Can't get obs-studio working on Wayland

olividir · August 7, 2023, 9:10pm

First of all, I am using obs from extra channel (not git from AUR).

When I run obs in terminal I get

[olividir@ProX15 ~]$ obs
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vkkhrdisplay, vnc, xcb.

Aborted (core dumped)

I found this solution on the forum and installed xdg-desktop-portal-gnome, but I still get the exact same results as above:

Lastly I tried to do export QT_QPA_PLATFORM=wayland which does nothing in my case.

Now OBS should have Wayland support since version 27 (current is 29) so I am not sure why this is going so badly for me.

If someone knows what I am doing wrong, I would love to know it.

Try:

QT_QPA_PLATFORM=xcb obs

olividir · August 7, 2023, 9:14pm

Well, that got OBS starting.

Do I need to make this permanent?

Edit*
I keep getting “OBS is not responding, do you want to wait or force it to stop” notification. Maybe a different thread?

xircon · August 7, 2023, 9:25pm

Yes, edit the desktop file and change the exec line.

olividir · August 7, 2023, 9:31pm

Having slight problem remembering where that file is…will look in the arch wiki

Just so I am sure, we are talking about etc/profile file, correct? If so, I am not able to find the exec line.

I tried to do

export  QT_QPA_PLATFORM=xcb obs

to add it to bash_profile but it didn’t take

olividir · August 7, 2023, 10:20pm

Ok, I have been reading the arch wiki, all the desktop files I find are all wrong locations.

In etc/profile, /etc/bash.bashrc, /usr/share/bash-completion/bash_completion, ./bashrc and ./bash_profile. None of them have the line QT_QPA_PLATFORM= and I am currently confused where I should make this change

However, if I check all exported changes (export -p), I am able to find the line QT_QPA_PLATFORM=xcb. I am super confused.

GolDNenex · August 7, 2023, 10:39pm

On Plasma, I put it in ~/.bashrc at the end:

QT_QPA_PLATFORM="wayland,xcb"

olividir · August 7, 2023, 10:44pm

I already tried putting QT_QPA_PLATFORM=xcb obs in bashrc at the end, but it does not work… (I did sign out and back in).

This is a bit frustrating.

GolDNenex · August 7, 2023, 10:51pm

QT_QPA_PLATFORM=xcb obs

This command will launch obs with xwayland.

QT_QPA_PLATFORM=xcb is a environment variable in this context and obs is the app.

QT_QPA_PLATFORM="wayland,xcb" can be translated with "run my app with wayland and only if needed with xwayland.

If you want to try a change in ~/.bashrc, you simply open a new konsole or a new tab.

pebcak · August 8, 2023, 6:03am

If you still need to edit the Exec line in the .desktop file you could:

cp /usr/share/applications/com.obsproject.Studio.desktop ~/.local/share/applications/

and edit the file in the latter location.

HTH

olividir · August 8, 2023, 6:23am

I did exactly as you did @GolDNenex, adding QT_QPA_PLATFORM="wayland,xcb" in the last line of ./bashrc does not work for me. Have no idea why that is.

@pebcak I made a mistake, I changed the Exec=obs to Exec=xcb obs after cp /usr/share/applications/com.obsproject.Studio.desktop ~/.local/share/applications/

Should the Exect line be Exect=xcb,obs or somehow different…

Need to get going to work… this is something that can wait

pebcak · August 8, 2023, 6:44am

Try: Exec=env QT_QPA_PLATFORM=xcb obs and check if it will work.

xircon · August 8, 2023, 8:02am

Sorry for not explaining fully, had to get to bed What @pebcak said.

olividir · August 8, 2023, 5:37pm

That did the trick, now obs starts from desktop

Thank you all for your help

xircon · August 8, 2023, 5:44pm

When obs updates, it will overwrite the desktop file:

sudo chattr +i /usr/share/applications/com.obsproject.Studio.desktop

-i to make it mutable again

pebcak · August 8, 2023, 5:55pm

I think they made the change to the .desktop under user’s directory…

xircon · August 8, 2023, 6:05pm

Then I will get my coat

olividir · August 8, 2023, 6:06pm

So I should run this command now? Haven’t seen this command before, I will look through the wiki

pebcak · August 8, 2023, 6:08pm

No, not if you made the change to the file you copied to your home directory at /.local/share/applications.

olividir · August 8, 2023, 6:09pm

That’s what I did. When obs updates next and it doesn’t work, I think I could repeat the process of changing the exec line again
