[mythtv-users] black screen at "watch tv" -- RingBuf (fd -1) error

I was having that same issue.  I also saw it other times including when
running glxgears.  After commenting out glx from xorg.conf I was stable.
After a bit more digging I found out that xorg.conf was loading the
wrong libglx.so.  I did the quick and dirty copy of libglx.so out of
the /usr/lib/xorg/modules/extensions/nvidia directory
into /usr/lib/xorg/modules/extensions/ and all is good.  The correct fix
is probably to put a ModulePath entry in xorg.conf, but since
nvidia-settings likes to overwrite xorg.conf every time I make a change
(and I'm experimenting on getting good tv settings) I did it the hack
way.
