This quick tutorial is going to show you how to install the classic style Gnome application menu in Ubuntu 18.04, and higher.

There’s a Gnome Shell extension called Gno-Menu. It is a traditional styled full featured Gnome-Shell apps-menu, that aims to offer all the essentials in a simple uncluttered intuitive interface.

Simply open Ubuntu Software, search for and install Gno-Menu.

Then you’ll see the new application menu in top-left corner. Click to expand the app menu, and click the gear button (see the top pic.) can bring up the settings dialog.

Gnu Emacs text editor 26.2 was released yesterday with a wide variety of new features. Here’s how to install it in Ubuntu 16.04, Ubuntu 18.04, Ubuntu 18.10, Ubuntu 19.04, and derivatives.

New features in Gnu Emacs 26.2 include:

  • Emacs modules can now be built outside of the Emacs tree source.
  • Compliant with the latest 11.0 of the Unicode Standard.
  • In Dired, the ‘Z’ command on a directory name compresses all of its files.
  • New toggle ‘ibuffer-do-toggle-lock’, bound to ‘L’.
  • The value for ‘imenu-auto-rescan-maxout’ increased to 600000.
  • Supports 24-bit colors on capable text terminals.
  • VC support for Mercurial was improved
  • And many other changes, see the changelog.

How to Install Emacs 26.2 in Ubuntu:

1. Open terminal either via Ctrl+Alt+T keyboard shortcut or by searching for “Terminal” from start menu. When it opens, run command to add the PPA repository:

sudo add-apt-repository ppa:kelleyk/emacs

Type user password (no asterisk feedback due to security reason) when prompts and hit Enter.

2. Then install Emacs26 either via Synaptic package manager, or by running following commands one by one in terminal:

sudo apt update

sudo apt install emacs26

For text-only interface, replace emacs26 with emacs26-nox in the last command. And Ubuntu 18.04 and higher can skip apt update command.

Once installed, open emacs from your system application launcher and enjoy!

How to Remove:

To remove Emacs26, open terminal and run commands:

sudo apt remove --autoremove emacs26 emacs26-nox

The PPA can be removed by going to Software & Updates -> Other Software tab.

For those sticking to the open-source RadeonSI / RADV / Intel / Nouveau drivers, the latest Mesa 19.0.2 graphics libraries is now available to install in Ubuntu 18.04 via PPA.

Mesa 19.0 was released a months ago with many features including Intel’s Vulkan driver transform feedback, soft FP64/INT64, RadeonSI FreeSync/Adaptive-Sync, AMD Zen thread optimizations, and more. Then Mesa 19.0.2 was released ago a few days with a handful of fixes.

Canonical’s Timo Aaltonen has made Mesa 19.0.2 package into “Ubuntu-X” team PPA for Ubuntu 18.04.

To get better open-source graphics driver performance, you may install Mesa 19.0.2 via following steps:

1. Open terminal either via Ctrl+Alt+T keyboard shortcut or from software launcher. When it opens, run command:

sudo add-apt-repository ppa:ubuntu-x-swat/updates

Type user password (no asterisk feedback) when it prompts and hit Enter to continue.

2. After adding the PPA, do system update via command:

sudo apt-get dist-upgrade

apt-get update is not required any more in Ubuntu 18.04 since adding PPA automatically refreshes system package cache.

3. Finally check your driver version via command:

glxinfo | grep "OpenGL version"

Uninstall:

To restore changes and downgrade to the default drives shipped in Ubuntu 18.04, run command:

sudo apt-get install ppa-purge && sudo ppa-purge ppa:ubuntu-x-swat/updates
