Hi everyone, During last upgrade, the glx-alternative-nvidia package (0.6.91 / unstable) failed to configure. Here's the output :
>root@GOGI: apt-get upgrade > ... > ... > Treatment of deferred shares ("triggers") for nvidia-glx-alternative (0.6.91) ... > update-alternatives: error: The /etc/modprobe.d/nvidia.conf alternative link > is already managed by nvidia > dpkg: package error processing nvidia-glx-alternative (--configure): subprocess installed post-installation script returned error exit status 2 > ... > ... > Errors were encountered while processing: nvidia-glx-alternative > E: Sub-process / usr / bin / dpkg returned an error code (1) and > root@GOGI:/home/gogi# dpkg -l | grep glx-alternative-nvidia > iF glx-alternative-nvidia 0.6.91 amd64 allows the selection of NVIDIA as GLX provider Actually my Debian Sid system was running on the experimental nvidia driver version (352.41-1) when this happened. When I restarted it, I fell on tty login screen instead of gdm login one. This was caused by the failing configuration process, as the nouveau driver was loas instead of the nvidia one, because of no more "nvidia-blacklists-nouveau.conf" file in /etc/modprobe.d which should normally blacklist the nouveau driver. Doing it manually solves the problem. I tried to downgrade nvidia-driver to unstable version (340.93-4), thinking that it may solve temporarily the issue as its version from unstable repository or some of its dependencies may not be already compatible with glx-alternative-nvidia (0.6.91), but that operation neither could be done, as the glx-alternative-nvidia package which is pushed in unstable repository (0.6.91) breaks some of the dependencies (as i.e. nvidia-alternative (<340.93.-5), while the version available in unstable is still (340.93-4).
