Suggested January 2024 What Is Screen Tearing And How To Get Rid Of It On Linux

Unfortunately for Linux fans, screen tearing is, and has been, a persistent annoyance that doesn’t seem to be going anywhere. There are a couple of factors enabling the longevity of the screen tearing issue.

First, and probably most obviously, is the dated, broken, and bloated X server. Even with the progress of Wayland, X is here to stay for the immediate future. Next is the strange and inconsistent graphics driver picture. One of the biggest offenders in causing screen tearing is also the most popular GPU manufacturer on Linux, NVIDIA. Throw in different desktop environments with their own display settings and compositors, and you have a real mess.

These methods will hopefully eliminate screen tearing in most situations, but it’s impossible to provide a one-size-fits-all solution, thanks to the amount of variables involved. Try what applies to your system, and keep in mind that there might be new factors involved.


This isn’t the only solution for NVIDIA, and there are certainly situations that it doesn’t apply to, but it’s one of the better options, and it doesn’t rely on NVIDIA’s graphical utility that doesn’t always play nice with desktop environment configurations.

To start, you’ll need to enable setting for the NVIDIA DRM module (modsetting). Start by making a configuration file in the modprobe directory.









Open that file with your favorite text editor, and insert the following line:

Update your kernel’s initramfs to apply your change.




When that’s done, reboot. Your computer will come back up, and everything should be smoother, but you aren’t quite done yet.

Swap can save you in a pinch, but for something like graphics, its pretty terrible. The best thing you can do here to increase performance is reduce your computer’s tendency to use swap space. Start by checking your current “swappiness.”

That will probably return “60.” That’s the default value, but you can set it much lower. Open “/etc/sysctl.conf,” and add the following line at the bottom of the file:



You can set the value based on how much RAM you have. 5 to 15 is usually the range you can safely work with. Reset your computer, and everything should be smoother.


Intel graphics on Linux usually aren’t too much of a problem. That’s probably because integrated graphics usually have fewer features, and the Intel driver stack is mostly open source. For screen tearing on Intel, the solution usually comes in the form of some additional configuration.

Because Intel uses open source drivers, the Xorg configuration is going to be your most direct route. Create a file at “/etc/X11/xorg.conf.d/20-intel.conf,” then place the following block of code inside:




"Intel Graphics"







When you’re done, save and reboot.


Vsync is an attempt to synchronize your software refresh rate to your monitor hardware’s default refresh rate. In theory, it’s a great idea to make everything as smooth as possible. In reality, sometimes it lives up to its potential, and others, it makes your graphics an unstable mess. If you are using Vsync, and you’re experiencing screen tearing, try disabling it. If you aren’t using Vsync, it might be the very thing that gets things in line.


Kwin, the KDE compositor is sometimes part of the problem, too. It follows its own rules. There’s a simple bit of configuration that you can add to make Kwin smoother.

Create a new file at “/etc/profile.d/” Open that file, and place the line below in it:





Log out of KDE, and log back in for the change to take effect.


This is a pretty terrible answer, but there isn’t a setting directly in GNOME to manage vsync, but it can still really help. If you’re running GNOME with either Intel or NVIDIA graphics, follow the above instructions. If you’re on AMD, add the following line to your Xorg configuration:





XFCE is notorious for screen tearing. It’s always been a problem, and it can seriously get in the way. However, there’s a fairly simple solution. All you need to do is rip out XFCE’s compositor and replace it with a different one, in this case Compton.

Next, install Compton. It’s an independent compositor that works very well with lightweight desktops. The command here is for Debian-based distributions, but Compton is available on just about every popular distro.












Save and exit. You can either log out and log back in or run the command to start Compton.

These methods are all excellent ways to try and solve your screen tearing problems under Linux. They might not work for everyone, but with any luck, they’ll work for you. Hopefully, as more progress is made in Linux graphics drivers, desktop environments, and Wayland, the screen tearing problem will finally be resolved permanently.

3 Ways To Get Rid Of The Certificate Validation Failure On Vpns

3 Ways to Get Rid of the Certificate Validation Failure on VPNs




The most common reason for certificate validation failure on VPN is an expired certificate.

