Color Palette Button Causes a Freeze Up
19 November, 2024 - 23:26 — Thomas Henry
Hello,
Before I forget, here's another anomaly I noticed recently. When using Qtractor 1.4.0 (installed from the PPA), if I try to access a color palette button, the entire program freezes (locks up).
Both the color palette buttons in the Track setup menu and in the View/Options/Display menu cause Qtractor to freeze when clicked.
On the other hand, they work properly in the AppImage for 1.4.0-6.1, and also in version 0.9.39 found in Linux Mint's Software Manager.
By the way, my op-system is Linux Mint Xfce 22.

re. Color Palette Button Causes a Freeze Up...
hi, this is an old environmental issue, making its come back now and then, especially on Gtk based desktops.
try switching off the "Use desktop environment native dialogs" in View/Options.../Display/Options, and/or ultimately chose a custom widget "Style theme", any other than "(default)" and avoid "Gtk" at all costs! "Fusion" is an all-time favorite here :).
hth. cheers
Other posible solution

I had the same problem.
In my case I found another solution.
I uninstalled a conflicting library, but I forgot which one.
It's a problem between inappropriate combinations of Gtk and Qt libraries, there's no doubt about that.
Thanks for the suggestions
Thanks to both of you for the ideas to try out. It's still acting up, and so I'm just trying to train myself to avoid the palette buttons.
The trade-offs now stand at:
Use the AppImage. Then there is no freeze-up on the palette buttons. On the other hand, then I don't get the advantage of the GUIs for the various cool plugins (like Calf).
Or, use the installed version. Now I get the nice GUIs for plugins, but need to avoid the palette buttons.
Given the choice, the latter seems the better of the two since I'm too much of a Linux novice to know what Gtk even is.

Does this happen on Mint with Cinnamon desktop?
You mentioned that you had another machine with Cinnamon.
Could you check if it happens there?
I want to move to Debian 12. I've tried it with Xfce... and that annoying bug has appeared again.
Maybe the solution is to change desktop system.
I would be annoyed, because Xfce fits me very well.
Okay on Cinnamon
Greetings,
I checked it out, and the palette buttons work just fine on Cinnamon 20.3 running on my better day-to-day computer.
Cinnamon would have been my first choice for the studio computer. However, that particular machine has rather limited resources so I was forced to go with Xfce, which works quite well in general. This is an older computer with only 4 gig of RAM possible, and a dual core CPU. It was an old junker destined for the landfill, but as it turns out, is eminently usable for MIDI sequencing.

LXQT desktop doesn't give the error
I've tried the LXQT desktop and it doesn't give the error.
It's based on QT like Qtractor.
I hadn't tried it before, and it seems to be on par with XFCE. At least my first impressions.
It's even easier and more effective to customize.
When you log in you can select whether you want XFCE or LXQT.
If you have enabled the OS to load without "Login Screen", you'll need to log out. That sends you to the login screen. There you change (select) the desktop system.
The only drawback: it will install applications equivalent to those you already have in XFCE.
You will have for example 2 file managers:
- Thunar (xfce)
- PcManFM-Qt (LXFCE)
I can't guarantee that it's a solution for Mint either (I've tested it on debian 12), but everything seems to indicate that it is.
If you want to try it, to install it:
sudo apt-install lxqt
