Comment 10 for bug 117651

Gregor:
This is probably the wrong bug to report your particular issue. There's a very small chance given that you are using an AMD that you are seeing Bug #109643 . Further, since you are using manually installed NVIDIA drivers (100.14.09) unless you can reproduce the problem with the open source nv driver then your support options have changed as you are using an NVIDIA package not distributed by Ubuntu. Any problems that occur after installing drivers not provided by Ubuntu repositories should not be reported to the launchpad bug area. If the drivers were downloaded from the NVIDIA web site then the NVIDIA Linux web forum (http://www.nvnews.net/vbulletin/forumdisplay.php?f=14 ) is an appropriate place to report issues. If a 3rd party installer was used please contact the 3rd party for support. Other places for manual driver support can be found on the Community Support page (http://www.ubuntu.com/support/communitysupport ).
