LinuxQuestions.org - Linux unable to load KDE

Hi,

I am a Linux newbie. I just installed Mandrake Linux version 9 on my PC. When I booted after installation, I was only able to log on through the console. The desktop did not load and when i tried to run KDE from the command line, the screen went blicked several times and came up with the following error;

(EE) Screen(s) found but none has a usable configuration.
Fatal server error: no screens found

Someone told me to run the desktop using cttrl/alt/f7 but when I did, the screen went black and a cursor continued blinking at the top of the screen. I had to press ctrl-alt-del to shut down

I'll appreciate anyone who can help. Thanks!
