Bug description:
Below is a Cut and paste of a recent Ubuntu Forum Page where I posted the
issues
https://ubuntuforums.org/showthread.php?t=2404566
Note that though it says "Solved" it is just workarounds of Bigger ACPI
Issues!
ubuntu 18.10
OK,
This is a new thread, and I will make it HUGE!
Edit Solution/ Work Around for the "2/" Problem
see Post # 4, Thanks PeterSaints
Ubuntu, Please Listen!
Nvidia, HDA WOES in the Title ... HDA stands for High Definition Audio, or
HDMI Audio, or Surround Sound 5.1-7.1 etc. ...
NVHDA stands for Nvidia HDA. Just for anyone who does not know the Jargon!
What does Work ... (and I will post ALL my Notes and Links for others below!)
1/ Everything AFTER STUPIDLY!, I need to install a Kernel PATCH! and
2/ A STUPIDLY Necessary Restart after ANY Hibernation or Suspend!
First my System, and most importantly is it is a NEW Cutting Edge Hp Omen X
Laptop with a Nvidia GTX 1080m GPU, and the latest Linux 3.18 Kernel!
-Computer-
Processor : Intel(R) Core(TM) i7-7820HK CPU @ 2.90GHz
Memory : 16245MB (3330MB used)
Machine Type : Notebook
Operating System : Ubuntu 18.10
-Display-
Resolution : 1920x1080 pixels
OpenGL Renderer : GeForce GTX 1080/PCIe/SSE2
X11 Vendor : The X.Org Foundation
-Audio Devices-
Audio Adapter : HDA-Intel - HDA Intel PCH
Audio Adapter : HDA-Intel - HDA NVidia
-Input Devices-

ST LIS3LV02DL Accelerometer
HDA Intel PCH Mic

HDA Intel PCH Headphone

HDA NVidia HDMI/DP,pcm:3
HDA NVidia HDMI/DP,pcm:7
HDA NVidia HDMI/DP,pcm:8
So the LATEST 2 Problems I am looking for a SOLUTION that would indeed help
THOUSANDS and/or MILLIONS of people Now and/or in the near future!
1/ Why SHOULD I need to apply a PATCH to a YEAR old KNOWN problem!
and MORE IMPORTANTLY!
2/ Why is the fixed Patch System NOT working after a Suspend or Hibernation
(Yes I am reiterating my issue once again!)
After EITHER a Suspend or Hibernation, the HDA Sound is EITHER,
1/ Not VISIBLE AGAIN! ANYWHERE! Trust me, or
2/ Visible but in a Dysfunctional State, ... Showing 3 version of the NVHDA
0,1&2 ...
and NONE of the 3 (three) WORK! to be clear NO SOUND AT ALL! when testing
them.
So I will leave it here, and to show my continued Good Faith and
Obvious Continued Support For Ubuntu, below are ALL my Solutions to
Date!
1st Solution -
Install the patch to get the INVISIBLE and/or Unloaded HDA Visible and/or
Loaded
∘ I can confirm that kernel module, posted by
‣ Maik Freudenberg (https://bugs.freedesktop.org/show_bug.cgi?id=75985#c27),
• Kernel module to toggle audio function
∘ is working fine on my system. Thank you for the fix. The HDMI audio device
now works as it should (now detected).
∘ The steps I did to enable HDMI audio device:
• 1. Download and extract the file nvhda.tar.xz. (from above link)
• 2. Run these commands in Terminal, in the location of the extracted folder
Code:
• $ make
• $ sudo make install
• $ echo nvhda | sudo tee -a /etc/initramfs-tools/modules
• $ echo "options nvhda load_state=1" | sudo tee /etc/modprobe.d/nvhda.conf
• $ sudo update-initramfs -u
‣ 3. Reboot.
## SOLVED ################################################## ###############
2nd Solution
Hibernation/Suspend Working (Not HDA Sound of Course)
Troubleshooting
‣ Prerequisites - does your kernel support suspend-to-disk?
• Kernel supports whatever is listed in /sys/power/state, so:
Code:
cat /sys/power/state
∘ Allowed (to my knowledge) entries there include: mem, standby, freeze,
disk. Explanation:
‣ mem - has several meanings, which one exactly on your system you'll find
out via cat /sys/power/mem_sleep. I have: s2idle [deep]
‣ standby - Power-On Suspend (if supported)
‣ freeze - Suspend To Idle (STI)
‣ disk - Hibernate - Suspend To Disk (STD), This - you want.
∘ mine says : freeze mem disk - PERFECT!
• Then we need to check
Code:
$ cat /sys/power/disk
‣ If (good) shows ...
‣ [platform] shutdown reboot suspend test_resume
• if : (Bad)
• [disabled]
• (not very good)
‣ Enable Hibernate and put it in menu - Easy-Peasy
• Software Prerequisites
Code:
sudo apt install pm-utils cpufrequtils
1. Edit a specific file with this command.
Code:
sudo gedit
/var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla
∘ 2. Scroll down the Text Document and find the below sections:
[Disable hibernate by default in upower]
[Disable hibernate by default in logind]
‣ Change both the values from no to yes in:
ResultActive=no
(change this to yes)
• Save, Exit & Reboot - Done!
• To test if hibernate works in your computer by running command:
Code:
sudo pm-hibernate
• After you computer turns off, switch it back on.
‣ Did your open applications re-open? If so it works, if not then hibernate
does not work. You can check if your Swappiness partition is at least as large
as your available RAM, as it may solve the problem.
3rd Solution
ACPI Woes Bandaid FIX,
ACPI stands for Advance Configuration and Power Interface (Thunderbolt)
If you are getting a ZILLION ACPI Errors of any kind
ex. Error:
ACPI:3400 Unsupported Event
‣ Here is a surprisingly simple solution that solved both problems (fast
startup and normal background)
‣ Try disabling acpi in /etc/default/grub change this variable so it looks
like this:
Code:
sudo gedit /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=strict",
• Just add acpi=off (caused problems), "acpi=strict" Did NOT cause these
problems
• (used for acpi INT34000 Errors but resulted in 800x600 resolution PROBLEM)
• Make sure to
Code:
sudo update-grub2
, after modifying the file and before rebooting
• and reboot
