When I boot all seems to go well at first. But after the log-in screen a message pops up: "Oh no! Something has gone wrong" etc. I am advised to log out and back in again, but the problem occurs every time. The weird thing is that when I hit the windows-key the ususal X-screensaver appears. But when I try to launch an application I get an black screen with the error message again. When I boot in rescue mode and try to start X it fails. Jatin K wrote:

Peter: did the error message look like http://estrip.org/content/users/tinypliny/1111/IMG_20111117_083221.jpg
If so, it's a Gnome error message, not X, and the chances are that X itself is fine.
Try creating a brand new user and logging in under that ID.
Are you fully up-to-date?
Yes that is the message get. So it is a gnome//error. I tried your suggestion but after logging in under the new user I get the same error. I also looked for a file xorg.conf in /etc/X11, but there is no file called like that. Thanks for your suggestions. Peter
