Ubuntu Mate keeps freezing

Question

My computer recently started freezing a lot. The freezing affects everything but the power button. Each time it freezes I have to restart my computer and this is really affecting my productivity. Thanks in advance. My question is how do I figure out what is causes the freezes and then fix that.

Answer 1

You can see resources utilization of CPU and RAM for each process by running on a terminal the command :

top

You can also check the RAM actually in use with this command :

free -tm

If when your computer freeze you can't check which process cause the problem with top you can according to this check the log with :

In a terminal :

tail -f /var/log/syslog

If you are running gnome, then you can check the logs using "gnome-system-log"

To launch a terminal according to this you can do :

• If you're running Unity: open the dash, type terminal, hit Return.
• If you're on the old style menus, Applications → Accessories → Terminal.
• Control + Alt + T.
• Alt + F2, gnome-terminal, Return.

After that you just had to type the command and hit enter.

When you run top there a 3 important column for you, each line in top represent a process .

1. At the middle you can see behind the %CPU the % of CPU in use for a process.
2. At the right of the %CPU you have %MEM which represent the ram.
3. And at the just right you have command which is the process name corresponding to the use of CPU and MEM .
