Seems to be ok. You may want to explicitly specify the 'Virtual' screen size. Then, you may want to check permissions on the configuration files, specifically /etc/X11/xorg.conf Then you may want to compare the output of X to see if there's any difference between doing startx as root or as a normal user. I expect there to be a difference between the two. Regards, David
