Thanks to dolphin_oracle for pointing out this simple task for reducing RAM usage in XFCE.
If you see a warming exclamation point to the right of an icon set in XFCE’s Appearance > Icons window here’s a an easy fix. Simply open up the terminal and run this command. This will cover all icons used in Peppermint or downloaded from a repository.
sudo update-icon-caches /usr/share/icons/*In cases like the screenshot below, an icon set is stored in the user’s directory.
$ gtk-update-icon-cache /home/USERNAME/.icons/ICON-SET-NAME/
Log out and back in, you’ll notice a reduction in RAM and a slight improvement in menu responsiveness.
Far more useful to highlight memory rather than CPU in your screenshot – then all can see the heavy mem usage culprits – XFCE…! Expect less than half of RAM usage with LXDE…
Anyone will confirm this is true.
Good point but these days I think we are gearing towards medium weight… :-)
