VirtualBox Shared Folders between Ubuntu Guest and Mac Host

You’ll need the latest version of VirtualBox (1.6) with Guest Additions installed in Ubuntu.

• With the Virtual Machine powered off and selected in VirtualBox, go to:
  Machine > Settings… > Shared Folders
• For “Folder Path”, click the icon to browse for the folder you want to share.
• For “Folder Name”, enter a name to describe the share.
• Click “OK” and start the virtual machine again.
• Create a mount point which is basically an empty folder.
• Fire up the terminal and type:
  sudo mount -t vboxsf folder_name path_to_mount_point
  folder_name is the name you typed in earlier to describe the share
• Woot! You should be able to browse the shared folder now.

Ubuntu Resolution Fix using VirtualBox on MacBook

I recently installed Ubuntu Hardy Heron via VirtualBox on my MacBook. Everything worked great except I only had the option of 800×600 and 640×480 for screen resolution. However, my MacBook’s resolution goes up to 1280×800. To get the maximum resolution, edit xorg.conf and restart. See the code below for the edits.

To edit the xorg.conf file. Fire up the terminal in Ubuntu and type:

$ sudo gedit /etc/X11/xorg.conf

Then find and replace the following:

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"vboxvideo"
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Generic Monitor"
	Device		"VirtualBox graphics card"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1280x800" "800x600" "640x480"
	EndSubSection
EndSection

– Finally, restart Ubuntu and enjoy!
