My computer used to freeze all the time and to solve the issue i had to reset the computer because i use ubuntu which doesnt have a task manager and now it wont even start up what is wrong with it?

Answer 1

Ubuntu is very stable.

If one piece of software was freezing its clearly software problems. The rest of the screen outside that app's window would still work.

If everything was locking up I'd suspect a hardware error.

If you are hardware skilled try removing and re-inserting the memory cards.

There is also excellent task management in Ubuntu. Bring up a terminal window and shell, then

$ ps -afe | less

Find the process id of your mis-behaving program under the column labelled PID.

Then simply type

$ kill "insert process id number here"

or alternatively you can

$ pkill -9 "insert process name here"

$ exit

and your mis-behaving process will be dead, dead, dead...

Hmm. I should perhaps caution you here not to try to kill process '1', also called 'init'. If you wish 'init' to change it's runlevel, simply consult the 'init' man page and issue the appropriate argument to 'init'. Well, just be sure you kill the correct process or your mileage may vary (GREATLY!).
