Shotcut is not working in Xubuntu 18.04

[Pavel_Petukhov]

Hello!

I have fresh install of Xubuntu 18.04, and try to get Shotcut to work. I tried both snap install and archived zip, none are working. I tried to run executable file from archive, nothing happen either. Is there any way to make it work?

I had Kubuntu 18.04 installed before that, and archived zip worked fine (except I had some bug when copying filters - fade away timing would not set to default). Snap didn’t work either though. And yet before that, I had Ubuntu 17.10, snap was working fine.

I use Nvidia drivers if that matters.

Thanks.

Please run the Shotcut startup script from a command prompt and report the output messages. Be sure you are running the wrapper script (Shotcut.app/shotcut) and not the actual Shotcut executable.

Here is the output:

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, wayland-egl, wayland, xcb.

Reinstalling the application may fix this problem.

There you go. Install XCB.

It worked. Shotcut starts now. Thank you.

However, I have some issues with the interface.

The arrows are bigger than place holders, I didn’t have it in my kubuntu installation.
Is it possible to correct it?

Could be a DPI issue. Try the suggestions here:

Interface fonts way to small

Hi all, I already used the search function but found nothing relevant. I am not able to use shotcutapp because I simply can’t read the gui. It is way to small. Restarting the windowmanager or even the pc did not help in any way. I am using: Linux Mint 17.3 with Cinnamon (and Mate) Kernel 3.19.0-32-generic shotcut 16.10.01 Maybe interesting for you: [Info ] <Application::Application(int&, char**)> device pixel ratio = 3 [Debug ] ShotcutSettings::singleton language “de” [Debug ] Shot…

Program dont fit on tv screen

Program don’t Fit on my screen when i add time line and other windows they get out of screen and there is no way to adjust them to screen. I am using linux and tv as screen via hdmi cable. Everything else except this app fits correctly to screen.

Shotcut theming gone wrong

Hello, I am not sure where Shotcut gets its buttons and sizing info from, but it looks just wrong. Here is the interface that I get: [Imgur] Happens with all the 3 selectable themes. Tried changing the system theme, icon theme, window manager theme, but nothing seems to affect the appearance of Shotcut. Looks fine when I install it in a virtualbox though which leads me to believe that it grabs the button size and theme from somewhere in …

thanks, it fixed it. I just added

QT_AUTO_SCREEN_SCALE_FACTOR=0

before

bin/shotcut “$@”

in …/Shotcut/Shotcut.app/shotcut and it did the trick.
