+name: CachyOS Workstation Setup
+description: Current workstation config - CachyOS on ASUS laptop, dual NVMe, autostart apps, old home btrfs subvolume location
+type: reference
+---
+
+## Workstation: acg-guru-5070
+
+- **OS:** CachyOS (Arch-based), kernel 6.19.x
+- **DE:** KDE Plasma 6 (Wayland)
+- **CPU/GPU:** Intel Arrow Lake-S + NVIDIA RTX 5070 Ti Mobile
+- **Tailscale IP:** 100.95.216.79
+
+### Storage
+- **nvme0n1:** 954GB btrfs - CachyOS install (OS, root)
+- **nvme1n1:** 954GB ext4 - `/home` (formatted from old Windows drive)
+- **Old home:** btrfs `@home` subvolume on nvme0n1, mount with: `sudo mount -o subvol=@home UUID=8a8b1d34-99fb-470f-82ca-b5d08e43ec32 /mnt/old-home`
+
+### Autostart Apps (~/.config/autostart/)
+- `arch-update-tray.desktop` (pre-existing)
+- `cachyos-hello.desktop` (pre-existing)
+- `discord.desktop` (added, starts minimized)
+- `tailscale-systray.desktop` (added)
+- ScreenConnect: autostart removed (on-demand only via URI scheme handler from web UI)
+
+### Known Issues
+- **Warm reboot hangs:** Rebooting (e.g. for GPU issues) causes system to hang with spinning symbol — requires hard power-off. Observed multiple times. Likely NVIDIA driver not unloading cleanly during shutdown.
+
+### Key Fixes Applied
+- **Tailscale:** `--accept-routes`, systemd-resolved + NetworkManager DNS config
+- **Brightness:** Hide nvidia_0 backlight via udev rule, KDE controls intel_backlight only
+- **ScreenConnect:** dpkg + full JRE + Wayland patch (GDK_BACKEND=x11)
+- **Sudo:** NOPASSWD for guru user
+
+**How to apply:** Reference when troubleshooting workstation issues or setting up additional services.
