X11 video drivers - shared libraries ?

Hello,

I just wanted to check X11 video driver.
But looks like all the drivers are *.so files:

Code:

 ls /usr/lib64/xorg/modules/drivers

ast_drv.so      ch7xxx.so        i810_drv.so  r128_drv.so      savage_drv.so        tfp410.so      voodoo_drv.so

ati_drv.so      cirrus_alpine.so  intel_drv.so  r500_drv.so      sil164.so            trident_drv.so

atimisc_drv.so  cirrus_drv.so    ivch.so      radeon_drv.so    siliconmotion_drv.so  vesa_drv.so

ati_r500_drv.so  cirrus_laguna.so  mga_drv.so    radeon_tp_drv.so  sis_drv.so            vga_drv.so

ati_tp_drv.so    dummy_drv.so      nv_drv.so    s3_drv.so        sisusb_drv.so        via_drv.so

ch7017.so        fbdev_drv.so      qxl_drv.so    s3virge_drv.so    tdfx_drv.so          vmware_drv.so

I used to know that all linux drivers are kernel modules (*.ko files) and I can check if they are loaded with lsmod.
Could someone explain me:
Are these *.so files X11 drivers ?
Are they kernel modules ?
Can I use lsmod to check if they are loaded ?

thanks

Generally kernel modules (you can say drivers) are located in

Code:

/lib/modules/$(uname -r)/

modules are .ko file (.o in older kernel) and you can use lsmod command to see loaded modules.
modinfo command provide module information.

Code:

$ sudo lsmod | grep pcnet32



$sudo modinfo pcnet32



filename:      /lib/modules/2.6.26-2-686/kernel/drivers/net/pcnet32.ko

I know enough about kernel modules.

My question was why X11 drivers are not kernel modules.
And what these drivers are then ?

Look at this Directory

Code:

/lib/modules/2.6.26-2-686/kernel/drivers/video/

In my debian system ( VMWARE )

Code:

$ sudo lsmod | grep intel

intel_agp              22524  1

agpgart                28808  1 intel_agp



$ sudo modinfo intel_agp | head -2

filename:      /lib/modules/2.6.26-2-686/kernel/drivers/char/agp/intel-agp.ko
