problem with screen resolution on ubuntu 8.04 guest

Post by brcflip2001 »

I'm running a ubuntu 8.04 guest on windows vista host. Right now it says largest resolution i have is only 800x600. I'd like to do fullscreen which would be 1440x900 for me. I have installed vboxlinux additions on the guest and the mouse is seamless (the windows mouse never goes away though...odd) anyways I can't figure out how to get that full resolution.

Thanks for the help!

Search the forums, it's been discussed here dozens of times. You need to add 'Driver "vboxvideo"' to the 'Device' section.
Read the Forum Posting Guide before opening a topic.
VirtualBox FAQ: Check this before asking questions.

KDE4 is different enough though that the old solutions are not applicable - I'm running Kubuntu w/KDE4, anybody has any suggestions?

Hello,

Same here : Xubuntu 8.04 and a little 800x600 screen on my OSX ;-).

Thanks for us,

Hi this worked for me;

Edited xorg.conf;

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

and

Section "Screen"
Identifier "Default Screen"
Device "VirtualBox graphics card"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "2048x800" "800x600" "640x480"
EndSubSection
EndSection


I edited the "modes" to reflect the resolutions that I needed and voila!

Cheers
Colin.

Thanks it works like a charm here.

PS : ... but after a reboot, the screen comes in 1280x800 : then I need to select my 1280x1024 in the monitor panel :-(

@41south -

The Mode line! After sifting through a half dozen worthless "this has already been discussed" posts and partial responses, someone finally bothers to post an excerpt from their xorg.conf. (My installer automatically added the vboxvideo driver but I was having the same problem.) Thanks for taking the time to help.

I had my xorg.conf file looking like that and it still did not work. I had to reinstall the linux guest additions which i didnt have to do when i updated to 7.04 and 7.10 i just had to reinstall them when updating to 8.04 and now the screen resolutions are being recognized. So if there is anyone out there that edited the xorg.conf file and are still having problems make sure the linux guest additions are installed.
