Boot Issues on Ubuntu 18.04 (Asus Vivobook S14)

I have been having issues when booting and rebooting on my laptop (Asus Vivobook S14, i7 processor, GeForce MX150 graphics card). I have a dual-boot setup with Ubuntu 18.04 and Windows 10. Oftentimes when I reboot, it doesn’t get to the login screen, though it does get past Grub. At this point, I have to physically power off the laptop and try again, and it seems to boot to login roughly 1/3 of the time. Once I get to the login screen, there are no issues.

‘sudo reboot’ always triggers this issue, as does restarting from the menu in the top right. Also, if I try to go to recovery mode, it can get stuck at ‘Loading initial ramdisk…’ at which point I have to physically restart the computer. I’ve also been trying to get scripts to run on startup and have tried cron, adding to ./xsessionrc, and adding to Startup Applications, and none of these work, and I’m not sure if the problems are related.

I’ve been having these issues since I installed Ubuntu a few months ago, and hoped it would go away through updates. Any help is appreciated.

How to turn off Graphic card in Ubuntu 18.04 server

I recently got a HP Z420 8-core desktop PC with 32GB RAM, and set it up as a headless Ubuntu 18.04 server. The mainboard has no on-board graphic card. So I’m forced to install a video card, lspci | grep VGA gives: 05:00.0 VGA compatible controller: NVIDIA Corporation GT218 [NVS 300] (rev a2).

I wonder if it possible to turn off the graphic card completely to avoid the constant heat generated by the graphic board, which is not used.

I tried blacklist nvidia and nouveau. But that doesn’t seem to change anything.

Can anyone please share some insight as how to disable the graphic card?

18.04 – Screen tearing with NVIDIA GTX 970

I seem to be having problems with screen tearing in Ubuntu 18.04, which got confirmed by running this test:

I searched around in Google for a while, but all I found were recommendations to change the file /etc/modprobe.d/nvidia-drm-nomodeset.conf and add

options nvidia-drm modeset=1 

But that did nothing.

These are the drivers that I am using:

UnicodeDecodeError error when starting Software Properties GTK Ubuntu 18.04

There is an issue when I try to launch software-properties-gtk on Ubuntu 18.04. Nothing happens when launching via desktop icon, and via terminal this error comes out:

root:~# software-properties-gtk  Traceback (most recent call last):   File "/usr/bin/software-properties-gtk", line 100, in <module>     app = SoftwarePropertiesGtk(datadir=options.data_dir, options=options, file=file)   File "/usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 189, in __init__     self.show_keys()   File "/usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 886, in show_keys     for key in self.apt_key.list():   File "/usr/lib/python3/dist-packages/softwareproperties/AptAuth.py", line 64, in list     for line in p:   File "/usr/lib/python3.6/codecs.py", line 321, in decode     (result, consumed) = self._buffer_decode(data, self.errors, final) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 6808: invalid continuation byte 

It looks like a file contains a non-UTF8 character, but I am unable to know which one. /etc/apt/sources.list.d directory is empty, and /etc/apt/sources.list contains:

Missing Icons After Playing around in Ubuntu 18.04 LTS

I have been playing around themes and icons in Ubuntu for a while now. Due to low disk space, I decided to remove unwanted themes and Icons. /usr/share/icons$ sudo rm -rf Adwaita etc I use Numix Circle for Icons, Canta Dark theme and Flat-Remix-Darkest-fullPanel for Shell theme. I control all these using Gnome Tweaks tool.

After all this everything is fine, except ubuntu logo is missing in Settings>About. Also many of the default icons are missing when I use any other icon theme provided by Ubuntu, even after reinstalling the uninstalled ones. What I am missing here? I did not reinstall some themes. Do you think themes would have these icons?
