Ubuntu how to right click and scroll

I have not been using my Ubuntu laptop touchpad for ages, but recently i have been traveling and i am taking my laptop out every day, so i have to use the touchpad way more frequently.

A wrench got thrown in my thinking process when i saw i cannot right click or edge scroll but it looks like this behavior was just changed. If it’s simpler or not it’s for you to judge:

Right clicking in Ubuntu is now achieved by using 2 fingers to click on the touchpad.

Edge scroll seem to not be working anymore, however you can scroll by using 2 fingers instead of one, anywhere on the touchpad.

Happy Ubuntu-ing!

Ubuntu – close Discord but notifications still come

So i am using Discord a lot and i have encountered this problem more than once: you close Discord but the notifications still come even though the icon in the systray is not there. Pretty annoying right?

I found 2 cool things to deal with this:

1 – https://extensions.gnome.org/extension/1031/topicons/ – install topIcons Plus – this will show you the systray at the top and if you close any program from there, it really stays closed.

2 – press “control+q” while having Discord opened. – same result.

Enjoy!

Create MySQL Admin user

If you want to create a MySQL admin user that can connect from anywhere, feel free to tweak the string below:

#create SQL Admin user
CREATE USER ‘clusterAdmin’@’%’ IDENTIFIED BY ‘YOUR_cool_password_here’;
GRANT ALL PRIVILEGES ON *.* TO ‘clusterAdmin’@’%’;
FLUSH PRIVILEGES;

If you want to limit connections to localhost, switch the “%” to “localhost”

Google Cloud Platform – FTP

So if you’re getting an error similar to this: “500 I won’t open a connection to 10.142.0.9 (only to…” if you’re trying to use FTP on a VM on Google Cloud, fear not, it’s an easy fix.

You can do this 2 ways:

1 – FTP -p remote-host

or

2 – FTP remote-host -> log in -> then type “passive” without quotes, and everything should be just fine.

MySQL 5.7 – reset root password

So there’s been a change in the way you reset the MySQL root password in MySQL 5.7 as in the “password” field got removed, so the old way of resetting the password doesn’t work anymore:

| authentication_string | text | YES | | NULL | |

So let’s go:

1 – stop the mysqld:

systemctl mysqld stop

2 – start mysqld with skip-grant so it doesn’t ask for your password:

mysqld –skip-grant-tables &

3 – change the pw:

use mysql;

update user set authentication_string=password(‘yourNewPwHere’) where user=’root’;

flush privileges;

quit

4 – stop the mysql

5 – start the mysql with the new root pw

systemctl start mysqld

Enjoy!

Reset wordpress file/folder permissions

If you need a quick and easy fix for broken wordpress permissions - feel free to copy/paste the lines below. These will reset them to defaults.

cd /your/wordpress/folder
find . -type d -exec chmod 755 {} \;  # Change directory permissions rwxr-xr-x
find . -type f -exec chmod 644 {} \;  # Change file permissions rw-r--r--

So if you’re having some issues with SSL connections, it’s higly likely you’re experiencing them from client version openssl 1.0.2. the fix is below and i can confirm it works on both openssl 1.0.1 and 1.0.2.

openssl s_client -connect yourdomain.com:5671 -showcerts
