thank you in advance for the support.
I short foreword, I do not know much about Linux and Ubuntu. I can make any effort to understand and increase my skill but you have to be patient enough to give me explicit information and command or I wouldn't be able to support your support
I am running Ubuntu 20.04.3 LTS
lately my system started freezing unexpectedly
I does not happen after a specific command or when I use a specific application
Mouse and keyboard become unresponsive.
Quite often, when the system goes on sleep mode (black screen) as for example after inactivity, cannot be waken up. Screen keeps black and no command unblocks the system
On both cases I can only switch the power off and on again
I have made many research online and tried some solutions like repairing the installation, starting with an older version of the kernel etc.
I have searched a lot online with no avail
Somewhere I read that a good thing would be register the log of events so that after restart, I can send the log to some expert that with discover which process is responsible for the freeze.
So first of all I should learn how to start that service and where the log is recorded, what is its name and if I can send it here for analysis
So please help me understand what are the preliminary steps I should take to provide valuable information for supporting
Thank you in advance
