I just updated my ubuntu 19.04 to 19.10. Update was successful but the mouse now lags even when 2gb out of 4 are used for the ram and CPU use is also low. This never happened with the older version. Is there anything I can do other than downgrade or restore ?
Thank you very much
Update:
by using htop instead of cpu monitor, I figured out that 100% of cpu was used in lower priority by tracker-miner-fs. I used the following script:
echo -e "\nHidden=true\n" | sudo tee --append /etc/xdg/autostart/tracker-extract.desktop /etc/xdg/autostart/tracker-miner-apps.desktop /etc/xdg/autostart/tracker-miner-fs.desktop /etc/xdg/autostart/tracker-miner-user-guides.desktop /etc/xdg/autostart/tracker-store.desktop > /dev/null
gsettings set org.freedesktop.Tracker.Miner.Files crawling-interval -2
gsettings set org.freedesktop.Tracker.Miner.Files enable-monitors false
tracker reset --hard
Taken from Radu Rădeanu's answer to tracker-store and tracker-miner-fs eating up my CPU on every startup.
Now everything works like a charm.
