Question Can't set the resolution of Gateway 200XL


I am running Redhat 9.0 on my Gateway 200XL.

I have tried to set the resolution to 1024x768 via redhat-config-xfree86, but it doesn't work. After I reboot, it is still 800x600.

I have tried to manually edit /etc/X11/XF86Config and put "1024x768" in front of "800x600". It still doesn't work.

Any idea?

Here is the ONLY screen section in the XF86Config

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

I don't know whether it is a problem with the video card driver, Redhat automatically detects that the video card driver is i810 with 16MB memory. However, indeed, it only has 8MB memory (based on the information in the bios).

If you have files /etc/X11/XF86Config and /etc/X11/XF86Config-4, any edits you make to XF86Config will be ignored because XF86Config-4 is always chosen first. Make sure that changes are made to XF86Config-4, and make sure to back it up if you change something. Under "device" section, you can set video ram to 8 instead of 16 MB.

There is no XF86Config-4, only XF86Config and its backup XF86Config.backup

So any suggestion?

When you run the RedHat program to set up the display, do you choose "Generic Laptop 1024x768" (or something similar)? Or did you try to set your own refresh rate? I would suggest trying to pick a "generic" laptop or LCD at 1024x768. The RedHat configuration program should work. Something you might want to try is selecting the generic VESA driver instead of i810 and see if that works.

The other option is to run the "xf86config" setup program. A step-by-step walk through of that program is here: http://www.bitbenderforums.com/vb22/...?postid=313121 It is for Slackware, but the same thing should work in RedHat. When it asks you for refresh rate, choose 31.5-57 for hsync and 50-70 for vsync. When it asks for video card driver, you can try i810 and if that doesn't work, you can try the generic VESA driver. Set the video ram, resolutions, and default color depth as described in the link above.

Make sure you back up XF86Config before doing anything!

If your display is totally messed up after changing things and you can't see anything on screen: ctrl+alt+F1 will bring you to a text prompt in runlevel 1, you can then go back to where you were before changing anything with "mv /etc/X11/XF86Config.backup /etc/X11/XF86Config" After that, go back to the graphical display with ctrl+alt+F5 or ctrl+alt+F7 (I forget if it is runlevel 5 or 7), then restart Xfree86 with ctrl+alt+backspace.

When I installed Redhat 9.0, it only allowed me to choose either 800x600 or 640x480. There was no 1024x768.

After I chose VESA driver, it works~!

Thanks alot dude.

I wonder why i810 doesn't work.....any idea?

My laptop is using Intel Graphics Extreme 2, and I thought that its driver was i810....
