Comment 36 for bug 114520

i've tried everything i can think of to fix these intermittent freezes and black screens, so i think i am also affected by this bug. sometimes my display and keyboard will freeze, but my mouse cursor can move (though i cannot use the buttons on it), sometimes it will freeze and go to the background color and input devices don't work, sometimes it will black out completely and input devices don't work, and oddly enough sometimes it even goes to "power saving mode" and input devices don't work.
i've tried both i686 and i386 kernel images resulting with the same problem. i've tried everything i could find in the forums and or the wiki to fix this problem via manual configuration of xorg.conf, including commenting out dri and glx and it results in the same problems and the ones suggested in this bug report. i also receive absolutely no errors in any log files.
everything is perfectly fine if i use the vesa driver, except the fact i cannot play games that need dri (which is a big deal to me).
i have tried using other distros and unfortunately windows to test and i am only affected by this problem in ubuntu. i've been using ubuntu since hoary and i'm not going to switch distros because i love where this project is headed and the goals set forth.
i hope the previous comments and the following information has been helpful, minus my own personal feelings/comments of course (please tell me to provide more if this is not enough).
