You can use TimeShift for creates system restore point.
TimeShift for Linux is a application that provides functionality
similar to the System Restore feature in Windows and the Time Machine
tool in Mac OS. TimeShift protects your system by taking incremental
snapshots of the file system at regular intervals. These snapshots can
be restored later ...
Remove packages that were automatically
installed to satisfy dependencies for some package and that are no
sudo apt-get autoremove
Clear out the local repository of retrieved package files:

Remove all files associated with removed packages (if you don’t have aptitude installed do sudo apt-get install aptitude):
This is a known bug: https://github.com/elementary/switchboard-plug-power/issues/89
There's a workaround near the (current) bottom of the page:
This problem is because the power settings are used from the gconf configuration of the user lightdm, and not the current user.
su - -s /bin/bash lightdm
gsettings get org.gnome.settings-...
This is the Captive Network Assistant (CapNet Assist). It attempts to find out if your network traffic is being caught in a captive network portal (like what you find in the airport or a coffee shop) and assist you in logging in to this captive network. elementary is still ironing out a few issues with how and when it decides to appear.
If CapNet Assist is ...
Adjust scroll speed
This is based directly on an answer to a similar question on AskUbuntu by user stvn66. I have tested it under elementary OS 0.4 Loki.
Unfortunately there is no simple setting to adjust scrolling speed right now, which seems to be a problem for many Linux based operating systems, not only elementary OS.
Currently the best option is to ...
No. This is because Ubuntu based distros that are not official spins like Linux Mint and elementary OS are based on the latest LTS versions. This is done because LTS releases are more throughly tested and are proved to be very stable. So the next elementaryOS version bump will occur when 18.04 LTS will be released.
elementary is meant to be stable. Only to those who want it stable. You have complete freedom to have your OS work like you want it to.
Just forget about doing the maintenance yourself, and touching the command line to install any software or tweak your system if you want stability. But it does provide a security risk, therefore just simply update system ...
One of the GUI-based task manager is LXTask

It can list all the processes with CPU/RAM usage, Overall CPU/RAM usage and more. It can also kill a process. You have to use up and down arrow keys to navigate.
Don't try to change display managers, desktop managers, or greeters. They're an intrinsic part of your system, you would be better off picking an OS that uses the one you want.
Drivers for Video or WiFi can obvusly break those things if selected wrong. Do plenty of research, and have a backup you can roll back to.
Do install updates.

What you should always keep in mind is the fact that if a developer does not add a visual setting to his application (or to the system settings), he has a reason for that. elementary OS tries to provide a good out-of-box experience with sane defaults. More settings visualized in your application means there is more stuff that can act unexpected or break the ...

I have faced this issue when working with static network profiles in Elementary OS Freya 0.3 and switching between local networks without a public gateway. Like Daniel had mentioned, this is a Captive Portal Assist which allows users to connect to public WiFi hotspots and immediately traps in a minimalistically launched Midori browser to complete certain ...
You can make shell scripts to achieve this. A shell script usually starts with #!/bin/bash. Let's say you want to execute sudo apt update and ls but you don't want to type it every time. So a shell script for that is,
sudo apt update
Save it with ".sh" extension and execute sudo chmod +x file_name.sh to give the file executable permission. ...
Pantheon uses a component called Cerbere as a watchdog type service that launches and monitors the additional desktop components. By default, the processes it starts and monitors are: wingpanel, plank, and slingshot-launcher. These are configurable through dconf-editor or gsettings. Take a look at the monitored-processes property in the org.pantheon.desktop....
Linux remove unuseful files automaticly way more than windows. An app like CCleaner for windows will not have much work and it is unuseful I think.
It can still detect a very few mistakes, remove the data of your programs (reset them, useful especially if you have got chrome wich stores about 2 GB on my computer even if I am nearly not using it), and see if ...
This is usually a BIOS setting. If there is nothing in there (perhaps it is set to Ctrl rather than Fn), you could try pressing Fn+Esc to toggle FnLock as is reported to work on earlier Thinkpad models.
Run sudo apt-get install --reinstall libssl1.0.0 in the terminal to reinstall the libssl library on system
I recommend before deleting a important file always rename it to YOURFILENAME.old or YOURFILENAME.bak. Then if you have problems you can always rename it back to the original name :)
So next time don't delete important files like that because you ...
It is normal for your system to have some system users and system users are usually not listed in the user accounts under system settings. To check them execute the following command in terminal,
sudo cat /etc/passwd
If you are currently logged in with the root account you can ignore the term sudo which is used to give a user superuser permission.
How can I add new user to sudoers file?
If you wish to create a user with sudo privilege, execute,
sudo adduser --ingroup sudo <username>
If you wish to add an existing user, execute
sudo usermod -aG sudo <username>
elementary OS does not officially support being used as a persistent live USB. However, the following method can be tried at your own risk:
It is possible to use third-party software to have your settings stored in the live USB. Any changes you make to the system—for example, saving a file to your desktop, changing the settings in an application, or ...
sudo swapoff -a
First we must tell the system not to attempt to mount the swap partition on boot.
sudo scratch-text-editor /etc/fstab
Comment out (place a # before) or delete the line containing your swap partition which will be similar to this.
# swap was on /dev/sda3 during installation
At the moment, elementary OS doesn't come with any parental controls. There is some work being done however here
Disallow adding and removing programs
By default, non-administrative users cannot install or remove packages.

Hold Control + Right-click the dock and select ...
The script says "You might want to run 'apt-get -f install' to correct these". Have you tried running sudo apt-get -f install? It will attempt to correct broken dependencies. Afterwards, you would want to try to install each of those programs on which GIMP depends (that's what makes them dependencies).
