Slow refresh screen problem for Fedora 14.
 
I have been using Windows on my laptop, but recently switch to Fedora 14.
However, there seems to be a screen refresh rate issue that i didn't encounter when using Windows.
The symptom is that when I scroll down through the browser page, the content become gibberish and unreadable. I have to do a refresh to read that content.

I did some searching on the Internet and found that it may be able to fix by updating driver, but i have no idea what and how to do it. can someone suggest a solution? can i use yum?

Yes! you are right, in many cases it's just happen if the system didn't have the right VGA Driver.

So, first you must know what is your VGA Vendor! and then install it using yum: "yum install kmod-nvidia"
This may help you: http://www.mjmwired.net/resources/mj...ra-nvidia.html

Hello ufmale,

when you execute
Code:

lspci -v
as root, you get a more verbose output of the lspci command. In the last line of the section of each device you'll find the module which is actually in use for this device. You may post here which driver this is.

For recent ATI-drivers you may look here: http://support.amd.com/us/gpudownload/Pages/index.aspx

Here is the lspci -v result:

What yum command do i need?

Well, you could try to use the radeonfb module instead the radeon module. There are two ways to do that. First is to leave X, use rmmod to unload radeon, if you get message "driver in use", you'll have to check with lsmod which drivers use radeon and unload them at first. Afterwards you may use
Code:

modprobe radeonfb
in order to load radeonfb.

If this doesn't work, you may blacklist the "radeon" module and reboot the system. Look at the dokumentation of your distribution about blacklisting.

If this doesn't work as well, you'll have to go to the downloadsite of the vendor of your laptop (referring to the downloadsite of AMD/ATI) and look for the driver.

Do not switch to radeonfb and do not try to install any driver from AMD. That advice is just.. well... bad. Your GPU has not been supported by the drivers from AMD for about two years. radeonfb is only a console framebuffer driver and will just break direct rendering if you have it working already... If not, it will keep you from getting it working.

Please attach your /var/log/Xorg.0.log file to a post here.
