Screen gets dark and flickers after signing in

[Generic_Us3rnam3]

Just installed a fresh copy of Manjaro, and I immediately noticed that the screen seemed way to dark despite the brightness being maxed out. When I restarted the system, the login screen was the normal brightness, but it went back to being dark as soon as I signed in. It also flickers whenever there is white on screen.

Please provide the output of:

inxi --filter --verbosity=8

or the short form (preferred):

inxi -zv8

• inxi man pages (Arch Manual)

Running `inxi` in `chroot`

@Running `inxi` in `chroot`

If you need to run inxi from within a chroot environment, and find the output is laced with unexpected 12’s, please try again with:

• Add to the long form command: --color=0
• or, change the short form to: inxi -zv8c0

Providing `inxi` when you cannot access your desktop environment

@Providing `inxi` when you cannot access your desktop environment

If you are unable to copy and paste the inxi output due to being unable to access your desktop, but can still access a TTY text session, then you can send the inxi output to a pastebin service:

inxi -zv8c0 | nc termbin.com 9999

Note: the nc command may require installation of the openbsd-netcat package:

pamac install openbsd-netcat

or

sudo pacman -Syu openbsd-netcat

After the output is sent, a link to the inxi output will be provided, which you can then add to your forum post.

If you are not allowed to post links in the forum due to being a new member, you can still paste the link as code by typing 3 backticks ``` on empty lines above and below the pasted URL.

@Your privacy is respected

When inxi is run using the --filter or -z parameters, any personally identifiable information is filtered from the resulting output.

Any code or command output (such as inxi output) should be placed within a scrollable pre-formatted text enclosure according to forum guidelines.

[Mini How-To] format code or command output

Select and copy all the text in the Terminal window (minus the prompt, if you are using zsh).

Then paste the output in between two lines containing three backticks:
```
or three tildes:

Or:

Copy & paste, then highlight the pasted text and click the </> button at the top of the reply window (easier for smaller outputs).

This is a known bug in Plasma 6.7, related to the screen dimming. It will be fixed when Manjaro gets the next Plasma release. The only way around it for now is to disable the dimming.

Unfortunately, I cannot tell you when the next Plasma update will arrive (in Manjaro), but if you are impatient, then you can always switch to the Testing branch and see whether it too still has the issue. Manjaro Testing currently has Plasma 6.7.5, while Manjaro Stable is still on 6.7.4.

sudo pacman-mirrors -a -B testing && sudo pacman -Syyu

My automatic screen brightness seems to work fine most of the time.
