Ubuntu troubleshooting
From WickyWiki
After upgrading my system usually I run into some problems.
System configuration
- Ubuntu 16.04
- AMD Ryzen 5 CPU
- Motherboard MSI B350 PC Mate
- Videocard Nvidia MSI GTX-1060 6GB
Game-audio gritty distortion, crackling (fix)
- happens with older games, for example with World of Goo
- pulseaudio
Info:
Edit "/etc/pulse/default.pa", find "load-module module-udev-detect" and add "tsched=0":
sudo nano /etc/pulse/default.pa
load-module module-udev-detect tsched=0
Restart the PulseAudio server:
pulseaudio -k pulseaudio --start
Regular periods of freeze, getting worse
- system interface slows quickly, mouse stutters, until it freezes completely
- switch to terminal (Ctrl+Alt+F1) and back seems to fix it for a while but it will come back
- not switching results in a fatal freeze
- does not seem to happen when left alone
- freeze on play of certain videos

Reinstall from Nvidia repository (possible fix)
Nvidia settings:
sudo nvidia-settings
Removed all Nvidia drivers:
sudo apt-get remove --purge nvidia-*
Added Nvidia repository, now more options under additional drivers
sudo apt-add-repository ppa:graphics-drivers/ppa sudo apt-get update
Options:
- 384.111 NVIDIA binary
- 387.34 NVIDIA binary
- 390.25 NVIDIA binary
- X.Org Nouveau (open source)
Version 384.111 was selected, selected version 390.25 instead. After the reboot things seem to be working better.

It is 'well known' that the newer driver r8169 is flawed.
Check if this driver is used
sudo lshw -C network | grep driver
Install r8168-dkms driver
sudo apt-get update sudo apt-get install r8168-dkms
Reboot
