I have an old HP Pavilion dv9000 laptop and at the moment Manjaro KDE is running awesome.
But i had a very hard time to install KDE Plasma. XFCE is the only flavor that can be installed without issues. This is in fact a general Linux 5.xx problem for many distros.

Even with XFCE it is absolutely necessary to go back to kernel 4.19. Otherwise LibreOffice and Firefox will crash or freeze instantly the whole system.
I could boot the KDE live system only when setting some options:
After installing Manjaro KDE successfully.
At boot i had to press E and edit the kernel line, adding ¨3¨ to the end of that line, since the KDE environment simply did not start and freezes every time in the Plasma splash screen.
After booting the into a command prompt and login i was able to update the system.
sudo pacman -Syu
Then i had to change to the older kernel 4.19.
sudo mhwd-kernel -i linux 4.19
After reboot. Advanced choice and selecting the 4.19 kernel, i removed the 5.13 kernel, using Manjaro Settings manager.
KDE Plasma is now running, but still there was an issue with Firefox.
I had to start Firefox in the safe mode, from a terminal command prompt.
Then remove the hardware acceleration in the general settings, Performance of Firefox.
In the end i do not use Firefox anymore, but use Opera now.
LibreOffice is running okay so far.
I have seen a question like this before, but ask this again:
Would it be possible to supply a Manjaro flavor (of Gnome and KDE) with the older kernel 4.19, or at least with a possibility to select the older kernel, before booting the live system and during installation?
