I have the same error at intel_set_mode+0x25/0x30 [i915]. X won't always come back to login screen, but screen turns black and every X client dies.
I can reproduce it consistently by triggering resolution changes. Important information: I am using kde with kwin as window manager (this appears to be OP's case as well, since his "InstallationMedia" is listed as "Kubuntu 12.04"). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1251873 Title: X crashes back to login screen when running firefox, chrome, etc. To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1251873/+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
