When I try to run glxgears locally, it displays the initial gears,
but now they are just frozen. It doesn't work remotely, either,
which was what I tried initially. It *used* to work -- remotely
at 20-30 frames/second (as measured by fraps).
Interestingly enough, I get a glx window, -- fraps will display
30 (the right number for my screen refresh rate), in the right corner
of the glxgears window... but the gears don't move.
Same effect happens when I try remotely. Window comes up with gears
displayed, but no motion. Fraps also shows 30 FPS.
When I do glxinfo (with LIBGL_DEBUG=verbose), I get (more below):
name of display: :0
display: :0 screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

When I try remote display, the above is pretty much the same except
I get an error on the client system that it can't load the 3d swrast.so
driver on the other end.
But it sees pretty much the same capabilities -- FWIW, there is next to zilch
network traffic happening when I try this.. I mean while it is happening.
Before and after ~ 200-400KB/s (xosview), during, all my X windows become
very slow and no longer refresh steadily. Network throughput registers a drop to
1-80KB/s. Despite that -- xwin pegs a cpu @100% and stays that way
until I exit glxgears.
xwin log is below... Any ideas?
