What is needed to track down this (very annoying) bug? I'm seeing the same issues, but unfortunately this bug is really hard to reproduce. In my case I usually (but not always) can reproduce it like this
- switch to integrated graphics in bios (intel) - boot - gdm autologin into unity --> everything works fine - shutdown - switch to ATI graphics card in bios (ATI Technologies Inc Mobility Radeon HD 3650) - boot - gdm autologin into unity And then the only wallpaper is displayed, but no unity or anything else. Then repeatingly every 3 or 4 seconds the screen gets black and the wallpaper is displayed again. Switching to a console and running "service gdm restart" as root brings up unity without further issues then. Attached is the output of dmesg before restarting gdm. Please let me know if you need additional information. ** Attachment added: "dmesg output" https://bugs.launchpad.net/unity/+bug/772513/+attachment/2183231/+files/gpu_lock.dmesg.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772513 Title: Unity crashes on non-mirrored displays To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/772513/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
