tmux Sessions¶

Session	Purpose
`isaac-setup`	Setup and installation
`isaac`	Running Isaac Sim
`work`	General commands

tmux new -s isaac-setup    # Create
tmux attach -t isaac-setup # Attach
tmux ls                    # List

Troubleshooting¶

NVIDIA driver issues after update¶

# Check what's installed
dpkg -l | grep nvidia | grep -E '^ii'

# Check DKMS status
dkms status

# Restart GDM to reload driver
sudo systemctl restart gdm

# Verify driver works
nvidia-smi

Installing an older libnvidia-encode package (e.g., -550) can pull in conflicting server packages. The newer driver takes over -- restart GDM.
