Re: Help installing NVIDIA drivers

Hi loki,
I ran this workaround for some 2-3 weeks before discovering the kernel option switch that resolved my issue, during that time the workaround functioned very well and unobtrusively.
Can you explain a bit more what this kernel switch is, and how you have enabled it ?

Thank you !

As mentioned earlier in the thread, the kernel switch/boot parameter that is working for me is...

Code: Select all

acpi_rev_override
You can test it as a one time boot option by pressing 'E' to edit the highlighted grub menu item and add "acpi_rev_override" to the end of kernel line.

Or, to add this option permanently edit the file...

Code: Select all

/etc/default/grub
...Find the line...

Code: Select all

GRUB_CMDLINE_LINUX=""
... and add the option by changing the line to...

Code: Select all

GRUB_CMDLINE_LINUX="acpi_rev_override"
After saving the file changes remember to run update grub...

Code: Select all

# update-grub
The machine's firmware can expose the hardware to the OS differently depending on the ACPI version the OS reports. My machine's firmware expects all Linux OS' to return 5 as the ACPI version, the acpi_rev_override option forces the OS to return 5 as the ACPI version regardless of actual version.

Hi loki,

thank you for your answer.

I confirm that adding

Code: Select all

acpi_rev_override=1
solve the freezing issue in Gnome post login (Ubuntu 17.04) on my Gigabyte Aero 15 laptop.
