Hello all,

KUbuntu 21.04

xlsclients command shows Opera running on Xwayland emulation, not native Wayland.

snap connections opera shows:
...
wayland opera:wayland :wayland -
x11 opera:x11 :x11

Googled for a while, but did not find any info on weather Opera even supports Wayland? Opera help web site does not even mention it...

So:

1. Is Wayland supported? (native Wayland, of course - not XWayland emulation)
2. How to enable it?

Thanks,
Andrej

@karbonat - Question is about >>Opera<< support for Wayland.

Not how to enable Wayland as such. Which I of course already did, and should be obvious from my post.

Thanks,
Andrej.

More and more people are running Wayland and Firefox supports Wayland without the X compatibility layer.

Running opera-developer 79.0.4135.0 I get:

[1359809:1359809:0803/164440.133269:ERROR:browser_main_loop.cc(1409)] Unable to open X display.

@webninja Opera is based on Chromium; as such, it will have Wayland support when Chrome does. Firefox is not based on Chromium and can do what they want in that regard.

It seems Opera does support wayland perfectly fine, you can execute it as such:

opera --enable-features=UseOzonePlatform --ozone-platform=wayland %U

Though it seems when editing opera.desktop it doesn't has the desired effect, put this here ~/.local/share/applications/opera.desktop:

[Desktop Entry]
Version=1.0
Name=Opera
GenericName=Web browser
Comment=Fast and secure web browser
TryExec=opera
Exec=opera --enable-features=UseOzonePlatform --ozone-platform=wayland %U
Terminal=false
Icon=opera
Type=Application
Categories=Network;WebBrowser;
MimeType=text/html;text/xml;application/xhtml_xml;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;application/x-opera-download;
Actions=new-window;new-private-window;

[Desktop Action new-window]
Name=New Window
Exec=opera --new-window --enable-features=UseOzonePlatform --ozone-platform=wayland
TargetEnvironment=Unity

[Desktop Action new-private-window]
Name=New Private Window
Exec=opera --incognito --enable-features=UseOzonePlatform --ozone-platform=wayland
TargetEnvironment=Unity

Hope that helps!

@gigol Recent update to Chromium fixed this.

Set this flag to "Wayland".

[opera://flags/#ozone-platform-hint]

If for whatever reason your Opera session runs under XWayland (the nested X11 server for Wayland), set the (opera://flags/#ozone-platform-hint) flag to "Wayland."

Opera does not seem to detect the Wayland Display on the other hand chromium works just fine.
