I'm still new to Ubuntu. Would appreciate any help with this, thank you.

Here are my specs. I'm using a laptop Clevo P7xxTM1 with

  • i7 8700
  • 32GB RAM
  • gtx 1070 GPU

I dual boot Windows 10 and Ubuntu 16.04 and 2 other drives for storage, one for each OS. Recently I upgraded my hardware from a samsung 850evo to WD Black M.2 NVMe for my Linux OS expecting performance gains. Since then I have had nothing but problems. The major concern for me is the performance. I was expecting near instant boot, shut down, and software loading. What I got is almost the opposite. Sometimes when I shutdown the system takes a good 5 min to reboot/shut down. Boot time is much faster, but sometimes it hangs and system freezes at the login screen and right after logging in. Some programs can take a while to load. Sometimes just browsing in file explorer will cause random pauses or freezes. Not sure if this is related, but when I play .mkv files and try to browse through the video it can cause the entire system to lock up.

Here's what my screen looks like after I hit ctrl+alt+F1

ctrl+alt+F1

Is this a known problem for Linux on nvme drives or was there something I had to do extra besides install it?

edit: Here's a picture of a recent attempt of trying to shutdown and the message I get on screen.

  • This probably won't help but for my Samsung Pro 960 NVMe SSD I had to set this grub parameter for suspend/resume to work properly: acpiphp.disable=1. It has something to do with disabling power savings for the SSD. – WinEunuuchs2Unix Mar 24 '18 at 01:38
  • I'm new to linux and I don't know exactly how to set these parameters. Would you link a tutorial for me? – Pachuca Mar 24 '18 at 14:07

This looks similar to the issue reported here (EXT4-fs error after Ubuntu 17.04 upgrade), which appears to have been resolved by partially or fully disabling the APST (Autonomous Power Saving Transition) features on the drive. Try adding nvme_core.default_ps_max_latency_us=5500 to your kernel command-line parameters and see if that helps.

  • Seems to have worked, but one big problem. My windows 10 doesn't show up in the GRUB menu to boot from. I don't even see it as an option in the BIOS. – Pachuca Mar 24 '18 at 13:46
  • When Windows 10 disappears from grub menu, it's happened to me at least twice I use boot-repair and select the recommended repair option. – WinEunuuchs2Unix Mar 24 '18 at 22:58
  • never mind found my answer in another thread. Just had to type in terminal sudo os-prober and sudo update-grub now I see windows as a boot option, thank you! – Pachuca Mar 25 '18 at 01:12
