Hi, Sanjoy Mahajan <sanjoy@olin.edu> (22/02/2011): > Alas, yes: I still see the problem. I see you're running 2.6.37, and it looks like there were some more backlight fixes lately, so you might want to try latest 2.6.38-rc from experimental. You could also try building the intel driver from upstream git master (I can assist with that part). > Since then I've added "drm.debug=14 log_buf_len=16M" to all grub > boot-command lines (copied from a Fedora "debugging X" page).

I'm afraid you'll have to ask upstream. Bug reports of interest: https://bugs.freedesktop.org/buglist.cgi?cmdtype=runnamed&namedcmd=Driver/intel https://bugs.freedesktop.org/buglist.cgi?cmdtype=runnamed&namedcmd=DRI/Intel If you see nothing matching your issue, I'd suggest reporting a bug there: https://bugs.freedesktop.org/ product xorg, component Driver/intel should be a good start.
