## Dual Steam Accounts (same PC, two monitors) Runs a second Steam instance as `player2` on HDMI-0, alongside your main session on DP-0. Both accounts play simultaneously with full GPU acceleration — no VT switching needed. ### One-time setup (fresh install) **1. Create the player2 user:** ```bash sudo useradd -m -G audio,video,input -s /bin/bash player2 sudo passwd player2 ``` **2. Install dependencies:** ```bash sudo pacman -S xorg-xhost ``` **3. Add passwordless sudoers rule** (allows launching Steam as player2 without a prompt): ```bash echo "kuhy ALL=(player2) NOPASSWD: /usr/bin/steam" | sudo tee /etc/sudoers.d/player2-steam sudo chmod 440 /etc/sudoers.d/player2-steam ``` **4. Symlink the script into PATH:** ```bash sudo ln -sf ~/testsAndMisc/linux_configuration/scripts/gaming/start-player2.sh /usr/local/bin/start-player2 ``` **5. Start the getty on tty2** (needed if LightDM autologin is configured, otherwise tty2 has no login prompt): ```bash sudo systemctl enable getty@tty2 ``` ### Usage ```bash start-player2 ``` A Steam window opens as `player2`. Drag it to HDMI-0 and log into the second account. Click whichever monitor you want to control — no switching needed. To stop: close the Steam window or `pkill -u player2 -f steam`. ### How it works - Steam is launched as `player2` via `sudo -H -u player2 steam` on `DISPLAY=:0` (your main X session). - Because `player2` has a separate home directory (`~/.local/share/Steam/`), the two Steam instances don't conflict — different PID locks, different configs, different accounts. - `xhost +local:` grants local users access to your X display. - Full GPU acceleration since there is no nesting — both instances hit the hardware directly. ### Monitor layout | Output | Resolution | Session | |--------|------------|--------------| | DP-0 | 3840×2160 | kuhy (main) | | HDMI-0 | 2560×1440 | player2 |
