After installing RH 7.1 I had these problems.
(1) Monitor would become hot to touch.
(2) Some of the key's on key board would not function.
(3) When clicking on cd-rom,control panel icon in KDE desktop,the screen would freeze.The only way out was to switch the computer off.
I believe my X configuration settings were ok,x&y deflections as specified in product specs. of monitor.I am running a dual boot system with Win 98 SE.I choose a partitionless install into D drive.
