Subject: [PATCH] monitor-manager: only reuse initial-config if monitor
topology matches startup
Right now we try to apply the current monitor config when a new
monitor is attached. The current config obviously doesn't include the
new monitor, so the new monitor isn't lit up.
The only reason we apply the current config at all is to handle the
startup case: We want to reuse the config set in Xorg when first
logging in.
This commit changes the code to look at the *initial config* instead
of the current config, and only if the new monitor topology matches
the start up topology.