VPN certificates are essential because they are a more secure way for authentication than preshared keys.

Users reported that updating the certificate will solve the certificate validation failure error.



To fix Windows PC system issues, you will need a dedicated tool

Fortect is a tool that does not simply cleans up your PC, but has a repository with several millions of Windows System files stored in their initial version. When your PC encounters a problem, Fortect will fix it for you, by replacing bad files with fresh versions. To fix your current PC issue, here are the steps you need to take:

Download Fortect and install it on your PC.

Start the tool’s scanning process to look for corrupt files that are the source of your problem

Fortect has been downloaded by


readers this month.

VPN, an acronym for Virtual Privacy Networks has certificates by a public authority that manages them. They are essential electronic documents, as VPN devices use them to indicate if they are the ones you connect to. Thus, it is imperative to quickly fix any VPN certificate validation failure.

Digital certificates of VPN are also used for authentication, and this is more secure than preshared keys. VPN certificates expire due to security reasons and when there is a need to replace them.

It used to take a more extended period of time for a valid VPN certificate to last, however, in 2023, SSL certificate expiration was reduced and a valid certificate lasted for 12 months only.

Still, this may not be the sole reason you are getting a failure in certificate validation. There are many other reasons why this may be happening with Cisco or some other VPN service provider.

Virtual Privacy Networks improve your security and privacy as you browse the Internet, which is why people use them. Therefore if you cannot validate VPN security, the purpose of getting the VPN in the first place is defeated.

How do I get a VPN certificate?

To have access to generate a new VPN certificate, you need to create an Azure Microsoft account. Microsoft has a free trial that you can use to gain access before you need to pay.

When your VPN certificate expires, you need to update it. If you do not update your VPN certificate, you lose security and become exposed to threats that make your private and classified information vulnerable.

How do I update my VPN certificate?

Do VPN certificates expire?

VPN certificates are issued with an expiration date for the sake of increased security. After that date has passed, the certificates must be updated with fresh ones.

There is a validity period of three years attached to the VPN certificates that were issued by both the Internal RSA CA for Gateways and the Internal ECDSA CA.

How do I fix VPN validation failure? 1. Check the validity of your VPN certificate

After you check, and find that your VPN certificate may have expired, proceed to renew it.

To fix certificate validation failure VPN Cisco, and certificate validation failure VPN anyconnect, you have to first verify that the hostname and host address are still valid and then check if the certificate has expired before you proceed to install a new certificate or update the existing one.

3. Turn on OCSP Nonce on the Windows server

OCSP is Online Certificate Status Protocol, and it is a method that browsers use to ensure that a security certificate is valid. Enabling OCSP service nonce protects secure network communication.

Microsoft Windows uses RFC 5019 while Cisco AnyConnect VPN ASA uses RFC 2560. This disparity causes VPN validation failure, and as such needs fixing.

When OpenVPN certificate verification failed and VPN certificate validation failure occurs, these are the steps that you can follow to rectify them.

Also, for IBM VPN certificate validation failure, there is a renew certificate application in the IBM store that can help you with renewing your certificate if it is outdated.

How do I add a VPN certificate to Windows 10/11? Is there any good 3rd party VPN for business?

There is another security method to protect all your business data and avoid certificate validation failure for your VPN protection.

You can use the Perimeter 81 as a Zero Trust Application Access software and secure any sensitive data from public use. This way, you guarantee private communication with IPSec or WireGuard technology.

Plus, it provides safer digital support against data leaking or cyber threats with access by role, a cloud-based interface, or monitoring tools.

What Is Offload App And How To Use It On Iphone, Ipad

Seeing the Storage Almost Full alert on your iPhone? In these situations, Offload App is a handy solution to manage space. You can use it automatically or manually to free up local iPhone storage. This tutorial will teach you what app offloading is, how to enable it, and how to re-download offloaded apps.

What is Offload App on iPhone and iPad?

