hi, I'm Gursimran singh Mohar. I work for Ubuntu Bug control team. Someday I hope work for kernel triaging also. I have a display problem that I would like to share here. My laptop Sonay vaio(VPC CW 16FG) has Nvidia 230M GPU. The laptop ends up in a blank display when booted directly into maverick. This is possibly caused because the driver (nouveau) is not able to read the EDID information of the display attached to laptop. These are some of the fourms that discus the issue ... <a href="http://www.nvnews.net/vbulletin/showthread.php?t=140482&page=5" target="_blank">http://www.nvnews.net/vbulletin/showthread.php?t=140482&page=5</a> <a href="http://ubuntuforums.org/showthread.php?t=1470822">http://ubuntuforums.org/showthread.php?t=1470822</a> I start the computer by adding a 'nomodeset' in the boot parameters( <a href="http://lemoney92.blogspot.com/2010/09/linux-blank-screen-problem.html">http://lemoney92.blogspot.com/2010/09/linux-blank-screen-problem.html</a>). But using mainline kernel linux-image-2.6.36-999-generic_2.6.36-999.201010271121_i386 however, I'm able to boot into directly. It works absolutely fine. Now I wanted to help somebody as a tester, if somebody could provide some ubuntu specific patch work and talk to upstream kernel team about this. using this linux-image-2.6.36-999-generic_2.6.36-999.201010261121_i386 and all previous the problem perists. I'm attaching some videos that are made booting from the two kernels. -- Warm Regards, Gursimran singh Mohar
