Dolphin giving pain with MTP i.e. Giving error when trying to access files on MTP device (workaround, it will still give pain!)
Unplug device, close all all tabs of dolphin and then dolphin itself then run the following command
$ sudo udevadm trigger --action=change
Launch dolphin again.

After that add input method with Fcitx called Mozc. You might also want to enable global shortcut to switch input methods. I recommend using Super Key + Space key.

Tip: You can leave out most packages that you don't need.
I am not sure why this happens, it used to work fine before on same hardware. There are two possibilities, I replaced my screen and vendor probably installed a knockoff version on my machine, or Novell broke the installer (I am using tumbleweed edition). This probably can be worked around by passing resolution parameters in grub before the installer starts. See more, https://linuxhint.com/set_screen_resolution_linux_kernel_boot/
As soon you see your system booting after grub press "esc" button to see console, look out for password input prompt, as soon as you see it quickly press enter button and enter your password and press enter again. As soon as you can boot into your system run the following:
$ sudo nano /etc/crypttab
You will see a line something like
cr-auto-1 UUID=43a6aea6-94e5-47fe-b524-34fd1e969ee5
Add timeout option to the line, which will result in something like the following line
cr-auto-1 UUID=43a6aea6-94e5-47fe-b524-34fd1e258ee5 timeout=180
180 means seconds the system will wait for you to input your LUKS password

Visit https://mirrors.opensuse.org/ and choose a mirror, select either HTTP or FTP as a base URL. Copy it and visit it,
YaST > Software > Software Repositories
As you can see in GUI, you have to make repo URLs using the base URL of the mirror you just copied, so create the repo URLs with your base URL and also verify by visiting them using a browser. Then add them using the "Add" button. You may also need to accept terms and conditions when adding a repo. The default repo priority is 99, to make zypper prefer your selected repos you need to set their priority lower than 99. Trying zypper dup in terminal can also hint to you if your repos are hosting older software if zypper wants you to downgrade your packages. In that case, you have two options, you can either reselect another mirror or just keep the priority of the mirror the same as the default ones i.e. 99.
Below is an example of creating repo URLs from a base mirror URL http://ftp.kddilabs.jp/Linux/packages/opensuse/ :

Relabel files for SELinux if Desktop Environment does not let you login (This also happens when you reuse /home when install Fedora KDE Spin)
Add autorelabel option to your cmdline by temporarily editing grub entry. You can do that when you are on grub screen. Just highlight a kernel and press E button and add it to cmdline and save it by pressing Ctrl + X.
Usually OpenSUSE, Fedora and RHEL are known to do it automatically.
