(EE) ioctl EVIOCGNAME failed: Inappropriate ioctl for device

Unable to query/initialize EVTouch hardware.

[dix] couldn’t enable device 13

If you run into problems getting Xorg to start up and see an error similar to the one above it may have something to do with evtouch being installed. In

/usr/lib/X11/xorg.conf.d/

there are a few different configuration files. If there is a evtouch one, probably named

10-evtouch.conf

rename it or remove it. For example, put it in a bak/ directory in that same location. This was preventing Xorg from working properly even with the evdev driver setting in Xorg.conf. It seemed the Xorg somewhere used this

10-evtouch.conf

configuration file, which was missing a MatchDevicePath directive which threw the

(EE) ioctl EVIOCGNAME failed: Inappropriate ioctl for device

error. This blog was helpful in troubleshooting: http://www.viitalat.net/index.php/htpc/2010/07/15/lg-1730sf-on-ubuntu-10-04

No Network Connection

Check what the network interfaces are:

ifconfig -a

To request a DHCP lease for an interface, do

sudo dhclient $interface

(where $interface is whatever network interface you want the DHCP lease on)