In the earlier days of iOS, you had two options for an app: you either kept it on your iPhone or you deleted it. If you kept it, the app and its data continued to occupy local storage. If you deleted the app, the app itself and all its local data was gone.

In iOS 11, Apple introduced the option to offload apps. This is somewhat of a middle ground between keeping and deleting an app.

When you offload an app, the app itself is deleted, which clears local storage. But the app documents and data are still saved locally on your iPhone. Once you reinstall the offloaded app, you can keep using it like before as the app data is still saved. In other words: As opposed to deleting an app, which nukes its binary and data out of orbit, offloading ensures that app data, along with user settings and documents, remain on your device.

Given the increasing app sizes, it is sensible to offload apps to keep local iPhone storage unoccupied. And thanks to the availability of Wi-Fi pr cellular, downloading an app is quick and easy.

So, whether you have a 16 GB, 32 GB, 64 GB iPhone, or one that’s full, offloading apps is a great way to optimize storage. You can do it manually or have your iPhone offload apps automatically.

How to manually offload apps on iPhone and iPad

Open Settings and tap General.

Tap iPhone Storage and give it a while to load.

From the list of apps, tap the app you want to offload.

Tap Offload App and confirm.

Can I offload all apps?

You can offload all third-party apps you downloaded from the App Store and several Apple apps like TV, Music, Mail, Files, Maps, Books, Reminders, Podcasts, Contacts, Calendar, Shortcuts, Measure, Home, Compass, Stocks, FaceTime, Tips, iTunes Store, Translate, Calculator, Weather, Voice Memos, Notes, Magnifier, and all other Apple apps like iMovie, Numbers, Pages, Keynote, Apple Support, Apple Store.

You cannot offload or delete Photos, Phone, Safari, Wallet, Messages, and Health apps.

One interesting thing to note is that if you have an Apple Watch paired with your iPhone, you cannot delete or offload the Watch and Fitness apps. But if you don’t have an Apple Watch paired, you can offload or delete the iOS Watch app.

If you offload or delete the FaceTime app, you can continue to make FaceTime calls from the Phone or Contacts app.

How to automatically offload apps on iPhone and iPad

Manually finding and offloading apps can be a chore. If you struggle to keep local space free, you can let your iPhone offload apps automatically to optimize storage. Once you enable it, your iPhone will automatically offload apps that you have not used in a while.

Here’s how to set automatic offloading of apps on iPhone and iPad:

Open Settings and tap General.

Tap iPhone Storage.

Under Recommendations, tap Enable next to Offload Unused Apps.

Caution: Some people enable this, forget about it, and then worry as they have to re-download the app again.

How to re-download an offloaded app

Even after you offload an app, its app icon stays on the Home Screen and App Library. You’ll see a download arrow before the app name, which signifies that this app is offloaded. Tap the app icon to download it again. As mentioned, the app data is still on the device.

Finally, you can also search for the app in the App Store and tap the download button.

What Is ‘New To You’ On Youtube And How Does It Work?

Since the very beginning, YouTube has been quite capable of recommending relevant videos. Now, with machine learning operating at its peak, the recommendation system has gotten even sharper, allowing you to explore different videos across the board. 

To make exploration more fun, YouTube has introduced another neat, new feature, which would allow you to refresh your feed whenever you need it. So, without further ado, let’s check out what ‘New To You’ is and how it would help you find new recommendations.

What is ‘New to You’ on YouTube? 

For mobile devices, ‘New to You’ is a new tab on the YouTube app that would allow you to get fresh recommendations, beyond the standard recommendations you get on the home screen. It only includes videos that you haven’t watched, allowing you to explore different categories. 

The feature has been enabled through a server-side update on mobile devices. The feature can be availed through the computer — desktop browser — as well but it’s not as straightforward as the mobile client.

How does ‘New to You’ work?

Usually, the standard YouTube feed is quite capable of throwing a list of recommended videos at you. However, if you have been consuming YouTube regularly, your news feed might get a little boring, with older/already watched videos populating the primary feed more often than not. 

