I have a bash script which iterates over xinput entries and assigns 3
USB touchscreen inputs to 3 respective displays using xinput
map-to-output. This command is super slow (we're talking about 30+
seconds to complete), whereas on other processors and setups this can be
done in a second or less.
I used to think the issue was with xinput, however, other xinput
commands work decently quick, whereas it is typing xrandr where I
noticed a similar, though shorter, lag. So the issue is with the
connection to the monitors.
I am using DisplayPort ports, with Benfei DisplayPort-to-HDMI adapters
to connect to 3 HDMI displays, on a debian elkhart lake intel processor.
Is there anything I can do to make commands affecting the displays run
normally, without this abnormal lag? There is zero lag on the displays
themselves, so the issue seems more with processing the display input
than the data being sent on the cable itself.
