Hi,
I use cygwin from home (on a Windows box) to ssh into my machine at work
(Linux box). I get the following error when I try to run programs that use
opengl libs for displaying:
cdernst AT clinton cubit90]$ glxgears
Xlib: extension "GLX" missing on display "localhost:10.0".
Error: couldn't get an RGB, Double-buffered visual
When I ssh, I use the -X option so that graphics get forwarded to my local
machine. I am aware that this error is usually manifested because opengl
libs are not installed on the local machine, but I know I have them on my
local machine because if I go a 'glxgears' before ssh-ing the gears
graphics window displays just fine. It appears that after ssh-ing into my
work machine, display information is lost.
What is very troubling with this problem is that sometimes the problem
altogether disappears. For example, if I ssh into my work machine and let
the terminal sit for a while, it sometimes works, sometimes not. Other
times after ssh-ing in, if I edit a file with "vim" I can run glxgears
after, but not always. Nothing is reproducable to get it to work. But
once it starts displaying, it usually doesn't stop. I tried a complete
uninstall/reinstall of cygwin but it didn't do anything.
Help!
