For a year now I'm dual booting OpenSuse Leap 15.6 with GNOME and Windows 11. I love that there are no trackers, that I have the chance to know what the system is doing, that I can support honest developers, the simple interface, how fast and reliable everything works. I would love to ditch windows for good. So, I hope you'll manage to point me in the right direction with some of my remainig issues

• I encrypted GRUB and all partitions in OpenSuse. I have a TPM v2 chip. Now, every time I want to access one such partition I need to first enter the root password. I'd like to have access to all my partitions after I unlock GRUB and log in to my OS. Is this something that has to be done in fstab, system.d or somewhere else? If you could point me to some resources, it'd be great!
• On Windows I'm using Total Commander to select multiple files, invert that selection, sync directories (meaning compare by content, size, copy from left to right, overwrite etc), pack and unpack archives, view, copy, move, rename files. I tried Krusader as a dual-panel manager, but I'm lacking the selection, sync features and it doesn't have the Gnome Look & Feel. If I install TotalCommander using Wine, I can't see the other partitions. Can you recommend a different dual-panel file manager or some way to make TotalCommander see all partitions?
• Some movies skip frames or stutter. I assume I'm missing some proprietary codecs. How should I check what's missing? I have an AMD RX 6600 XT and haven't installed any special drivers or codecs until now.
• When I shut down the computer I am logged out, the processes are killed, but then the computer hangs and I hear the fans working, but don't see anything on the screen. Any idea what logs I can tail or search to find what's triggering this or any ideas to fix this?
