With the ‘root’ user use ‘lsmod’ and ‘modinfo’ (This example is from a 13.2 system with an AMD OLAND card):
# lsmod | grep -i 'radeon'

You can also (as a “normal” user) check the contents of “/var/log/Xorg.0.log” for information about what the X11 Server is doing with your graphics driver:
25.103] (II) RADEON(0): Creating default Display subsection in Screen section
"Default Screen Section" for depth/fbbpp 24/32
25.103] (==) RADEON(0): Depth 24, (--) framebuffer bpp 32
25.103] (II) RADEON(0): Pixel depth = 24 bits stored in 4 bytes (32 bpp pixmaps)
25.103] (==) RADEON(0): Default visual is TrueColor
25.103] (==) RADEON(0): RGB weight 888
25.103] (II) RADEON(0): Using 8 bits per RGB (8 bit DAC)
25.104] (--) RADEON(0): Chipset: "OLAND" (ChipID = 0x6613)
[HR][/HR]IMHO with the current “radeon” driver there is no need to use AMD’s proprietary “fglrx” driver; with Leap 42.1 the open source AMD drivers also handle Dual-Graphics (APU plus on-board Radeon graphics) perfectly.
