Bug Description
Binary package hint: xorg
Newly installed 11.04b2 on thinkpad x201, which used to work with 10.04 (with i915.modeset=0). If an external monitor is plugged in then frequently both screens will go blank. Sometimes the external monitor flashes solid red and sometimes there is a flashing distorted image of the screen.
This happens with both a VGA and a digital cable.
This always happens with existing accounts, but if I create a new account, I have been able to get both monitors working at full resolution (1220x1200 for the external), but if I then remove the external monitor, the laptop screen goes blank... sometimes with an X cursor, sometimes without,

With a newly created account, I can get both monitors working, but it
is delicate and if you remove the external monitor or try to change
the display settings, then you frequently end up with black screen
(sometimes with movable X cursor).
Even if I save as default the setup with 2 screens working, if I log
in as the existing user, then I get blank screens.
What files in an account could affect this?
