So I found out, why those "hangs" occur (or better: how to "heal" them): till now I've had a script in my "autostart"-section which essentially just disabled the dgpu (the power-gpu). It seems like X.org or something isn't happy with getting "robbed" a card while it is running.
So my solution/fix is: Deaktivating the card before X.org is even started, by setting up an Upstart-Job: $ sudo nano /etc/init/disable-gpu.conf # content at: http://paste.ubuntu.com/6131570/ Now everything (including Audio, which had a "separate" bug) works fine, no hangs at shutdown, no problems at suspend/resume, no problems at VT- switching. -- 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/1062077 Title: [HP TouchSmart tm2-2010eg] Linux hangs with: "[drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting" To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1062077/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
