HP laptop, Ubuntu 18.10, and runaway kacpid process !!PLS HELP!

So guys, I’ve been having trouble last couple of days trying to fix kworker/0:4+kacpid. All I know is that its consuming 90-100% of my CPU when no programs are running. So ill just list things I have tried and failed with so if you have any more suggestions or if you had same problems pls comment I’d rly like to fix this.

What have I tried and relevant informations:

  1. Laptop is HP ProBook 450 G3 with i3-6100, AMD R7 M340, 8GB ram, 2 SSD – 1. with Ubuntu 18.10, 2. with Windows 10
  2. I have updated BIOS and all the drivers HP offers on their site for my laptop, but only thing is that drivers are for Windows, they have no drivers for linux as you can see for yourself. https://support.hp.com/us-en/drivers/selfservice/hp-probook-450-g3-notebook-pc/7834555
  3. I have tried to download off official AMD site latest drivers for my R7 M340 but latest is for ubuntu 14.04, ubuntu update center offers no additional drivers and I get message my machine is up to date.
  4. I have tried setting in grub acpi=strict and pnpacpi=off non have worked.
  5. I have tried running live machines off usb to check if kacpid is still consuming 90% of CPU and IT IS on: Ubuntu 19.04, Ubuntu 18.10, Ubuntu 14.04, Fedora 29… yes all of them were 64 bit, so you can exclude GNOME and GNOME extensions as a problem…
  6. I have started a thread few days ago and if you would like to check out comments of people trying to help me resolve my problem here is the link: Ubuntu 18.10 CPU1 always around 100% despite no programs are running

I’d rly like to resolve this and if you even have suggestion what should i try pls leave a comment, I’m new to whole linux scene and I would rly like to stay. 🙂

Ubuntu 18.10 Asus GL504GV fn keys (screen and kb backlight) not working

My main problem is that rgb keyboard lighting all day on, as there is no way to turn it off. I tried to change the settings on windows, but keyboard tunrs on after rebooting.

I tryed almost everything I found over the Internet, but no luck. Some posts suggest to manually set bright values on /sys/class/leds/asus::kbd_backlight/* but in my case this directory does not exists.

$   ls /sys/class/leds/ asus::lightbar           input11::scrolllock  input8::kana asus-wireless::airplane  input4::capslock     input8::numlock input11::capslock        input4::numlock      input8::scrolllock input11::compose         input4::scrolllock   phy0-led input11::kana            input8::capslock input11::numlock         input8::compose 

Also having some trouble with modprobe

$   sudo modprobe asus-laptop  modprobe: ERROR: could not insert 'asus_laptop': No such device 

For the screen brightness I guess i can work arround /sys/class/backlight/intel_backlight values

Thanks in advance

Ubuntu 18.10 doesn’t have the GTK inspector and I just want a terminal border

gsettings set org.gtk.Settings.Debug enable-inspector-keybinding true 

doesn’t work, as I don’t have the Debug directory under Settings…

I have managed to use the variable tho, and got this https://cdn.discordapp.com/attachments/567363514612711424/567947253008957441/unknown.png

( Not pasting it since I thought it would be relevant to keep it as an image )

It’s not reading the color for some reason, not to mention this works

https://cdn.discordapp.com/attachments/567363514612711424/567941903018885120/unknown.png

So the selectors are ok, but how in the hell would I go about to get the terminal a border?

Intermittent nVidia driver loading – ERROR: Unable to load info from any available system (Ubuntu 18.10)

Experimenting with bleeding edge drivers via graphics-drivers PPA

Dual-GPU laptop, Ubuntu Budgie w/ nvidia-driver-418 freezes the screen after about 15 seconds of logging, except for the mouse, so I tried nvidia-410 and 415 and it only sometimes loads.

nvidia-settings throws the error ERROR: Unable to load info from any available system

but loads with partial screen enter image description here

Pop!_OS 18.10 – Screen doesn’t turn back on after Power Save Blank Screen

I have my timer set on 5 minutes. When it turns off the display, (my) user input does not wake it.

