      *) Should run with Java 8 - Java 15

     
Please note that the author of jLog will only test Linux versions of jLog on Linux Mint 20 LTS x64 and Ubuntu Linux 18.04 LTS & 20.04 LTS Desktops.
      jLog is expected to run with most other variants and versions.


Instructions

  1. Unless already installed, please install the Java Runtime Environment. JRE V1.8 or newer is recommended.

    Note for Ubuntu users: Adding this line:
              JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=on  -Dswing.aatext=true'
    to /etc/environment
    may fix font scaling problems with Java Swing applications like jLog.

    if not, try one of these three alternatives:

    • Change desktop fonts, by experimenting with font family and scaling factor, e.g.:
      gsettings set org.gnome.desktop.interface font-name 'Ubuntu 10'
      gsettings set org.gnome.desktop.interface text-scaling-factor 0.93
    • Open jLog's Profile->Fonts and for the Dialog font: Set Ubuntu Condensed size=14
    • Open jLog's Profile->Fonts and set Font size change to -1 (or -2)

  2. if you want to uninstall e.g. JDK11 and replace it with JDK8 which has a good implementation of Java Swing:
       sudo apt remove openjdk-11-jre-headless openjdk-11-jre openjdk-11-jdk-headless openjdk-11-jdk
       sudo apt install openjdk-8-jdk

    It may be necessary to run: sudo chmod a+rw /dev/ttyUSB* (or similar name to access the USB radio interface devices) after restarting Linux.

  3. Log in as the preferred user and download installer.jar.
    Then, make sure that the installer file is executable by right-clicking and selecting Properties. Under Permissions, check the 'Allow executing the file as program' and close the Properties dialogue.

    Start the installer by right-clicking the installer file, then clicking "Open With Java" (or similar).
    This should start the jLog Installer. Use the default values unless you are very confident with Linux.

    You should find the installed jLog, either in a "jLog6" folder at the top-level of the Start Menu, or in the "Other" folder.
    Once found, you may right-click jLog and pin it to the Start Menu or the Taskbar.

  4. To increase log capacity beyond 25000 - 30000 entries per file, you must change the Java VM properties.

  5. Note that the default UTF-8 environment in SuSE V 9+ may need to be changed to e.g. ISO-8859-1. See changing charset.
