High resolution = virtual desktop. It shouldn't... [SOLVED]

In my previous XP installation, I've had the resolution sitting comfortably at 1024x768. However, when I set Xorg to those settings, it goes offscreen and into a virtual desktop. How can I make it stay on the screen and make everything look pretty and small rather than simply expanding the size of the screen?

This is on my laptop which I just installed Arch on. On my desktop I could use hwd -x to configure it, but it wouldn't work on the laptop (just sat there, left the cursor blinking away at me... didn't actually do anything) so I used xorgconfig instead. It works fine apart from this issue.

Can you post your /etc/X11/xorg.conf?

Re: High resolution = virtual desktop. It shouldn't... [SOLVED]

AFAIK xorg uses the first mode of your default depth by default, which is 800x600 in your config.
Try switching modes with 'ctrl'-'alt'-'+'
If it works you have to interchange the modes of your default depth in your xorg.conf.

Re: High resolution = virtual desktop. It shouldn't... [SOLVED]

Thankyou! I'd seen this suggestion elsewhere, but wasn't entirely sure what exactly it did, and on the laptop, hitting the shift key to get to the '+' (as there is no numpad) didn't seem to work. However, I forgot about the function key... how embarrassing. Anyway, thanks to everyone for the help. Very much appreciated.

Re: High resolution = virtual desktop. It shouldn't... [SOLVED]

iirc, I believe that on the 'modes" lines in the xorg.conf, in most cases it will default the desktop size (actually pixel width and height of screen) to the first declared resolution.

For instance:
modes "800x600" "1024x768"

Would begin at 800x600 resolution and being able to see the whole desktop when you start X, but if you were to hit ctrl+alt+plus it would then still stay at 800x600 resolution but your virtual desktop would be increased to 1024x768.

So I believe it's generally better to declare resolution setting, for what you want the screen to actually display at, as the first setting if you don't want a desktop size different than your resolution.  (e.g. set it as  'modes "1024x768" "800x600"')

I see that following the earlier advice of setting your default depth seemed to fix the issue for you, but I wanted to bring this up in case you have any more issues with virtual desktop.  I've noticed that it's pretty easy to end up with an undesired virtual desktop if setting aren't just right in some cases.  X seems to be finnicky about having certain settings otherwise it tried to guess for the user which isn't always the desired results.

and you can set your default res with xrandr -s NUMBER
