Bug 458191

Hi,

unfortunately krfb + wayland doesn't work for months now.

Please add a function to disable the share function pop up on start with krfb, the last issue with this function is the crash of the device, the desktop is block after select it, the screen freeze.

I forgot with the last post

KDE plasma version 5.26.3
KDE frameworks version 5.99.0
Qt version 5.15.7
kernel 5.15.78-1

krfb 22.08.3-1

I also had problems with this. Then I set different passwords for attended vs unattended access. If I use the password for unattended access it worked ok. Could you try that?

I think krfb for wayland is broken due to https://bugs.kde.org/show_bug.cgi?id=451086 
I could only get krfb working on KDE by using the xcb and X11

Hej Hej, 

Thanks for your message, and the tips.

The unattended access password is working, because I set krfb with the xcb !
Thanks a lot for your help, it works !

Unfortunately, I did a test with wayland activated on the shared device, krfb and the desktop environment crash when I select ok on the pop up "Select what to share"

I observe the same issue after updating from Kubuntu 23.04 (lunar, 4:22.12.3-0ubuntu1) to Kubuntu 23.10 (mantic, 4:23.08.1-0ubuntu1).
When using Wayland, with each start krfb needs local interaction to grant access to the screen and input devices, even if "Enable Unattended Access" is ticked.
Another way to put it is that "Enable Unattended Access" stays ticked but does effectively nothing (it does not enable unattended access).
This does not happen with X11.
This is a problem for remote machines without physical access.

 Hi,

Thanks for your report, you are welcome to confirm this issue on the new kde forum.

Hi,

KDE 6 is alive, congratulations to the dev !

So, I did a test with krfb on wayland, I have to confirm the share screen on the devices running krfb on Wayland.

I hope soon a solution :-)

I hope it will be helpfull to solve it :-)
