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?
This is the intelligent input bus - is an input method framework for multilingual input. If you don't use any different keyboard layouts for ex. japanese /asian etc.
Try to disable it in System Setting -> Language (something like input method from ibus to none)
Try to
killall ibus-daemon
and tell us if cpu is still has a high load.Find where
ibus-daemon
is located./user/bin/ibus-daemon
or/user/local/bin/ibus-daemon
cd to the directory
sudo mv ibus-daemon ibus-daemon.bak
killall ibus-daemon
restart gnome
Alt + F2 then type 'r' in popup
and enjoy
