Shotcut installed but wont execute

Help/How To
21

Ok so you’re right. The right driver version for my graphics card (GeForce 7050) is 304.137. That’s why the resolution freaked with 384. I’ve installed it ok i think, this happens…

$ lsmod | grep nvidia
nvidia 11407360 31
drm 352256 3 nvidia

now the shotcut boot says this…

~$ shotcut

[Debug ] <static ShotcutSettings& ShotcutSettings::singleton()> deinterlacer “onefield”
[Debug ] <static ShotcutSettings& ShotcutSettings::singleton()> external monitor “”

Then nothing happens. I don’t even get a command prompt

I’m using ubuntu studio Xenial Xerus 16.0.3 LTS 64bit

I suspect that your OpenGL libraries are either missing, out of date, or corrupted. Which pretty much covers 100% of what might be wrong without suggesting 1% of how to fix that. I did a search with Synaptic Package Manager and came up with too many hits on OpenGL.

Looking at your lsmod results, they looked surprisingly sparse. This is what I get back:
system@system-p6531p:~$ lsmod | grep nvidia
nvidia_uvm 667648 0
nvidia_drm 45056 4
nvidia_modeset 843776 7 nvidia_drm
nvidia 13119488 458 nvidia_modeset,nvidia_uvm
drm_kms_helper 167936 1 nvidia_drm
drm 356352 7 nvidia_drm,drm_kms_helper
system@system-p6531p:~$
I wonder if something in your Nvidia installation took a dive.

Unfortunately, at this point I’ve hit the wall. I’m reluctant(!!) to suggest a possible route to reinstall X11, I can’t identify what lib’s should be reinstalled or installed. I do know X11 and OpenGL should be present with any installation. That you have a GUI desktop says X11 is alive and (presumably) well. If feasable, you could try a fresh Ubuntu installation, and see how Shotcut behaves. This is very much a “throw the spaghetti at the wall, and see what sticks” approach. After that… ya got me.

I think you’re better off asking specifically why a launch fails with OpenGL errors.

snap is notorious for having a problem with the nvidia brinary driver for apps that need opengl. I have posted about this multiple times in this forum with links to bugs, etc. I am not going to keep repeating myself - search “snap nvidia” and look around.

Hi, i got the very same problem in Manjaro linux. Was able to solve it by removing mlt-git packages and installing mlt packages.

So try to install mlt packages again, hope it helps!

I literally just stumbled upon this myself. I wanted to use Shotcut to honestly convert H.264 to DNxHD for the free Davinci Resolve for editing on Ubuntu 18.04 LTS and basic edits. I already knew I couldn’t get it to work with the Ubuntu Studio. I didn’t know it was because of official drivers. I even tested it with my last reinstall on my “test” PC for all this. I have an AMD Radeon R9 380 in this system. Basic Ubunti 18.04 install Shotcut works. Once I do the full graphics install then poof it no longer loads. I am hoping that the Shotcut team can resolve this please??? Since this seems to be a problem on both AMD and NVIDIA graphics drivers? I do love this beautiful program you have made :slight_smile:
