I have two monitors
Dell 20" which has a max res of 1680x1050 (widescreen)
NEC 17" which has a max res of 1280x1024 (not widescreen)
I would like to use both my monitors for my setup. I read a ton of information from just about everywhere, but I have one small problem. Here's the stuff that I referred to

Simply connecting the two monitors defaulted to 1280x1024 resolution which was the max supported by the smaller monitor.
Here's my xrandr -q output

I had to create an xorg.conf file (since I am using HAL) and was not using xorg.conf file until now. Here's my xorg.conf file

By adding that into xorg.conf, I was able to get the correct resolutions on both my monitors. However, they are both cloned. I was hoping I could use my 17" as an "extended desktop" (to use the windows terminology) and be able to transfer/move application windows to it. How would I go about doing that?
I am using musca so I guess transfer/moving would be more like having a new group on my second monitor. I am using xf86-video-ati drivers currently, but I can switch to something else if I have to.
Can someone help?
EDIT : I also tried changing the Virtual line in xorg.conf to
Virtual 2960 1050
because 1680+1280 = 2960, but that doesn't seem to change anything. :-(

this is what i use
xrandr --output DFP2 --auto --right-of DFP4

Using that type of a command gives me one massive screen and since I use a tiling WM, that's pretty much useless to me. I need to be able to move windows around to the second monitor while being able to have different applications running in monitor 1

oh.. in openbox that command does what you're describing, if i understand you correctly.
never tried musca but maybe there's some settings to fix it for you

It seems that the problem is with musca then. The command in xmonad also does what you want. Does musca support xrandr in the way you want?

From what I have read, it does. Maybe I am missing a setting somewhere. I will try browsing the musca thread and see if anyone else has encountered the same issue.

Hi Inxsible,
I got your message about needing help. Sadly, I don't use Arch Linux anymore or Musca. Sorry

it's easy to do this under nv card

Thanks but I have since given up on using a dual monitor setup for musca. I use i3 solely which does what I want.
I didn't mark the thread as solved, frankly because it still doesn't work in musca.
