Screen resolution in Virtualbox cannot be higher than 800 x 600

[Per Kongstad]

Running Virtualbox 2.02 on host 64 bit 8.04.

Installed 8.10 2.6.27-7-generic with enabled graphic driver under Hardware Drivers will only allow for 800x600 or lowere resolution.

Tested with guest-addition from Virtualbox with same result.

Tried to resett using xfix to no avail.

Menuoption in Virtualbox session 'Auto-resize Guest Display' is greyed out and not active.

Thanks for reporting. I believe this is an upstream bug with virtualbox. I think there is a bug report up there as well. I have run into this before and think the problem is that x or the guest additions do not specify the virtualbox graphics driver. Try this.

1)edit xorg.conf with nano or another text editor

'sudo nano /etc/X11/xorg.conf'

2)go down to the section "Device" and add Driver "vboxvideo" so it looks like this

Section "Device"
        Identifier "Configured Video Device"
        Driver "vboxvideo"
EndSection

3) restart the virtualbox guest machine

This should allow the resolution to be high and allow the autoresize feature of the guest additions.
you can also look at this discussion of the issue http://ubuntuforums.org/showthread.php?t=926408

I am going to close the bug, however if you problem is not fixed please reopen it. And attempt to explain where I misread the bug.

good luck

Hi,

Adding Driver "vboxvideo" fixes the issue for 8.10 beta.

Section "Device"
        Identifier "Configured Video Device"
        Driver "vboxvideo"
EndSection

But the funny thing is that i have 8.04 and 8.10 Alpha versions which worked as supposed to.

So I'm not convinced that it is not a bug in Intrepid.

But I run the Ubuntu LiveCD from the virtual machine.
So I cant change the xorg.conf file.
It should autodetect virtualbox.
