This quick tutorial shows you how to reset Gnome Shell to its original status in Ubuntu 18.04 LTS.
Note following steps will reset most settings to its original status in the default Gnome 3 desktop, but no guarantee of ALL Gnome appearances.
1. As you may already know, there’s a graphical tool Gnome Tweaks that allows to tweak advanced Gnome 3 settings. And it can be installed in Ubuntu Software:

If need, you can run command in terminal (Ctrl+Alt+T) to reset all the settings:
Linux Kernel 4.17 was finally announced yesterday. Linus Torvalds wrote in lkml.org:
So this last week was pretty calm, even if the pattern of most of the stuff coming in on a Friday made it feel less so as the weekend approached.
And while I would have liked even less changes, I really didn’t get the feeling that another week would help the release in any way, so here we are, with 4.17 released.
No, I didn’t call it 5.0, even though all the git object count numerology was in place for that. It will happen in the not _too_ distant future, and I’m told all the release scripts on kernel.org are ready for it, but I didn’t feel there was any real reason for it. I suspect that around 4.20 – which is I run out of fingers and toes to keep track of minor releases, and thus start getting mightily confused – I’ll switch over. That was what happened for 4.0, after all.
As for the actual changes since rc7 – the shortlog is appended – it’s mostly drivers, networking, perf tooling, and a set of nds32 fixes. With some random other stuff thrown in. Again, the shortlog is obviously only the last calm week, the overall changes since 4.16 are much too big to list in that format.
The big 4.17 stuff was mentioned in the rc1 email when the merge window closed, but I guess it’s worth repeating how 4.17 is actually a slightly smaller kernel than 4.16, thanks to the removal of a number of effectively dead architectures (blackfin, cris, frv, m32r, metag, mn10300, score, and tile). Obviously all the other changes are much more important, but it’s always nice to see spring cleaning like that.
…..
Linux Kernel 4.17 release highlights:
AMDGPU DC enabled by default for the new display code stack.
Intel Cannonlake graphics support enabled by default.
Improved AMDKFD support for pre-Vega discrete GPUs.
Clean up lots of code for obsolete CPU architectures
A significant power-savings improvement on some hardware
And many more other changes.
