Tim Hull, thanks for your input. In discussing this with other Ubuntu X developers, we've concluded that reverting back to -i810 for everyone isn't an option. (Describing this approach as "irresponsible" is not a constructive way to help resolve this bug.)
I've (finally) been able to reproduce this issue myself. I have to say that while it's certain a bug, the steps to trigger it seem rather obscure to me, and not ones I'd expect an average user to run into very often. But perhaps there are certain use cases (3d games?) that are affected by it more intently than mine. Given how much I've been able to use my 945gm system without triggering this issue, I don't feel like this is a showstopper issue. It does not prevent installation from succeeding, nor prevents X from starting up, and only occurs intermittently with use, so this seems well suited for rolling out post-release, once the issue is fully understood and solved. Investigating further upstream, both Debian and Xorg have reports of similar issues: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=431373 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=432110 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=433825 https://bugs.freedesktop.org/show_bug.cgi?id=9415 https://bugs.freedesktop.org/show_bug.cgi?id=12072 https://bugs.freedesktop.org/show_bug.cgi?id=10833 -- 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
