Keyboard detection problem on the start screen

[francky-carbone]

Hi everyone,

since the acquisition of a new computer (installed with 20.04), my USB keyboard is not recognized on the session start screen when the computer was previously turned off. I have to disconnect and reconnect the USB connection of the keyboard to recover control.


This problem is not present after a reboot, and the keyboard is well recognized and functional in the BIOS. I tried to change the only keyboard setting in the BIOS with NumLock on / off, but nothing helps.


Do you have an idea ?


Thank you in advance

Problem with Xorg ? X11 ? LightDM ? Grub ?


Thank you in advance
