Sorry about the extra size email, it is confusing. Yes, running with
the /dev/nvidia* devices labeled as xserver_misc_device_t will allow the
X server to run and login.. etc. However it does NOT allow glxinfo or
glxgears to run (they complain about access permissions
to /dev/nvidiactl). I need policy that will allow user programs access
{ read write } to /dev/nvidiactl before any OpenGL apps will run with
these drivers (the same issue happens for Quake3, AAOps.. not just these
GL test tools).
Perhaps the solution involves including each game in games.fc?
The same problem may exist for running with the new nvidia dri software
for OpenGL, I did not check yet, but will. If the problem does not
exist for that then a similar setup for nvidiactl may work, I'm not
sure.
