Description Andy Wingo 2008-06-29 06:51:36 UTC

Hi,

Running GLX clients under Xephyr fails with indirect contexts. To reproduce:

1. Run Xephyr: Xephyr :1 -ac -screen 800x600 &
2. Run gears with direct rendering: DISPLAY=:1 glxgears
   -- runs fine
3. Control-C the direct gears, then run it indirectly: DISPLAY=:1 LIBGL_ALWAYS_INDIRECT=1 glxgears
   -- gets the following error:

$ LIBGL_ALWAYS_INDIRECT=1 DISPLAY=:1 glxgears
X Error of failed request:  BadImplementation (server does not implement operation)
  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  5 (X_GLXMakeCurrent)
  Serial number of failed request:  22
  Current serial number in output stream:  22
X Error of failed request:  GLXBadDrawable
  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  11 (X_GLXSwapBuffers)
  Serial number of failed request:  23
  Current serial number in output stream:  111


My xephyr is from Fedora, but appears to be quite recent:
  xorg-x11-server-Xephyr-1.4.99.902-3.20080612.fc9.i386

I run intel drivers.
