Revision as of 18:01, 5 March 2018
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
- Used this version previously
- 387.34 NVIDIA binary
- 390.25 NVIDIA binary
- X.Org Nouveau (open source)
Selected version 390.25 and then reboot, things seem to be working better now.

Disconnecting network (fix)
- Would happen after a period of correct operation
- Disable/enable solves the problem for a period
Info:

- https://askubuntu.com/questions/819376/ethernet-connection-issues-on-ubuntu-16-04
It is 'well known' that driver r8169 driver 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
