It looks like radeontool fails silently, instead of telling the user to run it under sudo. I also had to escape the asterisk to pass it to radeontool: sudo radeontool match \*
Here's my radeontool output on 2.6.34-rc5 kernel from kernel-ppa -- this is the "broken" case. I can't seem to recall a time it ever did work with the open-source drivers (either UMS or KMS). ** Attachment added: "radeontool.log" http://launchpadlibrarian.net/47155072/radeontool.log -- [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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
