weird monitor garbage on my new redhat box
I just finished installing red hat on a new machine that someone had left out on the curb to be trashed. I had to stuff an old hard drive, some ram, and an old cdrom in it, but it's a working P2 Celeron 433mhz now.
I'm using my really old AOC monitor on it now that I was using on another linux box.
I don't think I was having this problem before when the monitor was hooked up to my other box, but now I seem to be getting a lot of temporary flashes of garbage on the monitor. This happens both in X and just from the shell.
e.g., if I hold down the return key in the shell, I can see color stuff with random characters flashing at the bottom of the screen as it refreshes. It goes away when an image is still, but it appears to be more than normal.
Do you think I have the horiz & vert refresh rates set improperly? Red hat seemed to auto-detect them as it auto-detected my monitor brand correctly.
This doesn't just happen in X, so I'm not sure where to change the refresh rate.
Oh, also, I should mention that the power supply makes funny high-pitch noises whenever it's plugged in. It's very subtle when the machine is just plugged in but not on, but they become more pronounced whenever the hard drive or cd drive are spinning. But I don't know if this would affect the monitor since the monitor has its own power supply.
Thanks for any advice!
