Description Suici Doga 2017-05-13 06:49:03 UTC 
When I try to run glxgears on a remote Cygwin / X server I get this error 

suici@HP-Pavilion-g7:~$ LIBGL_DEBUG=verbose DISPLAY=:0 glxgears
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so
libGL: Can't open configuration file /home/suici/.drirc: No such file or directory.
libGL: Can't open configuration file /home/suici/.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:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  149 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  28
  Current serial number in output stream:  30

I'm using Windows 10 WSL but the same error also occurs if I run it from a remote Linux machine. If I use +iglx the error goes but it only supports GL 1.4.

GPU : Radeon HD 7640G

Current versions of Xorg disable GLX indirect rendering by default. This is intended behaviour.
