ruediger.kupper: Acceleration check can be skipped by passing --disable-acceleration-check to gnome-session
chris-good: I might be wrong but by 3D acceleration, VM hypervizors usually mean H/W 3D offloading to host GPU. Also usually VM para-virtualized drivers support direct rendering and all most X11 extensions which can be used by Mesa (pure software or LLVM-pipe) to simulate 3D. Regarding Unity, it uses Compiz which also supports Mesa simulated 3D (at least in recent versions). Environments like NX/VNC/RDP and etc, usually lack direct rendering and most X11 extensions therefor 3D simulation is broken. It's sad that this fact is ignored by distributions and desktop environments developers and we are enforced to deal with it here :-( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1251281 Title: gnome-session-flashback fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-session/+bug/1251281/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
