The qBittorrent 4.3.3 was released a few days ago. Here’s how to install it in Ubuntu 20.04, Ubuntu 20.10, Ubuntu 18.04, and Linux Mint 19.x / 20.

This release contains mainly bug-fixes. Because Xcode doesn’t support C++17, Mac OS 10.13 (High Sierra) is no longer supported. And Ubuntu 18.04 is highly to be dropped in the next release.

qBittorrent 4.3.3 release highlights:

  • New languages Azerbaijani, Estonian support.
  • Unify global speed dialogs for normal/alternative speeds.
  • Increase maximum global speed limits ~2 GiB/s.
  • Save fastresume when setting torrent speed limits.
  • Group several torrent options into one dialog.
  • Capitalize locale names.
  • Improve content file/folder names handling.
  • Drop notification about move storage finished or failed.
  • Reload “missing files” torrent instead of re-checking.
  • Remember dialog sizes.
  • Improve detection of file extension string.
  • WEBUI: Don’t call non-existent elements.
  • Update “Keep top-level folder” in WebUI options.
  • LINUX: Use legacy ‘data’ directory only as a fallback.
  • Bump project requirement to C++17.

Running Ubuntu with high refresh rate monitor? You may found that the Firefox web browser does not match with your monitor’s native refresh rate.

This is a simple tip shows how to change the refresh rate of Firefox, though you have to first set the system refresh rate (Settings -> Displays) to match your monitor.

1.) Open Firefox and type about:config in address bar and hit Enter. And click the button which says ‘Accept the Risk and Continue’.

2.) Next in the filter box, type layout.frame_rate and click edit the key value to your monitor’s native refresh rate (144 in the case).

That’s it. Restart Firefox and enjoy!


GIMP extra color palettes

For Ubuntu 18.04 users sticking to the PPA build of GIMP image editor 2.10.22, now the Python Script support is back.

Since old GTK2 and Python 2 libraries being removed from Ubuntu universe repositories, the Python script support was excluded due to lack of dependencies when I was uploading the GIMP packages into PPA.

Ubuntu 18.04 was neglected, though. It meets all the dependencies to build the requested feature. So I added it back. Hope it’s not too late for you :). And the package was totally built via the rules from otto-kesselgulasch’s PPA.

Install GIMP 2.10.22 via PPA in Ubuntu 18.04:

NOTE I do only basic image editing with GIMP, and I can’t go further test for the function though it seems working.

1.) Open terminal from system application launcher. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/gimp

Type user password (no asterisk feedback) for sudo prompts and hit Enter to continue.

2.) If an old version of GIMP .deb package was installed, upgrade it via Software Updater (need to install gimp-python manually) utility.

or run apt commands in terminal to install GIMP:

sudo apt update

sudo apt install gimp gimp-gmic gimp-python

If an old version was installed, it’s recommended to run sudo apt upgrade which will also update the required babl, gegl libraries.

How to Restore:

To restore GIMP to the stock version in main Ubuntu repository, run command to purge the PPA:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/gimp
