Does Myth require GLX?
I'm running 0.18.1 from ATRPMS and outputting on an nvidia 5200 with
the 7667 drivers. I get errors when I try to run glxgears, and when
checking the X logs, it says that glx is disabled because it conflicts
with the support for the "Composite" X extension.
Yet, most of the discussion on this forum seems to imply that glx is a
normal part of the system... I'm hoping that this is the explanaion
for some of the instability I'm seeing.
From the NVIDIA README (
ftp://download.nvidia.com/XFree86/Linux-x86/1.0-7676/README.txt ):
Option "AllowGLXWithComposite" "boolean"
Enables GLX even when the Composite X extension is loaded. ENABLE AT
YOUR OWN RISK. OpenGL applications will not display correctly in many
circumstances with this setting enabled. Default: GLX is disabled when
Composite is loaded.
...
XVideo and the Composite X extension
XVideo will not work correctly when Composite is enabled. See Appendix
S.
...
Appendix S. The X Composite Extension
X.org version X11R6.8.0 contains experimental support for a new X protocol
extension called Composite. This extension allows windows to be drawn into
pixmaps instead of directly onto the screen.
In other words, the entire README (and your X logs) is, basically,
saying to turn off the Composite extension.
Remove the line
Option "Composite" "Enable"
And, if you leave an empty "Extensions" section, take it out, too.
