Only addition is the "Restore process" chapter.

Problem

Google Support makes it sound like you can only restore the backup on setup.

At setup, to restore your data, follow the on-screen steps.

This is about a drive with MBR/DOS partition table and a NTFS partition on which I accidentally overwrote the partition table with fdisk /dev/sdb and then pressing g (new GPT partition table) and w (write changes to disk).

Luckily, I still had a terminal open, where I had the partition table (from fdisk -l) printed before I created a new one that overwrote it:

Disk /dev/sdb: 931,51 GiB, 1000204886016 bytes, 1953525168 sectors

If you activate WhatsApp (verifying your phone number) while having a /sdcard/WhatsApp/Databases/msgstore.db.crypt12 file present AND have a WhatsApp backup on Google Drive, WhatsApp will claim to restore your Google Drive backup (with your consent), but it only restores the media files from Google Drive but at no occassion the msgstore.db.crypt12. It won't merge your local backup and the cloud backup databases!

With local WhatsApp media files it will only offer to restore the local backup at activation but not the one from Google Drive, hence the need for an empty /sdcard/WhatsApp/Media/ folder. But with a local chat backup, the Google Drive backup restore process just imports media only anyways.

Ways to get to the key file to decrypt the *.crypt12 DBs:

either access /data/data/com.whatsapp/files/key with root permissions
OR adb backup com.whatsapp and extract the key from the .ab file

I have extracted the key and found out that it's the same for all my devices (*I always tested wi

Problem

Plasmashell doesn't start automatically after log-in
[optional] Windows of applications of previous sessions are restored which indicates that kwin loads/starts and is working automatically.
Condition: Manually executing kstart5 plasmashell works as intended. If this is not the case, the solution will very likely not help you!

Solution

Open "System Settings -> Startup and Shutdown -> Autostart -> Add Program" and add plasmashell (manually write it into the text field in the dialog window). (File saved in ~/.config/autostart)

Cause

The old autostart file only had the content

	Desks are not being synced across Chromebooks
	Shelf (taskbar) can't be set/customized to only display open application icons from the same desk

	Fixed in ChromeOS 89:
	On Chrome session restore (e.g. after crash), restored windows are all being placed on the first desk (i.e. all other desks are empty)
	"When you reboot, your windows will restore to their previous desks so your workflow isn’t interrupted." - https://www.google.com/chromebook/whatsnew/

	Maximum amount of desks you can have is 4 (limit is hindering for categorizing)
	Was increased to 8 (I still sometimes reach this limit)
