[pkg-nvidia-devel] Bug#596898: libgl1-nvidia-alternatives: Updating almost any package breaks dri

[Ingo Kasten]

Package: libgl1-nvidia-alternatives
Version: 195.36.31-3
Severity: important

Hi,

Since nvidia driver 195.36.31-2 I experienced a strange problem.

After most updates of any package direct rendering has gone. Reinstalling
libgl1-nvidia-alternatives solves the problem with the following warning:

update-alternatives: warning: forcing reinstallation of alternative
/usr/lib/nvidia/libGL.so.1 because link group libGL.so.1 is broken
(in german:  update-alternatives: Warnung: Erzwinge Neuinstallation der
Alternative /usr/lib/nvidia/libGL.so.1, weil die Linkgruppe libGL.so.1 defekt
ist )

This is the reason why I assign this bug to the package libgl1-nvidia-
alternatives although I do not know if it is the guilty one.

The only updates that did not show this behaviour were
foomatic-filters
grub

Most times (except for KDE- or X- related stuff) I use synaptic / KDE4
(testing/sid) for updates.

regards
Ingo
