Occasionally my desktop slows down a lot. The mouse pointer moves slowly or not at all, my fan starts whirring, and the end is generally nigh. If I'm very patient normality usually restores itself, but this happens daily.
Recently when it happened I switched to a TTY (Ctrl-Alt-F1) and ran top
. It revealed that the processes ibus-daemon
and ibus-ui-gtk3
were using 99% and 100% of the CPU respectively.
Maths notwithstanding, how can I find out what these processes are doing at the time?
