Bug Description
Binary package hint: xserver-
This has happened immediately after I upgraded to Ubuntu 11.04. Kernel 2.6.38 is not booting and shows junk on the screen.
I tried a USB pendrive (USB pendrive works with Ubuntu 10.10) and I get a black screen.
After grub has disappeared the system starts booting, and after some seconds I get a screen screwed up. Cannot switch to virtual terminals and cannot connect via ssh.
With the USB pendrive more or less the same happens. After I click start, nothing else appears on the screen and the boot procedure stops.
The only way I found to get both systems start is to add nomodeset parameter. With this the system starts.
The same system starts with kernel 2.6.35 without the nomodeset parameter. Anyway, since I upgraded to Ubuntu 11.04, I'm experiencing some sudden logouts and frequent complete screen freeze when in dual screen.
The Ubuntu kernel team suggested to try kernel 2.6.39-

Hey, as I said on irc we need the /var/log/kern.log that contains the kernel boot messages with the bad kernel. Add 'drm.debug=14' to the kernel boot options, so that the kern.log would contain plenty of debugging information. Attach the logfile here.
