# Detect devices that need additional drivers
sudo ubuntu-drivers devices
 
# Automatically install recommended drivers
sudo ubuntu-drivers autoinstall
 
# Install a specific driver (use the version recommended by `ubuntu-drivers devices`, e.g. 580/590)
sudo ubuntu-drivers install nvidia-driver-580

# View DKMS-managed modules
dkms status
 
# Manually rebuild modules
sudo dkms autoinstall
 
# If a module fails to build
sudo dkms remove MODULE_NAME/VERSION --all
sudo dkms install MODULE_NAME/VERSION

# Check DKMS status
dkms status
 
# Ensure build tools are installed
sudo apt install build-essential dkms linux-headers-$(uname -r)
 
# Rebuild all DKMS modules
sudo dkms autoinstall

# Check blacklists
grep -r "blacklist" /etc/modprobe.d/
 
# Temporarily load a blacklisted module

# Comment out the relevant line, then regenerate the initramfs (Ubuntu 26.04 uses Dracut by default):
sudo dracut -f
# On legacy initramfs-tools systems use instead: sudo update-initramfs -u

# Check for firmware missing warnings
sudo dmesg | grep -i firmware
 
# Install the full firmware package (all of Ubuntu's binary firmware lives in linux-firmware)
sudo apt install linux-firmware

sudo apt install linux-generic-hwe-26.04
