---------

http://bugs.winehq.org/show_bug.cgi?id=31161 points to a packaging bug, either in Ubuntu's s2tc or mesa

Relevant quote:

> Note that Wine needs the 32-bit version of that package though.

Actually I had it installed. But it seems like there is a bug in ubuntu i386
package. I had to create a proper symbolic link:

sudo ln -s libtxc_dxtn_s2tc.so.0 /usr/lib/i386-linux-gnu/libtxc_dxtn.so

Now I can see the menu.

To summarize:

1) If you're using opensource graphics drivers, you have to install
libtxc-dxtn-s2tc
2) make sure you have libtxc-dxtn-s2tc0:i386 installed.
3) run with MESA_DEBUG=1 to see if there are warning couldn't open
libtxc_dxtn.so
4) If you're in Ubuntu 12.04 rewrite a link
/usr/lib/i386-linux-gnu/libtxc_dxtn.so to point to
/usr/lib/i386-linux-gnu/libtxc_dxtn_s2tc.so.0

Hopefully, this thread will help somebody.

I tried running the game under opensource video drivers and couldn't see the menu.
Also I have a plenty of messages:

err:d3d_surface:surface_upload_data >>>>>>>>>>>>>>>>> GL_INVALID_ENUM (0x500) from glTexSubImage2D @ surface.c / 2369

Googling around: https://bugs.freedesktop.org/show_bug.cgi?id=49484
tells it is because "an application tries to use a (D3D) format (e.g.
DXT/s3tc) even though it's not available."

I think it is a bug in wine. It should check for available formats and stop if requested is not available and print a message how to fix it.

Why format and type are 0?

Typically because you don't have s3tc support. I'll see if I can improve the message a bit to make it more obvious.

Actually, you wouldn't get that message for DXTn surfaces, though you might for float textures. Could you see what the attached patch outputs?

It outputs:

Running with MESA_DEBUG=1 shows:

Mesa warning: couldn't open libtxc_dxtn.so, software DXTn compression/decompression unavailable

Its strange, because I have libtxc-dxtn-s2tc0 installed.

Yeah, that's missing s3tc support. The glTexSubImage2D() call confused me for a bit because it shouldn't be called for compressed formats, but if the format is missing WINED3DFMT_FLAG_COMPRESSED wouldn't be set either.

 Note that Wine needs the 32-bit version of that package though.

What *.so file do you mean? If you mean libtxc_dxtn.so, than it's not wine, it's mesa.

Hello Scott, or anyone else affected,

Accepted s2tc into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/s2tc/0~git20110809-2.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I confirmed in the other bug that the alternatives and symlinks look good, but it'd be best if someone could also confirm that a software affecting by these bugs is actually fixed with the packages from -proposed.

Agreed regarding the release; I don't personally have the game in question to test, I was simply forwarding a Wine bug.
