Under Jaunty, I had no trouble using xrandr to power a second monitor, next to my laptop monitor, which I used for giving presentations. I started it with this command:
and my xorg.conf consisted of this:
In Karmic, the same xrandr command is doing nothing. I've tried fiddling with xorg.conf, removing and adding the "Device" and "Monitor" sections. At the moment it looks like this:
If I just type xrandr with the second monitor plugged in, it reports seeing the monitor, showing the usual list of available resolutions and refresh rates. KRandRtray will let me mirror the contents of my monitor just fine, but I've never been able to get side-by-side monitors using that (has anyone?).
So does anybody have any suggestions for what I'm doing wrong? I'm guessing it's something to do with my xorg.conf - is that right? I start teaching again soon so getting this working is a priority!
UPDATE: I've just had a look in System Settings > Display. Even if I activate my second monitor from here, so that it is mirroring my first (just like with KRandRTray), the 'Multiple Monitors' section continues to say "This section is only for configuring systems with a single desktop spread across multiple monitors. You do not appear to have this configuration". I know! I want it!
UPDATE 2: Solved it! Rather than delete this message I thought I'd provide the solution here in case anyone else needs it. In Karmic, X has changed its default names. They used to be VGA and LVDS but now they are, by default, VGA1 and LVDS1. Using those in the xrandr command solved everything. Phew!
Code:
xrandr --output VGA --auto --right-of LVDS
Code:
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Virtual 2800 1024
EndSubSection
EndSection
Section "Device"
Identifier "Configured Video Device"
Option "AccelMethod" "uxa"
EndSection
Code:
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Device"
Identifier "Configured Video Device"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Virtual 2800 1024
EndSubSection
EndSection
