the following solution works for my old dell Chromebook
echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf
A power off and then power on might be needed.
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:
Muscle Memory Makeover
Docker just streamlined Docker Compose by integrating it as a plugin. Great news, but it means us old hats need to retrain our fingers. Here's a quick fix for your .bashrc to keep things smooth:
alias docker-compose='docker compose'
As a programmer and Linux admin, I juggle multiple MySQL servers with different group suffixes. Typing --defaults-group-suffix every time was a drag. This handy bash function saves the day:
m() {
if [ $# -eq 0 ]; then
# If no arguments provided, run mysql directly
mysql
elif [[ "$1" == -* ]]; then
# If first argument starts with -, pass all arguments directly to mysql
mysql "$@"
else
# Otherwise, treat first argument as suffix
local suffix=$1
shift
mysql --defaults-group-suffix=$suffix "$@"
fi
}
Now, connecting to a database is as easy as:
m specific-suffix
This keeps your workflow concise and saves you precious keystrokes.
Put them into you .bashrc or .zshrc now and let our life easier!
