I've been using Ubuntu 26.04 daily build on my Dell 3585 and there is a bug causes my machine fail to boot. The system stuck at boot session with this following error message: boot micmute setting an led's brightness failed (-5) I've updated the system and sadly, the bug hasn't been solved. Luckily, I've found a quite simple solution from internet. sudo nano /etc/default/grub Add  "module_blacklist=dell_laptop" parameter to  the default grub parameter: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash module_blacklist=dell_laptop" Save the file, update grub: sudo update-grub Last, reboot your system.

I am currently using OpenMandriva Lx ROME and I love it. It boots and loads really fast on my AMD Ryzen laptop. Unfortunately, KDE's brightness control is not working and I have to use xrandr to control the brightness manually. The Simple Solution After reading random forums about this not-really-uncommon issue, I've successfully solved the issue by these following simple steps: Using your favourite text editor, edit /etc/default/grub In GRUB_CMDLINE_LINUX_DEFAULT remove acpi_backlight=vendor then, add amdgpu.backlight=0 Update grub: sudo grub2-mkconfig -o /boot/grub2/grub.cfg Reboot the system. Now, the KDE's brightness control should work properly.

Without doubt, Mozilla Firefox is the most popular web browser in Linux. It is the default web browser installed in almost all major Linux distributions currently exist. There are many ways to install Firefox on your Linux distribution. The easiest way is by using your default Linux distribution's repository. Unfortunately, Ubuntu has decided to switch to Snap to install Firefox in its official repository, and many users aren't happy with that decision. Many users then choose to find a third party repository, and or download the official Firefox binary from the official Mozilla Firefox website. However, you might find an error message when trying to run Firefox binary. You might find this following error message XPCOMGlueLoas error for file libxul.so . The Simple Solution Libxul.so exists in Mozilla Firefox folder, but it fails to load because there is a missing dependency in your Linux system: libdbus-glib-1-2. So, to solve the issue is by simply installing the package: sudo a...

SSD are now becoming cheaper. With better speed, people prefer to use SSD as their main storage device.  Unfortunately, there is an error message if you are using NVMe storage when your Linux system is booting: failed to set apst feature . The message doesn't indicate your NVMe is broken. It is just a message that there is a spesific NVMe feature that currently can't be loaded properly in Linux kernel.  If you are annoyed by the message, you could easily disable it by doing these simple steps: 1. Using your favorite text editor, edit this file: sudo vi /etc/default/grub Find the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" And put this line: nvme_core.default_ps_max_latency_us=0 To be like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=0"  2. Save the file and update grub: sudo update-grub 3. Now, you won't see the message again when your Linux is booting.

If you're used to use Ubuntu, you would easily mount your harddisk partitions in file manager by clicking it. But in Debian, you have to enter your password, everytime you mount your partitions in file manager. Not a really big deal, but it would be simpler if you don't have to. Here are very simple steps to make your Debian able mount your harddisk partitions without password: 1. Using your favorite text editor, edit this file: sudo vi /usr/share/polkit-1/actions/org.freedesktop.UDisks2.policy Find a line  <allow_active>auth_admin_keep</allow_active>  Replace auth_admin_keep with yes 2. Save the file, and reboot your system. Now, you could easily mount your harddisk partition without password.  

So far, KDE Plasma is one the most mature desktops in Linux. It is simple, good loking, and has a lot of features. Even Windows 11 now looks very similar to KDE Plasma --make us wonder, has Linux desktop finally inspired Windows? However, some users might feel that KDE's default configuration is not fast enough. For those who want a responsive, blazing fast KDE desktop, here are some easy tweak to speed up your KDE Plasma 5 Desktop. 1. Disable Desktop Effect Go to Desktop Effect setting, and disable (uncheck) all effects. 2. Increase Animation Speed Go to General Behavior setting, and set the Animation speed to instant.  3. Disable Plasma Search KDE Plasma comes with a feature called Plasma Search. This feature offers us a complete set of desktop search, from applications shortcut to internet bookmarks. By default, all options are enabled and might slow down your KDE desktop. If you don't want to search your internet history on your desktop, and other unnecessary searches, y...

Termux is a cool terminal emulator that make it possible to run Linux environment on any Android device. However, when the first time you attempt to install an app by using pkg install command, you might find an error something like this: Metadata integrity can't be verified, repository is disabled now. The error is caused by the default Termux repo isn't accessed through your connection (that what I believe). Here is the simple workaround to fix the issue: Execute this following command: termux-change-repo There will be an option to change the termux repo. Tap OK on main repository, and select different repository available. In my case, I changed to the second repository (AlbatrHosted) and worked on my device. After that, try again to install a package by typing this command: pkg install [package_name] That's it.

