My main puter is a quad 2.66, 8gb ram, 295gtx graphics card. I installed ubuntu as my main OS on that computer.
I also have a Toshiba portegé which is a very nice portable laptop, however it can’t play any newer games. So… here it goes.
I have ubuntu installed on my laptop as well. I now use Virtual GL to “stream” the output from my gtx295 to my laptop by using a ssh connection with compressed jpegs. Remember to connect your laptop using a wired connection since wireless seems to work a bit slow.

Here is how you do it:
On your main puter install TurboJPEG and VirtualGL
First download the latest version of TurboJpeg from http://sourceforge.net/projects/virtualgl/files/
When i wrote this article the latest release was called: turbojpeg_1.11_amd64.deb *Note that this is the 64bit deb file if you are using 32bit ubuntu you should download the one called i386
Once downloaded it open up a terminal and cd into the folder where you saved turbojpeg and type the following:

sudo dpkg -i turbojpeg*.deb

now go to the http://sourceforge.net/projects/virtualgl/files/ again and download the latest version of VirtualGL
when i wrote this the latest version was called: VirtualGL_2.1.3_amd64.deb *Note that this is the 64bit deb file if you are using 32bit ubuntu you should download the one called i386
Once downloaded it open up a terminal and cd into the folder where you saved turbojpeg and type the following:

sudo dpkg -i VirtualGL*.deb

now do the same thing on your laptop.
once done switch back to your main puter again and install ssh

sudo apt-get install ssh

now edit the sshd_config file

sudo nano -w /etc/ssh/sshd_config

Locate the line that says X11Forwarding. If there is a # in front of the line remove it. Alter the line so it looks like this:

X11Forwarding yes

now restart your ssh

/etc/init.d/ssh restart

aight almost done… Go to your laptop and SSH to your main puter

ssh IPADRESS

after logging in stop the gdm server

/etc/init.d/gdm stop

now run vqlserver_config

/opt/VirtualGL/bin/vglserver_config

Select option 1
say no to the next 3 options.

restart the display manager:

/etc/init.d/gdm start

Exit the ssh connection

exit

aight now you are all ready to start playing

I allready installed The Witcher using wine so here is how to launch it from the laptop (replace user with the ssh username and <IPADRESS> with the adress of your main puter):

vglconnect user@<IPADRESS>
vglrun wine ~/.wine/drive_c/games/The.Witcher/System/witcher.exe

yey The Witcher starts up and u can play as if you where using the main puter

if it lags you can try to compress the jpeg images even more using the -q switch

vglrun -q 50 wine ~/.wine/drive_c/games/The.Witcher/System/witcher.exe

aight… thats all folks. Please feel free to comment or ask questions it u need any help.
Cheers

I’ll start out with the first one that should be over quite fast. Streaming games over LAN. I’d always wanted to play those new 3d games on my small lappy without any heating issues. Anyways the practical part and explanations will follow soon.

Cheers all
