Hello,
I am having problems with video in X. I get an over frequency issue using the stock CentOS 4.2 driver. I have searched IBM and Intel for the driver but no luck. Occassionally I see something about need to load a kernel module for agpgart. How do I do this? Anyone have a similar setup or know where I can find the driver?
TIA

can't you just boot (or switch to) to runlevel 3 and simply run 'system-config-display --reconfig' and get a suitable xorg.conf resolution?

I'll give that a try. I did do system-config-display but without the --reconfig.
Thanks

---- there's a lot of options in the configuration panels...you might find one more suitable if you keep poking around. It helps if the system 'knows' your monitor.

Its fixed. I was poking 'round in the bios and allocated more memory to the card.
Thanks!!

The issue is really the Intel onboard video hardware [which IBM Netvista have with the 845 chipset, and older HP units have at the 810 and 815 chipsets; newer Dell kit have 9xx series onboard video], which is at best moderately well supported
The bugs which Mike Harris upstream has had on Intel kit, and his discussions on the devel mailing lists, show much that Intel could do better. ;) It turns out the Intel video hardware bios cannot be persistently have mode settings reprogrammed - one has to do it on the fly at boot time before X starts running.
The doco on the xorg.conf file could be better, but one can plow through it and find some help with our friend Google.
I had to use a program called '915resolution' from http://www.geocities.com/stomljen/ to remap video bios in ram, to support my (Westinghouse) panel monitor at 1440 x 1050 ($420 on sale at Best Buy last week - highly recommended). These is a similar tool for the Intex 8xx onboard video hardware.
I added an item to the R/L 5 initscripts, to run this in /etc/rc.d/rc5.d/ as S89videotweak, [right before the xfs starts up]:
#!/bin/sh # set up the Intel 865 chip for our Westinghouse monitor /etc/rc.d/915resolution 4d 1440 1050 16 /etc/rc.d/915resolution 41 1152 864 16 /etc/rc.d/915resolution 43 1280 960 16 #

Hello Russ!
About 99% of this is way over my head. :-(
I agree, Intel should do better for the Linux community. The only updated driver I found was for the 915 chipset.
I ended up allocating more memory in the bios and got much better results. I don't use X that much as this is my server. At least now its useable when needed.
Thanks!!!!
