Screen settings keep changing back to default

[Karl.S (Karl Schoelpple)]

Hi,
using 0.9.24 on a Ubuntu 20.04 machine with a screen resolution of 1920x1080 I adjust screen settings and layout to suit my needs.
However, every time I restart Lightburn I find it reverts back to default display settings and I have to start all over again.
Checked the various settings and options.
Is there a way to save my settings so Lightburn always starts the same way ?
Thanks!

The only time we’ve seen it do this is if there isn’t enough room for the display layout chosen. Check to see if that’s a possibility here - giveaway is the tabs for the laser / Cuts&Layers / etc windows being scrunched up.

You can force a particular screen size using a script and wmctrl. See:

Window Sizing bug in Linux [Workaround]

Latest LightBurn for Linux, Running on Lubuntu 18.04, Window size doesn’t stay with last settings (keeps resizing on each new start to a size larger than my screen) although Prefs.ini has the window size values appearing to be correct. Note: My screen is low resolution (1366x768) because I’m using a touchscreen but I can layout the tool windows to fit nicely in a single group. This works well on my MiniPC with Windows 10, doesn’t work on Linux. I’ve attached my prefs.ini in case that helps. …

The Laser tab appears to be fine - see screenshot.

However, had to place an earlier post on here as I could never find the colour bar and then discovered it being hidden behind my taskbar - hence always have to re-arrange the layout to suit.

Resolution is 1920x1080
Also just checked to ensure it is standard resolution - not enlarged, as I know that can sometimes cause problems.

Happy to report I finally found a fix / workaround:
(This applies to KDE plasma screen on Kubuntu and hence may not work for every Linux flavour)

• By right-clicking on the top titlebar, then selecting “More Actions” followed by “Configure Special Window Settings” you’ll get a special menu.
• Pick the “Size & Position” tab
• Select “Size” and option “Force” then enter a suitable value for your particular screen resolution.
  ( you may have to try different settings)
• Click on “OK” and you’re done.

…I had a little bonus surprise as I suddenly got a pointer location indicator on the bottom left corner which I never had before.

Follow up: After further testing and actual use with Laser I’ve made the following observation:
With above mentioned method the initial screen is fine. However, when loading a file the screen is refreshed and it reverts back to original settings. → Fix for this is to select “Special Application Settings” in above mentioned menu, rather than the Window Settings.
Unfortunately this results in all sub-windows displayed within Lightburn reverting to your custom screen size. I.e. opening the Machine Settings will be full size as well.
I still prefer this to not having all components of screen displayed as it was before.
