Hello! My problem is that when I want to play a game, lxdream closes. I've opened it from console in linux and I get this:

18:14:39 00000000 WARN Could not initialize LIRC. LIRC hotkeys will be disabled.
18:14:39 00000000 WARN Failed to load plugin: '/usr/lib64/lxdream/input_lirc.so': Initialization failed
IRQ's not enabled, falling back to busy waits: 2 0
WARNING: Application /usr/bin/lxdream��?��@?��@?��@? calling GLX 1.3 function "glXCreatePbuffer" when GLX 1.3 is not supported! This is an application bug!

Gdk-ERROR **: The program 'lxdream' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
(Details: serial 1426 error_code 9 request_code 135 minor_code 7)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

Can anyone help me?

P.S: I'm Spanish, so probably I've some mistakes.

This is the output of glxinfo:

I've 3D acceleration in Fedora 12 because I've installed the mesa-dri-drivers-experimental package. My graphic card is an ATI Radeon HD 3450.

Yes, but actually ATI official drivers are incompatible with Fedora 12 =(

I hope that.

Thanks!
