dmesg|grep "nouveau|drm"

My HP Pavilion dv9560eg sports a 8600M GS video chip with a design defect (for the interested: http://www.scribd.com/doc/19308567/Nvidia-Class-Action).

Good thing is, under certain circumstances it may still be used.

1. Sometimes it boots up just normally and works for a certain time (hour or so).
2. If #1 fails I have to set "nomodeset" to actually see something, otherwise (when the mode gets set) the screen get white and fades to grey in an awkward
way. I can still blindly login  or use ssh.

With "nomodeset" only the first line, otherwise all of those lines can be found in dmesg.

Unfortunately I haven't logged dmesg output in the few moments the machine boots up normally.
