FLAVOR: Ubuntu Desktop HEADLINE: Make the GUI stop hanging all the time? DESCRIPTION: This has been happening to me across multiple computers running Ubuntu for years. Even on a fairly current one, the Intel NUC5i7RYH, I'll be doing really trivial stuff and the entire system just hangs. Like, I pick up an icon in nautilus and the system hangs before I've even given it an instruction. 10 seconds later, the window ungreys and I can do stuff like move the file. Or I might click and hold on an email in Evolution to move it to a folder, and evolution entirely hangs for a long time before it lets me complete the action. It's really weird, and has been with me over two different computers and at least 4 years worth of Ubuntu distributions. I feel like I'm crazy and the only person who this seems to affect, because no one else ever seems to know what I'm talking about. Even weirder to me is that this never happened on older versions, on older hardware, yet no one else seems to have an issue. It's super frustrating.
