Can't get guest to use 1680x1050 resolution

Postby swarsron » 30. Oct 2009, 12:45

Hi,

i added a new resolution via
VBoxControl.exe addcustommode 1680 1050 32
but it doesn't get listed as a resolution i can chose in the windows dialog nor can
i switch to it via
VBoxControl.exe setvideomode 1680 1050 32

I can add 1680 600 32 and it gets listed in the windows resolution dialog. I configured
the guest to have 64 mb video ram since i figured that 32 won't cut it, but that doesn't
change anything. Since there is no error message i can't figure out what seems to be
the problem. Any suggestions?

Thanks
swarsron

Guest additions installed?
What is the resolution of the host?
What is VBoxControl.exe? Do you mean VBoxManage?

yes, they are installed.
Host resolution is 1680x1050
No, i mean VBoxControl.exe (C:\Programme\Sun\VirtualBox Guest Additions\VBoxControl.exe), there
is no VBoxManage* file in there

Well I have never heard of doing it that way.
Why not try the way that VBox suggests?
Look at Chapter 8. VBoxManage reference and controlvm.

Note: this is done from the host

Or you can simply use the host+F key inside the guest to toggle full screen.

i managed to get 1680x1050 by switching to seamless mode and back, voila, i could
choose it, don't ask me why.

Thank you for your help, if it didn't work by chance i would know where to look at now

I have a similar problem - see another thread - with a vm that is locked at 800x600x32 irrespective of how much I play with full screen mode, seamless mode and the other alternatives. I took a look at the online user manual, chapter 8, as suggested in a post in this thread and there is nothing in there about setting the video mode. The only reference to video is references to vrdp, and none of the settings appear to adjust resolution.

When I run VBoxManage showvminfo "My vm" I see amongst other lines:

Video mode: 800x600x32

Unfortunately I cannot find a file containing this info, which I could change and test. Can anyone tell me where this information is stored? I would have expected it to be in one of the xml files in my .Virtualbox directory, but if so, it does not include the words "Video mode" nor the mode "800x600".

TIA

Fixed my problem with:

VBoxManage setextradata "Z7" "CustomVideoMode1" "1280x650x32"
