I've recently installed RedHat 9 on my old Thinkpad 600x and can't get the video out of 800x600 and into 1024x768 mode. Anyone had this problem? Suggestions for fixes?

Please be as detailed as possible as I'm still learning linux.

sorry, opera screwed it up, ignore this post

Does your laptop monitor support 1024x768?
If so, and i'm assuming you're talking about X here, you need to press [alt] + F2 and type redhat-config-xfree86 which brings up a window which will let you change your resolution

Yes, the monitor supporst 1024x768. Looked great under WinXP. When I go and change the resolution in the redhat configurator, it asks me to reboot or restart X. I do so and it's still in 800x600. It has the correct video card detected, but is using "unprobed monitor". Could this be the issue? Thanks a ton!

Hmm, is your machine a 600x or a 900x?
You should go to /etc/X11/XFree86Config and make sure 1024x768 is listed under you video settings.

Another option is to try sending the kernel option vga=0x305 at bootup and see if that helps. (if your using lilo you should type linux vga=0x305 (linux being whatever boot image name you gave it))

Ouch, it is a 600x. I think I was so happy to get the build done (save the video) that I didn't pick it up when I proofread. Still no luck with the video workin' correctly.

Hmm, post your XF86Config here (/etc/X11/XF86Config) there is a sample XF86Config for a 600x here but i don't think it'll work with your distro.

Yes, you need to edit the bit near the bottom where it says

Depth 16
Modes "800x600" "640x480"

to
Depth 16

Then use redhat-config-xfree86 to change your resolution, restart the X server and it should hopefully be fine.

So edited the file as required, set the resolution, rebooted, and it came back as 800x600. I'm positive I edited the file correctly. Am I doing something wrong here?

Well, just checking, did u edit the file as root? Does the file still show the changes? I'm not sure baout with that distro, but I do know with Mandrake 9.1&9.2 RC2 or Redhat 8&9 you can choose "generic laptop display 1024x768" when you're setting it up. However, what's been said about editing the XF86Config should work for you, however, make sure you edit the fiel as root, and that you save it. Even then, re-open the file to make sure the changes took place. I know it might sound stupid to you, but I've done it myself a few times, and occasionally changes just wouldn't take the first time around. You also might want to try editing it from console mode ("init 3" as root). You can get back to X by either saying "startx" or "init 5". Also, as a sde note, if you need to restart the X server, without reboots, ctrl + alt + backspace will do it.

I had this exact problem installing Red Hat 9 on a Dell Inspiron 3500 with a NeoMagic AVI+ card. I edited the XF86config as suggested to add the 1024x768 mode, but it still would set itself to 800x600.

I'm not sure why this fixed the problem, but as soon as I connected a monitor and had the display tool auto probe the monitor, it would then accept 1024x768 setting.

I did do a ctrl crt/lcd force on the keyboard to force the video just to the monitor. When I swtiched back to the LCD screen it worked as well in 1024x768. After disconnecting the monitor and restarting the xserver, it continued to work fine on the LCD.

I think this probably has something to do with the fact that the NeoMagic driver has settings to enable simultaneous internal and external displays.
Hope this helps.
