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 libnvidia-encode-550 can pull in conflicting server packages. The newer driver takes over — restart GDM.
