View Full Version : [kubuntu] [64bit] Having trouble configuring for multiple monitors

May 12th, 2010, 09:02 AM
I have two monitors of different resolutions. Under settings->display the settings for my monitor look like this:


Ultimately what I want is to set up this kind of configuration:


But whenever I do, it doesn't work out. When I up after setting the above settings, my configuration ends up like this:


Any attempt to change the resolution or to change the display type to anything other then clone is simply ignored. If I disable the second monitor I can set my first to the proper resolution. If I try to set the settings to what I want they will stick but the second monitor doesn't actually turn on, and if i try to drag windows that direction it acts like a single display.

I have tried using the ATI control panel to adjust my display, but there seems to be a problem entering it as an administrator.I can load the CCC just fine as a regular user, but when I try as an admin a terminal pops up, I type in my password, and nothing happens.

I want to avoid trying to reinstall my display drivers or do anything drastic. In previous versions of linux I would just nano the Xorg.conf file and be done with it, but it seems ubuntu 10.04 LTS doesn't use Xorg, or at least not a Xorg.conf I am used to. I want to set the monitors at their native res and as independent displays, similar to what twin view did for me not to long ago. Can anybody help me?

You may want to try arandr from the repositories. I never had much luck with the included monitor configuration tool either.

If memory serves, I read on the mailing lists that a new plasmoid is in the works. So while the current tool may get minor bugfixes, I imagine that developer effort is placed in the new plasmoid instead.

If you're familiar with the terminal, the xrandr tool is also pretty straight-forward. But arandr is plenty powerful.

$ xrandr --output CRT1 --mode 1280x1024 --rate CRTREFRESHRATEHERE --right-of DFP1

I had the exact same issues as the first poster, but it later fixed itself. :confused:

I'll give arandr a look.
