[SOLVED]xpra + winswitch - best practice due to /etc/X11/xorg.conf.d/*

Question

Running xpra causes some headaches.
The application builds fine and installs just perfectly, the troubles comes from the default Xorg configuration is no longer stored in /etc/X11/xorg.conf, it's now stored and read from numerous files under /etc/X11/xorg.conf.d/ where just so happen to be my 5-nvidia.conf.
Starting xpra via:
xpra start :100

tl;dr: 5-nvidia.conf is trying to get loaded after xf86-video-dummy is loaded (which is the default for xpra).
Now to the question: What's the best practice because there's no information about this issue, and i can't be the only one who's run in to this since the xorg.conf was removed. At the moment I move all my nvidia configs out of the way, start xpra and move them back in. This works for the better part as long as i execute xpra with my own scripts.
But is there a better way (which doesn't perhaps include recreating xorg.conf since that appears to be something you should walk away from)?

Answer 1

Good thinking! (xpra is basically just screen but for x, or a X11 tunnel via SSH).
After a really quick poking around and remembering that xpra really just uses xorg-server-xvfb and at the very bottom of /etc/xpra/xpra.conf there's a line that says:
xvfb=xpra_Xdummy -dpi 96 -noreset -nolisten tcp +extension GLX +extension RANDR +extension RENDER -logfile ${HOME}/.xpra/Xorg.${DISPLAY}.log -config /etc/xpra/xorg.conf
Appending -configdir appears to be working.
Here are the full steps:
[torxed@archie ~]$ sudo cp -r /etc/X11/xorg.conf.d /etc/xpra/
[torxed@archie ~]$ sudo rm /etc/xpra/xorg.conf.d/*nvidia*
[torxed@archie ~]$ sudo sed -i '$s/$/ -configdir \/etc\/xpra\/xpra.conf.d/' /etc/xpra/xpra.conf
*nvidia* would have to match your graphic-driver-config that would cause xorg-server-xvbf to crash.
I'll update the wiki and put a mention on the package about it because this either has to be standard or well known from the start because it really just breaks the package all together.
