🚀 Turned an old Lenovo G550 laptop (with a broken screen) into a fully functional home-based personal cloud server using Linux Mint XFCE and Nextcloud.
🌍 Accessible over local Wi-Fi and ready for DuckDNS-based global access.
Family members often face storage issues on their phones, and cloud services like Google Drive have limitations or privacy concerns. The goal was to repurpose an old, low-spec laptop into a self-hosted, reliable, and secure cloud server — accessible from both mobile and desktop, and usable even without a working built-in display.
- Build a 24/7 file and media cloud server on old hardware
- Enable mobile-to-server file sync (like Google Photos/Drive)
- Make the server remotely accessible (via DuckDNS and port forwarding)
- Prevent system sleep or shutdown on lid-close
- Showcase full-stack integration using Linux, Web UI, mobile, and network config
| Component | Specification |

| Laptop | Lenovo G550 (Core2Duo, 3GB RAM, 320GB HDD) |
| Screen | Broken — relied on HDMI external display |
| Network | Wi-Fi LAN (router with port forwarding) |
| Clients | Android phone, Dell laptop (secondary machine) |
| Layer | Technology |
|---|---|
| OS | Linux Mint XFCE 22.1 |
| Server App | Nextcloud (Snap version) |
| Mobile Bridge | KDE Connect (Android ↔ Linux sync) |
| DNS | DuckDNS (Dynamic Public Domain) |
| Sleep Control | Caffeine + XFCE Power Config + systemd |
| Access Protocols | HTTP, WebDAV, Web UI, local mount |
- Created a bootable USB using another PC (Mintstick)
- Booted Linux Mint Live session via HDMI (since screen was broken)
- Installed OS to internal HDD
- Set up persistent external monitor using
xrandrand~/.xprofile
- Edited
/etc/systemd/logind.conf:
HandleLidSwitch=ignore
HandleLidSwitchDocked=ignore
IdleAction=ignore
xfce4-screensaver-preferences
xfce4-power-manager-settings
- Added caffeine & to auto-start session to prevent sleep
sudo apt update
sudo apt install snapd
sudo snap install nextcloud- Accessed the server from another device on the LAN: http://192.168.1.XX/
Since Snap version can't access /home, we moved files to /media/.
sudo mkdir /media/nextcloud-data
sudo cp -rv ~/Videos/. /media/nextcloud-data/
sudo cp -rv ~/Documents/. /media/nextcloud-documents/Then configured them via:
Nextcloud Admin → Settings → External Storage Set type to: Local Path: /media/nextcloud-data and /media/nextcloud-documents
