Hi Seth, One bad experience I have had since installing the patched kernel. After countless good boots I decided to add the following lines to /etc/tc.local in order to use switcheroo:
chown "username" /sys/kernel/debug/vgaswitcheroo/switch # change "username" with your user name echo OFF > /sys/kernel/debug/vgaswitcheroo/switch Everything seemed to work for the first 5 or so boots but then I started getting the blackscreens again. The message was similar but not the same. Unfortunately I didn't manage to get a screen of it. Once I got back into my desktop I removed the lines from rc.local and then the issue disappeared. I've gone ahead and added the lines again to see if I can recreate the issue but so far nothing. Not sure if this info is of any use to you at all but I thought I would share just in case it would. -- 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/727620 Title: [Radeon HD 5650 and 5470] Kernel BUG during recovery boot and in normal boot (Hybrid graphics) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/727620/+subscriptions _______________________________________________ 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
