Re: Cannot switch to another session with 100.14.11.
Yea it's complete nonsense. I've been starting multiple X servers on any card and with any driver I've ever used during the past 8 years, for example to run full screen gaming sessions on a dedicated X server. If this doesn't work any more it's clearly a bug. And even if it is another feature nvidia intentionally canceled (like overlays, dga, ...) it's still a bug and should be viewed as such.
