azag is my December (2024) new laptop. A Tuxedo model.

Sharing keyboard, mouse and screen with yzao

Since 24 October (2026), I've connected azag and yzao through Deskflow, so that the former can lend its keyboard and mouse to the latter.

Ctrl+Alt+→: keyboard and mouse over to yzao.
Ctrl+Alt+←: back to azag.

While on yzao, the pointer is locked there and its moves are sent relative (relativeMouseMoves). With Deskflow's default absolute positions, the jump KWin gives the pointer to the opposite edge after a desktop switch was undone at the next movement, and the pointer stayed glued to the edge it came from.

Each switch flashes the machine's name, big, half-transparent and for about a third of a second, in the middle of the screen it lands on. This is ~/bin/deskflow-flash, a small GTK popup that takes no focus, run by azag's Deskflow on entering and on leaving azag; yzao's older Deskflow cannot run commands, so azag reaches it over ssh with a key that can do nothing else.

The BenQ EW2880U screen switches inputs from the command line (DDC/CI): benq-input azag or benq-input yzao, which works even while the BenQ is showing the other machine. azag is on HDMI-2 and yzao goes to HDMI-1. Once yzao is on HDMI, the screen will switch along with another hotkey, as I find it convenient to not shift screen (for menial things on yzao's little screen, this is fine).

Both laptops have their address reserved on the router (DHCP binding), since yzao finds azag at a fixed address. The settings live in ~/.var/app/org.deskflow.deskflow/config/Deskflow/: Deskflow.conf, and the hotkeys in Deskflow-server.conf.
