radeontool can be used to assist in debugging issues where the screen blanks like 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 -- Black screen on workspace transitions https://bugs.launchpad.net/bugs/542533 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
