libGL error: failed to load driver: swrast

I'm trying to launch Dungeon Defenders but this happens:

$ ./DungeonDefenders --LIBGL_DEBUG=verbose
Dungeon Defenders: Installed in '/home/casa/Giochi/DungeonDefenders'.
libGL error: failed to load driver: swrast
libGL error: Try again with LIBGL_DEBUG=verbose for more details.
X Error of failed request:  GLXUnsupportedPrivateRequest
  Major opcode of failed request:  153 (GLX)
  Minor opcode of failed request:  16 (X_GLXVendorPrivate)
  Serial number of failed request:  239
  Current serial number in output stream:  242

It's the same for other gamese (Aquaria, Amnesia: The Dark Descent, Penumbra: Overture, ...).
Can't find much with Google and can't understand what this "swrast" is.
I'm NOT using a double VGA system (like any modern iCore + nVIDIA + Optimus) but an old system with Core 2 Duo + GTX260.

Als I don't understand how to do this:

Try again with LIBGL_DEBUG=verbose for more details

use it like this :

LIBGL_DEBUG=verbose ./DungeonDefenders

swrast is a software driver that is used as a fallback if there's no accelerated video available.

please post the output of glxinfo .

Re: libGL error: failed to load driver: swrast

Hi,

I have a nvidia card and installing lib32-nvidia-libgl lib32-nvidia-utils solved this problems to me. I was trying to run Safari on Arch with Playonlinux and I got an error message like yours.

sudo pacman -S lib32-nvidia-libgl lib32-nvidia-utils
