I am running automated tests on an app while recording the desktop for future analysis.
I am working from a standard Ubuntu Linux setup.
I would like to be able to switch to another user while these tests are running to continue working on other tasks.
When I switch to another user using a different virtual console logging in and starting a second x11 session using startx the screen recording of the X11 server running on Ctrl+Alt+F7 records nothing but a black screen.
I have discovered that this is because the X11 screen buffer stops rendering on none active run levels .
What configuration setting for X11 keeps will keep it rendering when switched away from that virtual console?
Patching and building X11 is not preferable but acceptable .
