
as you perform some operation like opening an image file (jpeg in my case).
Maybe the deb could be tweaked to check if non debianized NVIDIA drivers are installed?

Best regards,
Tito

Isn't this rather a bug in your Nvidia package, which overwrites things on your system without properly using the package management system? Everything under /usr/lib is supposed to belong to a .deb package and be handled by this system.

This is the theory which as usual differs from the reality as,
more often than not, there are no .deb packages with the latest
NVIDIA drivers.
BTW, i don't think you would overwrite a configuration file in /etc if it
was tweaked by the user or would you?

A configuration file under /etc is not under /usr/lib. Read the standards if you want.

I think the "envy" package is exactly this, latest Nvidia drivers properly packaged.

This bug is still not fixed. I just updated to oneiric and had to fix all the glx links by myself.
There is a libglx.so link unter /etc/alternatives. It would be great if the xorg package would link to it, so that an update doesn't break the nvidia configuration. Example:
/usr/lib/xorg/modules/extension/libglx.so links to /etc/alternatives/libglx.so

Then for a normal install:
/etc/alternatives/libglx.so could then link either to the xorg-libglx.so or to /usr/lib/nvidia-current/xorg/libglx.so

This would work around touching upon the /usr/lib-files....
