X Display problem
 

I set up Redhat 8.0 on my father's computer, and I can boot up and login fine with X, but it leaves blotches of graphics randomly on the display. I'm sure I need to edit something in XF86Config, but I wasn't sure if this is a problem with his monitor or his video card. Here are the specs:

Video Card:
Intel 845 PCI Accelerated SVGA
Driver = i810
VideoRam= 16384

Monitor:
Avitron AV-7TF
800x600 @ 16 bit
Horizontal Refresh Rate = 30.0 -70.0 (kHZ)
Vertical Refresh Rate = 50.0 - 160.0 (HZ)
DPI = 68 by 66

Those are the defaults detected by Redhat. It does indeed have that video card and that monitor. It's just annoying. If a dialog appears, after I close it, part of it will still be on the screen. Thanks for any help. By the way, I had a difficult time searching for this because I didn't really no what to call it. So I apologize if this is has been posted several times.

What is Driver i810 ? In your XF86Config-4 in Section "Device" is there something like: Driver "vesa" ? What Kernel Version are you using?

The computer is running kernel 2.4.18. Driver "i810" is the driver that the database in xf86config says corresponds to the Intel 845. In the /etc/X11/XF86Config there is a section "Device" and for Driver it says "i810". there wasn't an XF86Config-4 section - just the one I mentioned above. Like I said earlier, it works but it's just a pain having blotches of graphics on the screen. Thanks for your help.

OK, i know your problem! By the way, the new versions of XFree86 use the XF86Config-4 Config File. The earlier (under version 4.*) the XF86Config. Choose the one you are using and try instead of i810 "vesa". I hope it helps.
