OS: CentOS Linux release 7.0.1406 (Core)

Kernel: 3.10.0-123.8.1.el7.x86_64

When I run xcrysden (http://www.xcrysden.org/) remotely through ssh -X, it crashes with error:

"libGL error: failed to load driver: r600

libGL error: Try again with LIBGL_DEBUG=verbose for more details."

But this happens only in ssh session. The program runs well locally.

The crash happens for only some programs but not all. I can run X programs such xterm, gnome-terminal, evince ... with ssh normally. But when I run glxgears or glxinfo through ssh, it gives the same error.

$  LIBGL_DEBUG=verbose  glxinfo
name of display: localhost:12.0
libGL: OpenDriver: trying /usr/lib64/dri/tls/r600_dri.so
libGL: OpenDriver: trying /usr/lib64/dri/r600_dri.so
libGL error: failed to open drm device: No such file or directory
libGL error: failed to load driver: r600
libGL: OpenDriver: trying /usr/lib64/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib64/dri/swrast_dri.so

Does anyone know how to solve this problem?

  • You should [read this](http://unix.stackexchange.com/a/76017/25985) and see if you can forward `glxdemo` with your current method. – goldilocks Jan 31 '15 at 14:02
