Me: ethernet, budgie, connected to internet, and just opened 4 apps double-clicking in menu, and 4 more apps thru terminal.
Wonder what the similarity between the first two in this thread are? Never heard of the phenomena...unless internet is just the 'red herring' and your cores are maxed out with apps and you have no swap?------(spittballin; 2 cents)
system settings in menu or terminal top/htop may reveal more.
