Trying to open directly...Device open failed

Ubuntu 13.10 & [amd-catalyst-13.4-linux-x86.x86_64.zip][1] http://support.amd.com/en-us/download/desktop?os=Linux%20x86_64

xorg.conf created by

   # aticonfig --initial -f --adapter=all

Thereafter, i modify it with next /etc/X11/xorg.conf

   Section "Module"
   Disable "dri"
   Disable "dri2"
   EndSection

Start phoenix:

   $ ./phoenix.py bitcoin_deepbit_gpu.cfg
   [10/28/2013 02:30:08] Welcome to Phoenix v2.0.0
   [0 Khash/s] [0 Accepted] [0 Rejected] [DISCONNECTED]X server found. dri2 connection failed!
   Trying to open directly...Device open failed

Start cgminer:

   $ ./cgminer --scrypt -T --url stratum+tcp://stratum.coinex.pw:9000 --user user --pass pass --no-submit-stale --queue 4 --scan-time 1
   [2013-10-28 02:41:21] Started cgminer 3.6.6
   X server found. dri2 connection failed!
   Trying to open directly...Device open failed

I have partially solve this trouble with `--gpu-platform 0`:

   $ ./cgminer --scrypt --gpu-platform 0 -T --url stratum+tcp://stratum.coinex.pw:9000 --user user --pass pass --no-submit-stale --queue 4 --scan-time 1
   [2013-10-28 02:43:12] Started cgminer 3.6.6

   ....

But what is it? And how to specify platform for phoenix miner?

There is only one option in phoenix config:

   name = GPU 0 #The name to display the device as (default is device ID if not specified)

It doesn't help.
