In praise of grobi for auto-configuring X11 monitors
I have recently started using the grobi program by Alexander Neumann again and was delighted to discover that it makes using my fiddly (but wonderful) Dell 32-inch 8K monitor (UP3218K) monitor much more convenient — I get a signal more quickly than with my previous, sleep-based approach.
This will result in RandR output change events, which will trigger grobi, which will run xrandr, which configures the monitor. When I suspend my PC to RAM, I either want to wake it up manually later, for example by pressing a key on the keyboard or by sending a Wake-on-LAN packet, or I want it to wake up automatically each morning at 6:50 — that way, daily cron jobs have some time to run before I start using the computer. To accomplish this, I use zleep, a wrapper program around rtcwake(8) and systemctl suspend that integrates with the myStrom switch smart plug to turn off power to the monitor entirely.
