How To Configure Itch.io App For HiDPI Displays on Linux
- Adam Douglas
I decided recently to explore the itch.io app that I’ve been reading about lately. I quickly installed the application via the AUR repository under the package name “itch”. I found out quickly that the app doesn’t handle HiDPI (high dots per inch) displays well. So I started to explore the settings and found nothing. I assumed that the app maybe Chrome / Chromium based and if not Electron based. I tried the to create the following files to see if the itch.io app would recognize the config flag I set.
Each file contains the following.
Unfortunately none of these files had any affect on the itch.io app. After doing some further research into the problem I confirmed that itch.io app is Electron based.
Here is how I resolved the problem.
- Arch Linux x86_64 kernel 5.13.4-arch1-1
- BASH v5.1.8(1)
- GNOME Shell v40.3.0
- GDM v40.0
- itch.io app v25.5.1 / v1.26.0
- WaylandEnable=false (disabled in /etc/gdm/custom.conf)
- ~ (tilde) represents the $HOME (/home/username) of the current user when using BASH
- Steps prefixed with a “$” (dollar sign) represents the CLI (command-line interface) prompt
- Steps prefixed with a “#” (number sign) represents the CLI prompt with elevated user permissions (e.g. root)
- The text after the “$” or “#” is to be entered at the CLI
The itch.io app doesn’t appear to have a setting via the graphical user interface (GUI) to adjust the DPI scale when used on a HiDPI display.
The scale value of 2 shown below can be changed to what is personally desired. Floating point values can be used (e.g. 1.75).
Solution / One (recommended)
Create a desktop entry file per user basis to override the system wide desktop entry file as follows.
1 $ nano ~/.local/share/applications/io.itch.itch.desktop
1 2 3 4 5 6 7 8 9 10 11 [Desktop Entry] Type=Application Name=itch TryExec=itch Exec=itch --force-device-scale-factor=2 %U Icon=itch Terminal=false Categories=Game; MimeType=x-scheme-handler/itchio;x-scheme-handler/itch; X-GNOME-Autostart-enabled=true Comment=Install and play itch.io games easily
Solution / Two
Edit the system wide desktop entry file.
1 # nano /usr/share/applications/io.itch.itch.desktop
1 Exec=itch --force-device-scale-factor=2 %U
Application updates will overwrite the desktop entry file.
