Partitioned by hand using the advanced options as there are multiple OS on this laptop and this qubes instalation which went into 70GB partition with ext4 format is for testing only.
Multibooting is not a problem thanks to grub which is on the machine due to kali.
Changed boot order in efi accordingly to boot the grub of the kali linux installation on this laptop. Update-grub of kali found qubes-os automatically. Using unencrypted qubes on ext4 partition as / for testing.
Qubes-OS-4.3 RC3:
Suspend to RAM does not work:
The screen is dark for longer time, and the screen gets lit only after mouse movement.
The build-in keyboard of the laptop does not work, so login into the lock-screen does not work.
I wish there would be a sync-button in the lock-screen as I had to hard switch-off the laptop (press power for longer time, the chipset then issues power-off)
