Computer won't have black screen but instead go to sleep

Support
1

i think it is because of a problem with the computer and not linux… but i’m not sure… [it also happened on ubuntu in the past…]
anyway it is my media center computer with gnome.

as i said… when i set it to have a blank screen after let’s say 10 minutes it is instead goes to sleep. it happens while i didn’t choose any sleep setting… i can make a screenshot so you can better know…

is it really a computer problem and not a linux problem in your opinion?

at the moment i set the screen to be on all the time but i don’t want my television screen to have problems because of it… as some LEDs can go bad…

do you need to know more about my hardware? which command do i need to make so i can bring the information you need?

be patient as i’m not an advanced user…
thank you

have you try with theses kernels
linux6.6 LTS , linux6.1 LTS ans 5.15 LTS ?

no. is it complicated to switch between kernels?
are these newer kernels?

6

just add theses kernels , with manjaro settings
( or sudo mhwd-kernel -i linux515 )

change this option on Grub boot ( or press Esc on boot )

and go in advanced section to choose version kernel on boot

i will try soon.
do you assume it will solve the problem?

8

you should always have more than one version kernel installed , in case it goes wrong in boot

@candlightandskull

You seem to have abandoned this topic.

Please, always return to make a closing comment rather than leaving everything hanging in the air.

Have you solved your issue?

Tell us about it. :loudspeaker:

Not if you do it properly;

This is good advice.

Unlike some other Linux distributions, Manjaro allows to have several kernels installed at the same time; so, you always have another kernel to let you boot if you have problems.

Quick tip;

Important: Always install another kernel before uninstalling any that you don’t want or need.

Regards.
