The most important commands to see what’s going on:

dmesg prints the latest kernel messages

lspci -nn gives you a list of your system’s PCI devices, including vendor & device id
lsusb gives you a list of your system’s PCI devices

lshw -C disk gives you details on all the disk drives in the system
dmidecode gives you a human-readable dmi/smbios table
top gives you the running processes sorted by cpu usage (useful when things get slow)
ethtool -i eth0 gives you the selected network interface’s driver

modinfo <module> gives you info about a kernel module in your system
xev prints info on X events as they happen

df -hl gives you disk usage by file system
cat /proc/cpuinfo gives you details about your cpu
