I did a fresh install on Arch Linux using GNOME-Shell 3.4. When I started OpenLP with dual monitors (NVIDIA GPU) GNOME-Shell became unresponsive and all sorts of problems, only solution was to go to tty and kill OpenLP. I searched OpenLP.conf for a way to disable and did not see it (I have included it) I could have missed it. I could however disable my second monitor via NVIDIA settins and open OpenLP without issues, disable X11 Bypass renable the second monitor and all is well. I am not for sure if there is a reasonable way to even think about a fix for this, but it would be nice if there was a simple change in the config file at least. After disabling X11 Bypass i could see "x11%20bypass%20wm=false"
I tried this same thing on an Intel GPU and had identical results. My question as much as anything is if users come up with this problem what would be the best solution? I'm guessing entering "x11 bypass=false" in the OpenLP.conf should take care of this?
Or best to tell them to log into a non-3d version of their desktop or disconnect the second montor all allowed OpenLP to function well and then you could get in to disable the option, my only concern is that first impressions carry a lot of weight with people and opening an app up and it making your desktop unusable doesn't leave a real good first impression.
Wrst: Can you test my branch? Does it work? (I don't have gnome, so we need all scenarios to be tested).
