Dear Maintainer,

when I change the display scale, it doesn't apply.
*Steps:*
- Right-click on the (Plasma) desktop
- «Display setting»
- Move the slider to get a higher value
- Apply

Nothing happens. I've discovered later that changes are applied with
time, when closing/opening apps, the session...
So it's impossible to set the correct value with the current behaviour.

PS: the bug has already been submited upstream and refused(cause
Debian Plasma being too old)

Hi Stephane,

we don't track bugs for downstreams of Debian here so please raise this issue to the Devuan bug tracker so they can analyse it.

If it turns out to be an issue in Debian too I'm OK having a bug here too, but I have no idea how much divergence they carry from the Debian packages.

I seem to remember there were some limitations on the X11 side wrt scaling and display features in general, so if you're currently not under a Wayland session could you try and reproduce this bug there ?


Happy hacking,

Hi, Reportbug under Devuan send automatically the bug to the right
maintener. If the receiver is Debian, it's on your side.
I believe it's under X
