From OSX (or Windows) to Linux Kubuntu

So i had had it with MacOS (keyboard butterfly problems, Catalina hanging...). Time to try something different. And since most of my colleagues use some Linux flavor, i opted for Kubuntu (at moment of writing v19.10, not on my Mac, on a Dell Latitude 7400).

This blog post contains some of the things i ran into, options i choose etc. For myself, but maybe for others as well.

Some of the choices i made etc:

• for synching with cloud storage platforms:
• am using an OwnCloud implementation (SURFdrive), so installed that
• for Dropbox, i'm using the official Dropbox Linux client (nice: a Dropbox-icon shows whether your files are in sync. Too bad: this client only support Ext4 as file system) 
• for Google Drive and OneDrive, after trying other solutions first and spending far too much time trying to find a sufficient working config, i eventually caved and decided to spend some money on InSync, which works great. The other clients for instance lacked clear status notifications about sync problems
• for Google Drive i tried OverGrive (also shows a sync icnon in your tray) 
• i was using OneDrive. Microsoft doesn't supply a Linux client (why not?), so found a couple, paid and free, and decided to go with a command line version
• this Onedrive client doesn't give you an icon showing whether files are in sync, so you have to check periodically whether it's synching
• (i also tried RClone, but found out it didn't do two way sync, which is a must for me, so gave up on RClone)
• for media streaming ended up with Kodi, after trying Plex (which i could not get working with my Samsung TV)
• i installed VirtualBox for when i need to keep file 100% compatibility with typical Microsoft files: installed Windows10 and Office2019. VirtualBox Guest Additions enable sharing folders and clipboard between host and guest OS
• i wanted to be able to access my data from both my Linux boot as well as when booting from Windows, so opted to put my data on a separate partition which i formatted using NTFS . So had to direct above cloud storage sync clients to store the data on that Data partition. With the official Dropbox client, this doesn't work, since it only supports EXT4.
• i had problems where my Wifi would drop / disconnect / not connect. Eventually i found this where i read by default Kubuntu changes the Mac address for privacy reasons, which might have caused the problem
• i really often missed an annotation tool, to add a box, oval, arrow, text etc to a screen shot or something. This thread lists some possibilities.
