Modify Resolution of Linuxmint Guest OS on Virtualbox

zergl 2015-02-08
-------------------------
By default, the resolution of guest OS, linuxmint 17.1, is 800*600. I would help after installing the additional support package based on path experiment:

# sh VBoxLinuxAdditions.run

But it didn't work this time. Got some tips from the internet, I have to build a new /etc/X11/xorg.conf manully. The configuration as followed could support 1024*768:


Section "Monitor"
Identifier "Monitor0"
VendorName "Generic Vendor"
ModelName "Generic Monitor"
Option "DPMS"
HorizSync 28-50
VertRefresh 43-73

Section "Device"

VendorName "Videocard vendor"

EndSection
