As general info, and seeing how various Linux users will have to contend with "my keyboard is ignored" for these reasons when trying to set up a new installation, or get it to actually boot after installation, despite someone here whinging about an OT post: Some motherboards only respond to a PS/2 keyboard straight away, their USB keyboard input emulates the PS/2 keyboard, and may start to do that too late, or only if some BIOS option is set. There are often BIOS options to change this (legacy modes), but you have to get into it first. After bootup has started, it's your OS that takes over, and it's far more flexible. You may also have to try different USB ports to find the one they do this with (probably the nearest ones to the PS/2 ports). And on motherboards with no PS/2 sockets, you may find they also have specific USB ports they look for a USB keyboard on at boot time. If your motherboard has a mix of USB 1, 2, or 3 sockets, the lowest speed ones are probably its preferred keyboard ones (yours too, you want the high speed ports for other things). If you're fighting to get your motherboard to recognise a keypress before booting starts, you can try unplugging your HDD/SDD (first). You may get more of a chance. Once you do get into your BIOS/UEFI it's probably a good idea to look for an option that puts in a boot delay, give it a couple of seconds. You may find there's a fast boot option that ignores any user input before immediately booting the drive. And motherboards that show a logo while posting may also be an issue (you can try changing whatever it does now, to the opposite option). -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
