I left Linux around 8 years a go, now I want to go back to it. I installed Ubuntu 16.04.2 as dual boot on MSI Leopard ge62 6QF. It wasn't booting before adding

acpi=off 

after quiet splash in the kernel line of GRUB. After this it boots successfully. Now when I wanted to reboot/Poweroff the system, I opened the terminal and wrote:

sudo reboot

It starts rebooting but it is freezing when it gets to

Reboot: Restarting System

I tried all Google suggestions like replacing acpi=force and decreasing the timeout but unfortunately none of them worked and the system doesn't boot anymore.

What else can I do?

  • Preferably install the current 17.04. No parameters should be required. Install the recommended Nvidia drivers at Additional Drivers and everything should work as expected. – user692175 Jul 30 '17 at 14:34
  • should i change something as acpi ? the current acpi is off should i remove it or what ? should i install 17? or 16 lts is fine – Basil Battikhi Jul 30 '17 at 14:37
  • As I said, with 17.04, no parameters. There are reasons for keeping a LTS in many situations. For high end and relatively new hardware, newer is always better. – user692175 Jul 30 '17 at 14:39

    i did read about what the meaning of LTS, it does mean long term support right ? that is why i want to keep the current LTS but no problem i will install 17 thank you :) – Basil Battikhi Jul 30 '17 at 14:41
  • Good luck with the next version with long time support, 18.04 LTS :-) – sudodus Jul 30 '17 at 16:56

Your laptop has the Intel i7-6700HQ 6th generation CPU known as "Skylake". It also has a NVidia Geforce GTX 970M GPU. To eliminate the dedicated Nvidia GPU from the equation you can temporarily work with only the integrated Intel GPU in the short term.

When using Skylake you made need updates:

These are some of the answers I've written but there are many great answers others have written:

Unfortunately not enough is known about your specific problems to point your question as a duplicate of an existing one.

One last thing to change is the Intel c-state max idle:

Although targeted at Intel BayTrail users it seems to have improved things for other Intel CPU users as well. If these fixes work I regard them as a work-around to make life better in the short term until a real solution is found.

  • Yes Already did it and you are correct – Basil Battikhi Jul 31 '17 at 11:25
