Hi..all..
I was using Redhat-7.3 but i had problems...as such

1.My video card (intel extreme graphics card integrated on intel845GLLY chipset) was not supported and i have selected vesa generic from the list and it worked.the resolution was 1024x768(in 16 bit color depth).

2.My sound card (intel AC 97 ICH4) was not supported.

So recently i upgraded to redhat-8.0.It recognised my video card correctly as intel845.And this card was there in the list of supported cards.after installing i tried to configure X-window.using xf86config command.(Xconfigurator has been removed from redhat-8.0 it seems).So i entered evrything manually.

monitor:
horizontal sync:30-55
vertical syns:50-120
name: S/T/56E/V (something like this)
video card:
Intel 845( selection code 359,this card was there in the list)
video memory:8mb
And i have choosen resolution 1024x768 ( 24bit color depth) as the starting mode of X.And after finishing i started X.then i got a blank terminal
and a floating message:
SYNC OUT OF RANGE

So i tried resolution 800x640( 16 bit color depth) with the other things same.then started X.It started and it worked fine.Now from X ,i started X-display and from there i probed for my monitor and video card.It probed the correct monitor( with same sync ranges as given in the monitor manual) and video card.but i want to increase my resolution.how can i do it??

now a bit of information that might be helpful:

1.I have already set 8 mb of video memory in BIOS.
2.This time selecting vesa generic also doesn't works.
3.Sync ranges are correct.(taken from manual as well they were auto probed).

i have tried redhat-config-xfree86 also.but the moitor keeps blinking for a while and then displays messgas like..

failed to start x..
trying with a fresh configuration
failed to start x would you like to see the log file.

have you tried with <prompt># XFree86 -configure

?

Also, monitors will support different resolutions at different frequencies... so it could be a matter of lining up the right freq w/ the right resolution.

just some random thoughts to give a hand.

no i haven't tried,but how to control frequencies with the resolution.even xf86config command gives me a option to enter the sync ranges only not the frequencies.

You're right, you can specify color depth per resolution but not sync freq. ... hmmm... does 1024x768 at 16 color depth work?

No,the problem is yet there i am not able to get a resolution of 1024x768( 16 bit even).i was getting this resolution at least in redhat-7.3 using vesa generic driver.

gethemant, here's another guy with the same video chipset was having problems with his setup... says here he installed linux kernel 2.4.20 and installed the 4.2.99 XFree rpm and now everything works fine... maybe this can be of help...
