New vidcard, Sapphire Radeon 1650 no display on Fedora 6
 

I am pretty new to Linux and have recently installed a new video card, a Radeon 1650 512mb clone. The display will not work on Fedora Core 6.

You need to do this from the command line:

su -
root password
vi nano /etc/X11/xorg.conf

Then locate the "device" section, look for driver and replace whatever is there (probably ati) with "vesa".
You may also want to check under "monitor" whether the HorizSync and VertRefresh are not too high for your monitor (you should check these values in you manual or using google).

After that, reboot.

You now have a generic driver. It works but it's not the best quality. Set up the livna repository and install the flgrx driver.
