Xorg.conf dual screen setup problem
Hello all,
Im new here and fairly new to Linux, so apologies in advance. My problem is this, Im trying to set up a dual screen system with 2 identical monitors. However I cannot get screen '1' to be on the left and screen '2' to be on the right. Dragging between the 2 works as expected (so its not a case of physically picking up and moving the screens), and I'm not confident enough about modifying my Xorg.conf file to know whats going on. Heres my Xorg.conf file; Quote:
The last thing which may be helpful to know is the monitors are connected to the same graphics card, but one is a DVI connection (the current left screen and screen 2) and one is a VGA (the right screen and screen 1). Can anybody help me swapping the screen numbers around so the left screen becomes screen 1, and everything happens here (login screen, icons line up, etc...), and help would be much appreciated! Thanks, Lee |
So you use binary proprietary driver from nvidia. I would propose the other one.
On the official X site for nv (http://www.x.org/wiki/nv) you'll find the link to nouveau driver. I succeed with for my laptop. I especially like it for on flight reconfiguration by xrandr. Have a good weekend, enjoy! |
That looks mostly right. You might try
Option "xinerama" "true" or Option "xinerama" "on" instead of: Option "xinerama" "off" as I believe that it's the xinerama that gets you the multi-head / screen layout. Or I could be wrong. Some proprietary drivers have special options, so you might try googling specifically for your driver as well. As the bug forest only likes maple trees, only on thursdays, only after a fresh rain, but only when the moon is half full. (i.e. they were trained by microsoft) |
Hi Andrey@ and Shadow_7,
Thanks for your replies. I cannot change the driver, im on a system maintained by a network admin, and I dont have the privelages. He wants to help solve this problem however, but isnt willing to change the drivers for one machine only. Regards xinerama - im not sure exactly what it does, but when it was enabled, clicking to maximise a screen would maximise across both, whereas I want maximise to maximise across one only. - does that kinda make sense? Thanks again guys, Lee |
Try to change

The easiest way would be to run /usr/bin/nvidia-settings. Click on the "Server Settings" item in the left pane.

Thanks jschiwal,
Ive already tried the graphical interface, but its not working. Unfortunately the administrator has gone home for the weekend now, and so ill have to wait until monday to make any further changes. Ill try the 'rightof' to 'leftof' trick and see if that works, but i think ive already tried that, and its nothing as simple... Do you think that linux has built in recognition for the VGA screen to be screen number 1, and DVI to be number 2? Thanks, Lee |
It might be a good idea to add
BusID "<bus-id>" to each of the "Device" sections. Using a dual head video card, it will be the same. This might help, due to having a separate "Device" section for each "Monitor" even though you only have one device. Code:
/sbin/lspci | grep nVidia |
I have a low tech solution. How about physically swapping the monitors?

Hi jschiwal and Larro,
Ill try adding the BusID to my Xorg.conf file and see if that makes a difference. And as for the low-tech solution Larro, as I said right at the beginning... Quote:
Ill let you all know how it goes... Lee |
Hi Guys,
Just to let you know, the BusID "PCI:1:0:0" crashed my X windowing system, so Ive decided to live with it the way it is. Thanks for your help and support, it is much appreciated. Lee |
