Full Version: Redhat9 And Resolution
Linuxhelp > Support > Technical Support
I just got this new Samsung SyncMaster 192N and it's amazing. I also built a new athlon box but the video card is the only thing relevent.

It's an SiS300 chipset. I did the text installation of RedHat9.0. A basic workstation installation. Everything runs great until it's done installing and it reboots. It goes through the normal startup process, but once it's about to run X, the monitor cuts to "Out of range" and thats it.

I know the video card and monitor support 1280x1024, but to double check I did an install and set the resolution to 1024x768. Still the same problem.

So I booted to console and ran redhat-config-xfree86. The program attempts to load, and then dies with the error:

Couldn't start X server, trying with a fresh configuration
Trying with card: VESA driver (generic)
Error, cannot start X server

Could I be getting these problems because I don't have the right driver installed for the card? When I did the first installation the only driver for SiS that I could find that came close to SiS300 was SiS305, but even that didn't work.

Please help, I'm stumped.

Looking at the page for the sis drive says it will work with SIS 300.

The samsung page says the monitor has the following frequency ranges:

30-81 KHz horizontal
56-85 vertical

So edit the file:

/etc/X11/XF86Config ...

Find the line:

Driver "vesa"

in the vieo card Section "Device" and change it to

Driver "sis"

and find the lines


in the Section "Monitor" and change them to

HorizSync 30.0 - 81.0
VertRefresh 56.0 - 85.0

Then you should be able to boot.....
Section "Monitor"
Identifier "Monitor0"
VendorName "Samsung"
DisplaySize 380 310
HorizSync 30.0 - 81.0
VertSync 56.0 - 85.0
Option "dpms"

Section "Device"
Identifier "Videocard0"
Driver "sis"
VendorName "SIS"
BoardName "sis"

Ok, I changed it to what you said and still no luck. Any ideas? I'm still lost as to why this isn't working.

I got it. smile.gif

Thanks for your help.
