I did some further testing after installing the current daily image (only possible by booting the usb stick with "nomodeset").
It seems to depend on the boot options if the system comes up properly with Nouveau drivers (and KMS). Booting with just: quiet splash splash or no options specified as kernel options makes the system come up properly (even with 3D acceleration, allthough with bug #1010794). Otherwise, if I boot with: ro quiet splash $vt_handoff quiet splash $vt_handoff ro quiet splash it leads to the unusable desktop/login manager as reported in this bug's description. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1040495 Title: Graphical corruptions with Nouveau driver makes Quantal unusable Status in “xserver-xorg-video-nouveau” package in Ubuntu: New Bug description: Hello, since a few weeks I effectively can't run Quantal anymore due to strong graphical corruption when using the Nouveau driver (I have a Geforce GT430 card). To reproduce, I just have to boot a daily live image from a USB stick. The followings happens (as shown in the camera screenshots I'm gonna attach): - The boot logo (shown by Plymouth) is distorted - Then for some seconds a very weird looking corrupted screen appears - Then the desktop has loaded, but shows only corruptions instead of the wallpaper - The dock on the left screen side is shown correctly, but it's not possible to start/use any application - The mouse cursor isn't shown, due to "shades" of tooltips you can sometimes guess where the cursor might be This is a regression from Precise and early Quantal, where Nouveau drivers worked much better. To report this bug, I had to boot the daily live image with the "nomodeset" option. Even the new software-rendered Unity desktop you get in this case is barely usable due to heavy repainting issues, but that might be another bug.
