From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Launching gtk apps with scaling for HiDPI laptop. (lemm.ee)

I've just got a new laptop with a high resolution display and am having some trouble with scaling, particularly audio plugin GUIs which cannot be resized in Ardour (audio workstation) and are consequently too small to use. In the past I have launched qt apps via a script with something like 'packagename QT_SCALE_FACTOR=1.5’ (I don't have the exact command to hand).

Can individual gtk apps also be launched in this way? Is this a valid approach to the problem?

I'm using GNOME on Fedora 41 and an Intel Arc iGPU.

If you're using X, then the GTK equivalent environment variable is GDK_SCALE. (I don't think the Wayland backend does this though)

E.g. GDK_SCALE=2 gedit
