Commander X16

On Ubuntu I get this when I try to launch the emulator both built from src and precompiled.

 

X Error of failed request:  BadValue (integer parameter out of range for operation)

  Major opcode of failed request:  152 (GLX)

  Minor opcode of failed request:  3 (X_GLXCreateContext)

  Value in failed request:  0x0

  Serial number of failed request:  110

  Current serial number in output stream:  111

 

If you're on a laptop, make sure the emulator is using the discrete graphics adapter instead of the integrated one
