desmume

ixhabbaba · 04-16-2009, 03:04 PM

I get the following terminal output when running Nintendo DS
emulator desmume:

(desmume-glade:9178): GdkGLExt-WARNING **: cannot create GdkGLPixmap

Failed to create the GdkGLPixmap
Failed to setup openGL 3D emulation; removing 3D support

I run Mandriva One Spring 2008 on an Intel Centrino laptop.
My video card is some integrated Intel card, with 256 MB memory.
I appear to have drivers for it.

Any help is much appreciated. Thank you.

Can you please lookup which type of video card you have on the laptop? "some centrino cpu with some integrated video card" is a tad vague.

if you run

Code:

glxinfo | grep "Direct rendering"

Does it say "yes"?

While this link about 3d in X is for linux, generally the info is a great source for any of the OSes:
http://www.linuxquestions.org/questi...in-x11-402003/

Especially the parts regarding testing whether 3d works, and the adjustments to your X configuration.

Why, soitenly. Thank you for the quick reply, too.

This is the card: 82852/855GM Integrated Graphics Device
Mandriva says it uses this driver for it: Card:Intel 810 and later
This is my CPU, while were at it: ‎Intel(R) Pentium(R) M processor 1.70GHz

Nope, there's no "Direct Rendering" entry in glxinfo.

I've applied the changes to xorg.conf described in the tutorial, yet the problem persists.
glxinfo now says
direct rendering: Yes

EDIT: I noticed the error message from desmume changed to:
(desmume:9538): GdkGLExt-WARNING **: glXMakeCurrent() failed
Failed to initialise openGL 3D emulation; removing 3D support

Good, your video driver now is aware to make use of the 3D abilities of your GPU.

Have you restarted X after you made the changes?

When I look up the error and check desmume there's a few points to say here:
- desmume is in alpha, update to the latest release whenever possible. Chances are this is / was a bug in desmume
- The error you now get seems to be related to multi-threaded and opengl due to bad video drivers which have tls so one thread cannot read from another thread so they need a supervisor thread that does the 3d stuff. A bit elaborate way to say, very likely a bug you won't be able to fix other than waiting and updating desmume whenever there's a new release and update your video drivers to the latest level.

Yes, I've restarted X.

Okay, but the drivers as well as desmume are at the latest devel
already, so I'll just have to wait, I suppose.
Thanks for helping me out.

You don't mention what version of desmume you were trying. I got that error with version 0.9.1 (Debian Squeeze as of this writing) and found this thread. I then updated it to 0.9.2 (Debian Sid aotw), and the error was fixed.

Fwiw:

Code:

alucard@thrawn:~$ lspci | grep Graphics
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
alucard@thrawn:~$ glxinfo | grep -i "Direct rendering"
direct rendering: Yes
