Enable Hot Corner in Ubuntu 18.04
Hot Corner is a Gnome Feature that allows you to see all open windows (same as clicking Super key or clicking on Activites) by moving mouse to top left corner.

To see if hot corner is enabled or disabled, run
```
gsettings get org.gnome.shell enable-hot-corners
```
To enable hot corner, run
```
gsettings set org.gnome.shell enable-hot-corners true
```
EDIT: After using enable hot corner for a day, i found my mouse reach this corner accidetly multiple times. Seeing activites page unexpectedly when you want someting else is confusing. For Ubuntu, it is better to keep it disabled.

To disable, run
```
gsettings set org.gnome.shell enable-hot-corners false
```

Separate Google Hangout icon in Ubuntu 18.04/20.04
On Ubuntu 18.04/20.4, when you install google hangout plugin in google chrome, it shows samne as Google Chrome Icon. It act like you have opened 2 windows, it is hard to switch between as every time you click on Google chrome icon in side bar, it ask you to select which window to switch to.

On Ubuntu 16.04, it shows same icon, but windows won’t combine in side bar, so you can click them seperately. To make Hangout show differnt icon in Ubuntu 18.04, first find ID of Google Hangout plugin. Go to Menu > More Tools > Extensions.

You need to enable “Developer mode” to see Extension ID, this can be done on extension page top-right side.

In this cause, we found ID of Google Hangout Extension as “nckgahadagoaajjgafhacjanaoiihapd”. This can change, so always find ID of extension you have installed.

Now create a file (make sure you replace GOOGLE_HANGOUT_PLUGIN_ID with ID you found in step above).
```
vi ~/.local/share/applications/chrome-GOOGLE_HANGOUT_PLUGIN_ID-Default.desktop
```
Add following to the file
```
#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Terminal=false
Type=Application
Name=Gmail
Exec=/opt/google/chrome/google-chrome --profile-directory=Default --app-id=GOOGLE_HANGOUT_PLUGIN_ID
Icon=chrome-GOOGLE_HANGOUT_PLUGIN_ID-Default
NoDisplay=true
StartupWMClass=crx_GOOGLE_HANGOUT_PLUGIN_ID
```
Save and exit. Here is what i have on my computer.
```
boby@ok-pc-01:~$ cat ~/.local/share/applications/chrome-nckgahadagoaajjgafhacjanaoiihapd-Default.desktop
#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Terminal=false
Type=Application
Name=Gmail
Exec=/opt/google/chrome/google-chrome --profile-directory=Default --app-id=nckgahadagoaajjgafhacjanaoiihapd
Icon=chrome-nckgahadagoaajjgafhacjanaoiihapd-Default
NoDisplay=true
StartupWMClass=crx_nckgahadagoaajjgafhacjanaoiihapd
boby@ok-pc-01:~$ 
```
Now if you start Google Hangout, it will show as differnt application. But Hangout won’t show generic icon.

To get hangout show proper icon, right click and save following icon file

Rename it as “chrome-GOOGLE_HANGOUT_PLUGIN_ID-Default.png”. Make sure to replace “GOOGLE_HANGOUT_PLUGIN_ID” with your actial plugin id. In my case, the name of the file is “chrome-nckgahadagoaajjgafhacjanaoiihapd-Default.png”

Put the icon file in following location.
```
~/.local/share/icons/hicolor/128x128/apps/chrome-GOOGLE_HANGOUT_PLUGIN_ID-Default.png
```
Now restart your computer or restart Gnome Shell, you will have new shiny icon for google hangout.

Things to do after installing Ubuntu 18.04
Today i installed Ubuntu 18.04. Ubuntu 18.04 use GNOME desktop instead of Unity Desktop. I like some of the new features, but missed some feeatured i am used to in Ubuntu 16.04. First thing i notice was i can’t easy change sound output device like in Ubuntu 16.04, i expected Ubuntu 18.04 made it easier. But after spending some time, i found out i can customize Gnome to make it work like i need.

Show date in top bar

I want to show date along with time in top bar. To enable this, you need to install gnome-tweek-tool.
```
sudo  apt-get install gnome-tweak-tool
```
Now start gnome tweak tool, this is available as Tweaks

Go to Tweaks > Top Bar. Under clock, set “Date” to On.

Now you will see full date along with time.

Set time 12 Hour format

By default Ubuntu 18.04 show time in 24 hour format. I prefer 12 hour format with AM/PM.

Click on Power button, select Settings.

Go to Details > Date & Time

Gnome Shell Extensions

You can customise how GNOME work by installing extensions. This is just like google chrome/firefox extensions. Installing is easy.

First run
```
sudo apt install gnome-shell-extensions chrome-gnome-shell
```
Now open your web browser, visit

https://extensions.gnome.org

This will ask you to install a browser plugin, so you can install Gnome Extensions easily from the browser itself.

For Firefox, install plugin

https://addons.mozilla.org/en-US/firefox/addon/gnome-shell-integration/

Create an account in Gnome.org, so you can manage your extensions.

Here is some of the Gnome Extensions i installed.

Unite

Unite make your Gnome Top bar like Unity. Date get moved to right side. Also application close buttons merge with top bar like in Ubunty. This save from top space. This is highly recommended if you are a Unity user switching to Gnome.

You can install it from

https://extensions.gnome.org/extension/1287/unite/

Sound Input & Output Device Chooser

This Gnome Extension allow you to easily switch sound devices.

You can get it from

https://extensions.gnome.org/extension/906/sound-output-device-chooser/

Remove Totem

Ubuntu come with Torem video player. I perfer VLC. Remove Totem and install VLC with
```
sudo apt remove --purge totem
sudo apt install -y vlc
```
