I'm running FC5 on a Dell Optiplex GX180. Window dragging produces a kind of trippy trails.

I thought I should try installing a new video driver. So I downloaded a rpm from Intel's archives and installed it.

Now it seems that I have two rpms and maybe two modules (drivers) installed.
How do I know which module/driver is active?
If only one is active, should I remove the inactive's rpm?
And if so, how do I know which rpm corresponds to the inactive module/driver?

Here is some background output.

thanks in advance for any help you can provide. Even a pointer to a tutorial about how rpms, modules, drivers work would be appreciated.

Try 'lsmod' there is a column called Used that will show you now many devices are using it and then another column called Used By that will show the module.

Your output shows it: i2c_algo_bit 8393 1 i2c_i810

Also, you can see the man page for RPM...there is a --whatprovides option that shows details about which RPM provided which files.
