Comment 6 for bug 450669

tiago, you should file a new bug report rather than me-to onto this one. Your pictures don't match the original description, and besides this bug report is closed.

I would recommend testing a natty livecd and see if you can reproduce the issue. If you can, then file the bug using the command `ubuntu-bug xorg` from a natty session.

If you're just looking for a workaround to the problem, you might try asking at askubuntu.com for technical support.
