Using xf86-video-i810 v1.7.4 (which is the REAL i810 driver, not the generic intel one) fixed the hanging bug for me.
As far as I have experienced, the intel driver corrupts X memory then X drops mouse and keyboard - making the system unusable Please spread the word that xf86-video-i810 v2.x (which actually uses xf86-video-intel code) is NOT stable -- laptop hangs when switching video mode https://bugs.launchpad.net/bugs/127101 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
