screen res

Post by glenc »

Hi, at the moment I can only get the host OS (Ubuntu 11.04) to run at 1024x768
The host system (Win7 pro 64) is running at 1440x900 on a ViewSonic VA1903wb 19" wide screen monitor.

In the guest OS Under system>preferences>monitors: 1024x768 (4:3) is the best Ive got. The monitor is shown as "unknown" is this a driver issue?
Should the guest OS be able to run at 1440x900? or is it limited?

In the settings I've given 128MB to the display as well as 2 monitors, as I have 2 the same.

Any help appreciated!

Thanks

Make sure that you are using version 4.0.8 of VirtualBox and install the guest additions (in the guest).

If you are sure the guest additions are installed properly then look at the top of the window and click on view and make sure that the auto-resize has a check mark or use the host+G toggle in case your version does not have view (I am working in my dev version at the moment and it does not always follow the regular version).

Interesting, its now 1440x900 :)
Ive made a backup of xorg.conf now in case I break it again, it should hopefully just be a matter of over writing the old one.
As a matter of interest, the Nvidia-configurator I think its called is what messed it up the first time.

Ah, yes, the nVidia driver and config tool that gets installed by default. You can remove such drivers, they aren't needed. The way you hosed up your system with that, is that the application created an xorg.conf with the driver nvidia statement. If you dropped to a TTY using Host+F2, then you could move the file and restart the Guest to fix it. You can also use a Live CD to mount the hard drive in there and edit files on it if you don't like the command line.
