Blurb: “Stacer is an open source system optimizer and application monitor that helps users to manage an entire system with different aspects; it’s an all-in-one system utility.”
When it comes to cleaning up your Ubuntu desktop, we usually turn to the command-line. There have been tools in the past, but they did not seem to last. Stacer is one of those tools, designed for Ubuntu, but can be used on other distributions as well. Though it is built on the electron framework, it is not slow at all. You can get Stacer in a variety of options like direct .deb-file download, adding a PPA, or just grabbing an AppImage. Just remember to make the AppImage executable or it will open with your archive mounter. When you launch Stacer for the first time, you will see a very modern looking application. Menus are down the left hand side, and the name displays at the top.
Stacer opens with a handy dashboard.
The window is immutable, you cannot resize it, so it is rather small on your 1440p monitor and rather large on your 1366×768 laptop display. It minimizes neatly to the tray though, and you can actually use it from there. It also integrates nicely with docks like plank.
The rocket is the startup applications control. From here it is as easy as flipping a toggle to turn startup applications on and off. The next icon down is the broom. This is probably the most used tab. By default, nothing is selected and, to start cleaning, you need to select one or more of the categories. Generally, selecting “all” and running a clean is considered safe. The gears are the services tab; you can use this to turn off services like say, bluetooth, that you do not use. There are two toggles here, the first being the starting status and the next, the running status. The processes tab is a nice “top”-type overview, that allows you to only end a process. Clicking on the cyan text will sort the columns – just like top or htop. The ‘CD in a box’ tab is the installed packages; very handy to find something you do not need any more, but use it with caution! In previous versions, Stacer did not list base packages, so noobs do not brick their systems, but that has changed and it is possible to uninstall something like ACPI.
The bars and graphs are informative only. The nice thing about this tab is it provides you not only with current usage of system resources, but history too. If you are running Xubuntu, this is a nice way to get gnome-system-monitor without the install. H close box is your repositories, and again it makes it as easy as flipping a toggle to turn these on or off. The little Gnome foot is Gnome settings, and can be ignored if you do not run Gnome. The settings tab has a few settings, but not anything really important. All these are available from the drop-down menu if you minimize Stacer to the taskbar.
Stacer does nothing that cannot be done on the command-line, but brings it all together in one neat package.
If you have a small SSD, it is wise to consider adding the PPA or downloading the .deb-file as the AppImage is rather large.
Final thought, though Stacer is already a great tool, it would be nice if it did a bit more, like finding large files, duplicates, or files not used in say, a year. This would really help one clean out the system.
