I am running a linux-host for Qt-software-development at a central place.
With my windows box I use Xming as a local X-server and putty to connect to that linux-host. With this configuration I can use all X (xclock, xterm) and GLX (qtcreator, gxlinfo, glxgears...) programs at the linux-host.
My main workstation is a ubuntu 14.04 LTS with a nvidia gfx card. When I connect to the linux-host with my ubuntu-system using "ssh -p port# -YC my.dev.host.com" I also can use all X programs (xclock, xterm) programs but I can not use GLX programs (qtcreator, gxlinfo, glxgears...).
As far I learned this is because the X-server dont support indirect GLX contexts by default for version younger 1.16.
So my questions ist: How can I enable indirect GLX contexts (X-server and nvidida driver) in my ubuntu 14.04 LTS installation to get things working as expected from a X-server.
Thank you for any help!
Here is the output of glxgears, maybe that helps:
