Linux
The notes here are mainly for Ubuntu/Debian.
SSH
SSH Keys
Generate an ssh-key for every client
ssh-keygen -t ed25519 -a 100 [-C "comment your client name"] [-f output_path]
Some older software such as Solid file explorer require RSA keys in PEM key format
ssh-keygen -t rsa -b 4096 -a 100 -m PEM [-C "comment your client name"] [-f output_path]
You can also convert existing keys to PEM format
ssh-keygen -p -m PEM [-C "comment your client name"] [-f output_path]
Manage ssh keys
# On the client
ssh-copy-id [email protected]
# On the server
vim ~/.ssh/authorized_keys
Notes:
- According to this you should avoid using ECDSA and DSA keys.
Switching between Nvidia and Intel
Reference
Make sure the Nvidia graphics drivers are installed. Then you can select between Nvidia and Intel GPUs using the Nvidia X Server Settings application nvidia-settings. Alternatively, you can use the following commands in the terminal.
To switch to the Nvidia GPU:
sudo prime-select nvidia
To switch back to the Intel GPU:
sudo prime-select intel
prime-select query will print either nvidia or intel to stdout.
