Scribbles for my bad memory

Finally, I decided to install xUbuntu on a 256GB SDCard as the 16GB built-in emmc drive on a chromebook (Dell P22T) is too small for a desktop system.

Undoubtly, SDCard is slow and easier to be broken. So I took the following actions to the file system and hope they can help solve both issues:

1. Turning off atime.
2. Disabling the journal feature.

sudo vim /etc/modprobe.d/alsa-base.conf
# add this line at the end of the file & save
options snd_sof sof_debug=1
