Hello everybody
I have a major problem with the configuration of Xorg about the radeon driver and the dual monitor desktop concept.
I use a Fujitsu-Siemens laptop which has an ATI IGP 320M graphics adapter.
The driver consists not to operate the displays simultaneously (the LCD panel and the external CRT monitor)
The error is always:
Code:
(WW) RADEON(0): Failed to detect secondary monitor, MergedFB/Clone mode disabled
My xorg.conf is the following
Code:
###LCD#####
Section "Monitor"
Identifier "Monitor0"
Option "DPMS"
HorizSync 30-60
EndSection
###CRT####
Section "Monitor"
Identifier "Monitor1"
Option "DPMS"
HorizSync 30-60
EndSection
Section "Device"
Identifier "Card0"
Driver "radeon"
BusID "PCI:1:5:0"
Option "MonitorLayout" "LVDS,CRT"
Screen 0
EndSection
Section "Device"
Identifier "Card1"
Driver "radeon"
BusID "PCI:1:5:0"
Option "MonitorLayout" "CRT,LVDS"
Screen 1
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection
EndSection
Section "Screen"
Identifier "Screen1"
Device "Card1"
Monitor "Monitor1"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection
EndSection
Section "ServerFlags"
Option "Xinerama"
EndSection
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0"
Screen 1 "Screen1" RightOf "Screen0"
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
Option "Xinerama" "on"
EndSection
Also the driver recognizes the devices as following
Code:
(II) RADEON(0): Primary:
Monitor -- LVDS
Connector -- DVI-I
DAC Type -- TVDAC/ExtDAC
TMDS Type -- NONE
DDC Type -- NONE
(II) RADEON(0): Secondary:
Monitor -- CRT
Connector -- VGA
DAC Type -- Primary
TMDS Type -- NONE
DDC Type -- VGA_DDC
Is the above correct? I believe the DAC types should be different.
If I change the order of LVDS and CRT in xorg.conf then the CRT monitor works but not the LCD one.
I tried to change the Screen sections using the same device but the error is the same.
Is something incorrect about the .conf? Or something else is going on?
Thanks in advance
