Bug Description

When I run a Remote Desktop Session to a windows host - either local on my machine in a VM or remote - the cursor appears in a garbled square - maybe 20x20 pixels.

The square seems to show some of the content of the windows hidden by the Remote Session application.

I tried this with a variety of different Remote Desktop Applications - and all have the same issue, when the cursor in the Remote Session is not an arrow, it is scrambled.

I also found that with Remmina, the problem does not appear - because the cursor shape never changes.

I cannot get a screenshot of the behavior - taking the screenshot somehow resolves the problem - but only for the fraction of time that the screenshot is taken.

I have played around with this issue some more. For as far as I can determine the problem only appears to affect RDP sessions; VNC sessions do not seem to have the problem.

FWIW...

Ok - the problem seems to be related to the fact that I had two monitors set up - split over two graphics cards (the onboard and a second card). As soon as I disabled one of the two monitors the effect disappeared.

 I've installed a different graphics card that allows me to run both monitors from the same card and the problem appears to be resolved.

Still - I'd not have expected this behavior, and I can hardly imagine this is "as designed". Furthermore, when I also couldn't get the system to properly recognize the second monitor - something that now works ok.

Maarten Jacobs, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg REPLACE-WITH-BUG-NUMBER

Thank you for your understanding.

I can retest this, but it'll be a bit before I can get round to this as I'll have to build a test platform with the right configuration. I'll post the requested additional data when I'm able to recreate the problem.
