'Juddery' application windows after a new linux installation

[ianmb]

I'm having a problem with application windows 'stuttering' when dragging them across the screen, they do not move as smoothly as they should after a new O/S installation.

I'm running the latest kernel 2.6.9-89.0.29.ELsmp on RHEL4, Update 8. My monitor is a 22" Iiyama ProLite B2206WS monitor and Radeon HD 4350 graphics card.

I've downloaded and installed the latest linux drivers (fglrx 6.8.0-8.771-1) from the ATI website. I removed the default xorg.conf file and run aticonfig --initial. I also tried both the DVI and D-SUB connections, but the 'juddering' problem still remains.

I've tried setting the V and H sync rates manually using aticonfig, and some other changes in the xorg.conf file but that just causes a kernel panic on reboot!

This is the default xorg.conf file generated by aticonfig:

Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Module"
EndSection

Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection

Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:1:0:0"
EndSection

Section "Screen"
Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
Monitor "aticonfig-Monitor[0]-0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

I'd appreciate any advice!

2.6.9 kernel is very old compared to your ATI card. There are certain options that have to be enabled in kernel to support this kind of card, and DRI support has to be turned off because this functionality is provided by ATI driver. Also, there are supporting Xorg libraries that probably are too old for this driver. Xorg server itself has to be at least 1.7, I think.

Problem solved. Instead of selecting:

Generate Distribution Specific Driver Package (i.e. an RPM)

I selected 'Install driver 8.771 on X Org 6.8.x' and all worked great after a reboot.
