I would like to try a different video display driver, but I'm not sure which one I'm currently using.

What's the simple way to see what driver my system is using currently?

Run lshw -c video, and look for the line with 'configuration'. The loaded driver is prefixed with 'driver='. Example output:
If you want more information about the loaded driver, run modinfo. Output of modinfo i915:
Note that modinfo works on filenames and aliases, not on module names. The majority of the modules will have the same name for the module name and filename, but there are exceptions. One of them is nvidia.
Another way of using these commands in order to show you the file name of the driver would be:
When loaded, the command lsmod will show the nvidia module as loaded. modinfo nvidia will error out. Why? Because there is no module named 'nvidia', it's just an alias. To resolve the alias you can use modprobe --resolve-alias nvidia. Or to get the whole modinfo in one command:
You could use the following command to see the currently used vga kernel driver:
Example output for an ATI / AMD graphic card:
if the open source Radeon driver is used:
if the proprietary Fglrx driver is used:
Complete Output with lspci -nnk | grep -i vga -A3
Available kernel modules you can see with lspci -nnk | grep -i vga -A3 | grep 'Kernel modules':
Note: This does not work in every case!
For a SiS 65x/M650/740 PCI/AGP VGA Display Adapter, there is no 'Kernel driver in use' line:
and the available sisfb kernel module is not the loaded driver, because lsmod | grep sisfb has no output (sisfb is blacklisted). In this case also sudo lshw -c video | grep Konfiguration does not work. The output is:
without any driver information.
I have tried many ways without succes, but this did work on me (Ubuntu 12.10):
One reason is that I have Nvidia Optimus card and that makes thing harder so I added optirun before the command.
The best information I've seen so far is in nouveau wiki. It can also help with non-nvidia cards:https://nouveau.freedesktop.org/wiki/Optimus/
This is xrandr --listproviders and sudo cat /sys/kernel/debug/vgaswitcheroo/switch. A lot of other useful info how to control power, outputs and offloading, etc.
