Description:
This is really hard to explain, so I attached a picture. Basically, sometimes my laptop (a Dell Latitude E6410 with integrated Intel graphics, WXGA+ panel) gets a corrupted screen X is about to start. This doesn't happen every time. Maybe one out of every five boots or so. When I reboot it, it may or may not launch X correctly. When it does happen, the entire panel gets pixelated and gets brighter and brighter until it's almost all white. I can reboot the laptop when this happens by switching to a tty and rebooting from there. I can't see the tty, just the garbled colors. But I can still execute the commands in the tty by just entering my username/password and "sudo reboot" without seeing the screen, from memory. I'm not sure what the trigger is, but I know it happens a bit more often with 2.6.37. Steps to reproduce: Unfortunately, I've not determined any pattern.

I also had a chance to test 2.6.38 by installing kernel26-mainline from AUR. On that kernel, I do not have this problem. But, with that kernel the backlight won't turn on after resuming from sleep so I'm trading one problem for another.
