Problem Description:
After reinstalling the system to Pop!OS22.04, when Zhengmeimei was watching a movie, the picture suddenly freezes and the audio infinitely loops. At first, I thought it was a browser problem. After changing the browser, it happened more frequently.
Solution:
Make the system use integrated graphics instead of nvidia graphics.
You can switch graphics cards like this:
sudo system76-power graphics #Confirm the nvidia graphics card used to confirm the output nvidia
sudo system76-power integrated #Switch to integrated graphics
Follow the prompts to restart the computer and then execute
sudo system76-power graphics #Confirm that the output is integrated and you're done
If it is another ubuntu system, you can consider using prime-select to switch the graphics card
sudo prime-select query # View the current graphics card
sudo prime-select intel # Set Intel graphics card
sudo prime-select nvidia # Set NVIDIA graphics card
This computer has followed me on planes and high-speed trains since 2016, and the screen has already been replaced by a TV, so I can no longer follow me around. There is also a problem with heat dissipation. When I use a discrete graphics card, the temperature is too high, so I have to change to an integrated graphics card. Six years have passed in a flash, thank you for your company, old man!
