Screen flickering on lockscreen, hdmi, etc. everywhere

Hello and thank you for viewing this topic. I’ve used manjaro for long time with kde and ext4. This time i decided to install xfce with btrfs. There was no problem with the previous setup so the issue might be with xfce or btrfs i dont know. My laptop’s screen is flickering when screen locked due to waiting and when i connected hdmi and change settings 1 or 2 times its flickering again. I’ve recorded a video so you can see it. Can you help me ?

:+1: Welcome to Manjaro! :+1:

On a:

there is no need to be running a Stable Development kernel, so please read this:

Especially the Linux has multiple kernels section and then install an LTS kernel and try again.

Unrelated to your current problem but:

Of your 4GB RAM, you’re losing 760 MB to your video display and have only 3230 MB left which is 72.8% full without loading any applications, so look around for a second-hand 8 GB RAM DIMM for your machine. (or 4GB if you’re really cash-strapped: 20€ will get you at least double of what you have now)


I am really thankful. I’ve just switched to a LTS kernel and it’s solved. By the way about the ram, it’s just too expensive here locally.
