Check SSd health in linux

Step 1: Install the smartmontools package with the command “sudo apt install smartmontools”.

 sudo apt install smartmontools

Step 2: Run the command “sudo smartctl -t short -a /dev/sdX” (in place of sdX, use the name of your SSD). This will run a short test that takes approximately 2 minutes.

sudo smartctl -t short -a /dev/sdX 

Step 3: When the test is completed, run the command “sudo smartctl -a /dev/sdX” to display the results.

sudo smartctl -a /dev/sdX

Constant noise / beep when mu sound play on headphones / speakers

When using ubuntu 20.04 i notice that when not playing any sound over external speakers i have constant long beep.

i check pulseaudio logs and i notice when the pulseaudio going in to suspend this noise / beep start.

systemctl --user stop pulseaudio.socket
systemctl --user stop pulseaudio.service
pulseaudio -v

solution is to comment the line 

load-module module-suspend-on-idle

in file

/etc/pulse/default.pa

then restart pulse audio

systemctl --user restart pulseaudio.service

Nvidia CUDA and Steam in Ubuntu 20.04

When installing the CUDA developement package then when you like to run the Steam to play some games most likely you will see steam updating itself and the windows close.

When you will run steam from the terminal you will notice this errors

SteamUpdateUI: An X Error occurred

If you need CUDA and STEAM there is solution the issue if with the OpenGL 32bit library

  1. Download CUDA installation file (file is 4Gb so look for the space)
wget wget https://developer.download.nvidia.com/compute/cuda/11.4.2/local_installers/cuda_11.4.2_470.57.02_linux.run
  1. Add executable attribute to downloaded file
chmod a+x cuda_11.4.2_470.57.02_linux.run
  1. Remove all the nvidia from the system
sudo apt-get purge nvidia*
  1. Then we need to install base mesa drivers with the OpenGL
sudo apt-get install --reinstall xserver-xorg-video-intel libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
  1. Now we need to reconfigure the X server
sudo dpkg-reconfigure xserver-xorg
  1. Now to reboot system and when starting of Ubuntu please select “Advanced options for Ubuntu”
ubuntu grub
  1. with next window please choose latest version of kernel with additional label “(recovery mode)”
  1. when the dialog will show then please choose “Drop to root shell prompt”
  1. now we need to run the CUDA installation by executing downloaded files (yes we need to installed when the X server is not in use otherwise the drivers will be not installed)
./cuda_11.4.2_470.57.02_linux.run

first screen after long waiting is licence and we need to type “accept”

  1. Next screen is what elements will be installed we not changing on selections and move to “Options”
  1. When in option we need to choose “Driver Options”
  1. On this screen we need to select “Do not install any of the OpenGL-related driver files”
  1. After the selection we need to go back to the install screen by selecting “Done”
  1. Once we in the first screen please select “Install” and wait for it to finish.
  1. When the CUDA install process will finish then please type “reboot” in terminal. after reboot finish you should be able to open steam and play games
