gnome-session: where to put "--disable-acceleration-check"

  • 772

After I've install properitary nvidia drivers in my Ubuntu 14.04.5 (Kernel 4.4.0), I am not longer able to start the display manager or remote session via thinlinc. /var/log/syslog reports

gnome-session[4058]: WARNING: software acceleration check failed: Der Childprocess exited with status 1
gnome-session[4058]: CRITICAL: We failed, but the fail whale is dead. Sorry....

Concerning this post [1], it is possible to bypass the acceleration check, but I don't know where to put the flag --disable-acceleration-check. Can someone help?

  1. Building on DomQ's answer above, try this for /etc/X11/Xsession.d/98-gnome-session-disable-acceleration-check

    case "$STARTUP" in
     *gnome-session*)
       STARTUP="$STARTUP --disable-acceleration-check"
       ;;
     *x-session-manager*)
       if $(/usr/bin/update-alternatives --query x-session-manager|grep -q "^Value:.*gnome-session")
       then
         STARTUP="$STARTUP --disable-acceleration-check"
       fi
       ;;
esac

    Edit: it looks like update-alternatives is located in /usr/bin instead of /usr/sbin in recent versions of Ubuntu. I've updated the above script to match the new location. If you're not sure where update-alternatives is on your system, try running "which update-alternatives" in a terminal window.

  2. Create a file called /etc/X11/Xsession.d/98-gnome-session-disable-acceleration-check containing

    case "$STARTUP" in
     *gnome-session*)
       STARTUP="$STARTUP --disable-acceleration-check"
       ;;
esac
