I'm relatively new to Linux. tried to install Redhat 5.2, failed, installed Caldera 2.2, it worked. Boot magic inabled me to run several partitions, Win98, win 3.11, and Linux. Next installed Mandrake 6.0 over Caldera, then upgraded to Mandrake 6.1. I have a 8.4 gig HD, AMD 300 chip. Now the problem: ( it started with Mandrake 6.0) The screen will lock up. The mouse arrow moves but clicking on anything produces nothing. At first I tried rebooting , (the Win98 method) it scrambled things, all kinds of errors on bootup. A friend streightened it out so I can get into Linux but the "screen lockup" still continues. It locks up when I try to "shutdown". Clicking logout gives the "logout screen" but clicking "Shutdown" locks up the Screen. It does it in KDE, GNOME, user or root. To exit now I either use Ctrl+Alt+F2, then Login as "root" ,password, "Halt". Or I go into the terminal, then "su", password, "halt." Thanks for the help. Stan
