I found workaround for GPU lockups (X freezes) on Intel i845 hardware at official Xorg bug tracking system - see http://bugs.freedesktop.org/show_bug.cgi?id=26345
It's very simple - just create a /etc/X11/xorg.conf config file with this content: Section "Device" Identifier "Card0" Option "DRI" "false" Option "Shadow" "true" EndSection I'm attaching xorg.conf file which fixes GPU lockups on Intel i845 hardware. Also I found more info about solutions how to fix GPU lockups on Intel i845 and i855 hardware at LP bug #541492 and bug #541511 ** Bug watch added: freedesktop.org Bugzilla #26345 http://bugs.freedesktop.org/show_bug.cgi?id=26345 ** Attachment added: "xorg.conf which fixes GPU lockups on Intel i845 hardware ("DRI" "false" and "Shadow" "true" in Section "Device" )" https://bugs.launchpad.net/baltix/+bug/860728/+attachment/2513021/+files/xorg.conf -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/860728 Title: Xorg freeze in i845 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/860728/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
