+title: Useful KDE window rules
+excerpt:
+  KDE Window rules (kwin?) are very helpful when windows just don't align to
+  your wishes, especially on small displays like Steam Deck or when your games
+  launch positioned wrong or your gamescope fullscreen flag just gets ignored.

+
+First step is opening `systemsettings`, scrolling down to `Apps & Windows` where
+there is `Window Management` which opens a sidebar with `Window Rules`.
+
+Alternatively one can just second click any titlebar, choose ore
+actions`and select either`Window specific special settings`or`App specific
+special settings` (backtranslated from Finnish).

+## Gamescope
+
+My first papercut that I thought for a longer time on Fedora Kinoite (instead of
+SteamOS) on Steam Deck was that my games with Heroic Launcher were focusing
+wrong, partially across the screen. A few times I just double clicked the
+titlebar to maximize it, but then I realized I can right click the window,
+select the more actions and make rules for the window. Of course the add rule
+from `systemsettings` would work too.
+
+- Description: `settings for gamescope`
+- Windows class (application): `Exact match`: `gamescope`
+- Match whole window class: `Yes`
+- Window types: `All selected`
+- Size & Position: Add Property
+  - Initial placement: `Force` `Maximized`
+    - _Originally I went just with this, but then I realized that I can fix
+      gamescope ignoring `--fullscreen` flag with the next property:_
+  - `Fullscreen`: `Apply initially`
+
+**_TODO_**: The _Add Property_ sections above are wrong since they were
+automatically filled for me and thus I wrote them wrong, while it's easy to
+figure out what I mean.
+
+## All apps
+
+My Steam Deck has a small display and I generally use it docked to TV, so why
+not maximize everything by another rule?
+
+- Description: `everything?`
+- Windows class (application): `Unimportant`: ``
+- Match whole window class: `Yes`
+- Window types: `Normal window`
+- Size & Position: Add Property
+  - Initial placement: `Force` `Maximized`
+
+**_TODO_**: The _Add Property_ sections above are wrong since they were
+automatically filled for me and thus I wrote them wrong, while it's easy to
+figure out what I mean.
+
+And there is one papercut less on enjoying Fedora Kinoite on Steam Deck. I think
+this would also work with SteamOS, but that launches to game mode aka big
+display mode anyway, so it's unnecessary.
+
+Offtopic lifehack:
+
+```bash
+mkdir -p ~/.config/autostart/
+ln -nsfv /var/lib/flatpak/exports/share/applications/com.heroicgameslauncher.hgl.desktop ~/.config/autostart/
+ln -nsfv /var/lib/flatpak/exports/share/applications/com.valvesoftware.Steam.desktop ~/.config/autostart/
+```
+
+Next login you will autostart Heroic Games and Steam. I suggest visiting Heroic
+Games settings to start minimized so it will background update games and Steam
+settings to start in big picture mode, so you will have Steam Deck like
+experience even without SteamOS.
+
+With Heroic Games your mileage may vary as some games want minimizing Steam for
+controller to work, others want Steam to be quit.
+
+## FanFicFare
+
+Funnily this is the first window rule I remember making on my main laptop
+regarding FFF's browser cache feature.
+
+- Description: `Calibre FFF on top`
+- Windows class (application): `Unimportant`: ``
+- Match whole window class: `Yes`
+- Window types: `Normal window`
+- _Add Property_
+- Window title: `Exact match`: `Downloading metadata for stories`
+- _Add Property_, _Arrangement & Access_
+- Keep above other windows: `Force` `Yes`
+
+## GNOME Console
+
+I don't remember making these settings, but they seem to be working?
+
+- Description: `Preferences for org.gnome.Console`
+- Windows class (application): `Exact match`: `kgx org.gnome.Console`
+- Match whole window class: `Yes`
+- Window types: `All selected`
+- _Add Property_ _Size & Position_
+- Position: `Apply initially`: `768` x `432`
+- _Add Property_, _Size & Position_
+- Size: `Apply initially`: `768` x `432`
+
+And my GNOME Console aka `kgx` launches on bottom right of the display.
