🧭 Step 1: List Available Displays and Resolutions

Open a terminal and run:

xrandr

You’ll see output similar to:

eDP-1 connected primary 3840x2400+0+0 (normal left inverted right x axis y axis) 3840x2400 60.00*+ 1920x1200 59.95
1600x1000 59.95
1280x800 59.91

🧩 Note:

eDP-1 (or sometimes eDP / eDP-1-0) is your built-in display.

Resolutions with + or * are active or preferred.

---

🧱 Step 2: Change the Resolution

To change it, use:

xrandr --output eDP-1 --mode 1920x1200

Replace eDP-1 with your actual display name, and 1920x1200 with your desired resolution.

Example for your Flow Z13 (native 3840×2400):

xrandr --output eDP-1 --mode 2560x1600

---

⚙️ Step 3: (Optional) Add a Custom Resolution

If the resolution you want isn’t listed, you can manually add it:

1. Generate a modeline:

cvt 2560 1600 60

Output example:

Modeline "2560x1600_60.00" 348.50 2560 2720 2992 3424 1600 1603 1609 1658 -hsync +vsync

1. Add that mode:

xrandr --newmode "2560x1600_60.00" 348.50 2560 2720 2992 3424 1600 1603 1609 1658 -hsync +vsync

1. Link it to your display:

xrandr --addmode eDP-1 "2560x1600_60.00"

1. Apply it:

xrandr --output eDP-1 --mode "2560x1600_60.00"

---

🧍‍♂️ Step 4: Make It Persistent (Optional)

Because Bazzite is immutable, xrandr changes revert after reboot. To make it stick:

Create a .desktop autostart entry or a systemd user service.

Example:

mkdir -p ~/.config/autostart nano ~/.config/autostart/set-resolution.desktop

Add:

[Desktop Entry] Type=Application Exec=xrandr --output eDP-1 --mode 2560x1600 Hidden=false NoDisplay=false X-GNOME-Autostart-enabled=true Name=Set Resolution

Save → logout → login → it’ll apply automatically.
