I've been trying for several days to install Manjaro (and before Ubuntu) on my MSI WS72 portable workstation. Everything seems to go smoothly and OK until we get to switching off the system. It always gets stuck there: the Manjaro desktop screen freezes and the only way to turn it off is by pressing the power button for 8 secs.
I've been going through some other similar topics in this forum and other Internet sources, but after hours of tests and different variations on the installation, I always get to the same.
Some system info:
$ inxi gives: CPU: Quad Core Intel Core i7-6700HQ (-MT MCP-) speed/min/max: 800/800/3500 MHz Kernel: 4.19.13-1-MANJARO x86_64 Up: 5m Mem: 910.2/15913.4 MiB (5.7%) Storage: 1.38 TiB (0.5% used) Procs: 205 Shell: bash 4.4.23 inxi: 3.0.28
THE POSITIVE CLUE
- It always works perfectly well from a Manjaro live session booted from the USB memory. It shuts down properly and all the issues reported following don't happen.
THE NEGATIVE CLUES
inxi -F freezes the terminal!!! and I have to get the cursor back with ctrl-Z
Also if I run the hardware configuration application, the window freezes before any contents are displayed in it, and when I try to force the window to close it says "kcmshell5" doesn't respond.
I tried adding "force acpi" in certain line of the grub, but after editing the grub file as told on the post, the system freezes when I do the grub update.
I've installed Manjaro in the three available "BIOS" modes: Legacy, UEFI and UEFI-with-CMS and I get the same problems from the installed version (not at the USB live session).
Regarding the NVIDIA graphic device and drivers, I can't change to "non-free" or do anything about this at the hw configuration application because it crashes as I explained. When running the USB live session, in legacy mode if I switch to driver=non_free at the welcome screen, the boot process gets stuck almost at the end of all those boot [OK] lines, but in UEFI mode the non free drivers can be chosen and the live session works well and turns off properly, but after installing it doesn't power off again.
If I create a test user, I get the same problem.
Any idea on what to do ??
Thanks in advance to you all for the work and support in this Manjaro community.
