Recently, when I start Dropbox from terminal, I always get the libGL error:
/opt/dropbox/dropbox start libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast
I googled, and luckily found this. I followed the instructions, and get the following output:
% glxinfo name of display: :0 libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast X Error of failed request: GLXBadContext Major opcode of failed request: 153 (GLX) Minor opcode of failed request: 6 (X_GLXIsDirect) Serial number of failed request: 46 Current serial number in output stream: 45 % glxgears libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 153 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 35 Current serial number in output stream: 37 % export LIBGL_DEBUG=verbose % glxinfo name of display: :0 libGL: screen 0 does not appear to be DRI2 capable libGL: OpenDriver: trying /usr/lib64/dri/tls/swrast_dri.so libGL: OpenDriver: trying /usr/lib64/dri/swrast_dri.so libGL: Can't open configuration file /home/nostalgia/.drirc: No such file or directory. libGL: Can't open configuration file /home/nostalgia/.drirc: No such file or directory. libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast X Error of failed request: GLXBadContext Major opcode of failed request: 153 (GLX) Minor opcode of failed request: 6 (X_GLXIsDirect) Serial number of failed request: 46 Current serial number in output stream: 45
There are two OpenGL implementations on my Gentoo Linux:
% eselect opengl list Available OpenGL implementations: [1] nvidia * [2] xorg-x11
As you see, currently, I’m using the nvidia implementation.
And there are quite a lot libGL.so files on my box:
% locate libGL.so

So I doubt that if the glxgears/glxinfo command is using the inappropriate libGL.so file. How to detect which libGL.so file I’m using? Of course, with strace:
% strace -o /tmp/libGL.strace glxgears
I checked the /tmp/libGL.strace file, and found that the called libGL.so file is /usr/lib64/libGL.so.1, which is a symbolic link to /usr/lib64/libGL.so.1.2.0, the default xorg-x11 OpenGL implementation.
Now, it’s quite clear: I only need to point /usr/lib64/libGL.so.1 to the nvidia OpenGL .so implementation, which is /usr/lib64/opengl/nvidia/lib/libGL.so.1.0.0:
% sudo ln -fs /usr/lib64/opengl/nvidia/lib/libGL.so.1.0.0 /usr/lib64/libGL.so.1
And test again:
% glxinfo | grep direct direct rendering: Yes
Now, everything works like a charm!
