My Acer nitro5 AN5-15-55 laptop keyboard backlight is working , only red is available, (and I cannot adjust keyboard backlight brightness), but

the back light 'sleeps' when I am not typing? I can't see anything before typing. How to keep the backlght always on? (The reason is when its dark I cant see the keyboard letters at all in beginning , it only lights up when I type so I have to press the space bar or make typo always first time to enable the back light on in Ubuntu 20.10?)

Also in Windows I am able to adjust the keyboard backlight different colours, but how to adjust the keyboard backilght colours in Ubuntu 20.10? Is it possible?

I found solution

For my question 1) "the back light 'sleeps' when I am not typing? I can't see anything before typing. How to keep the backlght always on? (The reason is when its dark I cant see the keyboard letters at all in beginning , it only lights up when I type so I have to press the space bar or make typo always first time to enable the back light on in Ubuntu 20.10?)"

(SOLVED): reboot, press F2 to enter BIOS. In BIOS Main section there should be a setting "Keyboard Backlight Sleep" , it is enabled by default so then set to "disable". Save and exit bios.

In ubuntu 20.10 now my keyboard is peristent ON. Success.

for part 2) change keyboard backlight colours if you are sure RGB keyboard then try "OpenRGB" - https://gitlab.com/CalcProgrammer1/OpenRGB and (must first) check if your RGB keyboard is listed before proceeding. (Some MSI users have bricked motherboards without checking first so read the details pre-installation). Alternatives are here also here as well - https://github.com/withinboredom/system-76-keyboards here - https://github.com/Gibtnix/MSIKLM and here - https://github.com/wroberts/rogauracore
