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. |
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)

Gnome-Session 3.8+ enforces usage of 3D, breaking usage of all gnome-session based sessions in non-3D accelerated environments as non-3D enabled hardware, forwarded-X, VNC and NX/X2GO.
This breaks gnome-flashback, breaking upgrade path from previous LTS and removing most sane option for cloud environments!
Overriding 3D checks (sym-linking /usr/lib/gnome-session/gnome-session-check-* to /bin/true) allows to start the session but it fails few seconds later when gnome-session segfault without apparent reason.
