Title: gnome-session is broken without 3d acceleration, breaking also gnome- flashback on X, VNC and NX/X2GO Status in “gnome-session” package in Ubuntu: Confirmed Bug description: Gnome-Session 3.8+ enforces usage of 3D, breaking usage of all gnome- session based sessions in non-3D accelerated hardware and environments as plat X, VNC and NX/X2GO. This makes usage of gnome-flashback impossible. Overriding 3D checks (sym-linking /usr/lib/gnome-session/gnome-session-check-* to /bin/true) enables sessions start but gnome-session segfault few seconds later. (Sorry for hijacking this bug, but new gnome-session behavior has much broader affect then originally reported) Original report: ---------------- In Saucy Salamander, gdm will not start if 3d acceleration is not available. This throws an error to /var/log/gdm/:0-greeter.log gnome-session-is-accelerated: No composite extension. gnome-session-check-accelerated: Helper exited with code 256 gnome-session-is-accelerated: No composite extension. gnome-session-check-accelerated: Helper exited with code 256 ** (process:4142): WARNING **: software acceleration check failed: Child process exited with code 1 This is a regression from raring, and is the same if gnome-fallback is unavailable. Possibly the same bug as #1251281, as this shows the same error. This is preventing me from upgrading to raring, as I run 4 screens on an Nvidia Quadro NVS 450, meaning 3d is unavailable.
