Display state does not change after prefix change in cfg.yaml.

Possibly resolved by dirty removal in #22

alex-courtis commented 2 years ago

Lid state is not being notified until after the first round of output layout changes.

Perform lid discovery without polling fd before main loop.

Only occurring on 2019 Thinkpad X1. Similar age Dell is OK.

alex-courtis commented 2 years ago

Hacking libinput indicates that AttrLidSwitchReliability=reliable is necessary for the initial state to be sent and functions on the thinkpad when forced on.

/usr/share/libinput/10-generic-lid.quirks will set reliable for devices with a dmi containing ct9 and ct10 only. The thinkpad is ct31.

alex-courtis commented 2 years ago

Raised https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/753 for the ct31 switch. Changing the default would be preferable...

alex-courtis commented 2 years ago

Added workaround to readme.
