Manjaro KDE screen flickers on my ASUS laptop

Is that a permanent solution? In the terminal, I tried…

set i915.enable_psr=0

…But for that to work, I had to restart Manjaro thereafter, and it only works when I type it in and restart.

I assume, in /etc/default/grub, there is a text file where I can edit GRUB_CMDLINE_LINUX="" to GRUB_CMDLINE_LINUX="i915.enable_psr=0", yes? I’ll find out when I boot up Manjaro again. My knowledge of Linux is nowhere close to that of Windows or Android.

Yes, it’s permanent if it works. Edit the file /etc/default/grub with sudo, then run sudo update-grub in terminal and reboot.

I found the grub text file, made the change to GRUB_CMDLINE_LINUX="", then ran ‘sudo update-grub’ in the terminal. Unfortunately it didn’t work, unless GRUB_CMDLINE_LINUX="" appears more than once in that grub file and they need to be changed.

and you rebooted after making the change?

Post another inxi --admin --verbosity=7 --filter --no-host --width so we can verify, please?

Yes. Twice I checked that text file, and at least twice I rebooted. It still flickers. I hope my BIOS upgrade didn’t disturb any chance of it working.

I tried it this way: inxi --admin --verbosity=7 --filter --no-host --width

But the sooner I try to paste the info, I get, “Sorry, you can’t include links in your post.”

There are no links in the info. What is this message board interpreting as links?

Please read this and follow instructions there and you won’t have that problem:

As I said before, I tried to paste the entire system info after running the command in the terminal, and this message board rejected it, interpreting some of the material within as links. Is there a way to work around that problem?

Never mind.

Well i see nothing that jumps out as why this is happening… is the screen flicker bad enough you cant try changing your resolution or refresh rate?

:grin:

From a system perspective it looks good, so:

  1. Does this also happen if you create a new user user and log in there? (E.G. cookymonzta2)
  2. Have you tried a newer stable (5.13) or experimental (5.1 RC6) yet as you do have a quite new machine…

:thinking:

No effect. The new user is tied to the same glitches as the old. KDE 5.22.4 did no good, either.

Sorry: I meant Kernel:

  • If you get lost, please remember Ctrl+Alt+F1 is your friend!

  • Print this page so you have it as a reference while in TTY2

  • Log off

  • Switch to TTY2 by pressing Ctrl+Alt+F2

  • Log in there

  • Execute:

    sudo mhwd-kernel --install linux513
    sudo mhwd-kernel --install linux514
    
    • to ensure grub is showing, execute:

      sudo nano --backup /etc/default/grub
      
    • Change (or add?) the following 3 lines:

      GRUB_TIMEOUT=3
      #GRUB_HIDDEN_TIMEOUT=0
      #GRUB_TIMEOUT_STYLE=hidden
      

      (3 or higher is fine, add the # before the lines above if those lines are present)

    • Ctrl+X Y Enter to save if there is anything to save

    • If you did save, execute:

      sudo update-grub
      
    • Reboot

  • Go to grub’s Advanced options

  • Choose these kernels one by one and try them out one by one and see if that helps.

  • If not, remove them again…

Too many errors, could not resolve host, failed to synchronize all databases, invalid url for server.

Just a sample of the errors I got with this failed update. Neither kernel installed.

I must remind you that I have 2 operating systems on my laptop, on separate SSDs (Manjaro on Drive 0 and Windows 10, pre-installed, on drive 1). I wonder if the flickers are caused by the name I chose for my laptop in Manjaro. I have the same name for Windows 10. My Windows XP VM (in VMware Workstation) was flagged with “A duplicate name exists on the network”; same computer name as my main Win10 OS. I changed the name in my VM and the error disappeared.

And how do I get my Manjaro setup to detect my Wi-Fi signal? My Windows setup had no problem detecting multiple nearby Wi-Fi networks upon system installation. I had to use a USB-to-RJ45 Ethernet interface to get an Internet connection in Manjaro and install the OS.

  • Hook up a network cable
  • Try again
  • Please provide full output

:thinking:

I tried it with the network cable. I’ve been installing updates all along with the network cable because I can’t find the software to enable Wi-Fi in Manjaro and I don’t know the appropriate command for the terminal to search the repositories the Web.

Kernel 5.13 would not install in TTY2. I looked as if it had trouble finding the repositories there…

…But it had no trouble when I ran the same commands in the main OS. I used the terminal, of course…

My last 3 reboots displayed no flickering. It remains to be seen if Manjaro in this laptop stays stable.

Remove the solution if the problem starts again, but in the meantime, anyone having the same problem as you, will find a solution!

:wink:

Unfortunately it still flickers, on and off, almost with every other reboot. I noticed on some occasions that it is stable when the clock is wrong (the OS has a habit of setting the clock back 4 hours early or the Windows clock 4 hours ahead).

I’ve removed just about every suggestion from the GRUB text file (it is now back to its original code), but left Kernel 5.13 in place.

Unfortunately, I can’t help you any further as you’ve reached the end of my Intel GPU knowledge…

:sob:
