Screen stays black when changing display

[Theo Band]

Binary package hint: xorg

If I change the display from external display back to laptop, the screen stays black. Only the mouse pointer is visible.

I can also reproduce this with this command:

xrandr --output LVDS1 --rotate right

The screen is black and does not longer update. I can switch to a VT and back to the VT-7. The screen than show the previous VT-1 terminal screen and my mouse hovers over it.

xrandr --output LVDS1 --rotate normal

Rotates the screen back, but the screen itself does not update. (pkill -9 -u $USER restarts the session)

Note that this problem does not always occur. I just retried after writing the above update and rotating works correctly.

Hey theo-band,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

[Theo Band (theo-band)]

This problem does not exist in Ubuntu 11.11
Don't know how to close this bug.
