Also bumps the 16 meta/requirements pins the freshness gate flagged (anthropic 1.5.0, numpy 2.5.3, pytest-randomly 5, flake8-bugbear 26.9.9, ruff 0.16.7, pyright 1.1.414, selenium 4.49.0, hypothesis 6.168.0, lxml 6.1.3, pipdeptree 4.2.5, the two types-* stubs) and Flutter 3.47.3 in meta/.fvmrc. One test still expected the pre-move ~/mcp-servers path. The pre-commit hook fed .zsh files to shfmt and shellcheck, neither of which parses zsh (SC2148/SC1071), so no zsh file could be committed since the hook was tightened on 2026-08-22; those now get `zsh -n` instead. The hook's own shfmt pass also staged its reformat of 8 shell files. CI_GREEN_SKIP because main is red on exactly the dependency-freshness finding this commit fixes, which is the documented use of that flag.

## 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 ~/src/testsAndMisc/linux_configuration/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 |
