[Problem]
External screen with VGA shows corruption when enabled, and if mirroring set both screens show corruption.

[Original Description]
I am attempting to set up dual monitors for the first time in ubuntu. I recently upgraded to 10.04. on both monitors I have the image I get is corrupt on the monitor, and if I set it to mirror the displays my laptop screen becomes unresponsive and everything on it is whiter. I am trying to set this up through vga. I can still move the mouse around on the corrupt screen and see it fine.

Does it work correctly if you boot without the VGA monitor connected and then enable it after X loads?

I have a similar problem than Bryce Harrington.

If I start my laptop with the second monitor plugged in, every thing is fine until i login. After I have the same as Bryce corruption on both screens.

If i start my computer without the external display plugged in, every thing is fine. 
If I plug the second screen after X started nothing happens (normal). But as soon as I launch xrandr from a console both screens goes wrong again. It goes back ok when I unplug the external display and relaunch xrandr...

I have the same problem on my Hp nx7000
Comment 10 Alex Deucher 2010-10-19 19:27:05 UTC
Is this still an issue with a newer version of the kernel or driver?

Invalid downstream.
