This simple tutorial shows how to install the latest Eclipse IDE in Ubuntu while the one in Ubuntu Software is always old.

Eclipse in Ubuntu Software is the containerized snap package and it’s old. Fortunately, an official installer is available for Linux.

1. Download & start Eclipse Installer:

Firstly go to the official download page, and grab the installer:

Then extract the tarball, and go into the result folder. Right-click and select “Run” the eclipse-inst file.

Or you can right-click on blank area and select “Open in Terminal”, and then run ./eclipse-inst in the pop-up terminal:

2. Install Eclipse:

When the installer wizard opens, choose “Eclipse for Java”, “Eclipse for Javascipt and Web”, or other that you want to install.

Next click on “Install” button, and accept the license to start installing the IDE:

The software is by default installed to the user home folder for single user use. Once installed, you can launch it either from system application launcher or the desktop shortcut (need to first right-click and choose “Allow Launching”).

How to Remove Eclipse Completely:

The software is installed by default in user’s home directory. Simply open the file manager, and remove the eclipse folder and eclipse-workspace folder.

For the desktop shortcut, just move it to trash. For app shortcut in the system launcher, press Ctrl+Alt+T to open terminal and run commands:

  • navigate to app shortcut folder for local user:
    cd .local/share/applications/
  • remove all Eclipse related files:
    rm *eclipse*.desktop epp*.desktop

Change Folder Color

Want to make a certain folder different to others in Ubuntu? You can change the icon color and add emblem via Nautilus extension.

Nautilus, the default file manager in Ubuntu, has an extension called Folder Color. It allows to change the color of selected folder or folders into: Blue, Blown, Green, Gray, Pink, Purple, Red and Yellow.

You can also add a emblem, e.g., Important, In Process, Favorite, Finished, and New. And reset to default is also available in folders’ context menu.

Install Folder Color:

The extension is available in Ubuntu universe repository. However, it’s not well working with the default Yaru theme.

So you have to first add the developer’s PPA with Yaru integration. To do so, open terminal (Ctrl+Alt+T) and run command:

sudo add-apt-repository ppa:costales/yaru-colors-folder-color

Type user password (no asterisk feedback) when it asks and hit Enter to continue.

Then install Folder Color, as well as Yaru integration via command:

sudo apt install folde-color yaru-colors-folder-color

To apply change, run command to restart Nautilus file manager:

nautilus -q

Finally, open file manager, right-click on a folder and enjoy the new icon colors:

How to Install qBittorrent 4.3.5 via PPA:

The official qBittorrent PPA has built the new release packages for Ubuntu 20.04, Ubuntu 20.10, and Ubuntu 21.04.

1. To add the PPA, open terminal by either pressing Ctrl+Alt+T on keyboard or searching for “Terminal” from application menu. When it opens, run command:

sudo add-apt-repository ppa:qbittorrent-team/qbittorrent-stable

Type user password (no asterisk feedback) when it prompts and hit Enter to continue.

2. If an old version was installed on your system, upgrade it via Software Updater,

upgrade qBittorrent

or run following commands to install /upgrade qBittorrent in terminal:

sudo apt update

sudo apt install qbittorrent

To remove qBittorrent PPA, either go to Software & Updates -> Other Software, or run command in terminal:

sudo add-apt-repository --remove ppa:qbittorrent-team/qbittorrent-stable

To remove the bittorrent client, either use your system package manager or run command:

sudo apt-get remove --autoremove qbittorrent

Since Ubuntu 21.04 uses Wayland as default display server, the previous method using xrandr does not longer work for adding custom screen resolution.

So this tutorial is going to show you another way to add your favorite screen resolution if it’s not available in Display settings.

In the case, I’ve the default 1920X1080 (16:9) resolution. However, I prefer 1600X900 (16:9) a little more which is not available in settings.

Before getting started:

In this tutorial I’m going to add video mode option as Kernel parameter. The good side is that it works on both Wayland and Xorg.

