I have exactly the same symptoms as in the comment #12, except that I cannot even shut down my computer by using the power key (except with a long press, which does a HW power off). I haven't yet tried the SysRq method - I'll try the next time the freezing occurs.
I get the issue sometimes when booting up, and sometimes when the computer has been left idle for a while (I don't know if that is just a coincidence). During the boot-up, I sometimes do get a non-blinking text cursor "_" in the top-left corner when the computer freezes. I'm having a bit different HW, though: i830M. It also has the flicker issue (though maybe not identical with this bug report), which I've filed in the bug #477264. Here are a couple of patches that might help in the issue, but unfortunately I haven't so far had the time to apply them and compile the kernel in order to test if they help: http://lists.freedesktop.org/archives/intel-gfx/2009-September/004122.html http://lists.freedesktop.org/archives/intel-gfx/2009-September/004128.html -- [i865] karmic: 865g is pretty unstable https://bugs.launchpad.net/bugs/407587 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ 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
