[SOLVED]polkit authentification issue while Davinci resolve install...

ixey · 2023-12-27 07:31:30

I am trying to install Davinci, but there is a few problems I got.

I had "qt.qpa.plugin could not load the qt platform plugin xcb in even though it was found" problem, but solve it by changing "QT_QPA_PLATFORM=wayland" to "QT_QPA_PLATFORM=xcb" in "/etc/environment" file.

Now, I can run ./DaVinci_Resolve_18.6.4_Linux.run script. I got GUI, but after clicking "install" in that GUI, I got polkit "Authentification failed" issue.

If I run ./DaVinci_Resolve_18.6.4_Linux.run script with sudo, I got "qt.qpa.plugin could not load the qt platform plugin xcb in even though it was found" error. Again.

Can you help me to fix it?

Don't put "QT_QPA_PLATFORM" into /etc/environment itfp.

Output in terminal:

Mod note: Moving to AUR Issues.

What https://wiki.archlinux.org/title/Polkit … ion_agents do you have installed and are running?
The built-in password dialog on the console won't work this way, https://bbs.archlinux.org/viewtopic.php … 5#p2028455

Hm... thank you for replay. Seems I have no any agent. At least "pacman -Qe | grep polk" and "pacman -Qe | grep lx" didn't print anything.
"pgrep -af polkit-gnome" also pring nothing.

Do I need to install something from this list?

Yes. And possibly start it (idk whether they're all dbus activated)

ixey · 2023-12-28 11:18:17

Thank you. I have installed lxqt-policykit, type 'lxqt-policykit-agent' in console and run script in other terminal window. That's worked.

How can I make lxqt-policykit-agent run automatically when an authorization request is made in the future?

Where I need to put setup of "QT_QPA_PLATFORM" variable?

That would depend on the desktop and how you're starting it.

For `startx` add the line to ~/.xinitrc (before the `exec` line and with an ampersand at the end). If you're using a display manager (why?) then use a .desktop file in ~/.config/autostart/; see https://specifications.freedesktop.org/ … atest.html for more on this.

The package ships /etc/xdg/autostart/lxqt-policykit-agent.desktop which will be triggered by a lot of DEs anyway, so first make sure whether it already autostarts w/ your session.

Edit: Also please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Seems triggering not working.

I reboot my PC, then use "pkexec bash -l", thats does not work.
Next I run "lxqt-policykit-agent" in other terminal and tried "pkexec bash -l" again.

In this time I got GUI and be able to login as root.

So, how I can fix triggering?

What is your desktop and how are you starting it?

ixey · 2023-12-28 13:40:08

That is my laptop, I start it by pressing botton "power on" on its body. I shutdown that by writing "shutdown 0" in trminal. This time I restart it by "sudo reboot 0".

How exactly did you install archlinux?

ixey · 2023-12-28 13:54:35

I didn't. Somebody install it for me because, "that is the best Linux ever with a very large active community and well written documentation". I didn't mind, I like customizable systems, but I never had the time to advance study Linux's internal architecture.

Then you should ask "somebody" how you're starting the system.
Hint:

loginctl session-status

then then check the wiki on how autostarting things works with the environment that somebody™ installed for you works.
Also, just so you know, somebody did you an incredible disservice.

Arch Linux
