The symptoms are pretty much similar to this question here, but with slight differences. 

LSB Version:    core-9.20170808ubuntu1-noarch:printing- 9.20170808ubuntu1-noarch:security-9.20170808ubuntu1-noarch
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.2 LTS
Release:    18.04
Codename:   bionic

I'm running an Asus computer with 2 os (win 10, ubuntu), but i almost never use windows. Sometimes, while I'm browsing or working on ubuntu, the computer starts to fail.

First of all, all the icons on the launchbar and dashboard disappear (expect, for some unknown reason, for the Qt Creator icon). no_icons

In this state, the terminal is no longer working, meaning that any command (sudo,cd,ls,etc.) ends up in an error. The keyboard shortcuts do not work anymore. If I try to lock screen and then reopen it, I lose the right to access. no_access

After few minutes, the monitor changes into the following screenno_os and all I can do is hard reset. Alt+Ctrl+F* does not let me change into another command line and Alt+Stamp+K do not reset the os.

Any help? Have you any idea on what could be the cause?

The "read-only file system" indicates that Ubuntu had a problem with the disk, and unmounted it and then remounted in read-only mode, as described in https://askubuntu.com/a/197468/283721

You should boot a live USB and run fsck on the disk in question, and you might also check the disk connections, and test the hard disk for errors, as described in How can I check the SMART status of a SSD or HDD on current versions of Ubuntu 14.04 through 18.10?
