Fix screen resolution for BackTrack VM under VirtualBox

Revisions: 20110521 - Revised to show the fix for BT5

On BT5

The following worked with no fuss:

# Xorg -configure
# cp /root/xorg.conf.new /etc/X11/xorg.conf
# startx

And that’s it!

On BT4

Note to self.  To fix the screen resolution for X on a host running BackTrack on VirtualBox…

Modify the “Screen” section in /etc/X11/xorg.conf to read as follows:

Section "Screen"
Identifier           "Default Screen"
Monitor             "Configured Monitor"
Device               "Configured Video Device"
DefaultDepth     24
SubSection "Display"
Depth    24
Modes   "1024x768" "800x600"
EndSubSection
EndSection

    Does not work. The only available resolutions are still 800×600 and 640×480.

    On OS X Lion (10.7.2) you might need to first run one of the following at an OS X Terminal prompt:

    VboxManage setextradata Backtrack CustomVideoMode1 1100×740x16
    VboxManage setextradata Backtrack CustomVideoMode1 1440×900x16

    Then run either the BT5 or BT4 Terminal commands shown above after logging into BT but before running startx.

    I was able to achieve 1024×768 from X11.

    I’m still working out if I can get to a higher X11 screen size.
