[SOLVED] 30 seconds hang at boot

[kensiko]

Trying to understand what's causing a hang on a PC connected to a TV in our living room with a freshly installed Kubuntu. Troubleshooted a bit, exported logs. Just wondering if anybody had a similar issue.

PC specs:
ASrock B450M Pro
Ryzen 2600
8GB Ram
500GB Western Digital Black nVME SSD
MSI RX580
40in Philips TV connected with HDMI

Spent more time tonight. Installed boottchart and eventually found out it was due to input-remapper that was blocking boots due to multiple devices bug.

Changed input remapper device to be non blocking

/etc/udev/rules.d/60-input-remapper-daemon.rules

RUN+="/usr/bin/systemd-run --no-block /bin/input-remapper-control --command autoload --device $env{DEVNAME}"
