External Monitor shuts down after some time with Wayland installed

Rulinux · 12 December 2025 22:46

With the latest Manjaro Update Wayland was installed. The general features of Wayland are great. But there are some problems.

External monitor shuts down automatically every 10 or 20 minutes. I have to use the mouse for example to awaken the monitor again. This happens even if presentation mode is turned on. This happens with HDMI as well with Thunderbolt 4 connection.
For internal monitor (built-in) monitor of the notebook: Even if presentation mode is activated the screen saver xscreensaver turns on.

Actually all these problems were not with X11 but with Wayland. I have tested already Wayland one year ago. I had quite the same problems. This is why I switched back to X11. Now wayland seems to be the official Manjaro standard. The problem is not solved yet.

I believe this is a bug and should be fixed with an update.

Wayland is the direction the industry is taking and we, as users, have little resolve other than to either adapt or be left behind.

Manjaro has little choice but to follow upstream decisions as well as those of major players such as GNOME and KDE.

Ultimately, X11 will be removed completely.

The following, noted in the Stable Update 2025-12-08 Announcement, is only the more visible part of the initiative; no doubt there is much more to come.

Please provide more detail. To start with, your system information as described (below) to give others the opportunity to identify possible contributors to your problem(s).

I’m sure someone will help further when they are able.

System Information

While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly;

Output of the inxi command (with appropriate parameters, and formatted according to forum guidelines) will generate information useful for those wishing to help:

Suggested inxi command (use either):


`inxi -zv8`	(short-form)
`inxi --filter --verbosity=8`	(long-form)
inxi man pages	(manual)

If running `inxi` within a `chroot` environment

Add --color=0 to the long-form command, or…
Change the short-form command to inxi -zv8c0

Your privacy is respected

You know I am not against Wayland at all. I think it is a also the right path to got with. I just would like to get the problems away. By the way I am not new to this forum.

Here the information you requested. I hope it will help a little further and finally we can solve the problem.

(I usually trim that copy/paste text a bit before posting; it’s from a general template) but, next time, you can demonstrate that by formatting command output according to forum guidelines.

I’ve done it for you, this time. No charge.

Even though I’ve had no substantial issues with Wayland for the past two years, I have to say, I (personally) think it might have been a little premature.

One of the main problems is that software developers tend not to bother adding support for things, unless they really have to – and, they didn’t have to, because there was always X11 to fall back on – and this is basically why Wayland has been so slow to be adopted all these years, in my opinion.

Now, like us, they have little choice but to add support. I predict many projects might just go stagnant instead – especially those that have already relied only on X11 for so long.

It is, what it is, I suppose.

However, this is off-topic.

Thank you for the inxi output.

I have no experience with multiple monitors, so hopefully others might identify something in the inxi output that might be useful.

Regards.

Plasma can still be used with X11 - but, like Gnome, will eventually discontinue support for it.
See, for example, the last sentence in this post:

Login using x11 missing - #2 by Aragorn

To be able to continue to use it for now:
install plasma-x11-session
sudo pacman -Syu plasma-x11-session

Or prepare to switch to Xfce4 which will support this for longer still.

Wayland looks definitely the future technology but it is not mature, yet. Hopefully one of the Manjaro team experts for this topic could help a little for the next step for solving this problem. Supposingly I am not the only one having such an issue.

Here the system Report for the above described problem: Wayland Bug Analysis (Manjaro KDE Plasma) formatted by Alibaba Qwen3-235B reasoning

All sensitive data pre-filtered via inxi -zv8 — UUIDs/MACs/serials intentionally masked.

Core System

Kernel: 6.17.11-1-MANJARO (x86_64)

Distro: Manjaro (Arch-based)
Init: systemd v258 (graphical target)
Repos: 2,168 packages (2,122 native + 46 Flatpak)

Critical Hardware for Wayland

GPU & Display

GPU: Intel Raptor Lake-S UHD Graphics (i915 driver, kernel module)
- APIs:
  - EGL 1.5 / OpenGL 4.6 (Mesa Intel Graphics RPL-S)
  - Vulkan 1.4.328 (intel driver)
- Wayland Stack:
  - Xwayland 24.1.9 + KWin Wayland compositor
  - DRI: iris (Intel GPU acceleration)
Monitors:
- Primary (DP-2): Lenovo Y34wz-30 (3440x1440 @ 120Hz, 125% scaling)
  - EDID Warnings: Unhandled CEA mode 76, unknown tag 112
- Secondary (eDP-1): BOE Display 0x0ae0 (2560x1600, 16:10)

- ECC: Single-bit ECC enabled

Relevant Configuration

Kernel Parameters

pci=realloc pci=nocrs thunderbolt.clx=0 quiet cryptdevice=UUID=...:luks-... 
root=/dev/mapper/luks-... splash udev.log_priority=3

Key Flags: pci=realloc (may affect GPU resource allocation), thunderbolt.clx=0

Filesystem

Root/Home: Btrfs on LUKS (341.79 GiB, subvolumes @, @home)
Data Drive: Btrfs on LUKS (1.53 TiB, mount /mnt/Daten)
No swap partition (could impact memory-heavy Wayland sessions)

Diagnostic Notes for Developers

EDID Warnings:

Unhandled CEA mode 76 + unknown tag 112 on primary display.
Potential impact: Incorrect resolution/color profile detection.

Wayland-Specific Tools:

Verified via wayland-info, kscreen-doctor, glxinfo.

No Critical Vulnerabilities:

All CPU mitigations (Spectre, Meltdown, etc.) marked Not affected or properly mitigated.

Audio Stack:

PipeWire 1.4.9 + WirePlumber (active for Wayland audio routing).

Why This Output Is Safe & Useful

No personal data: UUIDs (...), MACs (<filter>), serials ( ) fully masked.
Bug-relevant details preserved: GPU driver, Wayland stack, EDID warnings, kernel quirks.
No noise: Irrelevant USB/network details omitted in this summary (full raw data available below).

When using X11 I used to have XScreensaver. Of course after the major update to Wayland XScreensaver was still installed.

It took my some time look from this side. :
After uninstalling XScreensaver and reboot my problem was gone.

Just I pitty that I could not find an adequate alternative for XScreensaver under Wayland so far.
