How To Install rtl8821ce-dkms on Ubuntu 22.10 and 22.04 LTS

WiFi card is a component you can't really choose. CPU, memory, graphic card and storage, are probably the main reason people buy a laptop, but not a WiFi card. It's just a tiny device you always think and expect to work without problem.

Today, almost any network device work out of the box under Linux kernel. If not, the proprietary firmware can be easily installed. Unfortunately, there are few issues with few WiFi cards in Linux. Realtek is one in the list.

I have a laptop with realtek 8821ce wifi card that always works properly on my Ubuntu machine. There is a package called rtl8821ce-dkms I can install directly from Ubuntu's repository and the wifi will work as it should. Sadly, this package is deprecated in Ubuntu 22.10 repository and doesn't work with Ubuntu 22.04's kernel 5.19 upgrade.

Apparently, there is already a module rtw88_8821ce included in Linux kernel. But this driver doesn't work properly yet. You have to be near your wifi router to be able to get the proper signal. If you move a little further, the signal will become weak and the connection will fail.

Installing rtl8821ce-dkms From PPA

Thankfully, there is a PPA for rtl8821ce-dkms package you can install into your Ubuntu 22.10 or updated 22.04 :

sudo add-apt-repository ppa:xalt7x/rtl8821ce-dkms

sudo apt update

sudo apt install rtl8821ce-dkms

Blacklisting Default Driver

After installing the package, you have to make a little next step to make it work as the default wifi driver:

sudo modprobe -r rtw88_8821ce

sudo modprobe rtl8821ce

sudo su

# echo blacklist rtw88_8821ce >> /etc/modprobe.d/blacklist.conf

Reboot the system.

Alternative Installation

There is also an alternative rtl8821ce-dkms package source you can install and should work in any Linux distribution. The detailed information and installation, you can follow in this following page: https://github.com/tomaspinho/rtl8821ce

The Future

Currenly, rtw88_8821ce is the default driver included in Linux mainline kernel. While it still doesn't work properly, we still hope in the future, this driver will work better and we don't have to do extra effort to make realtek 8821ce work properly under Linux kernel.

How To Speed Up Your KDE Plasma Desktop (KDE4)

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 : ...

Q4OS 4.6 "Gemini" Review: A Real Hidden Gem

Distro hopping is a fun adventure. It's a pure joy you can only find in GNU/Linux world. It's a nature you want to escape from what I call 'comfort ecosystem'. You need to play, trying something new even for a few little differences. For a long time I've been using Ubuntu family as my daily driver. The main reason is probably just same as any other Ubuntu user: it's reliable. You can't go wrong with Ubuntu. It works almost in any device, even for the newest one. It is the ultimate Linux distro you can rely on. However, sometimes, you will feel bored. The temptation to flirt with other new distro is unbearable. There are a lot of hot new Linux distros waiting to try. A Real Hidden Gem I've known this distro for a quite long time. At first, it offered Trinity Desktop as the main desktop, which brings me the sweet memories about KDE3. It is simply fast, stable, almost without any issue, and it is based on Debian. I install it on my old machine and I love t...

Download, Install and Play Angry Birds Rio In Ubuntu/Debian Linux

Angry Birds Rio is a spin-off of the new-legendary game Angry Birds. This plot is specially taken from popular animation film Rio, an adventure of a pet Blue macaw bird from US in Brazilian jungle. Based on that successful film, there are some game developers created a spin-off for Angry Birds game called Angry Birds Rio. The good news about this is, there is already a flash version of this game so we could play it in Linux desktop easily using flashplayer (standalone player, or by Internet Browser with flashplayer plugin). And just like what I've done before in Angry Animals game, I've packed this game too into Debian package so we could install it with ease. If you have had installed flashplayer standalone, you don't have to download and install it. But, if you haven't it yet, you have to download the flashplayer standalone to play this game. These are the packages : adobe-flashplayer-standalone-linux_10_i386_debian.deb angrybirds-rio_0.1_i386_debian.deb This is a fre...
