DeskLCD

A small Linux desktop app to manage an LCDproc display: start and stop the LCDd service and the lcdproc client, and choose which information screens (CPU, memory, disks, clock, ...) appear on the LCD, without editing /etc/lcdproc.conf by hand.

• English and Italian interface (follows the system language).
• Lives in the system tray: closing the window keeps it running, Exit is in the tray menu.
• Can start itself at login, with a checkbox.

Install

You need lcdproc (LCDd and the lcdproc client: sudo apt install lcdproc on Debian/Ubuntu) and a desktop session (X11 or Wayland) with a polkit agent, which KDE and GNOME already run.

Download from Releases:

• desklcd_<version>_amd64.deb (recommended): includes its own Java runtime, installs under /opt/desklcd and adds a menu entry.

  sudo apt install ./desklcd_<version>_amd64.deb

• desklcd-<version>.jar: a single jar for any Linux x86_64 system with Java 11 or later: java -jar desklcd-<version>.jar. To add a menu entry by hand:

  mkdir -p ~/.local/share/applications
  cat > ~/.local/share/applications/desklcd.desktop <<EOF
  [Desktop Entry]
  Type=Application
  Name=DeskLCD
  Comment=GUI for LCDd/LCDproc
  Exec=java -jar /path/to/desklcd-<version>.jar
  Terminal=false
  Categories=System;
  EOF

Usage

The window has three tabs.

Status

• LCDd service: whether the systemd service is running and enabled at boot, since when, with Start, Stop and Restart.
• lcdproc client: the program that actually draws the screens on the LCD. Shows whether it is running (started from DeskLCD or from outside), with a start/stop button.
• Startup: launch DeskLCD automatically at login.
• Active modules: turn the lcdproc Client and Custom Client tabs on or off.

lcdproc Client

• One checkbox per screen (CPU, SMP CPU, CPU graph, load, memory, process size, disk, network interfaces, battery, time and date, clocks, uptime, about); hover a checkbox for a description.
• Reload reads /etc/lcdproc.conf again, Save writes it. The client reads its configuration only at startup, so after saving DeskLCD offers to restart it.
• Connection...: LCDd server and port, and the client's runtime settings (report level, syslog, foreground, PID file, display name).

Custom Client: reserved for a client of your own; empty for now.

Controlling the service and saving /etc/lcdproc.conf need root: DeskLCD asks through pkexec, so the usual graphical password prompt appears.
