After some pretty disappointing experiences with VMWare on Ubuntu, I tried out VirtualBox.
WinXP runs very fast in VirtualBox.
Use the non-open source version of VirtualBox. Do not install the virtualbox-ose version from the Gutsy repos or else you do not get USB support.
Add following line /etc/apt/sources.list:
1 |
deb <a href="http://www.virtualbox.org/debian" target="_blank">http://www.virtualbox.org/debian</a> gutsy non-free |
The innotek public key for apt-secure can be downloaded here. You can add this key with
1 |
apt-key add innotek.asc |
You may need to install some additional libraries on your Linux system in order to run VirtualBox (I didn’t)- in particular, you will need libxalan-c, libxerces-c and version 5 of libstdc++.
Now install VirtualBox from synaptic.
The following is required to get USB support working.
Edit the file /etc/udev/rules.d/40-
3.1 Search for the following lines
12 # USB devices (usbfs replacement)SUBSYSTEM=="usb_device", MODE="0664"
3.2 Change them to the following
12 # USB devices (usbfs replacement)SUBSYSTEM=="usb_device", MODE="0666"
Basically, in the file /etc/init.d/mountdevsubfs.sh you need to edit the lines:
1 2 3 4 5 6 7 8 |
# # Magic to make /proc/bus/usb work # #mkdir -p /dev/bus/usb/.usbfs #domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644 #ln -s .usbfs/devices /dev/bus/usb/devices #mount --rbind /dev/bus/usb /proc/bus/usb |
to look like this (removing four #’s):
1 2 3 4 5 6 7 8 |
# # Magic to make /proc/bus/usb work # mkdir -p /dev/bus/usb/.usbfs domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644 ln -s .usbfs/devices /dev/bus/usb/devices mount --rbind /dev/bus/usb /proc/bus/usb |
To copy VMs, ( for example, to copy the VM named ARMDev to XPTemplate) issue the command:
VBoxManage clonevdi ARMDev.vdi XPTemplate.vdi
Backup your xorg.conf file first. Really. You have been warned.

If you accidentally brush the touchpad with your thumb while typing, the mouse move + click that occurs can change your insertion point to someplace else and you end up typing where you don’t want to. Follow the instructions at
http://ubuntu.wordpress.com/2006/09/20/disable-touchpad-temporarily-when-typing/
to disable the touchpad while typing.
edit /usr/bin/compiz and do 2 searches for intel then comment out the following line
T=”$T 8086:2982 8086:2992 8086:29a2 8086:2a02 8086:2a12″Â # intel 965
This line blacklists the i965gm x3100 graphics chipset from compiz due to video playing problems (and sure enough, you cannot play videos with Compiz active).
Then from the menu, select System->Preferences->
You can also install the compizconfig-settings-manager module to enable even more insane desktop effects.

Add the xorg.conf entries first, then install gsynaptic and then reboot (or restart X)
My MaxSpeed is 1.5
Add this to your xorg.conf file. Then restart X (Ctrl-Alt-Bksp). Save any unsaved work before restarting X.
Option “AccelFactor” “0.25”

Install VLC. Totem-gstreamer will not work properly with DVDs
You may need to go to
/usr/share/doc/libdvdread3 and run
$ sudo ./install-css.sh
to install the DVD decrypter codec, but i am not sure.
Reboot and then use VLC to play the DVD.
