Ubuntu, like another working system, it has a corresponding lock screen. And this seems in two moments: when beginning up and when we aren’t utilizing the PC for some time. From it we will choose the consumer we wish to use, enter the password and that is it.
However, if we don’t want to use this lock screen to enhance the workflow of our Linux, subsequent we are going to see how we will deactivate it in two other ways.
Disable consumer lock screen when turning on PC
When we activate Linux, after loading systemd, we are going to see the residence screen. All the customers that we’ve got created will seem in it, and we will select with which ones we wish to begin utilizing Ubuntu.
This screen will at all times seem, no matter the variety of customers we’ve got created, so long as we do not need computerized login activated. To do that, what we should do is open the Configuration menu of our distro, and go to the part of “Users”. The very first thing we are going to do is unlock the choices by clicking on the button that seems at the high of the window to find a way to modify them.
Once this selection is deactivated, we will modify these settings. We are keen on the computerized login, due to this fact, we are going to examine this field and save the modifications.
From now on, once we activate the PC, the session will routinely begin for our consumer with out seeing this lock screen after boot.
Prevent Ubuntu from crashing after idle time
One of the important safety measures for any laptop system is to lock it when we aren’t sitting in entrance of it. So we will make sure that no one touches our PC with out permission nor gossip between our information. Normally, working methods are normally configured in order that, after a sure interval of inactivity (a couple of minutes, hours, and so forth.) it’s routinely blocked. the session remains to be open, however so as to use the PC we are going to want to enter the password once more on it.
Ubuntu, as anticipated, permits us to modify these parameters. The screen lock configuration choices could be present in the part of “Privacy”, inside the Settings menu.
From right here we can be ready to configure all the things associated to the laptop lock. For instance, we will select how lengthy we wish it to cross till Ubuntu turns off the screen (with out blocking), if we don’t want the computerized blocking to be activated, mix the two choices (flip off the screen after which block) and likewise if we wish the session to be lock routinely when the laptop is suspended or if we wish to see private notifications on this lock screen.
We can configure these parameters to our liking. If we dwell alone, we will depart the lock screen deactivated, but when we dwell with different folks and we’re involved about our privateness, then it’s vital to have it activated, since it’ll assist us to forestall different folks from benefiting from when we aren’t round to entry our laptop.
Two customers? You should use the lock screen
The above is efficient, and protected, once we solely have one consumer on the PC: ours. However, if we have already got one other consumer created, it signifies that we’re sharing a PC with one other particular person. Therefore, the lock screen is essential in order that the information of every consumer is protected, and likewise to find a way to select which consumer to open when the PC is turned on.
Can we disable it? Of course, nothing prevents us. But we should keep in mind that, each time we activate the PC, the consumer who has configured it will likely be routinely logged in, so if the different particular person has entry to the PC, they are going to be ready to entry all our information. And, to attain your username, you’ve gotten to manually log off to open the new one.
If we fear about lock the PC each time we stand up of the chair (from the GNOME menu, with a keyboard shortcut, and so forth), then what we will disable is the computerized system lock.
Other safety measures to defend Linux
The lock screen is a really primary layer of safety. It may also help us forestall different folks from accessing our session and information from the system itself. However, they will at all times load one other working system, and even take away the onerous drive from the PC, to join it to one other laptop and entry all their data as if it had been simply one other exterior onerous drive.
To forestall this from occurring, what we should do is resort to different configurations similar to the disk encryption. Either with the Linux utility itself, or with third-party instruments similar to TrueCrypt, If we encrypt the information on the disk, no one or nothing can be ready to learn it. When we activate the PC, a screen will seem straight, earlier than loading the working system, which is able to ask for the password.
Once we enter the password, the information can be decrypted and the system will start loading. If we don’t enter the password, no one can be ready to get well the information, not even when they mount the onerous drive on one other laptop with one other working system. Of course, to be protected we should make sure that to enter a password as safe as attainable, or we may have issues.
