CentOS 5.2 display settings problem


Hello,

there is a problem after I've installed original ATI driver on my CentOS (5.2 with kernel 2.6.18-128.4.1.el5) machine and temporary disabled secondary screen. Card is ATI X300 GeCube.

Problem is following. On primary monitor there is setting for 1280x1024 resolution. After disabling another screen my primary screen drops to 640x480 resolution and I can not force it to be 1280x1024 pixels on startup in both (KDE and ATI Catalyst) interfaces. This problem persists no matter if secondary display is enabled or not. So, I set it to 1280x1024 pixels but in next session startup it drops to 640x480.

In /etc/X11/xorg.conf I cannot find any specific resolution setting, only some settings obviously set by ATI driver installation. Is there any point to force manually resolution setting in "xorg.conf", would I unnecessary disrupt ATI settings this way ?

Here is listing of /etc/X11/xorg.conf:

Code:
# Xorg configuration created by pyxf86config

Section "ServerLayout"
	Identifier     "Default Layout"
	Screen      0  "aticonfig-Screen[0]-0" 0 0
	InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

	Option	    "XkbLayout" "hr"
EndSection

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

	Identifier   "amdcccle-Monitor[1]-1"
	Option	    "VendorName" "ATI Proprietary Driver"
	Option	    "ModelName" "Generic Autodetecting Monitor"
	Option	    "DPMS" "true"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "radeon"
EndSection

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

	Identifier  "amdcccle-Device[1]-1"
	Driver      "fglrx"
	BusID       "PCI:1:0:0"
	Screen      1
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
	EndSubSection
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

Section "Screen"
	Identifier "amdcccle-Screen[1]-1"
	Device     "amdcccle-Device[1]-1"
	Monitor    "amdcccle-Monitor[1]-1"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
	EndSubSection
EndSection
One more thing, resolution 1280x1024 works fine in login screen, it drops to 640x480 immediately after logging in KDE.

If not in xorg.conf, where is the problem ?

Thanks,

Josip
