Windows move to secondary display after waking from power save mode

[edkirin]

I have two display setup on my desktop rig. Primary LG 4k and secondary Samsung. When computer wakes up from power save mode, all windows from primary are moved to secondary display. It’s pretty annoying X times a day to move 10+ windows back from secondary to primary display and position it where they belong.

It seems that it takes a split second longer for primary display to turn on than secondary, so I guess that OS thinks primary is disconnected and moves all windows to secondary. This is a new LG display I bought few weeks ago and it’s driving me nuts.

I tried changing DP/HDMI ports for both displays, but it didn’t help.

Any idea how can I fix it? I know I can turn power saving off, but I don’t even consider this option.

Thanks!

From BIOS post to GRUB the dGPU aka PEG aka PCIE will have a order to activate the ports like this
VGA > DVI-I > DVI-D > HDMI > Displayport

So, in your case

@edkirin

Monitor-1: DP-0

that DP is Displayport - will activate after

@edkirin

Monitor-2: HDMI-1

You could eventually try to create a fixed Layout from Nvidia X Server Settings and append that modified information in /etc/X11/mhwd.d/nvidia.conf and also change the "nvidiaXineramaInfoOrder" port in the Section "Screen", but still not sure that will help very much.
This is how i always set it on my end, maybe the example will help you:

Thanks for suggestion. I have actually two configs related to x11:

• /etc/X11/xorg.conf
• /etc/X11/mhwd.d/nvidia.conf

Also, I have nvidia-settings utility which is writting config to /etc/X11/xorg.conf. I set config using this utility similar to yours. As far as I understand, manjaro uses the latter config file, so I linked /etc/X11/xorg.conf to /etc/X11/mhwd.d/nvidia.conf.

I’ll see if it will be better with new config.

[anon89812132]

@edkirin

/etc/X11/xorg.conf

That needs to be removed.
MHWD creates the default config in /etc/X11/mhwd.d/nvidia.conf as i already mentioned. The only symlink required and present should be /etc/X11/xorg.conf.d/90-mhwd.conf that points to the /etc/X11/mhwd.d/nvidia.conf

Then to make sure things are correct, you run:

sudo mhwd-gpu --setmod nvidia --setxorg /etc/X11/mhwd.d/nvidia.conf

[edkirin]

Thanks for all the help. I will let you know if it solved the problem.

[dextertd]

I also face this problem, would love to see a working solution too.

Related: in the past I faced a similar problem where my entire desktop (panels and backgrounds included) would swap between my two external monitors, but I can’t seem to reproduce that anymore. Unfortunately there was no solution at the time.

[edkirin]

Unfortunately, it didn’t help.

[anon89812132]

Can you share the content of /etc/X11/mhwd.d/nvidia.conf
Also, did you set early KMS ? Skip the first part from here, and just do the /etc/mkinitcpio.conf part

Switching to Nvidia drivers from Nouveau with mhwd fails

sudo mhwd -r pci video-linux then sudo mhwd -i pci video-nvidia On gnome you might have to enable early kms. As administrator edit the /etc/mkinitcpio.conf and make the MODULES= line like this MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm) then run from terminal: sudo mkinitcpio -P sudo update-grub Also, you probably have autologin on and is trying wayland session and not always starts (at least on my end does funky things)

[Olli_GT]

OK, moving my topic to an new one was surprising for me. I thing the problem is not graphic card relevant. It looks like a plasma problem for me.
But alright. Your will know more like I.

[anon89812132]

Please read the Forum Rules - Manjaro

Most likely is a KDE Plasma issue on some systems. Is not happening on mine, dual monitor and Nvidia GPU and KDE Plasma 5.24.6, so, till we can identify the exact issue, is better to keep things separate.

[edkirin]

Sorry for late reply.

Maybe is worth mentioning that I had another 4k display (benq) for like year or so instead of this new LG and I had no similar issues with it. As I wrote in my initial post, this is what I think it’s happening:

It seems that it takes a split second longer for primary display to turn on than secondary, so I guess that OS thinks primary is disconnected and moves all windows to secondary.

Here’s my configs:

Try DFP-0

@edkirin

I removed all commented lines

You only need to add to the modules if you enable early KMS, and is already explained

@Switching to Nvidia drivers from Nouveau with mhwd fails

edit the /etc/mkinitcpio.conf and make the MODULES= line like this

MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)

Now, with the latest mkinitcpio the entries are all between ( ) and not " " but still is not a big issue, because will work with both …

@edkirin

worth mentioning that I had another 4k display (benq) for like year or so instead of this new LG and I had no similar issues with it.

Well, if the LG is initiating slower than the Benq and your Samsung, then that might be an explanation, but i’m not 100% sure.

[edkirin]

Unfortunately, with all the modifications you suggested, no changes at all. Thanks for the effort, I guess I will need to wait for some general kwin fixes. I saw people a lot of users complaining on KDE with broken multi-display support.

[megalomaniakaal]

which monitor is connected to which output on the gpu? IIRC there’s some prioritized order to them. Note that I’m not talking about the order mentioned in second post of the topic. I’m talking about on HW Firmware level. See for an example:

EVGA FAQ - What's the priority for the output ports on my EVGA graphics card...

Note that it can also change depending on if you are using legacy bios system or UEFI.

@edkirin

I saw people a lot of users complaining on KDE with broken multi-display support.

Yeah, linux is in general pretty bad with this, but then windows isn’t perfect either.

[edkirin]

I finally fixed the problem by disabling deep sleep option on LG monitor.
