Hi Sergey "Shnatsel" Davidoff, radeontool can be used to assist in debugging this issue. To install it from the command line, use this command:
sudo apt-get install radeontool 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 working screen (for any driver), and once in the broken case (either from the tty console or logged into the sick box remotely). Attach both of those to this bug report, and we can then forward this issue upstream. Thanks ahead of time! ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. https://bugs.launchpad.net/bugs/725580 Title: black screen on boot on radeon 9200 _______________________________________________ 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
