Hi, The first concern is not that annoying and about a wireless mouse that has systematically two different behaviours: 1. one if the receiver is already plugged at boot, 2. one if it is plugged while linux has boot. For 1. the mouse is like going quickly into sleep mode each time I do not move it and then take a few instants to wake up, For 2. the mouse is okl.
Could this be related to any power profiles or power management tool? The second is quite recent (1/2 months ago?) related to the internal keyboard. Either everything is fine with the keyboard or either all the keyboard is not working well. Every key has a sort of delay and some key events seem to be lost. And it is the case both using the TTY or the DE (GNOME). I do not see any messages (dmesg / journalctl) that could help me to track this. I just suspect some racing init steps during boot but... Is there any tool to track when this problem occurs? Finally it seems to me that there is an abundance of input files in /dev/input. $ sudo ls /dev/input by-id event0 event10 event12 event14 event16 event18 event2 event21 event23 event3 event5 event7 event9 mouse0 mouse2 by-path event1 event11 event13 event15 event17 event19 event20 event22 event24 event4 event6 event8 mice mouse1 and some duplicates looking at the boot messages (for instance
