The following is a format corrected of the message i posted yesterday:

>>.................start

I'm trying to configure my Xserver to get working as th dual head mode on my laptop.
it's a 1280x800 flat screen and the extra monitor is a 1440x900.
the specific config lines are as follows:
Section "Monitor"   
 Identifier  "My Monitor"   
 HorizSync   30-48
VertRefresh    60
EndSection

Section "Monitor"
Identifier    "Extra Mon"    
HorizSync     31.5-67.5    
VertRefresh   75
EndSection
Section"Screen"    
Identifier  "Screen 1"    
Device      "** ATI Radeon (generic)               [radeon]"   
 Monitor     "My Monitor"    
DefaultDepth 24        
Subsection "Display"                
Depth           24                Modes           "1280x800" "800x600"                
ViewPort        0 0
EndSubsection
EndSection
Section "Screen"
Identifier    "Screen 2"
Device        "** ATI Radeon (generic)               [radeon]"
Monitor       "Extra Mon"
DefaultDepth  24         
Subsection "Display"         
Depth          24         
Modes          "1440x900"
 ViewPort 0 0        
 EndSubsection
EndSection
Section "ServerLayout"
Identifier  "Simple Layout"
Screen "Screen 1"
Screen "Screen 2" LeftOf "Screen1"
...EndSection

but it doesn't work as expected, the extra monitor display seems to be assigned a 600x800 resolution and shows a part of the desktop but can slip on the whole desktop when the pointer reaches an end of the screen. While the main screen of the laptop is assigned the correct resolution.

the output of the Xorg.log is as follows:
(==) Log file: "/var/log/Xorg.0.log", 
Time: Sun Dec 23 13:18:44 2007
(==) Using config file: "/etc/X11/xorg.conf"
(==) ServerLayout "Simple Layout"(**) |-->Screen "Screen 1" (0)
(**) |   |-->Monitor "My Monitor"
(**) |   |-->Device "** ATI Radeon (generic)               [radeon]"
(**) |-->Screen "Screen 2" (1)
(**) |   |-->Monitor "Extra Mon"
(**) |   |-->Device "** ATI Radeon (generic)               [radeon]"
(EE) Screen Screen1 doesn't exist: deleting placement

While when the xorg.conf file is configured for a single head everything is OK.

by the way i would like to know if this is normal tthat drm is never loaded.

when i load it manually it says:

root at slack12:/home/slackkk# modprobe drm
FATAL: Error inserting drm (/lib/modules/2.6.21.5-smp/kernel/drivers/char/drm/drm.ko): Cannot allocate memory



but the X interface works well, Open GL screen savers are Ok, some are slow.
google earth is not hard accelerated at all, it is awfully slow and runs th CPU at 100%
