I don't know if there is a command to indicate what driver is being used by the X11 system. I also don't have a functional debian system at the moment but running
sudo grep driver /var/log/Xorg.0.log on my Fedora 22 laptop gives: [ 40.931] X.Org XInput driver : 21.1 [ 44.288] (==) Matched intel as autoconfigured driver 0 [ 44.288] (==) Matched intel as autoconfigured driver 1 [ 44.288] (==) Matched modesetting as autoconfigured driver 2 [ 44.288] (==) Matched fbdev as autoconfigured driver 3 [ 44.288] (==) Matched vesa as autoconfigured driver 4 [ 44.288] (==) Assigned the driver to the xf86ConfigLayout [ 44.288] (II) Loading /usr/lib64/xorg/modules/drivers/intel_drv.so [ 44.642] (II) Loading /usr/lib64/xorg/modules/drivers/modesetting_drv.so [ 53.891] (II) Loading /usr/lib64/xorg/modules/drivers/fbdev_drv.so [ 54.058] (II) Loading /usr/lib64/xorg/modules/drivers/vesa_drv.so [ 54.084] (II) FBDEV: driver for framebuffer: fbdev [ 54.084] (II) VESA: driver for VESA chipsets: vesa [ 54.096] (II) intel(0): Using Kernel Mode Setting driver: i915, version 1.6.0 20151010 [ 54.166] (II) intel(0): [XvMC] xvmc_vld driver initialized. [ 54.166] (II) intel(0): [DRI2] DRI driver: i965 [ 54.166] (II) intel(0): [DRI2] VDPAU driver: va_gl So it looks like I'm using (on my laptop, not the G5) either the intel driver, the fbdev driver, or the vesa driver. sudo grep -i fbdev /var/log/Xorg.0.log [ 44.288] (==) Matched fbdev as autoconfigured driver 3 [ 53.891] (II) LoadModule: "fbdev" [ 53.891] (II) Loading /usr/lib64/xorg/modules/drivers/fbdev_drv.so [ 54.058] (II) Module fbdev: vendor="X.Org Foundation" [ 54.084] (II) FBDEV: driver for framebuffer: fbdev [ 54.099] (WW) Falling back to old probe method for fbdev [ 54.099] (II) Loading sub module "fbdevhw" [ 54.099] (II) LoadModule: "fbdevhw" [ 54.099] (II) Loading /usr/lib64/xorg/modules/libfbdevhw.so [ 54.110] (II) Module fbdevhw: vendor="X.Org Foundation" [ 54.119] (II) UnloadModule: "fbdev" [ 54.119] (II) Unloading fbdev [ 54.119] (II) UnloadSubModule: "fbdevhw" [ 54.119] (II) Unloading fbdevhw so it's not using the fbdev driver sudo grep -i vesa /var/log/Xorg.0.log [ 44.288] (==) Matched vesa as autoconfigured driver 4 [ 54.058] (II) LoadModule: "vesa" [ 54.058] (II) Loading /usr/lib64/xorg/modules/drivers/vesa_drv.so [ 54.084] (II) Module vesa: vendor="X.Org Foundation" [ 54.084] (II) VESA: driver for VESA chipsets: vesa [ 54.110] (WW) Falling back to old probe method for vesa [ 54.119] (II) UnloadModule: "vesa" [ 54.119] (II) Unloading vesa so it's not using the vesa driver Must be using the intel driver (which makes sense since this is an i7 laptop).
