With latest kernel and xserver-xorg-video-intel the system has become usable with ambiance theme. I also needed to xserver-xorg-video-fbdev package.
Before I installed xserver-xorg-video-fbdev the behavior was: 1. ubuntu classic (no effects) on AC - OK 2. ubuntu classic (no effects) on battery - mild crash (ambiance theme changes to clearlooks). This crash no longer requires reboot, X restart by logout is enough. 3. ubuntu - mild crash With xserver-xorg-video-fbdev: 1. ubuntu classic (no effects) on AC - OK 2. ubuntu classic (no effects) on battery - OK 3. ubuntu - mild crash I can help with testing/data collecting if anyone is interested to find and fix this mild crash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/742175 Title: [i915] xserver crashes abruptly (OOM?) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
