I was talking about these:
# 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
Running Centos. I suppose all these above are for handling different video
cards ?
