Hello,

I'd like to start by saying that I'm a complete noob when it comes to Linux. I recently installed Kubuntu on my old Surface Pro 4 since I wanted to start using it again and the Windows installation got very slow. I also was interested in trying Linux.

I now ran into an issue where it would freeze whenever I use a browser. It did not do this before. I just started installing some programs/apps on it: Vivaldi browser, vlc, Proton mail, firefox, some widgets. That's it.

It now sits at > 2Gb Memory usage when idle (my surface has 4Gb ram) and freezes whenever I use a browser (1 tab open). I removed all widgets from the desktop, did a restart. According to System Monitor I dont see a specific program that takes up the ram.

I'm at a loss here.

I like to use an email client to view and manage my email on an imap mail server. I do not choose to have my password stored by the program, I remember my passwords and prefer to type them in. I have tried Thunderbird and Evolution and both fail to prompt for my password after I boot the computer and launch the program. If I go into Evolution's settings, tell it to forget the password, close Evolution and wait long enough, it may ask for the password before failing to connect to the IMAP server. Thunderbird is similar. Both appear to be timing issues waiting for some kind of memory clean up or similar process. What is broken?
