I just installed 'linux 3.18.0 rc7' : - After regular boot, graphical login systematically fails.
- After a boot in 'recovery mode' (which includes the 'nomodeset' parameter), graphical login systematically succeeds, but Cinnamon complains that the graphical driver lacks support for hardware acceleration, and Cinnamon works in software rendering mode. - After having replaced 'quiet splash' by 'nomodeset' in the 'regular boot' menu entry of 'grub.cfg' and rebooted, the behavior is exactly the same as in 'recovery mode'. I see that you have added a tag requesting a crash log. I am willing to provide it. Can you explain where I can find a crash log, or how I can trigger its generation ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396840 Title: Module nouveau systematically crashes after a few minutes, whereas module nvidia from nvidia-331-updates crashes only after several hours of work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1396840/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
