On my Ubuntu (Gnome) laptop, I often get a popup saying an issue happened when waking up computer.
I also sometimes had pain accessing an external drive, plug in, plug out, in, out... and finally it worked. Usually it works immediately, but not this time.
Recently I was looking to free space, I have old accounts in my /home (from previous installations of Manjaro KDE, Manjaro Gnome...) and found I had 150 GB in the Download folder of one of this accounts. I opened a video just to check its content, and explorer crashed. I restarted explorer, selected everything in folder, deleted and... explorer crashed again. I tried again and this time it crashed when selecting files... I finally succeeded, but what a pain.
I rarely turn off computer, just put it in sleep, I suppose this is why sometimes Firefox freezes for a few seconds after days without restarting, so I restart and everything is OK.
