Monitor flickers at random times

linuxbotx · 10-29-2003, 10:33 PM

I'm running SuSE 8.2 with an AOC LM500 LCD monitory, Geforce 440 MX 64mb ram.

This just started recently for no reason, my monitor flickers randomly. My screen will go black for about a second, and back to the desktop. It does this in KDE, Gnome, Window Maker, and while playing any games on Linux (ie Jedi Knight 2 or even RTCW). Strange. I tried changing my monitor type, resolution, and color depth, and it still does it. I do have the nvidia driver installed and configured in my XF86Config file, I even tried taking it out. It flickers this with and without the driver

Any Ideas? This is getting really really annoying.

Maybe your monitor is broken? Does it do the same in Windows (if you use it)?

Also, is the monitor light (the one next to the "on" switch) lit up during this flicker? Could be a power problem. Do you hear any arcing at any stage?

I've seen similar behaviour caused by an overheating nvidia video chip. Seems unlikely if there is a fan on your video card tho'. Otherwise if you have easy access to your hardware test the temp of the big chip on the video board with your finger (from back of board as usually some kind of heatsink on the other side). Too hot for comfort? That seemed to be my problem. Probably only solution then is to increase airflow over the heatsink, or change the card.

My monitor light is on when it flickers. I wouldn't know if it does it in Windows or not, I don't use windows. I think maroonbaboon is right, it could be from overheating. Having a dual processor does seem to get my PC a little warm, but I do have a fan blowing all air out of my PC anyways. Well, I shutdown my PC over night, and so far, no flicker. I'll keep this forum updated. Maybe its time for me to finially get that Nvidai Geforce FX 5900 now

Naturally. Sydneysiders are always right. This of course means I was also right but you are a special case (you know the kind that prove the rule). Hehe.

Well, it wasn't the video card. The flicker started about 20 minutes in. I switched out my LCD monitor with my CRT. It was the monitor. I guess the monitor has just about had its days. I havn't had any flickers with my new monitor, so I guess its time for a new LCD

Good to know it's solved.
