It's telling you that your graphics card is too old to use the GLSL shaders, so you need to disable them in the config. You need support for at least OpenGL 2.1/GLSL 1.2.

(The correct title is "This is how the game actually looks like." )

**myconid** · August 12, 2012


preferglsl = false
gentangents = false
smoothlos = false

**fabio** · August 12, 2012

It looks someone commited them by accident and them someone other reverted it. You can remove your changes and update from svn, it should work.

The game probably should check if GLSL 1.2 is available before really enabling them, even if they are enabled by a user.

**Jeru** · August 12, 2012

thanks but how i can change it?

I did it for you, apparently only moderators can edit titles. (I think that is silly.)

**feneur** · August 12, 2012

Apparently someone has changed it since you wrote that, now it's definitely set as allowed

(One do need to use the "More Reply Options" though, which might not be apparent to everyone)

Hi guys!

The same problem here. The buildings, trees and units are invisible. Only blue selection circles...

One time I noticed a message 'failed to compile shader' and googled it and found this topic.

I looked at config file but these three options (preferglsl, gentangents, smoothlos) already set to 'false'.

Can anyone help to fix this problem?

0 A.D. Alpha 12 / Gentoo / NVidia GeForce GTX 550Ti / NVidia proprietary driver installed here.

Thanks in advance.

Pedro Falcão · February 27, 2013

You card is actually pretty good. Have you tried downloading newer drivers? Generally it solves the problem. Also, check this thread here: http://www.wildfiregames.com/forum/index.php?showtopic=16709 (might not be useful, but just to check...)

creaker · February 27, 2013

Thanks for reply!

I've updated driver from v.295.75 to v.310.32 but it doesn't helped.

But I noticed warning in konsole output : "NVIDIA: could not open the device file /dev/nvidiactl (Permission denied)."

I've changed permissions to 777 for this file. After that I got new message: "NVIDIA: could not open the device file /dev/nvidia0 (Permission denied)."

So I did the same trick on this file also (chmod 777).

Now all the units and buildings are visible.

May be this info would helpfull for someone else.

**quantumstate** · February 27, 2013

That doesn't sounds very safe. You have just given full access to those devices to anything on your machine. It might be worth looking for help somewhere else like a gentoo help forum.

**leper** · February 27, 2013

Try adding yourself to the video group. Instead of changing those permissions to something that could cause other issues in the long run.

creaker · February 27, 2013

leper, I did checked it: user already in video group.

quantumstate

It looks like something wrong in game itself because of game requires access to these two devices for other users than the owner and group.

Initially permissions was 660 for both of these files. Currently I set it to 666 (read-write without execution for all)

**leper** · February 27, 2013

It looks like something wrong in game itself because of game requires access to these two devices for other users than the owner and group.

In order for programs that use the NVIDIA driver to work correctly (e.g.: X, OpenGL, and CUDA applications), the kernel module must be loaded, and the device files /dev/nvidiactl and /dev/nvidia[0-9]+ must exist with read and write permissions for any users of such applications.

The nvidia driver readme says different.

Are the /dev/nvidia* devices actually set to the video group?

creaker · February 27, 2013

Yes, for these devices owner is set to "root" and group is set to "video"

User that starts the game also listed in video group.

It should be enough regardless other (non-video) users permissions (i.e. 660 should be enough). But I have not a units and buildings this case.

P.S.

I've changed permissions to 606 (group "video" blocked at all, no read-write-execute permissions for group) and game is works fine. So I guess that the problem not depends on listed the user in the group "video" or not.
