Based on an initial work of mk@, we (Fabien and I) start working on rndis over usb support for OpenBSD.
After some work we finally ping google with the htc hero

A small post about my graphviz / dot experiments.

The python script needs to be polished. I will publish it as soon as it is finished.

Nowadays, I would like to use my 3 dell 17″ screen, but I was bored because Xorg multicard was broken for a while. After some google I found x2x, and I ask todd@ who said is working fine, so I give it a shot.

Here is my installation :

The laptop is connect to a dock, itself connected to an external screen.
The desktop is a classical computer, with mouse, keyboard and 2 screens.


laptop # pkg_add x2x
laptop # echo "X11Forwarding yes" >> /etc/ssh/sshd_config
desktop $ ssh -X dbd@laptop "x2x -west -to :0&" &


This give me a nice result, and even the clipboard is shared ! :

Some times ago, I was nostalgic about old games so I decided to try both emulation and game-pad support.

The beginning of the adventure was to compile and try Sdlmame and Sdlmess, fortunatly Pierre Riteau was smart enough to answer all my questions, so I got some good result and I was able to play Metal Slug and Alex Kid.

Some random tips:

• Use opengl mode if you can, it is a lot faster (-video opengl)
• To have the good keymap use “-keymap -keymap_file /usr/local/share/sdlmame/keymaps/km-LANG.txt“

The second step was to play with a game-pad, so I searched the mailing list and found that the Logitech DualAction was working fine under OpenBSD.

I got one easily. If you want one it costs about 25 € in the market, I’ve tried the Logitech RumblePad and it works fine too.

A bug prevents you to use the game-pad using the sdl{mame,mess} menu, you have to directly run the game because it is trying to detect twice the game-pad and cannot see it the second time. For example, to run metal slug X I use :

sdlmame -keymap -keymap_file /usr/local/share/sdlmame/keymaps/km-fr.txt -video opengl mslugx

As I was going to a friend house, we decided to get some real fun, we had two gamepads and

we just replaced the PS3 with an OpenBSD box on the tv (it has a VGA connector), add some xrandr magic and you got a nice gaming screen.

Finally you got a nice gaming station, thanks to Pierre Riteau for the port and the answers, oga@ for his DRM/DRI work and Fabien for the hosting and the tv.

I want to be able to use a few softwares with the sound at the same time and OpenBSD just got it, the new sound server which starts as complicated as aucat -l and which just works with an incredible lightness :

25024 dbd 3:04  1.00% aucat

I use sndio output for xmms, sdl and vlc.

I think that I need to offer some beer to ratchov@ (I’ve just seen that he’s living in the same city than I do).

My GNS3 0.6 update hit the ports tree !

Like sthen@ noticed, GNS developpers forgot to raise version number in setup.py so we had to add a little hack in the makefile :

MODPY_EGG_VERSION=	0.5
V=			0.6
DISTNAME=		GNS3-$V-src
PKGNAME=		gns3-$V
