Also, it is possible for most settings to be dynamic, which is useful on a laptop where you can plug screens, with XSETTINGS. That's what Gnome and XFCE are using. With Awesome WM, I am using a script [1] to update XSETTINGS (through xsettingsd configuration file). I explain more on my blog [2].

Nice, thanks for sharing! At most I've also hooked up a projector to my computer, but never needed to deal with any setting changes really (just for gaming or rarely for a presentation). A little off topic, but I've run into some weird issues with Display Port/Nvidia/Dell monitor where the monitor is not recognized on unplug/replug. In the past I know there were some issues with older Nvidia drivers and this particular monitor (P2715Q), though this seems like a weird problem that I've seen others have with different configurations online. It led to me needing a weird set of steps (I wrote about this in my Valve Index impressions [0]), using xrandr to add the display mode and switching to a virtual console too. I'm guessing this is mostly due to the older Dell monitor which has always been a bit wonky with Display Port. I assume things are better these days more broadly. Relevant part of [0]: xrandr --newmode "4K" 533.250 3840 3888 3920 4000 2160 2163 2168 2222 +hsync -vsync xrandr --addmode DP-0 4K xrandr --output DP-0 --mode 4K # switch to virtual terminal, i.e. Ctrl-Alt-F2 # switch to DisplayPort input on monitor which should display the terminal env DISPLAY=:0 xset dpms force off; sleep 5; env DISPLAY=:0 xset dpms force on # switch back to X, i.e. Ctrl-Alt-F7 The modeline to add can be found ahead of time with xrandr --verbose or using a tool like cvt or gtf (see the Arch wiki). Sometimes, though, I just need to power cycle the monitor or unplug and replug some cables. I hope this is just this older hardware, and probably solved, like everything else here, with a new GPU that has more DisplayPort outputs.
