I can not get Nexuiz to run on linux. Is it because I am running the very latest components xorg-server-1.1.99.903 Mesa from git. Glx works and other gl games, has anyone got it running with xorg-7.2-RC3? All I get is the logo screen, before installing 2.2 patch I didn't even get that. Here is the output:

It would be new to me that mesa can run anything more advanced then hello world at more then 5 frames per second.. What 'other games' did you test mesa with sofar? I doubt anything quake like would run very fast.. Ok there are free 3d accelerated drivers (r300) for some ati cards but i could you do not mean those.

[SavageX]

As far as I can see he is using hardware accelerated DRI drivers for Intel integrated graphic chipsets. Those should be able to at least start Nexuiz.

[esteel]

Ahh ok right it states intel dri, cool. I missed that fact.
So you might try to use this parameter when starting nexuiz, maybe it will help (please report back if it does or does not help). -notexturenonpoweroftwo
like:
cd /PATH/TO/NEXUIZ
./nexuiz-linux-sdl.sh -notexturenonpoweroftwo

Newer versions of Nexuiz use that OpenGL extension and i just learned that mesa reports that extension to seems to screw it up (just like mac..) and maybe dri also makes this error.

[froghopper]

Thanks for the suggestion, that param didn't seem to have any effect. I can at least confirm that the vid card + mem etc are sufficient to run the game, though not very fast, as it runs under dual booted windows.

Oh and fairly graphics intensive games such as blob&conquer and billiardsGL run under linux.

[esteel]

Meh i can't sleep.. After looking again at your log output the line

intel_mipmap_tree.c:215: intel_miptree_set_image_offset: Assertion `img < mt->level[level].nr_images' failed.

does seem to come from the dri driver. So it would be really helpful if you file a bug report for them at the right spot. I have no clue who is responsible for them.

You can take a look here: http://141.2.16.3:7780/nex there you will find debugging versions of the nexuiz engine which you can use together with a debugger to find out more precisely were the crash is happening.

An other thing to try is to use the startup parameter
+r_glsl 0
which will disable a huge load of things that might be a problem for weaker cards/drivers (but which also might be a slowdown for the game..)

I doubt that'll change anything. OpenGL shaders are compiled after the first map is loaded, but in this case the crash seems to occur when the first images for the menu are loaded. GLSL shouldn't have anything to do with that...

I've just tested 2.2.2 on my notebook (Intel GMA 950 GPU (i945GM chipset)/Mesa 6.5.1): both (glx & sdl) binaries are running fine, so whatever the problem is, it seems limited to certain chipsets...
