I have bought a new desktop; it's an Asus VivoBook Pro N552VW. I installed Ubuntu 18.04 in dual boot with Windows 10. The system is working perfectly but it freezes during shutdown/reboot/suspend/hibernate. It also freezes in a singular situation: I succesfully login when I write the correct password on the first try, but if I fail at least one time, then when I write it correctly, it freezes as stated above.

These are PC's detailed:

  • Processor: Intel® Core™ i7 6700HQ Processor
  • OS: Windows 10 Home
  • Chipset: Intel® HM170 Chipset
  • Memory: DDR4 2133 MHz SDRAM, 2 x SO-DIMM socket for expansion up to 16 GB SDRAM
  • Graphics: NVIDIA® GeForce® GTX 960M with 2G/4G GDDR5 VRAM
  • Storage: 2.5" 9.5mm SATA3; 1TB HDD 5400 RPM; 1TB HDD 7200 RPM; PCIE x 4 256G / 512G



The system is fully updated using Update Manager.

  • How can I determine what is causing the freeze?
  • How can I fix this?



Initally, Ubuntu didn't power on, but adding acpi=off I could fix it. This rather didn't help me to resolve the shutdown.

I tried these things:

  • I tried adding Intel microcodes, but it didn't help.
  • I added quiet splash in GRUB-edit.
  • I did a lot of changes in GRUB-edit, but nothing brought me a successfully resolution.

After all these attempts, when I powered off my laptop, the typical written that came up was: Wlp2s0: failed to remove key (2, ff:ff:ff:ff:ff:ff) from hardware (-22) and reboot: System halted.

Then, yesterday I added nomodeset in front of quiet splash in GRUB-edit, and Ubuntu stucked no more when the writtens stated above came up, but one step ahead: it stucked at Ubuntu log.

Has somebody ideas? Thank you very much!

  • First thing that comes to mind is, try another distro..... Meant to be more helpful than not. Truly, some distros and versions of the kernel/ GUIS work different on different machines ime – Robert Sederholm Jul 5 '18 at 15:10

    I'n actually thinking that, if nobody can give me an answer, I'll try an other distro. Anyway thank you so much for interest!!! – giaco Jul 5 '18 at 23:30
  • I'd try Linux Mint, if I were you. It's basically Ubuntu, but they tweak it to their preferences. If that doesn't work, try an earlier release of Ubuntu or Linux Mint. – Robert Sederholm Jul 6 '18 at 5:39
  • Thank you for your help!!! I'll wait some day for a miracle ahahah, then I'll do it. – giaco Jul 6 '18 at 8:14
  • Stick with Debian or Debian based distros for netflix support! – Robert Sederholm Jul 6 '18 at 18:15

This worked for me - https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1756226/comments/20

Using Asus ROG GL752-VW, NVIDIA® GeForce® GTX 960M. Also currently using nvidia-driver-390 instead of Nouveau. Running dual booted Win10 and Ubuntu Mate 18.04.


I finally tried an older version: Ubuntu 16.04.4, and it works fine. I think they haven't fixed every bugs with every computers yet.

Thanks to https://askubuntu.com/users/36140/robert-sederholm!

Thanks also to jeydee, who kindly answered me.


I had some ACPI related issues on Lenovo IdeaPad 330 running Ubuntu 18.04.1. Passing acpi=off fixed some of them (WLAN card detection, freezes on logout, and most random freezes), but it broke some other things instead: Ubuntu froze on reboots/shutdowns, touchpad didn't work, battery not detected, and also after installing nvidia CUDA drivers nvidia-msi was failing to communicate with /dev/nvidia0 reporting ACPI related errors in dmesg. What worked for me was replacing acpi=off kernel boot option with acpi_osi=Linux (and I also noticed nomodeset the OP mentioned broke some things too). You can read about acpi_osi=Linux option in this answer.
