[Motorola Atrix 2] oliverthered:
usus transformer infinity t700t

When I read the article it seemed like a custom kernel was installed. Stock kernels may not be compiled with VT support, anyhow

my t700t is as follows

ls -l /dev/tty*

ot@android-fe30b4a8071b23ff:/dev# ls tty*

tty tty0 tty1 tty2 ttyFIQ0 ttyHS1 ttyHS2 ttyHS3 ttyHS4 ttyS0 ttyS1 ttyS2 ttyS3

root@android-fe30b4a8071b23ff:/dev# ls -l tty*

I added the -> links myself...

when I run x (using Xorg to start it) it tells me:

so the console is using ttys0 at 155baud

so I'm going to have a look at VT support, though I probably need a custom kernel to get it up and running.

here's a list of devices on my t770t as reported by sysfs

You can start xorg as follows

Xorg vt##

replacing ## with the number of the vt e.g.

Xorg vt0

This gives me a mix of three sperate errors, a file not found if the vt# isn't in /dev/vtt#, and io error if i symlink to a ttys and ad error saying the device doesn't exist if i symink tty0 to tty
