I can confirm that reverting to 2.6.24-24 from ubuntu archives solves the problem. I'll attach to this report the output of radeontool for the "good" case (i.e. running 2.6.24). At the moment I need using the computer to which the video card is attached, but later I'll try to run the same command in the bad case.
By the way, running radeontool seems to kill the output: I'm presented with a black screen and the only way to have output back is to reboot. Is this normal? ** Attachment added: "output of radeontool regmatch '*'" http://launchpadlibrarian.net/23778076/regdump_good.txt -- Intrepid Upgrade+Live CD: Radeon RV280 9200 Blank Screen https://bugs.launchpad.net/bugs/297119 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
