I'm using a "radeon 9200" 128m video card. My monitor is a Hanns-g...It is not a name brand computer. Everything started out well until i created a wireless network with a AT&T Router/modem..everytime i connect my monitor "turns off" .Running the software 'WAS" ok until e-net connection? And now the monitor turns off and i cant reload the software? O and i'm using fedora 10 cambridge..or trying to anyways..lol
I must say this sounds very strange...
What happens after the monitor turns off? Does the actual power LED inidicator on the monitor turn off? Can you turn the monitor back on? Or do you have to reboot the PC? Have you tried accessing a Virtual Terminal? You can do this by pressing Ctrl+Alt+F1 (or F2,F3, etc.) key combo. Then log in as root, and try these commands, to get some possible clues:
if you can't access a VT, can you ssh into the box from another PC? If so, then you can run the above commands that way.
