installing RedHat 8 problems with ati video and LCD

Hi guys, I'm a real newbie to Linux so don't laugh at my questions :-)

I have installed redhat 8.0 on my computer, after a long night. The comp specs are: PII-400, with a 20Gb HDD, Ram 384Mb, video card: ATI RADEON 8500DV-64Mb, and a 17" F-10 NEOVO LCD display.

Now let me explain the steps what I've done:

1. Boot from RedHAt CD1
2. Choose Graphic mode
3. After probe my LCD was shutdown.? I couldn't see a thing
4. OK reboot and start with option noprobe..same result
5. OK. rebot and started with forced resolution:
"linux resolution=1024x768"...Charming. It's working
6. installing redhat.
7. Redhat detected my video card as ATI RADEON 8500, and my display as F-17. Choose resolution 1024x768x16bRunning through all configuration steps OK
8. Create boot floppy. (I want to boot using a floppy, I don't want to mess around yet with MBR and boot loaders)
9.Finish installation
10. Reboot


the boot process is ok but I got errors in starting in graphical mode. It says that my videocard and display have some errors and cannot start the graphical mode.

How can I reconfigure my video card setting and monitor from console?

Thanks a lot guys

As root, try running Xconfigure or redhat-config-xfree86 in command line. It will walk you through setting up your X server settings (reconfigure your video card and monitor settings). Additionally, make sure you've got all the proper modules for your video card and everything.

Not working.
it says:
"Couldn't start Xserver, trying with a fresh configuration" and after a few seconds

"Error cannot start X Server"

I'm sorry I didn't respond earlier, I lost the post. Anyway, I read your initial post again, and after you stated that reconfiguring X didn't work, you might want to verify that you have the right video module (driver) installed on your system. You can do a search on for your video card make and model (chipset if you have it). There should be something out there to tell which module you need. After you find out what module you need, type the following at command line:


This will give you a list of all your modules you have running on your system. If the correct module is loaded for your video card, we need to investigate further. If not, try typing the following:

modprobe <modulename>

You'd type the above with the correct "modulename" and without the <>'s in there too. If it cannot locate the module, then you'll need to find it online and download it. After you've got it downloaded, you'll need to install it. If you need help with this, let us know and someone who uses RedHat will be able to walk you through it.

If you don't get any errors after running modprobe, you should try starting X again and see if it works. If not, it could be the refresh rates you assigned to your monitor. Check your monitor's documentation or search for it online to get the exact horizontal and vertical refresh frequencies.

If it keeps failing, try to post any errors you find in /var/log/XFree86.0.log and hopefully we'll be able to make heads or tails of it. Hope this helps.
