ubuntu 7.10 guest - display only 800x600

Post by aibkwik »

Platform specifics:

I am running virtualbox on a Thinkpad T43p laptop as the host with Ubuntu 7.10 Gutsy as the guest.
I installed the guestAdditions for Linux.
When I was creating the VM I selected Linux 2.6 as the type of guest OS.

Problem:

I'm using the "Screen and Graphics" Preferences from the administrative menus to try and select the best graphics mode but nothing seems to work. The only display that works is the "Generic" "Plug 'n' Play" which supports only 800x600 and 640x480. Both are lame.

My laptop display is ATI Mobility FireGL V3200 and support 1600x1200.

Can I hope to see ubuntu in a 1600x1200 window?

Thanks for any help you can provide.

Problem solved

This forum entry hit the spot.
The key seemed to lie in setting the vbox guest window to be in full-screen mode when actually performing the config operations and during reboot and login....

read on, my brother.

HELLO
First you must install VirtualBox guest addition then you simply need to edit this file :
sudo gedit /etc/X11/xorg.conf
Then you make something equivalent to this :
Section "InputDevice"
Identifier "Configured Mouse"
Driver "vboxmouse" <-- this important for Ubuntu 8.04
Option "CorePointer"
EndSection

Section "Device"
Identifier "Configured Video Device"
Driver "vboxvideo" <-- this is important for Ubuntu 8.04
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
SubSection "Display"
Modes "1280x1024" "1024x768" "800x600" "640x480" <-- add the resolution you want
EndSubSection
EndSection

Then save and exit.
Then go in system/preference/screen resolution and select the good one.
That's all.

Have a nice day

I had the same problem you need to enable restricted drivers (if yours is supported).In my case my box had nvidia driver and i enable it from settings. Ubuntu doesn't enable it by default i guess due to legal issues .
