So you are using a PS/2 keyboard, and a PS/2 mouse, so we will need to check the flags I was mentioning in my previous comment. I think those that have the best chance of being useful are i8042.notimeout and i8042.nomux. So please append those 2 flags to the kernel boot line in grub ("i8042.notimeout=1 i8042.nomux=1"), and try to boot, and reboot, and reboot :) If these 2 flags reliably make both the touchpad and keyboard work, we will need to check which one is the right one (so please do the same tests with only one flag). Note: there might be an other slightly less tedious option which would consist in providing a dmesg of a failed keyboard/touchpad boot with i8042.debug=1. -> In that case make sure to test the keyboard before typing a password (cause the length can be detected from the number of key events, but the keys are masked). So please beware in such situation to not type the LUKS password or your password with the embedded keyboard.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
