Hi.
Every now and then i boot into my Ubuntu partition, and then 5mins later, i reboot and go back to Vista.
Reason?
It wont detect my second monitor, and wont display either at 1920x1200.

The current install is the one prior to 8.04, upgraded.
My final shot at getting at least the proper res on one is a fresh install...?


Anyone got any tips?
 
is your graphics card ATI or nvidia?

If you have ATI then im not too sure how it'll work out, i experienced problems with my old graphics card and dual screens in linux, if you have a nvidia card then the graphics drivers are pretty good at setting up dual screens

If you're using an nvidia graphics card then run in the terminal

Code: 
sudo nvidia-settings

Click on 'X Server Display Configuration' and everything can be configured fairly easily from there.
 
Then you will need to hand configure your x conf, should be /etc/X11/xorg.conf

Forget being able to have a single 'stretched' desktop like on windows, you'll only be able to manage two different desktops and only be able to move mouse/keyboard between the two - not applications.

ATi on linux is a waste of time to be honest, nVidia is ok for dual screens on the same card but useless over multiple cards.

It still has a long way to go for those very reasons, i have moved back to windows, i use 4 monitors over two cards and i want a single extended desktop over them all, linux simply cannot offer that.
 
I had a matrox (dont laugh) and had it display one big desktop over two monitors. it was great, dunno about any others just not tried them/dont have enough monitors
 
So basically then, with 2 ATI video cards, wanting dual screens and both at their full res, im knackered? :(.
 
Pretty much, yeah.

You'll be able to have dual screens, and fixing the res isn't too much of a problem but you can't have a single 'extended' type desktop which you'd get in windows.

You will need to manually edit the xorg.conf for adding the resolution you require.

Not even using Xinerama?
 
Xinerama is how I did it I could have sworn. it CAN be done otherwise I wouldnt waste time posting. I could open a console move it from monitor A to monitor B

Does this work in Xubuntu also?

As long as you have the closed-source nvidia driver installed it will work, regardless of the distro/DE.

As for doing it with ATI xinerama should be able handle dual monitors, I've never used it though. The resolution you want probably can be set in the xorg.conf as well.

Actually I missed it earlier, but nvidia aint useless over multiple screens - using the binary drivers and the Twinview option, allows full hardware acceleration over a stretced desktop, windows style. I beleive xinerama will only do it on the main screen.