The strange thing is my monitor will turn on, but the screen will stay black. A friend of mine used AnyDesk to remotely control it, and we confirmed my input is working. I entered my password and logged in while the screen was black and while he was still connected via AnyDesk and he was still able to move my mouse around and capture this log file.

My specs:

AMD® Ryzen 7 1700x eight-core processor × 16 Radeon RX Vega 64 (VEGA10, DRM 3.26.0, 4.18.0-17-generic, LLVM 7.0.0) Motherboard is a MSI x370 Pro Carbon Gaming 

Also, I wasn’t able to install the official Vega 64 drivers. After a reboot, they black screen me and I have to use TimeShift to get back and running.

Here is the log:

Headphones not working in 18.10

I am using an old Sony Vaio. Everything works fine, including sound from the laptop speakers. However, every time I try to use the headphones from the side jack, they do not work

I have tried: $ sudo gedit /etc/modprobe.d/alsa-base.conf but the file does not show me the name of the sound card as it was suggested in other posts.

I have tried changing settings in Alsamixer, to no avail.

I have also tried changing the headphone configurations using: $ cd /usr/share/pulseaudio/alsa-mixer/paths/ $ sudo cp analog-output-headphones.conf analog-output-headphones.bak $ sudo nano analog-output-headphones.conf

In the latter case, I tried to change a set of ‘switch’ from ‘off’ to ‘on’, and ‘volume’ from ‘merge’ to ‘ignore’, as suggested in other posts. I tried to change these in different elements, e.g. [Element Speaker], but nothing I tried has worked so far.

Pulseaudio seems to recognise the headphones when I put the jack on, but no sound comes from them.

Can you please help me solve this issue? Thanks in advance

Send mail notification Ubuntu 18.10

I’ve set up unattended upgrades, and wish to receive an email on every update run to make sure it’s running. Previously I used ssmtp to do this but apt install ssmtp return:

The following packages have unmet dependencies:                                         ssmtp :     Depends: libgnutls-openssl27 (>= 3.0-0) but it is not going to be installed   E: Unable to correct problems, you have held broken packages. 

How do I configure my server to use an external smtp server that uses login and ssl/tls security?

(I want to send from “noreply@example.com” on mail.example.com:465.)

Ubuntu 18.10 slow boot on SSD with dual boot Windows 10

I have a Lenovo y50, core i7, 16gb RAM with a 1TB Samsung Evo 6 SSD setup with the following structure –

Ubuntu 18.10 – full disk encryption on 750gb. (No swap partition for the ubuntu)

Windows 10 – no encryption on 230gb.

Thing is, the Windows 10 boots up in 3s while the Ubuntu 18.10 boots up in approximately 2 minutes.

Here are some commands i ran to identify whats wrong,

Output of systemd-analyze – https://pastebin.com/AfAZ1gKN

Output of systemd-analyze blame – https://pastebin.com/CSkp5ViH

Output of sytemd-analyze critical-chain – https://pastebin.com/tUCWuzcA

Any help to reduce the boot times would be greatly appreciated. Thank you.

18.10 Dell Latitude 7567 dual monitor was working but not now

After a couple of days and 3 reinstalls (including switching from Debian to Ubuntu) I has dual monitor working (laptop and and external) but my joy was short lived. The next day I booted up I am back to my external monitor not working. I don’t think I changed anything. The last thing I did was get grub to save my last option (changing /etc/default/grub) but am tested after that.

When I go to the nvida control panel ‘X Server Display Configuration’ and go to the second display I get ‘PRIME Displays cannot be controlled by nvidia-settings and must be configured by an external RandR capable tool. The display is shown in the layout window for information purposes only’.

Did a bit of googling but could not find anything that seemed relevant for 18.10.

My drivers are:
