I am running my Qt application with Linux Frame Buffer by using "export QWS_DISPLAY=LinuxFb"
Once my application starts and displays using the Linux Fb, how do I add vncscreen driver?
I have tried doing "export QWS_DISPLAY=VNC:LinuxFb" when the application is running. But it did not enable the vnc.
How do i remove the screen driver?
Environment variables are passed to the application once before it is started. Any modification of environment variables will not be reflected in those seen by the program. Furthermore environment variables are defined per environment -- if you have two shells (or any other processes actually) then changing environment variables in one of them will not be reflected in the other (which is a direct consequence of what I wrote earlier).