There are a lot of great Linux distributions with their own special purposes and niche. But I can't deny that Ubuntu is special because it's the first distro I have managed quite well. One of the best thing about Ubuntu is the support for their older, EOL repository. If you are interested to dig to older apps to run on your newest Ubuntu system, you could still use their old release repository. With the current technology called AppImage, you could safely build and run an old app, fetched from Ubuntu old release repository. Here are the Ubuntu's old-release repository you could use: deb http://old-releases.ubuntu.com/ubuntu/ CODENAME main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ CODENAME-updates main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ CODENAME-security main restricted universe multiverse Replace CODENAME with the Ubuntu version you desire to use. For the detailed Ubuntu CODENAME releases, you could refe...

Chromium Browser is the parent of a lot of modern browsers. It is the base of the most used Google Chrome. There are also Brave Browser, Vivaldi, Opera, Microsoft Edge and Falkon, built upon this open source project. Most of those browsers offers us sophisticated features, but basically we crave for a clean, sleek, blazing fast web browser to explore the internet. For this ultimate purpose, Chromium Browser would serve you the best performance. Despite Google has decide to remove the Google synchronization feature, people still find Chromium as one of the best, most practical browser to use. Good news, you can download and try the fresh, newest Chromium Browser on your Linux machine (or Windows and Mac). Installation 1. You can download the Linux binary directly from Google repository at this following page: https://download-chromium.appspot.com/ 2. Extract the archive. There will be chrome-linux folder. 3. Run the binary by clicking it chrome-linux/chrome Performance Every vanilla ver...

Inkscape 1.2 has been released. It brings great, long awaited new features, like multiple pages and others. Unfortunately, when I try to install it from its official Inkscape Stable PPA, I got an error like this: dpkg: error processing archive /var/cache/apt/archives/inkscape_1%3a1.2+202205241504+da316b6974~ubuntu22.04.1_amd64.deb (--unpack):  trying to overwrite '/usr/lib/x86_64-linux-gnu/lib2geom.so.1.1.0', which is also in package lib2geom1.1.0:amd64 1.1-2build1 dpkg-deb: error: paste subprocess was killed by signal (Broken pipe) Errors were encountered while processing:  /var/cache/apt/archives/inkscape_1%3a1.2+202205241504+da316b6974~ubuntu22.04.1_amd64.deb From the error message we know that Inkscape 1.2 package comes with lib2geom library and so conflict happens with lib2geom1.1.0 package installed on my Ubuntu 22.04. This hapens because I've already installed Inkscape 1.1 from Ubuntu default repository. If you have Inkscape 1.1 installed on your Ubuntu 22.04, you pr...

In a very odd situation, sometimes, we need to use a custom binary application to run on our Linux system that doesn't exist in any repository. Let's say, for example, we want to try and install the latest nightly build of Firefox Web Browser. Traditionally, you can easily extract and execute the binary manually by clicking it. But how about install it locally on your user desktop menu? It is easy to "install" your custom binary on your local user folder.  As an example, I want to make the shortcut for Firefox Nightly on my user menu. Here are the steps: 1. Download the binary You can download the latest Firefox binary from its official web page. The binary is compressed as .tar.bz2 format. 2. Extract the binary Using your favorite file manager, right click at the .tar.bz2, and choose Extract. You will get a folder named firefox . 3. Install on your home directory Either use file manager or by command line, put the extracted folder firefox into /home/user/.local/bin ...

Yesterday, I experienced a very odd error in my new installed Rosa Linux R9 : the dig command not working ! Every time I tried to dig or dig ns a domain, there is no result.  I reconnected the internet connection, I rebooted the OS, but the result was still same. I didn't know whether it is the distro issue or not, but I've finally found the solution. Here are the steps : Edit /etc/resolv.conf sudo vi /etc/resolv.conf Replace the default record with these records : nameserver 8.8.8.8 nameserver 8.8.4.4 Make the resolv.conf immune so the network-manager can't automatically replace it sudo chattr +i /etc/resolv.conf Done

Google Chrome running on Solus OS Solus OS is a brand new, independent Linux distribution that comes with its own package management called eopkg. Unfortunately, there is no Chromium Browser yet in Solus' default repository. Also, Google Chrome only supports RPM dan DEB package. And so, how to install Chromium/Google Chrome web browser on Solus OS? There are two choices you can pick. (Personally, I prefer to "install" Google Chrome). 1. Chromium .Appimage You could use Appimage version of Chromium Browser that can be download from THIS REPOSITORY . After you downloaded the appimage file, make it executable by command chmod +x file_name. Last, install the dependecy : sudo eopkg install gconf 2. Google Chrome Chromium's .Appimage lacks Google account login so you can't access your synchronized bookmarks and histories from your another PC. Alternatively, you can use Google Chrome by a simple tricks as follows : - Download Google Chrome stabl...

