You mentioned this occurred after upgrading xserver-xorg-video-intel. That may be coincidental, but if not (i.e. if downgrading to the previous version makes the freezes stop), the first thing worth looking at is switching back to UXA. To test that, put this in your xorg.conf:
Section "Device" Identifier "Card0" Driver "intel" Option "AccelMethod" "uxa" EndSection If that fixes it with the latest version of the ddx driver, then that narrows it to the SNA code. -- 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/1119793 Title: [arrandale mesa] GPU lockup IPEHR: 0x02000000 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1119793/+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
