Today - on my machine with the intel graphics chip - I experienced a second freeze that again stood out a little. Luckily a camera was in grabbing range :P

This is the second freeze in a row that happened while activating the compiz scale feature. All the other freezes before I just can't remember. It might be that these all have been "scale"-related, too.

While my computer was frozen I tried the obligatory key combo "alt-sysrq-k" it took about 30s and the well known reaction happened: Screen is black with a thick blue stripe on the right side. See here http://pkqs.net/~cf/small-IMG_1303 .

After pressing "alt-sysrq-k" several times this known window appeared: "Ubuntu is running in low graphics mode" - also saying: "(EE) intel(0): Failed to set tiling on front buffer: rejected by kernel". See here http://pkqs.net/~cf/small-IMG_1304 .

Then another window appears asking you what to do. See here http://pkqs.net/~cf/small-IMG_1305 . I chose "Exit to console login". This put me on tty1 but totally screwed up - I wasn't able to type something blindly. See here http://pkqs.net/~cf/small-IMG_1307 . Going back to the console where gnome was running on showed this here http://pkqs.net/~cf/small-IMG_1308 .

After pressing "ctrl-alt-backspace" my computer performed a shut down.

Any reactions on this?
