Powering off the monitor crashes `dwl` #9

Closed johanengstrand closed 2 years ago

johanengstrand commented 2 years ago

Powering off/on my monitor will often crash dwl. After the crash (to the TTY, not sure if it happens when I turn the monitor off or when I turn the monitor back on again), the TTY shows something like

Failed to query (GET_INFO) UVC control 2 on unit1 -32 (exp. 1).
[     v412-utils.c: 1125 spa_v412_enum_controls()] '/dev/video0' VIDIOC_QUERYCTRL: Input/output error

Sometimes, it manages to restart the herd service and bring me back into a new dwl-guile session after I have turned the monitor back on again.

Upstream issue or something related to our implementation?
