Yes, the issue with this is: xserver-xorg-video-intel 2:2.15.0+git20110706.0be47f45
If you are using an Intel graphics chipset (I have a Thinkpad with a similar setup and had similar issues). The best way to work round this for now is to download and install: https://launchpad.net/~xorg-edgers/+archive/ppa/+build/2589725/+files /xserver-xorg-video- intel_2.15.0%2Bgit20110624.471115a9-0ubuntu0sarvatt_amd64.deb (From page https://launchpad.net/~xorg- edgers/+archive/ppa/+build/2589725) This should get round things for the short term. I also noticed when I installed any later versions of this package that were built between now and 471115a9 that my X display would randomly go black and refuse to switch modes (i.e. switching to a TTY by pressing Ctrl + Alt + F2, etc wouldn't switch the display, but otherwise did allow me to switch to TTY to gracefully reboot by three finger salute). Likewise SAK (Sys Req + Alt Gr + K wouldn't reset X) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/806548 Title: [xorg-edgers] Desktop gets messed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/806548/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
