This quick tutorial shows how to get Mac OS style auto-resize dock launcher in Ubuntu 18.04, without installing extensions, e.g., Dash to Panel or Dash to Dock.
The left panel in Ubuntu 18.04 is called “Ubuntu Dock“. It is forked from Dash to Dock extension and less customizable via System Settings. There are only auto-hide, panel position, and icon size settings.
To get more settings for Ubuntu Dock, there’s a graphical tool called Dconf Editor.
1. First search for and install dconf editor from Ubuntu Software:
2. Launch dconf editor, and navigate to org/gnome/shell/extensions/dash-to-dock. And turn off the switch for ‘extend height’.
Then you’ll see an auto-resize Mac OS style dock launcher instead of the extended panel.

Linus Torvalds announced the released of Kernel 5.0 yesterday afternoon. He wrote on lkml.org:
Ok, so the last week of the 5.0 release wasn’t entirely quiet, but it’s a lot smaller than rc8 was, and on the whole I’m happy that I delayed a week and did an rc8.
It turns out that the actual patch that I talked about in the rc8 release wasn’t the worrisome bug I had thought: yes, we had an uninitialized variable, but the reason we hadn’t immediately noticed it due to a warning was that the way gcc works, the compiler had basically initialized it for us to the right value. So the same thing that caused not the lack of warning, also effectively meant that the fix was a no-op in practice.
But hey, we had other bug fixes come in that actually did matter, and the uninitialized variable _could_ have been a problem with another compiler.
Regardless – all is well that ends well. We have more than a handful of real fixes in the last week, but not enough to make me go “Hmm, things are really unstable”. In fact, at least two thirds of the patches are marked as being fixes for previous releases, so it’s not like 5.0 itself looks bad.
…
Changes in Linux Kernel 5.0 include:
AMD Radeon FreeSync support
Logitech High Resolution Scrolling support
Raspberry Pi Touchscreen support out of the box.
New console font for HiDPI and retina screens.
Initial support for NVIDIA Turing GPUs
And numerous other changes
