How to Enable Dark Gnome Shell Menus, Calendar in Ubuntu 20.04

Last updated: April 6, 2020

gnome shell

Ubuntu 20.04 introduces new dark mode in the Settings utility. It is however not full dark when you turn it on in Gnome Shell.

System tray menu, top-bar calendar, notification popups, and desktop context menu are not dark but always light when you switching between light, dark, and standard modes.

Enable Full Dark Theme in Ubuntu 20.04:

1.) First install user themes Gnome Shell extension.

It was able to install the extension simply via Ubuntu Software when I was in Ubuntu 18.04. Ubuntu 20.04 however shows me “No Application Found” when I searching for user themes in the new Ubuntu Software (Snap Store).

  • As a workaround, open Firefox web browser and go to https://extensions.gnome.org:

    Click the link text “click here to install browser extension” and follow the pop-ups to install the browser extension:

    shell browser extension

  • Then open terminal via Ctrl+Alt+T and run command: 
    sudo apt install chrome-gnome-shell

  • Finally go to https://extensions.gnome.org/extension/19/user-themes/.

    Turn the switch on and then select install the Gnome Shell extension:

    User Themes extension

2.) Install Gnome Tweaks if you have it.

sudo apt install gnome-tweaks

3.) Finally launch Gnome Tweaks and navigate to Appearance in the left pane, choose Yaru-dark as the Shell theme and done!

And of course select Dark in System Settings -> Appearance to get dark applications if you don’t have it.

Fix unknown filesystem type ‘exfat’ in Ubuntu 18.04

Last updated: April 5, 2020

ubuntu bootable usb

Today when I plugged my new USB flash drive into Ubuntu 18.04 laptop, I got an error pop up that said ‘Unable to access “125GB Volume”. Error mounting /dev/sdb1 at /media/xxx/xxx: unknown filesystem type ‘exfat’‘

After a little search on the packages.ubuntu.com, I found Ubuntu main repositories offer exfat-fuse to read and write exFAT driver for FUSE, and exfat-utils to create, check, label and dump exFAT filesystem.

Open terminal either by pressing Ctrl+Alt+T on keyboard or by searching for ‘terminal’ from application menu.

When terminal opens, run command to install the two packages:

sudo apt install exfat-fuse exfat-utils

Once installed successfully, Ubuntu 18.04 should mount exfat USB drive automatically next time you plugged it in.

Last updated: April 2, 2020

QQ for Linux, the popular instant messaging apps developed by Tencent, released the second Beta on April Fools’ Day.

The development of QQ on Linux is quite slow. It has been 5 months since the last release. QQ for Linux 2.0 Beta 2 features:

The new beta now is much more stable than the first release, though it so far only supports for sending texts, emoji, files, and taking screenshots.

How to Install Kernel 5.6 in Ubuntu / Linux Mint

Last updated: March 30, 2020

upgrade Linux Kernel

Linux Kernel 5.6 was officially released. Linus Torvalds announced:

So I’ll admit to vacillating between doing this 5.6 release and doing another -rc.

This has a bit more changes than I’d like, but they are mostly from davem’s networking fixes pulls, and David feels comfy with them. And I looked over the diff, and none of it looks scary. It’s just slightly more than I’d have preferred at this stage – not doesn’t really seem worth delaying a release over.

So about half the diff from the final week is network driver fixlets, and some minor core networking fixes. Another 20% is tooling – mostly bpf and netfilter selftests (but also some perf work).

…

Linux Kernel 5.5 features WireGuard VPN support, and a lot of other notable improvements, including initial USB 4 support, Amazon’s Echo smart speaker, new Intel, AMD, and Arm hardware enablement.

How to Install Linux Kernel 5.6 in Ubuntu:

The mainline kernels do not include any Ubuntu-provided drivers or patches. They are not supported and are not appropriate for production use

The mainline kernel packages for Linux 5.6 are now available for download at the link below:

Download Kernel 5.6

Depends on your OS type, download and install the packages in turns:

  1. linux-headers-5.6.0-xxxxxx_all.deb
  2. linux-headers-5.6.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.6.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  4. linux-image-xxx-5.6.0-xxx-generic(/lowlatency)_xxx_amd64.deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, or armhf, arm64, etc for other OS types.

Alternatively you can download and install the kernel binaries via terminal commands ( open terminal via Ctrl+Alt+T):

For 64-bit OS:

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6/linux-headers-5.6.0-050600_5.6.0-050600.202003292333_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6/linux-headers-5.6.0-050600-generic_5.6.0-050600.202003292333_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6/linux-image-unsigned-5.6.0-050600-generic_5.6.0-050600.202003292333_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6/linux-modules-5.6.0-050600-generic_5.6.0-050600.202003292333_amd64.deb

sudo dpkg -i *.deb
