Hi

I've had trouble with booting my system recently and have had to edit the parameters during boot. I have a long boot line (kernel text + 115 chars of optional params) and getting to the right place (about char 80) is very tedious. The key repeat seems to be very slow. It also buffers the key repeats. I release the key and the cursor continues moving for several seconds. I need to press the arrow key, hold it down and guess when it's going to get where I want it.

Also nice to have would be ctrl+left/right to navigate one "word" at a time.

Thanks

Brendan

are you booting grub in BIOS or UEFI mode? GRUB in BIOS mode is
usually pretty slow because it constantly has to switch between real
and protected mode. In UEFI, GRUB is running at full speed.

Ofc, that doesn't help you if you need to boot in BIOS mode, but it's
a hint at where the slowness may come from.

Thanks
Michael

Not an issue.

Doesn't matter.
Most common reason for slowness is high graphics resolution.
