I know that sometimes I have the option to change my video display driver, and I can access this functionality by using System→Administration→Additional Drivers. But what's the simple way to see what driver my Ubuntu 10.04 or 10.10 system is using currently?
UPDATE -- I found a command I didn't know about in How to determine version and origin of proprietary drivers.
Martin Owens gives this example output:
kmod:nvidia_current - nvidia_current (Proprietary, Enabled, Not in use) pkg:sl-modem-daemon - Software modem (Proprietary, Disabled, Not in use)
kmod stands for kernel module, pkg is obviously an apt package. According to the code, jockey installs the latest candidate package and ignores any detectable kernel modules or blacklisted modules.
The output is more descriptive than that from
lshw by itself, but I think it is limited to giving information about drivers that were installed with jockey in the first place. Jockey, launched as jockey-gtk, is (I believe) the same application that runs when you select System→Administration→Additional Drivers .
