Default extension "XFree86-VidModeExtension" missing

Okey, I just tried running the game from linux to see if the performance is any better, but I got the "Unsupported video card" message. The terminal displayed this message:

Xlib: extension "XFree86-VidModeExtension" missing on display ":1.0".

I am running Ubuntu 7.10 x86_64, I have an Nvidia Go 7600 gpu, running beryl

Tell me what config files you need me to paste so I can start looking for solutions

oh, the libxxf86vm1 package is installed, as well as libxxf86vm1-dev and libxxf86vm1-dbg.

PS: The game works fine in windows.

EDIT: Forgot to mention: gpu drivers used are the ones from the package manager, if i ever learned anything in ubuntu is "STICK WITH PACKAGES"

Miraculix,

Turn Beryl off when playing games.

If the problem persists, you know where to post back.

I assume you have the nVidia acceleration enabled, try doing:

Code:
glxinfo | grep direct
Just to be sure.

Also look at your /etc/X11/xorg.conf file if you have commented the "dri" line. Oh, and look in the repositories (through Synaptics or aptitude) the "libxx" string. There are some packages related to the "XFree86-VidModeExtension" extension.

I have:

Code:
libxxf86dga1
libxxf86dga-dev
libxxf86misc1
libxxf86misc-dev
libxxf86vm1
libxxf86vm-dev

PS: Bonehead's right, turn beryl off... It does not only kill the performance of the game, but makes X11 behave in strange ways. Anyway, it looks pretty :P

Well I got good news: I got the game working in a very strange way: No window decorations :/ I did this using this:

export DISPLAY=:0.0

before running the launcher. The good thing is I could just copy over all my dloaded resources from windows! TONS of thanks to Froste for helping me in #regnumonline with this.

hm how can I get rid of the xgl session and have a simple x-session on the :0.0 display?

At startup, on the session manager at GDM (when you put your password and username) you have a Session button. Choose GNOME Session and that should work :P

make sure you tell ppl it has *no* window decorations, and since it runs on :0.0 it will display above everything else (even the rotating cube) since xgl runs on :1.0.

At any rate. getting rid of xgl and all the beryl/compiz eye-candy was easy, and i should have done it long ago. Had a couple of issues with compiz leaving a key in gconf rendering it the default window manager, causing gnome-volume-manager to hang at boot (wtf? ). At any rate, I'm gonna give linux try for a few lvls. Not as pretty, but maybe it's worth it performance-wise.
