Screen resolution problems with openSUSE 11.1

[rrpalma]

Hello,

New to the forum, but have been using VirtualBox for the past year, on Mac OS X and Linux, both as hosts.

Now I need to setup a 32 bit OpenSUSE 11.1 VM as a guest to OpenSUSE 11.1 64 bit (need to run some 32 bit only SW that will not run on 64 bits). VB version is 3.0.6; PC is 2-socket Opteron with 8 GB RAM, nvidia GTX 280 card and 23 in monitor.

VM is configured to have 4 GB RAM; 128 MB assigned to video.

During the 32 bit guest openSUSE installation, resolution is set to 1024x768, and color depth to 24 bit. This will not work -- X wil not start. It seems only 800x 600 is supported. Any ideas?

Thanks!

Code: Select all

sudo zypper install gcc make automake autoconf kernel-source

Then install guest additions and set the Vram to 64 Meg

Thanks for reading, perryg.

I had already tried 2 of those suggestions: all development tools are installed on the guest, and also the guest additions. With that done, I would get a 1024x768 graphics login screen, but then X will die, and then restart, with the login screen again. Haven't tried 64 MB video RAM though -- got 128 MB right from the start.

So you suggest I install as 800x600, with default video RAM; then after installation's done, install the guest additions, shutdown guest, set vram to 64 MB, and then re-run sax2 on the guest?

Thanks again.

Well not really. I have installed OpenSUSE several times in VBox and the only thing that needs to be done to get the resolution to work is installing the suggestions above and the the guest additions. I have never needed to give more than 10 meg of Vram because I do not use the 3Deffects but if needed then 64 meg is enough. Perhaps you have a corrupt install if this does not work for you. After the additions are installed then you use the mouse drag to set the screen or you can use that host+f for full screen or the host+l for seamless.

thanks.

So, just to rephrase my questions, when you do a fresh install of OpenSUSE 11.1,
a) do you set your VRam = 64 MB when you create your VM, and BEFORE the OS install? and
b) do you change to a higher res (ie 1024 x 768) *AFTER* installing the guest additions?

Thanks again for your feedback.

Yes but you do not set the resolution in the guest.
You use the mouse drag method to resize the guest window or the hot keys to toggle full screen or seamless.
