 - **feat: GNOME support (the "SteamOS theme for GNOME" option, GDM session switching, the GNOME launcher/notifier/tray behaviour): the Vapor colors, the Steam Deck wallpaper, Ubuntu Dock, Tiling Assistant, Desktop Icons NG, AppIndicator and Steamify's own Vapor shell extension, with Switch to Desktop remembering KDE or GNOME. Prototype work since 2.12.0: `5dfc916`, `fc28ea4`, `ae12c1b`, `2b84e6a`, `c5b59d9`, `62a30e6`, `039f269`, `12eb562`, `c7f5f51`, `7904833`, `ce1aa1b`, `ab3b581`, `eaa3f28`, `4221ae6`, `8432f63`, `09ef0b1`, `68342e7`, `0e0bf57`, `7a84b0d`, `dbaeaa1`**
 - `2ca288d` **fix: the NVIDIA gaming mode setup no longer fails with "the patched gamescope doesn't start" on a gamescope that works: the smoke test judged gamescope's exit status through a pipe into `grep -q` under `pipefail`, so gamescope's crash on the closed pipe (or a hung shutdown) counted as a failed test, intermittently, for the CPU-specific and the generic build alike (seen on an RTX 5080). The test now reads gamescope's output from a file and kills a hung shutdown (`timeout -k`)**
 - `645b331` **feat: the GNOME theme installs GNOME Settings with the "GNOME Desktop" panel (dock, desktop icons, tiling) as a prebuilt package, downloaded from the `settings` release of steamify-gnome-theme (built by GitHub Actions on current Arch, rebuilt weekly) and checked against its `.sha256`; a failure keeps the stock Settings. Turning the theme off puts the stock `gnome-control-center` back. Installs with the GNOME theme on re-apply it (feature version 2.13.0)**
+- **fix: the app's logo (an SVG) shows on a fresh install: `pyside6` doesn't depend on `qt6-svg`, Qt's SVG plugin, so without it the header logo was empty and the window had no icon of its own; it is installed with PySide6 (the app's installer, the launcher, the update notifier)**
+- **fix: the app's icon shows in GNOME's dock on a fresh install: GNOME couldn't draw the SVG (a blank icon: "Could not load a pixbuf from icon theme"), by path or by name. The app's installer and the launcher put a 256x256 PNG (`assets/steam-gaming-settings.png`, a release file next to the SVG) in the user's icon theme and the launchers refer to it by name; the SVG stays as the fallback for releases without the PNG**
 
 - **feat: after the GNOME theme is applied in a GNOME session, the app's done screen has "Restart GNOME" (GNOME Shell on Wayland can't restart in place, and the dock, extensions and Settings panel only show after a new login): with GDM autologin (the SteamOS conversion) Steamify's relogin helper logs the user straight back into the session they were in (without changing the session gaming mode's boot goes back to), else it is a plain logout (`gnome-session-quit`)**
 - **fix: the app on a desktop (a window, however large, also fullscreen) keeps the desktop's own scale instead of blowing its 1280x720 layout up to the screen's height (twice as big on a 1440p or ultrawide monitor): the layout fills the window at the scale of GNOME or KDE, and only a window smaller than 1280x720 shrinks it. The TV mode (`--fullscreen`, gamescope) still scales to the screen**
 - **fix: in the app a click on a row only selects it (a second click on the selected row used to flip it, so a click on a switch needed two); a click on the switch itself, or on the BIOS update button, acts at once and selects the row too**
+- **feat: a run that only needs a new GNOME login (the theme, no reboot) ends with a countdown on the done screen ("Restarting GNOME in 10 s", with Restart GNOME now and Cancel) and then logs in again by itself, the counterpart of KDE restarting plasmashell (GNOME Shell on Wayland is the compositor too and can't restart in place). A run that needs a reboot keeps "Restart now" (it loads GNOME fresh): before, the Restart GNOME button was hidden then, and nothing started by itself**
+- **fix: Restart GNOME logs in to GNOME: after the SteamOS conversion the account's session is gaming mode, and the relogin went there (a restart that took a minute: Steam starting in gaming mode). `steamify-gdm-relogin` takes the session to log in to (the one the app runs in) for this login only and puts the account's session, the one the next boot goes to, back once the new session is up**
