Post subject:  Ubuntu screen resolution in VirtualBox
Having found that dual-booting with Ubuntu was too much of a pain in the southbridge, I decided to use the easier method of a VM. I gave it 770MB of RAM just for the sake of it, and 40MB of video memory. I think that this is more than necessary. After installing everything went fine. It works well and does everything I want it to.

However, the screen reolution is 800x600. Going into Preferences/Monitors gives me the alternative of, wait for it, 640x480!

Having an ATI HD2600, I installed the fglrx grivers. No change. I installed Catalyst Control Centre. No alternatives appeared, but when I try and load up CCC, it gives me

Initialisation Error wrote:
There was a problem initialising Catalyst Control Centre Linux edition. It could be caused by the following.

No ATI graphics driver is installed, or the ATI driver is not functioning properly.
Please install the ATI driver appropriate for you ATI hardware, or configure using aticonfig.


So off I went into aticonfig.
Code:
sudo aticonfig --initial

tells me "No supported adapters detected." Is this something to do with the fact it's in a VM?

Am I barking up the wrong tree? Google tells me to modify Xorg.conf, which does not exist in the specified folder. How do I set the resoution to 1024x768 or preferrably 1200x800?

You might start with giving it a little more video memory? Have you tried shunting up to 128mb?

I could be wrong, but I think I read somewhere that Xorg.conf was no more? I could be wrong on that case though...

it would be best to give the GPU 128MB and the system 2GB of usable memory in VM
also check in the system menu (driver updates) for drivers as that will install the required drivers auto ...

Right, I've given it the maximum 1.5GB RAM and 128MB video, unfortunately no change. Re-installed the drivers, but System-> Administration-> Hardware drivers says "there are no proprietary drivers in use."

Grr. I'll post here again if I find a solution.

Post subject:  Re: Ubuntu screen resolution in VirtualBox - Sort of Solved
Right!

I eventually "figured out" how to get somewhere...

After further searching, I set the CD/DVD device to VBoxAdditions.iso, and tried to run the "VBoxAdditions-x86.run" file with administrator privileges in the command line. This did not work for some reason.

I then double-clicked on the "autorun.sh" file instead, and after the admin password it installed everything, after which point there were precisely no new resolution options...

I rebooted, and it has now automatically set itself to 1024x768, with options of 800x600 and 640x480.

So, successful, sort of!
