I'm trying to use LXQt on Devuan ASCII / Debian Stretch.

At some point after the desktop environment is started, Alt+Tab strats triggering QWin crashes, whose stderr text says Cannot create platform OpenGL context, neither GLX nor EGL are enabled.

Now, I've had my share of troubles with GLX/EGL with a previous distribution; you see, I'm using my on-board graphics to feed my monitor, but I also have a monitor output on my nVIDIA GTX 650 Ti Boost; this card I only use for CUDA experimentation, not for display. Still, having it probably causes some drivers and pieces of software to assume the GPU is being used for display, and be confounded by it's failure to respond.

PS - I also have CUDA installed, with the latest nVISDIA GPU driver, in case that matters.
