Hi
When i run dmesg | grep VGA I get this error message.
fb0: VESA VGA frame buffer device
fb: conflicting fb hw usage radeondrmfb vs VESA VGA - removing generic driver
I'm trying to figure out why my KDE desktop runs so painfully slow.
My graphic card is
root /home/catch # lspci | grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc RV570 [Radeon X1950 Pro]
Direct rendering is on
root /home/catch # glxinfo | grep direct
direct rendering: Yes

I have tried to deactivate window animations and fanzy pants effects, but it doesn't help.
Even when I right click on the desktop the CPU jumps up to about 70% and there is a 300 miliseconds delay before the menu pops up.

What graphics driver do you have? If you use vesa, it will be a lot slower then if you had the driver for your video card. After doing some research on your card, it seems fast enough to run KDE.

I use the radeon driver (xf86-video-ati)
Starting to think the problem has to do with my CPU (AMD athlon 64 3500+)
When I scroll in my terminal it is like my grandma trying to dial on a iPhone. (amazing lag)
Have been googling for som time now, but it is hard when I can't identify the problem.

Do you use vga=XXX in menu.lst ?

Do you use vga=XXX in menu.lst ?
Yes. I use VGA=794

If you are on kernel 2.6.33, then you have to remove the vga thing because it conflicts with KMS. Read on this article for more info.

As "schen" says, framebuffer options cause problems with KMS.

Thank you guys!
By removing the vga= line in menu.lst solved the first error.
But still KDE runs slow. I do belive my computer has a lot more potential then I am experiencing with KDE.

KMS could be a problem. You could disable it. Read the wiki for the "how to".

Also, can you run any other DE/WM fine?
