Simon K, would disabling the discrete graphics card in BIOS be an additional available method?
As well, given the issue appears to be identified with vgaswitcheroo not quite being free of causing collatoral damage, and you have what appears to be an acceptable alternative to disabling your graphics card, would you like to pursue a fix for this, or would disabling the garphics card via upstart-job be considered a solution? ** Tags removed: regression-potential ** Tags added: regression-release -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux 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" Status in The Linux Kernel: Confirmed Status in “linux” package in Ubuntu: Incomplete Status in “xserver-xorg-video-ati” package in Ubuntu: Confirmed Bug description: Symptom: Linux isn't displaying changes after switching to tty1 and back to Unity. Steps to reproduce: 1. Starting up to Unity 2. Switch to tty1 (Strg + Alt + F1) 3. Switching back to Unity or resuming the system from suspend leads to the same isssue.This method isn't as reliable as the method stated above. What happens: The screen freezes. Magic Keys [Alt + Print + S/U/B] are working thou (so linux-kernel is responding?!) I can't switch to tty1 either. The system becomes responding again after ~2min. Switching VTs is possible afterwards but leads to the same bug again. What is expected: Showing up a responding Unity. WORKAROUND: My radeon is switched off using: echo"OFF">/sys/kernel/debug/vgaswitcheroo/switch By turning "ON" the graphics card the above stated problem doesn't appear.
