I updated my machines to Linux Mint19.1 and though the overall performance improved I have issues with lightworks, I haven´t had before:

When I boot mint freshly and open lightworks things work ok at first. when I have it running for a while and do other stuff lightworks playback gets stuck and i cannot playback anymore really..

I know this is a VERY vague description and hard to analyse maybe , but maybe someone has similar issues? or no issues at all with 19.1? I m curious...

What does memory usage look like once Lightworks becomes sluggish?

cpu looks normal,

ram usage is 9.3 GB of 16 gb which is pretty high with nothing yet in the timeline I guess...

but now i tried several times: the memory does not always get up that high and the program gets stuck anyways, so hard to track it down to the memory.. also weird that i really have to restart the whole computer and not just the program...

edit: not entierly true: restarting the program seems to be sufficient

Looks rather like the audio stops working, hence everything grinds to a halt, hope that's a clue

Installation in a VM was quick and runs trouble free.

thank you fishmonger for the hints.

and yes there is a sound issue, that appeared with the update. when i stop jack/cadence it works!! i havent tracked down yet what exactly the problem is (btw is there a way to connect lightworks directly to jack now? i thought so but i cannot dial in anything in the audio preferences: I/O device is greyed out.. )

but works for me for now

After the update (maybe kernel update) your audio devices are probably enumerated in a different order, they're named differently, or PortAudio recognizes different audio device as the default one.

If you have OuputDeviceIndex or OutputDeviceName in ~/Lightworks/GlobalSettings.txt defined, you should change it according to a new values (number or name). If not, you can add something like this:

[PortAudio]
OutputDeviceName=default


where "default" can be a name of your device ("jack", probably).

You can find all names in ~/Lightworks/Logs/error.log file.

Hej this is a late reply

thanks for your hint Marcin!

I am not finding any GlobalSettings.txt file on my system. so should i create one? Where to i put it, in

home/username/Lightworks

or into the project space i chose in lightworks (which i got on another hard drive)

yes connecting directly to jack would be fantastic!

Hi,

The file GlobalSettings.txt doesn't exist by default. Create it next to the location of the license file(s) which is "~/Lightworks", another notation for "/home/<username>/Lightworks".

thanks Hugly,

I created a GlobalSettings.txt in ~/Lightworks with

[PortAudio]
OutputDeviceName=jack


is that correct like that?

Can't say. I don't use Jack audio. So far, I assumed that this is the way:

[PortAudio]
OutputDeviceIndex=X
Where X is the numeric value shown in error.log for Jack audio input.

One side note: Even when assigned correctly, virtual cables are always tricky stuff, Lightworks needs relaxed buffering to work properly.
