    Hi everyone,<br>
    <br>
    During last upgrade, the glx-alternative-nvidia package (0.6.91 /
    unstable) failed to configure. Here's the output : <br>

    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.<br>
    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.<br>
    Doing it manually solves the problem.<br>
    <br>
    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).<br>
