I was previously using ubuntu, recently switched to ubuntu-mate.
The computer suddenly hangs and my only option to force shutdown by power button.
I was not having this problem in ubuntu , now that i have switched to ubuntu-mate I am having this problem.
I don't know how to even start solving this problem.
I have heard there are logs where we can find info, but no idea how to use it.
Any help appreciated.
When you say you have "switched" to Ubuntu Mate, do you mean you have done a fresh install of Ubuntu Mate or that you have installed the Ubuntu Mate Desktop onto an existing Ubuntu installation?
Hello and welcome!
Actually, I'd like to join to @skyraider256526 's question for my laptop with UM 18.04 suffers hangs/freezes as well. Yesterday it did that twice.
The only (unreliable) clue is that freezing occurs when I'm typing/working with a 'heavy' web single page application like @ UM forum or gitlab.
An advice on how to diagnose the problem and find out its roots is highly appreciated.
Regards,
Gene
yes i have done an fresh install

In my apport log there was error regarding msd-locate-pointer.
What was yours.
Alas, I've failed to find a mere trace of the problem in my logs.
what version of UM are you on please?
In case its GPU versus shared memory versus low RAM how about you post your

Are there any sensitive info there which will put my system at risk, like above command displays my MAC address.
since i have disabled the mouse pointer locater feature, system has not freezed.
If the it still freezes will let you all know.
Yeah that probably was the issue, I enabled it on Ubuntu Mate 18.04 which has mate version 1.20, and locate pointer option wasn't working and I used to get lots of crashes with msd-locate-pointer on the appport log. Tried a 19.10 daily build, which is using mate 1.22 and the locate pointer works fine without any hangs/crashes. So looks like it got fixed there.
