Need help setting up second CRT for dual screen on my laptop
Hey guys, I'm running SUSE 10.1 and the laptop has a ATI Rage Mobility card. I have the CRT monitor hooked up to the VGA out on the back of the noteboot.
I opened up /etc/X11/xorg.conf and followed a few tutorials for adding a second monitor and enabling an extended desktop.
The problem is that linux keeps giving me errors about how Device[0] and Device[1] cannot share the same adapter, which makes no sense what so ever.
Does anyone have any ideas or working config for such a setup? It seems like the device portion is the problem.
They have the same Bus ID (because its the same card), is that correct setup ?
If you are running the ati official drivers (fglrx), ati provide aticonfig to allow this kind of thing to be done (I did it myself before the CRT packed up).
I havent actually got the ati drivers installed at the moment, but I think that running the command:
Code:
aticonfig --help
should shed some light on how this can be done.

This may be caused by the fact that on some laptops, you cannot run dual monitors as both monitor outputs (LCD and CRT) are the same. Sorry if this sounds confusing but both monitors will basically display the same thing.
I've had similar problems when setting up my external monitor. Quite frankly I still have an issue concerning VESA standard modelines which are not recognized by my CRT (see my post in this Linux Desktop forum), but at least it's working with suboptimal resolution...
Without seeing your xorg.conf and Xorg.0.log I can only guess your problem, but maybe it is of help for you:
- First thing to do is to update your driver if necessary. When in doubt I usually consult the handy "hwinfo" tool (just type hwinfo in your terminal window). Should it not work, first try as root. Should it still not work you have problably to install it. This tool gives you plenty information about detailed hardware configuration, drivers and so on.
- Second I have configured the same graphics device twice with a different name in xorg.conf but the same bus id:
Section "Device"
Identifier "intel internal"
Driver "i810"
Screen 0
BusID "PCI:0:2:0"
Option "DevicePresence" "true"
Option "MonitorLayout" "CRT,LFP"
EndSection
Using these settings I could handle my problems... maybe it works for you, too. Should you still have problems, analysing your Xorg.0.log file is usually quite helpful!
