DT 5 Vectorscope Locking App

Just wondering if anyone else is having a problem with DT 5 locking up when the waveform is selected. It’s happened every time I’ve selected the waveform display and requires force closing DT. Wasn’t a problem in 4.8.

I’m using Linux Mint / Intel CPU / Nvidia RTX 3060. Open CL selected.

Apologies - just made a big mistake.

It is the Vectorscope that is not working correctly - it either does not appear or locks DT up.

Waveform is working fine.

You will need to provide a logfile to help troubleshoot the problem. flatpak? Snap? Self compiled? Does it happen with opencl off?

Self compiled from darktable.org download. I will do some testing - I have another version on my laptop.

Could not reproduce. Built from sources, though I use Fedora 31 and AMD Radeon RX6600 (OpenCL is enabled)

I think the problem is unique to my desktop build - it does not happen on my laptop. It is not the end of the world so I will just wait for 5.0.1 to come out and reinstall darktable and see what happens. In the meantime thanks for taking the time to check it out and respond.

edit to add that the lockup problem is no longer occurring but the vectorscope simply does not appear

Please provide a log.

I have tried everything I can find to start from terminal including ‘darktable -d common’ and ‘darktable-cli’ but always get the following error:

Command ‘darktable-cli’ not found, but can be installed with: sudo apt install darktable

I suspect this has something to do with not using the darktable supplied with Mint 22 (which is only 4.6) and building from the source code on the darktable.org site.

This may be self inflicted since I have not launched darktable from terminal previously.

Where did you put your self installed binary? Go to that folder and issue the terminal command.

The binary is in /opt/darktable/bin and I have tried running from there - get the same error message.

This what the folder structure looks like

Either run
/opt/darktable/bin/darktable -d
Or go to that directory, and run
./darktable -d

On Linux, for sake of security, the current directory is not on the path (won’t be checked for executable programs). This way, you only run the system’s trusted (packaged or administrator-installed) software, unless you explicitly state otherwise.

If I run

/opt/darktable/bin/darktable -d

a document (manual) appears.

If I run

/opt/darktable/bin/darktable -d all

I get output that seems to go on forever. I tried to copy and paste the output but was unable.

Send the output to a file.

any-linux-command > /tmp/some-log-file.txt 2>&1

The -d requires a parameter. Use -d common, as others have suggested.

The ‘…’ in my response was supposed to mean you should continue the command as the others have suggested.

OK here is the log file with -d all. If you would prefer with -d common let me know.

FWIW I was only able to launch darktable from the terminal when attempting from the root using /opt/darktable/bin/darktable -d all. If I tried to launch darktable by first going to the /opt/darktable/bin directory I would get the command darktable not found…

I’ve already explained that. You need ./some-program-in-current-directory. That ./ is needed.
