Hi Dana, okay, radeontool might be useful in debugging this. After installing it, you run it like this:
radeontool regmatch '*' > regdump_good.txt radeontool regmatch '*' > regdump_broke.txt Run it two times. Once when you have a good, working screen (for any driver including -vesa), and once in the broken case (either from the tty console or logged into the sick box remotely). ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Confirmed => Incomplete -- [lucid] Broken backlight control with Radeon open-source drivers https://bugs.launchpad.net/bugs/534677 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
