Three monitors support of Garuda

mvd · 22 April 2023 07:25

Hi there,
I've been trying a lot of diff distros and finally came to Garuda which became instant favourite!
Thanks to all who created it and support it!

I am having this multiple (3) monitor problem with Garuda.
Whenever I switch to the dock station my laptop with Garuda (which is conn. to other two monitors), all monitors take the not very high resolution of the laptop HW. Thus I cannot use the original high resolution capabilities of the other two monitors and the pictures and symbols are unnatural on those two.
I tried a lot of diff approaches to solve the problem incl. all kind of xrandr manual adjustments as described in diff video tutorials but finally i could not solve the problem.
I'd be very happy if Garuda team has a solution to fix this as I don't want to move to Fedora for which I know this problem is solved.
Thanks in advance and pls let me help you with this in case you need more constructive details.

God speed!

Many differences are not helpful, we need details and post the Garuda-Inxi with all monitors connected, please.
Did you use the system settings?

Unfortunately, I do not know if AMD has a settings app like Nvidia.

At least restart the PC, it's KDE

mvd · 22 April 2023 08:47

Thank you she-user!
I am a male if this make any diff for you.

I'll come with more responses later on...

SGS · 22 April 2023 08:50

Sorry, copy and paste error from my translation program

filo · 22 April 2023 11:37

I've never used multi monitor, but I think you could work on the xorg conf with e g. monitor conf file to set appropriate DPI for each external monitor. See:
https://wiki.archlinux.org/title/Xorg#Display_size_and_DPI
An interesting post here, including the solution of that topic:

mvd · 22 April 2023 14:42

OK, thanks (KDE is good; with Garuda it feels much better than other ditros with the Dwarf).
Here is the inxi with 3 monitors connected.
I am gonna display the screenshot of the Displ. conf and the monitors below. On it you can see that the 34"curved is set properly with XRANDR to its max resolution but it still is displayed with the laptops ('low') resolution).
The settings of the 27" monitor max resolution disappeared with the time but they shouldn't be relevant for the example. Unless someone request it...
Pls let me know if anything else I can present useful.
Thanks again

There is something wrong here.
Same for monitor-2.
I'd try with the xorg conf as per Arch Wiki.

mvd · 27 April 2023 11:22

So far not success.

I remember that I used cvt and xrandr to put the resolution of the biggest display in it and that's why i see 3440x1440 for the curved one here: /etc/X11/xorg.conf.d/10-monitor.conf
When the system is started i see it as an option (as displayed above in scr) but choosing it does not help to use it.
I am wondering what else I can do...
Is it a problem of Garuda which was not installed with these two additional monitors on first place, and without easy way to auto reconfigure or not easy to manually reconfigure the monitors with proper resolutions after installation of the OS,
or is is a problem of the AMD drivers, etc?
Are there users that can report the same problem with 2 or 3 monitors connected to the system, and how they solved the problem?

I don't have the problem (also, I use Wayland with Sway), but I would bet on the physical size thing as pointed out by @filo.
It may be the case it needs fixing the EDID, but I have totally zero knowledge to share, just a search string: linux fix wrong edid from monitor - Whoogle Search -- This result looks promising.

In my case, edid-decode reports

  Basic Display Parameters & Features:
    Digital display
    Maximum image size: 70 cm x 39 cm

for the external HDMI monitor (actually, an old TV) which is correct.

mvd · 27 April 2023 13:58

Do you mean the resolution size of the monitors are too big and not provisioned by Garuda team?
When I set the resolution to max i have message on the monitor conf box that:

"gaps betwen displays are not supported. make sure all displays are touching"

what practically this means?

Do you mean the resolution size of the monitors are too big and not provisioned by Garuda team?

No, I mean the detected physical size (size: 160x90mm) is too small, and I suspect it could be something with the EDID information returned by the monitor to the OS (of course, my theory may well be wrong).
If decode-edid returns the correct size, it means I'm wrong.

"gaps betwen displays are not supported. make sure all displays are touching"

just means that, in a multi-monitor configuration they should all be contiguous, where one monitor ends the next pixel is on the neighboring other monitor without space in between, like

+----+--------+
| M1 |   M2   |   # OK
+----+--------+

+----+  +--------+
| M1 |  |   M2   |   # NOT OK
+----+  +--------+

I don't know if this is Xorg limitation, as I said I use Wayland, and I can leave a gap between my monitors without problem (it's useful for CAD and games, to restrict the mouse on one screen, but I digressed).

edit: Reading again your last sentence ("When I set the resolution to max"), I also suspect the error message is imprecise, and likely the two overlap rather than have a gap between.
Let's say I have the "OK" setup above, and now I increase M1 resolution, I'd also have to move M2 to the right.

mvd · 3 May 2023 05:53

thank you for the contemplation on the issue!
I set the resol. of Curved (right upper one) to the max and move the monitor 1 (left upper one) so they all are touching perfectly. Then i 'apply' and nothing changes in the montor virtual positions or the resolutions (all are back to 1920x1080)

mvd · 5 May 2023 09:01

So far, a partial success with a lot of manual play and a workaround.
The support of 3 monitors is not OK in Garuda linux as of now.

I tried diff ways to connect the monitors and the one where i connect 27" through HDMI, and 34" through docking station (usb type-c) worked partially.
34'' is set to its max resolution now (3440x1440), but 27'' has chosen a bigger (2560x1440) but not its max resolution (which i am not sure where it took it from). so 3840x2160 is not appearing at all in the display settings. Why?

the content of 10-monitor.conf is:
