I must add two boot parameters (nouveau.debug=trace and drm.debug=0xe) by changing my GRUB configuration. Then, I reboot and look at the logs (dmesg, I suppose? Or maybe also Xorg.0.log?). Then I give a look to the nouveau source code to see if I find some suspect. Am I right? Please note, however, that I'm a Java developer and I know nothing about Linux programming. So I don't think I will be able to understand too much from the nouveau source code :-P > Unfortunately this is getting well outside of my knowledge area.

So, put in other words: could it be useful to look at the monitor-get-edid source code to try to understand why it is working while nouveau is not?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