Downsides includes:

  • You can’t set custom resolution higher than the maximum one in Display settings. In my case (see the picture above), X resolution must be less than 1920, and Y resolution have to less than 1080.
  • If you have dual-boot or multi-boot systems, below steps may not work for “other Linux” in Grub boot menu. For instance, I’ve Ubuntu 21.04 and Ubuntu 20.04 dual-boot in my laptop, the startup boot menu is handled by Grub for Ubuntu 21.04. It lists Ubuntu 21.04 as the first menu entry, custom Kernel parameter does not work for Ubuntu 20.04 in my case.

And after adding the parameter, the custom resolution should appear in Display settings, 1600×900 for instance:

How to Tell the Display Device Name in Ubuntu:

Firstly, you have to find out the current Display name. To do so, open terminal from the system application launcher:

When terminal opens, run command:

for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done

As the picture shows, it’s eDP-1 in my case.

How to add video mode kernel parameter:

Option 1.) edit Grub configuration file.

a.) Open terminal from system app launcher. When it opens, run command to edit the config file:

sudo gedit /etc/default/grub

You may replace gedit with other text editor for Ubuntu based systems.

When it opens, add video=eDP-1:1600×[email protected], in my case, as value for “GRUB_CMDLINE_LINUX_DEFAULT”.

IMPORTANT: you have replace video=eDP-1:1600×[email protected]:

  • eDP-1 is the Display Device Name, you can find it in previous step.
  • 1600×900 is the desired screen resolution. Replace it with yours.
  • 60 is the refresh rate. It’s OK to skip it, so it will be video=eDP-1:1600×900

There are more flags for the video mode kernel parameter. See the documentation for detail.

b.) Finally apply changes by running command:

sudo update-grub

And reboot.

Option 2.) use Grub Customizer:

Grub-Customizer, the popular graphical tool offers an option to add the Kernel parameter.

Install it from Ubuntu Software if you don’t have it. Then launch it and navigate to General Settings tab. Finally add the value and click on Save button.

Set Custom Resolution for Multiple Displays:

If you have multiple monitors connected to your Ubuntu machine. It’s OK to set one screen resolution for all displays, or use more “video=” parameter for each display.

a.) To set one screen resolution for all displays, just skip the device name. For instance:

[email protected]

It will add 1600×900 screen resolution with 60 Hz refresh rate for all the connected displays.

b.) To add more “video=” parameter. For instance, I have two displays: eDP-1 and DP-1 connected. And to add 1360×700 for eDP-1 and 1600×900 for DP-1, use:

video=eDP-1:[email protected] video=DP-1:[email protected]

That’s all. Enjoy!

Nvidia Linux driver

NVIDIA graphics driver for Linux released version 465.27 a day ago with new Laptop GPUs support and a few bug-fixes.

In NVIDIA 465.27, following new GPUs are supported:

  • T600 Laptop GPU
  • T1200 Laptop GPU
  • RTX A5000 Laptop GPU
  • RTX A4000 Laptop GPU
  • RTX A3000 Laptop GPU
  • RTX A2000 Laptop GPU

There are also some fixes in the release including:

  • Fixed a bug that could prevent a system from resuming from suspend when DisplayPort activity occurred while the system was suspended.
  • Fixed a regression that prevented eglQueryDevicesEXT from correctly enumerating GPUs on systems with multiple GPUs where access to the GPU device files was restricted for some GPUs.
  • Fixed a regression that could cause system hangs when changing display resolution on SLI Mosaic configurations.
  • Fixed a bug that could result in blank displays when driving multiple displays at the same resolution using active DisplayPort dongles.

How to Install NVIDIA 465.27 in Ubuntu:

Ubuntu now builds the latest NVIDIA drivers and pushes them via its own security & updates repositories.

Just wait! It’ll be available in next few days. At that time, launch Additional Drivers utility and you’ll see the driver available to install.

If you can’t wait, go to NVIDIA website and download the .run installer package (not recommended for beginners):
