Screen flickering in my Asus Extensa 215-54

Dear All

I have a weird screen flickering issue with my laptop. Due to the flickering issue I have changed the OS in the laptop from Windows to Linux thinking that there may be a display driver issue. I have used Endeavour OS , Fedora and finally settled on my favorite Garuda OS. In all the distros there was no flickering issue. But today the flickering started in my Garuda OS and I had to force shut down the system.

Here my Garuda Inxi

Also note that the flickering issue still persist if I use Windows in this machine. As soon as I login to Windows the screen starts flickering.

Any help will be appreciated.

Your BIOS version looks relatively recent, but still I would take a peek and see if there have been any updates released. If a newer BIOS version offers bug fixes I would take it.

I would recommend testing out some other kernels. Most likely when you were running these other distros, you were using a different kernel. Try the "vanilla" kernel; first bring your system fully up to date:


Then install the kernel and headers:

sudo pacman -S linux linux-headers

You can boot to your new kernel by selecting advanced boot options in the Grub menu.

Other good kernels to test would be the LTS kernel (older kernel version) or the mainline kernel (newer kernel version).


Here is an uneducated guess: Maybe your display is flickering if your system is hot or overheating. Go to Garuda Assistant, disable all performance options, apply and wait to see if the display flickers.

I tested with different kernels, after the first encounter in garuda linux, I have not encountered the issue for the second time.
But I decided to change the distro to OpenSUSE and there the issue still exists. While I am working randomly the screen flickers. In my two days of using OpenSUSE atleast 5 times the screen flickered. Now I am back to Garuda and will see if the problem arises again.

Dear All

I have noticed something about the error. The error only occur when there is heavy load on the RAM.
@BluishHumility @dr460nf1r3 - Could this be because of a faulty RAM in my system ??


Test your ram with MemTest86 or similar and see if any issues are detected.
