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.
