horizontal lines on screen?


Has anyone had a case of horizontal lines on the monitor screen? It is not the monitor, as connecting the system to another monitor it did not go away. So it must be the graphics card, but does anyone know what to chek next?

Thanks, svar

When do you have the lines? All the time or only when something specific happens?

What happens when you switch to the console mode (ctrl+alt+f1)? If it's OK, there's something wrong with your X settings. I suggest you to install xvidtune (not 100% sure it's the correct name) and use it to test diffeent settings (small steps). Yoour settings are close to good, but the values are not what they should be.

Are the lines moving up and down? If so, maybe your monitor(s) don't support the current video mode/resolution. Use CTRL+ALT+PLUS/MINUS to cycle through available resolutions.

Thanks for the suggestions! Unfortunately I don't think we're quite there yet.

Now, console mode does not change anything: The lines are still there. Second, I did not change anything in view of the resolutions. This was a WORKING installation that decided to have this behavior after a power failure and no, the lines are not moving up and down. These are fairly fuzzy horizontal lines.

Than, it probably means there's something wrong with your monitor... If you can, test the monitor on another system. If it still displays the lines, you have a hardware problem on your hands!

Sorry! (happened to me too!)

Nope...

That's a reasonable thought(my first thought actually). Unfortunatley, I changed the monitor
and still got the same...

Does the same thing happen when you start in text mode? Try starting linux with this line (in text-mode lilo):
Code:
linux single
It will start you as a single user/recovery shell. If the lines are still visible, I'm not sure what's wrong... If not, then there must be something wrong with your X server...

Keep us posted.
