It finally arrived!! Last week the Beta-version of Left 4 Dead 2 arrived on Steam for Linux..

I (as well as many other gamers) have been waiting for months for this glorious game to hit the Linux platform.. Even though the game is now about 4 years old (released late 2009), the gameplay is still worth spending the £19.99 that Steam charges for this game, if you haven’t already purchased it for Windows..

Left 4 Dead 2 (L4D2) was the first game that Valve (the company behind Steam) ported to the Linux platform in the fall as a proof-of-concept.. but it took them more than half a year to get it ready for the Beta level..

Also the speed of the game as been increased from the Windows Direct3D implementation, so former Windows users will get a performance boost for those FPS-hungry types out there…

I think this is a big step towards more Linux games and this together with nVidia’s decision to offer support for their Optimus chipset, tells me that hardware companies as well as the gaming industry has finally accepted that gaming on Linux is a reality, and not something they want to miss out on..

Happy Zombie-slaying out there!!!

nVidia has announced that a new beta driver is available here.

A source here claims that this means official nVidia support for the Optimus technology… I’m not sure I reading it the same way.. but will test it as soon as possible and report back…

Still I would like to give a big thumbs-up to the guys at “The Bumblebee Project“, who picked up on some of my original ideas from my bumblebee code and perfected it.. Great job guys…

In November, the game-deployment-platform Steam, launched their closed Beta for Linux…

Just before Christmas the Beta was opened up to the Public…

And I must say, that I’m impressed.. It’s working great…

Right now “only” 57 games are available for Linux, see here, But more are arriving every week..

The only free game right now is Team Fortress 2, but a lot of the other games here are pretty cheap.. And I don’t mind spending a little money on games if they are worth it…

Steam can be downloaded here for Ubuntu, and should be convertable to other distros by just unpacking the file..

Happy gaming everyone…

Hi all

Just wanted to share some good experience, and I hope that this info will help some of you..

I just reinstalled my primary gaming machine from Windows 7 to Kubuntu.. Have had two seperate machines (1 windows and 1 linux) for years, but since the release of the Steam beta, I’m now convinced that I can use Linux on the primary one…

Primary computer:
Dell Precision 490
2x Quad 2.66 GHz Xeon processors
16 GB Ram
nVidia GTX 560 TI

I installed Diablo 3 by creating a wine bottle with:

WINEPREFIX=<bottle path> WINEARCH=win32 winecfg

then installed:

WINEPREFIX=<bottle path> WINEARCH=win32 winetricks vcrun2008

and Diablo:

WINEPREFIX=<bottle path> WINEARCH=win32 wine <diablo installer>

After waiting for the installer to download and install, the game started fine, but after entering a game, I noticed that the performance was horrible.. about 10 fps…

I fooled around with all kinds of wine and nvidia tweak settings, as well as taskset for locking the game to one physical CPU… this only gave me a few extra frames…

I then noticed that when disabling window effects in KDE (Shift+Alt+F12), I got a HUGE performance boost…

Now I’m running at about 40-70 fps, with all effects maxed…

On windows I have had alot of problems with microstuttering on Diablo, but I seems to have completely vanished on Kubuntu…

Happy gaming everyone…

I have been using XBMC and MythBox (http://code.google.com/p/mythbox/) as a frontend for MythTV Backend for quite a while now, and because MythBox doesn’t support MythTV 0.25, I have been stuck on the old 0.24 branch…

But now some of the guys over at the MythBox community has found a solution.. This requires some patching of XBMC, and a speciel version of MythBox.. all descriped here.

I have eased up this process a little by rebuilding the XBMC version bundled with Ubuntu 12.04 with the 0.25 changes.. this version is now available here:

https://launchpad.net/~mj-casalogic/+archive/xbmc-mythbox

Easy step-by-step guide on howto install:

sudo apt-add-repository ppa:mj-casalogic/xbmc-mythbox

sudo apt-get update

sudo apt-get install xbmc

cd ~
git clone https://github.com/mitchcapper/mythbox.git

mv -f ~/.xbmc/addons/script.mythbox ~  # or just rm -rf
ln -s ~/mythbox ~/.xbmc/addons/script.mythbox

and that should be it... 

Happy TV watching...

A computer is like air conditioning: it becomes useless when you open Windows.

For years and years I (as many others) have waited for Diablo 3. And now it’s finally here!!

For all gaming Linux people, one of the biggest excitements about new games is if they will run under Wine.

And Diablo 3 does.. Almost…

There are still some patching which haven’t (yet) been merged into standard wine, but besides of that it really runs well.

If you want to follow the way I run Diablo 3 on my Alienware X11M, here it goes:

I now think I have gotten the last problems sorted out, and CBS is now running perfectly on my CentOS server..

Signing service is now also working..

I’m still missing a few RHEL dependencies, but I hope to get this sorted out soon…

Once again, the installation instructions:

First of all, remember to setup either DNS or /etc/hosts to match hostname of the server…

RHEL6:

wget -O /etc/yum.repos.d/RHEL-CBS.repo http://download.opensuse.org/repositories/home:/martin-juhl:/branches:/openSUSE:/Tools/RHEL_6/home:martin-juhl:branches:openSUSE:Tools.repo

or

CentOS6:

wget -O /etc/yum.repos.d/CentOS-CBS.repo http://download.opensuse.org/repositories/home:/martin-juhl:/branches:/openSUSE:/Tools/CentOS_6/home:martin-juhl:branches:openSUSE:Tools.repo

For dependencies we also need the EPEL repository:

rpm -ivh http://ftp.crc.dk/fedora-epel/6/i386/epel-release-6-5.noarch.rpm

yum install obs-web-httpd obs-server obs-worker obs-api mysql-server

chkconfig obsworker on
chkconfig iptables off
chkconfig mysqld on
service mysqld start

Configure:
/etc/sysconfig/obs-server

Set:
OBS_API_AUTOSETUP=”no”
to:
OBS_API_AUTOSETUP=”yes”

and:
OBS_VM_TYPE=”auto”
to:
OBS_VM_TYPE=”none”

/etc/init.d/obsapisetup start

mv /etc/httpd/conf.d/ssl.conf /etc/httpd/conf.d/ssl.conf.bak

chkconfig httpd on
chkconfig obssignd on

reboot

Now go the servers IP-adresse/Hostname for the web-interface…

Login: Admin

Pass: opensuse

Just a quick update on the CBS project:

Everything seems to be running now, except for the obssigner..

obssigner needs obs-signd installed, and right now I have some problems building some of the dependencies.. but we’re moving forward..
