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


Whilewhen 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@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%
