Description Andrian Nord 2010-05-15 14:03:15 UTC
When running glx programs with dri2-enabled mesa on client side, it will return

X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  128 (DRI2)
  Minor opcode of failed request:  1 (DRI2Connect)
  Serial number of failed request:  19
  Current serial number in output stream:  19

export LIBG_ALWAYS_INDIRECT=1
does the trick
Comment 1 Andrian Nord 2010-05-15 14:12:18 UTC
P.S. It seems to be unclear, but with mesa on client side, that are old enough to not have dri2, it's working just ok.

Does your server have DRI2?  It sounds like it does not.
Comment 3 Andrian Nord 2010-05-16 04:27:39 UTC
Server side:
night@nord ~ % glxinfo| grep DRI2
OpenGL renderer string: Mesa DRI R600 (RV710 9553) 20090101  TCL DRI2
From log:
[  1776.639] (II) RADEON(0): [DRI2] Setup complete
[  1776.639] (II) RADEON(0): [DRI2]   DRI driver: r600
[  1777.054] (II) GLX: Initialized DRI2 GL provider for screen 0

Client side is other machine: indirect glx -> via network.

A less robust version was tested by the reporter on IRC.
