nouveau on NV17: screen remains black with randr12 on

Nouveau works quite fine without randr12. When I activate the Randr12 option, the screen remains black.

I have difficulties to stop the server or even reboot. I type Ctrl+Alt+Backspace and Ctrl+Alt+Del several times. The screen comes back to the virtual console but is like being slowly flooded of white fluid (picture to come).

I finally manage to see the graphical shutdown screen (usplash on Ubuntu) but the screen dispa corrupted GDM Ubuntu theme (another picture to come). And the computer finally reboots.

I attach the X logs with and without Randr12, xorg.conf and captures of the screen corruptions.

The version is the Ubuntu package by raof updated daily. It is dated "Sun Jan 20 18:38:11 2008 +0000". Libdrm2 is also updated daily from a snapshot.

I now have deinstalled the graphical boot but no change.

A log from a happy working session.

X log with randr12

This time the screen remains black, and hard to reboot the computer.

the xorg

I comment and uncomment "Option 'Randr12' True" for my tests.

screen blooming

You could also see the VC 1 text below, but at this time it was blank. I shot other impressive ones!

I think the structure being drawn would help you identify the nature of the corruption.

A last note: obviously I can switch to a git checkout to test patches and bisecting.
Comment 7 Stuart Bennett 2008-01-31 05:35:10 UTC 
Is this now fixed?
Comment 8 Hervé Cauwelier 2008-01-31 05:44:44 UTC 
Yes it is!
