Backup your system (Create Restore points)
After installing the tool, search for and open it either from system start menu or ‘Activities’ overview depends on your desktop environments.
On the first launch, the setup wizard will ask you to choose snapshot type, destination location, setup daily backup, whether to backup user files (excluded by default). And, it’s OK to use Default options, since there’s ‘Settings’ page to re-configure them later.
After setup wizard, click on “Create” button on the main UI to start creating the first restore point!
The first backup can take quite a few minutes and dozens of GB disk space (Make sure you have enable free space for saving the first snapshot)! The 2nd, 3rd, … backups can be faster and smaller, because it shares common files between snapshots to save disk space.
After created backups, they are listed in the main UI window. Simply highlight one, then you can browse its content, copy and save it into another storage device if want.
And, just click ‘Restore‘ will revert your system to the status it was when you created that snapshot, without touching user documents, music, videos, etc, unless you included them in setup Wizard.
Uninstall Timeshift
Before removing the software, you may choose to remove all the backup snapshots that you don’t need anymore to free up disk space.
Then, open terminal and run command to remove the app package:

Want to change system power mode between Performance, Balanced, and Power Saver automatically when plug / un-plug power supply?
Here’s an extension can do the job for Ubuntu 22.04, Ubuntu 24.04, Fedora 38/39, Debian 12, Arch and other Linux with GNOME from version 42 to 46.
GNOME introduced setting options to switch power mode since v40. For laptop running on AC power supply, user may use ‘Performance’ mode for gaming or doing heavy work. To prevent from draining power fast after un-plug AC power, it’s better to switch to ‘Balanced’ mode, or even ‘Power Saver’ mode when battery level is low. To automate this work, ‘Power Profile Switcher’ extension was born. Continue Reading…
Unlike Windows, Ubuntu so far does not have real-time GPU usage info displayed in its system monitor application. If you want to check how much your graphic card is in use, then this simple tutorial may help!
Method 1: Use Mission Center (Graphical App)
A graphical app is always good choice for beginners. And, Mission Center is the one that provides a Windows Task Manager look like interface for monitoring system resource usage.
It supports monitoring overall GPU usage, video encoder and decoder usage, memory usage and power consumption. With the power of nvtop, it supports AMD, Apple, Huawei, Intel, NVIDIA and Qualcomm GPUs.
To install Mission Center, press Ctrl+Alt+T on keyboard to open up a terminal window. Then, run the commands below one by one to install the Flatpak package.
First, run command to enable Flatpak support:
sudo apt install flatpak
Then, install Mission Center flatpak package via command:
If this is the first app installed as Flatpak package, you may need to log out and back in to make app icon visible in start menu (or Gnome app grid).
(Optional) To uninstall Mission Center, open terminal and run command:
Also run flatpak uninstall --unused to clear useless runtime libraries.
Method 2: Monitor GPU usage from Command Line
For Ubuntu server and those who prefer to the job from command line, there are few tools can do the job. They include intel-gpu-tools for Intel GPU, and nvtop for Intel, AMD, and NVIDIA.
Check Intel GPU usage in Ubuntu:
For the integrated Intel graphics card, there’s a command line tool intel_gpu_top can do the job.
1. First, press Ctrl+Alt+T on terminal to open a terminal window. When it opens, run command to install the package:
sudo apt install intel-gpu-tools
Type user password when it asks (no asterisk feedback) and hit Enter.
2. Then, run command to start it:
sudo intel_gpu_top
As you can see, it shows real-time IMC read and write speed, power usage, as well as percentage usage of 3D/Render, Blitter, Video, and VideoEnhance.
Monitor AMD/NVIDIA GPU usage in Ubuntu
For NVIDIA and AMD graphics card, there’s a htop like task monitor called nvtop (Neat Videocard TOP).
It shows real-time GPU and GPU Memory usage in both total and per process basis, along with temperature, power usage, and graph information.
nvtop, image from https://github.com/Syllo/nvtop
nvtop also supports Intel GPU, however, it does not work in my case with i5-4590 (HD4600), and i3-6006U (HD 520).
Install nvtop in Ubuntu:
The tool is available in Ubuntu system repository, but old for Ubuntu 22.04 and Ubuntu 20.04. For the latest version, it has an official PPA contains the most recent package.
1. First, press Ctrl+Alt+T on keyboard to open terminal. Then, run command to add the PPA:
sudo add-apt-repository ppa:flexiondotorg/nvtop
For Ubuntu 24.04, skip the PPA, just the command below to install. Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2. Then, run command to install the tool:
sudo apt install nvtop
For Linux Mint, run sudo apt update first to refresh package cache.
Finally, either search for and launch it from ‘Activities’ overview (or start menu), or run nvtop command to start monitoring your GPU.
(Optional) Remove nvtop
To remove the PPA repository, open terminal and run command:
This simple tutorial shows how to fix the launching issue for TypeCatcher in Ubuntu 22.04 or other Linux with Python 3.9 & higher.
TypeCatcher is a simple GTK application to download and install Google webfonts for off-line use. The app is available to install in Ubuntu Software for all current Ubuntu releases. However, it does not launch in Ubuntu since 21.10.
TypeCatcher, download & install Google Fonts
When trying to launch it from command line, it outputs something like this:
Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/typecatcher_lib/Application.py”, line 30, in on_activate
self.window = TypeCatcherWindow.TypeCatcherWindow()
File “/usr/lib/python3/dist-packages/typecatcher_lib/Window.py”, line 47, in __new__
builder = get_builder(‘TypeCatcherWindow’)
File “/usr/lib/python3/dist-packages/typecatcher_lib/helpers.py”, line 44, in get_builder
builder.add_from_file(ui_filename)
File “/usr/lib/python3/dist-packages/typecatcher_lib/Builder.py”, line 86, in add_from_file
ele_widgets = tree.getiterator(“object”)
AttributeError: ‘ElementTree’ object has no attribute ‘getiterator’
The issue is because of the removal of getiterator() methods from xml.etree.ElementTree module in Python 3.9, which was deprecated since Python 3.2.
As the announcement indicates, simply use iter() method instead will fix the issue.
Methods getchildren() and getiterator() of classes ElementTree and Element in the ElementTree module have been removed. They were deprecated in Python 3.2. Use iter(x) or list(x) instead of x.getchildren() and x.iter() or list(x.iter()) instead of x.getiterator().
1. First, search for and open a terminal window from either start menu or ‘Activities’ overview depends on your desktop environment.
2. When terminal opens, run command to edit the file that contains the ‘getiterator()’ method (see the first screenshot). In the case, it’s “/usr/lib/python3/dist-packages/typecatcher_lib/Builder.py”.
replace gedit to your favorite text editor, or use nano command line editor that works in most Linux.
3. When files opens, find out and replace tree.getiterator with tree.iter.
For Gedit text editor, just go to menu, click open ‘Find and Replace’ dialog. Finally, insert tree.getiterator as ‘Find’, and ‘tree.iter‘ as ‘Replace with’, then click on ‘Replace All’ button.
For nano text editor, press Alt+R when the file opens in terminal window. Then type tree.getiterator when it indicates ‘Search (to replace)’, hit Enter, and insert tree.iter when prompts ‘Replace with’. Finally, hit Enter and type y. Or, just use arrow keys to find and replace the keyword (there are 2) manually. And, press Ctrl+x, type y, and hit Enter to save changes.
After saving the file, try to launch it either from ‘Activities’ overview or command line, and enjoy!
