<![CDATA[Snap apps - Scaling]]>Hi,

I'm running UT (24.04-1.2) natively on a Volla Tablet (no dual boot).
I installed some snap apps like Gimp and LibreOffice. They work great with one exception:

The workspace scales to a normal size and works perfectly. But the menu bar as well as all menus around the work area (where you choose e.g. tools in Gimp or fonts or text styling in LibreOffice) are tiny and it's hard to work with.

I tried different UI settings from within the apps (like screen resolution in DPI from Gimp settings) without any effect.

I tried to tweak that with UT Tweak Tool without success.

I tried to run these apps from terminal with settings like

$ GDK_SCALE=2 GDK_DPI_SCCALE=0.75 snap run gimp

and

$ snap connect gimp:gtk-3-themes :gtk-3-themes

Also no success.

Is there any way to tweak this? Thank you!!!

But I thought I ask anyway. Nevertheless, thank you so much! Yet, that helped me a lot.

Sorry I don't know a way to scale UI elements with an environment variable.

$ GDK_DPI_SCALE=2 snap run gimp

did solve half of the problem. All fonts are accordingly bigger and very good to read. Thank you for this!

However, all Buttons with their symbols on them (e.g. tool selection, layer selection,...) stay tiny.
Is there way to tweak this, too?

Maybe the terminal output is any help?

 $ snap run gimp

@jojumaxx said:

GDK_SCALE=2 GDK_DPI_SCCALE=0.75

are you sure about this syntax ? try

GDK_DPI_SCALE=2