KDE is one of the oldest desktop environment in Linux. While GNOME (the other desktop that as old as KDE) is trying to built its own style of user interface, KDE from the beginning seems to mimics the Microsoft Windows' "classic" user interface. Thus, KDE has its own user base, especially for them who still in love with the Windows' philosophy : a simple desktop, with a single taskbar in the bottom, and a start menu in the left. Personally, I love KDE. It's gorgeous and eyecandy. But sometimes, I feel KDE is little bit slow in my older hardwares. So, after some experiences, I've found some tweak how to make KDE Plasma Desktop Runs Faster . 1. Change The Compositing Engine  Go to System Settings>Desktop Effect>Advanced , and change the Compositing type from OpenGL 2.0 to XRender. 2. Remove All Bloatware Apps There are some uneeded apps installed in Kubuntu (my favorite KDE distro) and you could safely remove them. Here are my list : ...

GIMP 2.8 is good, but personally I have some issue with it and I still prefer GIMP 2.6 instead. Sadly, I’m not yet understand how to do some Linux programming to fork GIMP 2.6 into another app with different name. Fortunately, there is still a way to install old GIMP 2.6.12 onto new Ubuntu 16.04 Xenial Xerus. Here are the tips to safely install GIMP 2.6.12 on Ubuntu 16.04 Xenial Xerus and I’ve successfully tested it onto my Ubuntu 16.04.1 LTS Xenial Xerus. INSTALL THE DEPENDENCY First, install the dependency for GIMP 2.6.12 called libwebkitgtk-1.0-0 : sudo apt-get install libwebkitgtk-1.0-0 USE PRECISE REPOSITORY Change your sources.list repository from xenial into precise : sudo gedit /etc/apt/sources.list Replace all ‘xenial’ word to ‘precise’ Update your apt : sudo apt-get update Last, install the package : sudo apt-get install gimp UPDATE ISSUE After you’ve successfully install GIMP 2.6.12, revert your sources.list back from precise to xenial, and...

In Nautilus 3.4, Nemo, or Caja, there is a very useful menu called "Connect to Server". This menu allow us to connect to a Windows Share network via Samba. If you are using another desktop environment such as LXDE, there aren't such menu, and we need to install third party tool called Gigolo . But apparently, PCManFM (the default file manager of LXDE) already has such function. We could connect to a Windows Share network in PCManFM easily. Here are the simple steps : 1. Open PCManFM and go to adress bar, and type this command : smb://username@server/folder example : smb://staff@192.168.1.69/document then press Enter 2. Once you will be asked to input the Windows Share Network password (if exists), select Remember Forever option. 3. You are connected to Windows Share Network ;)

OGG is a common, widely used, and the default audio format in Linux. But sometimes, maybe you need to run your OGG collections in an old MP3 player. If so, there is a great tool called ogg2mp3 that can be used to convert massive OGG files into MP3 in one single process. Download You could get the .deb of ogg2mp3 in its Google Code page . This script depends on lame, so you need to install lame first : sudo apt-get install lame . Usage 1. Go to the path where your ogg collections located 2. Run the following command : ogg2mp3 *.ogg *.mp3

PHP selector is an awesome feature in RHEL/Centos/CloudLinux based web server. This feature allow user to select their own need of PHP version. Why do people need different version of PHP? Some need old version (5.2), and some need the newest version. Today, there are many web scripts (CMS) exists. Some CMS depend on older version of PHP, and some depend on newer, even newest version of PHP. Because of this trend, PHP Selector created. But for now, this feature is only dedicated for RHEL-based distros. So, if you are running other distros (such as Ubuntu server), this tool isn't available yet. Here are the steps to activate PHP Selector in cPanel : 1. Install cagefs # yum install cagefs 2. Install alt-php # yum groupinstall alt-php 3. Go to WHM, and find CageFS menu. 4. Enable the user you want to be PHP selector active by move from right box (Disabled) to the left box (Enabled).  Then, click Enable CageFS Skeleton . 5. Go to cPanel, and find Select PHP Vers...

Apport is a great apps in order to report any crashed app occurred in our Ubuntu system to the developers (theoretically). But just like any "notification" apps, this tool mostly go too far and become captious and madly annoying. It seems the apps will be awoken every time there is an app got a tinny, microscopic malfunction. And so, how to get rid of Apport so you can be as productive as usual ? If you are using Ubuntu 12.04, you just can easily remove the apps by command sudo apt-get remove apport . But if you are using Ubuntu 14.04 and higher, removing apport packages will break your entire system. Therefore, the only way to shut the apport up in Ubuntu 14.04 (and higher) is by delete the executable file.  Command : sudo rm /usr/share/apport/apport-gtk Reboot the system, and now apport gone for-ever. Goodbye Apport. Sayonara .
