Hello, Eight days ago, I applied "Workaround C" (upgading to the 2.11.0 xserver-xorg-video-intel driver, from https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes). Note that upon reboot I could not get the normal Gnome logon screen but instead had the following errors: " ! Ubuntu fonctionne en mode graphique dégradé. L'erreur suivante est survenue. Vous aurez peut-être besoin de mettre à jour votre configuration pour résoudre cela. (EE) Intel (0): No kernel modesetting driver selected. (EE) Screen(s) found, but none have a usable configuration. " the "No kernel modesetting driver selected" message made me think to the "Workaround A", which I applied immediately. Then after rebooting the logon screen returned to normal state.
Since then I had about 4 hangs, and I am using my computer only about 1h30 a day... The 3 or 4 last hangs were different: the GUI was completely frozen: it did not answer the mouse or keyboard clicks (the mouse pointer was movable though). However I could CTRL-ALT-F1 and get a text logon and then could issue a "sudo reboot": may be there is a smarter thing to do than reboot ? before rebooting I did a "dmesg": the relevant errors are the same than in my previous post (#194): " [17866.396057] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [17866.396072] render error detected, EIR: 0x00000000 [17866.396121] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 439601 at 439600) [17937.484046] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