‘New to You’ is a breath of fresh air in that respect — especially on your mobile device. The new recommendation system offers you videos that you haven’t seen yet, while also keeping your preferences in mind. It keeps track of your watch and search history, but widens the scope of recommendation, resulting in curated recommendations that are not identical to the stuff you already watch.

So, all in all, you get a nice recommendation system that not only keeps you interested but also doesn’t recommend stuff that is too wild for your liking.

Is ‘New to You’ personalized?

‘New to You’ is not as personalized as your regular explore feed, but there are elements that you will find familiar. For example, ‘New to You’ shows you videos that are in line with the stuff you generally watch. So, in that sense, it is personalized to an extent.

However, it doesn’t show you videos from channels you are already subscribed to. You get fresh videos from channels that might interest you, which can help your watchlist grow organically. It’s not as personalized as your Explore feed but feels a lot more targeted than the Discovery space.

Relevancy is a key term when it comes to ‘New to You,’ more so than personalization.

How to find ‘New to You’ on Mobile

If you are running the latest version of the YouTube app, you may have received the server-side update by now. To use the ‘New to You’ recommendation system, all you have to do is launch the YouTube app and go to your ‘Home’ tab.

At the top, on the right of the ‘Explore’ section, you should find the ‘New to You’ tab.

If you don’t swipe down to refresh the feed. Once you get the button, tap on it to explore the ‘New to You’ feed.

How to find ‘New to You’ on computer

If you have subscribed to thousands of channels over the course of your YouTube history, you might not even see the button appear on YouTube. 

Why is your ‘New to You’ button not glowing?

When you have a new recommendation the ‘New to You’ tab would have a blue-magenta border around it. When you exhaust the list of recommendations, the tab stops glowing and resembles any other tab on the page. So, if your ‘New to You’ button seems ordinary and sits at the end of the top carousel, YouTube is just asking for a bit of time to catch up with you. 


What Is Kovter Malware And How To Stop It?

What Is Kovter Malware And How To Stop It? What is Kovter? How Did Kovter Evolve?

This trojan virus can’t spread by itself and needs the support of the user to run this by mistake on their laptops/PC or visit a site that is hacked or infected. Now you must be wondering about how and when this virus came into being, and here is the answer:

1. It was in 2013 that it was heard for the first time and at that moment it was pegged as a police ransomware, where it remained hidden in target computers and attacked only when someone illegally downloaded files. It triggered a warning message for the user then, and a fine which was equal to a ransom demand.

3. In 2023, it became a file less malware, which was hard to find, and it infected various devices through an installation of autorun registry entries.

4. 2023 saw another evolution in it, and this was the addition of more files and registry entries.

5. The current form (2023) of this malware uses attachments coming from malicious spam for infecting the computers:

These malicious attachments are usually corrupted Microsoft file, once users download these files; it creates a shortcut, batch file and a random file with any extension.

Also, some registry entries are created. When the users restart the infected computer or open any of the shortcut/registry files, the malware starts attacking the computer.

Once installed, Kovter continuously monitors every function done via the infected computer.

Symptoms That Indicates A Malware Presence:

A file less malware is hard to find, but still, there are some hints like:

The task manager may show that processes like chúng tôi or chúng tôi are running on the PC.

An alert that states that PowerShell has stopped working

Slow upload or start for any app

Blocked or unreachable web pages

How To Stop Kovter From Infecting Your Pcs?

1. Security Updates: As soon as the updates are available, apply them as they keep this malware at bay. Also, update windows as old/outdated windows tend to attract much malware.

3. Anti-spam filters: Since the latest variant of Kovter comes through spam emails, organizations must have policies to avoid email-threats. Anti-spam filter is a great way to stop malicious emails to reach the mailboxes of users.

4. Have firewalls: Firewalls and solution can keep a lookout for this malware even though it is hard to detect.

5. Security Program: Always have a good and original version of an antivirus/anti-malware installed in your PC. Go for an antivirus that provides Malware removal tool.

It helps to be aware of such a malicious trojan that may harm your PC and steal your personal data. Also, the best thing is to keep backing up your important files/data so that even in case of getting infected, your data is safe. Practice these tips for a Kovter-free computer.
