Command to see graphics driver used?

hmmmz,

Analyse the output of lsmod, look for suspect modules for example the Nvidia module is just named "nvidia", not sure about ATI.

A second method (possibly better), look in /etc/X11/xorg.conf to see which driver is being used under the "device" section. Mine looks as follows:

Code:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"     *** Your driver ***
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 260"
EndSection

Hope that helps,

Thats the thing, new OS's arent using xorg anymore.

I'm testing debian squeeze atm, and it came pre-installed with the radeon opensource driver.

When I install it properly I wanna make sure it's using it, summit about KMS doing all the shizzle now.

Well, if the driver is correctly loaded and in use then it will show up in the output of lsmod.

If KMS is handling it all for you, im not sure there's another way other than analysing loaded modules. It's probably detailed in dmesg output as well somewhere.

EDIT: assuming it isn't using a kernel built-in graphics driver. dmesg should detail what the KMS uses anyway.
