I installed SGX drivers following instructions from
http://elinux.org/BeagleBoardUbuntu#Xorg_Drivers, but the X server
still doesn't start.
Looks like omapdrm kernel module was not built by ti-omapdrm.sh:
[ 30.703] (II) LoadModule: "omap"
[ 30.704] (II) Loading /usr/lib/xorg/modules/drivers/omap_drv.so
[ 30.745] (II) Module omap: vendor="X.Org Foundation"
[ 30.745] compiled for 1.12.4, module version = 0.83.0
[ 30.745] Module class: X.Org Video Driver
[ 30.746] ABI class: X.Org Video Driver, version 12.1
[ 30.746] (II) OMAP: Driver for TI OMAP: OMAP3430 with PowerVR SGX530,
OMAP3630 with PowerVR SGX530, OMAP4430 with PowerVR SGX540,
OMAP4460 with PowerVR SGX540, OMAP5430 with PowerVR SGX544 MP,
OMAP5432 with PowerVR SGX544 MP
[ 30.747] (--) using VT number 2
[ 30.762] (WW) Falling back to old probe method for omap
[ 30.763] drmOpenDevice: node name is /dev/dri/card0
[ 30.803] [drm] failed to load kernel module "omapdrm"
[ 30.804] (EE) No devices detected.
[ 30.804]
Fatal server error:
[ 30.804] no screens found
