Startx -> "AddScreen/ScreenInit failed"

[menos16]

Hello people, and thanks for your help and your time...

I'm trying to start a desktop environment on a mele a1000 (or 2000, not sure) but i'm having problems and I don't have idea about where to begin because I don't know where is the problem... I explain the situation a little:

Over ssh connection, with a normal user, first I check that the following packages are installed

pacman -Q |grep video

$this->bbcode_second_pass_code('', 'videoproto 2.3.2-1
xf86-video-fbdev 0.4.4-4
xf86-video-fbturbo-git 196.046a771-4')

and the property modules are loaded lsmod

$this->bbcode_second_pass_code('', 'Module Size Used by
8192cu 432917 0
btrfs 633984 0
nfsd 213873 13
mali_drm 2220 0
drm 157553 1 mali_drm
mali 87903 0
ump 27260 1 mali
lcd 3308 0
hdmi 21703 0
disp 293113 2 lcd,hdmi
cfbfillrect 2636 1 disp
cfbimgblt 1610 1 disp
cfbcopyarea 2326 1 disp')

second, chet the xorg.conf doesn't exist, only the cat /etc/X11/xorg.conf.d/99-fbturbo.conf
$this->bbcode_second_pass_code('', 'Section "Device"
Identifier "Allwinner"
Driver "fbturbo"
Option "AccelMethod" "G2D"
Option "DRI2" "true"
EndSection')

I think that it should be enough to run the fbturbo driver with the graphics card and use the HDMI output, (Although I'm not sure). So I run the commands...
export DISPLAY=:0.0 (to init the X server on local hdmi from my ssh session) and startx but I didn't success. The Xorg server try to start, but only i get the message AddScreen/ScreenInit failed for driver 0

And the only thing that I can do is read the log and copy here....

How can I find the problem? What I'm doing wrong?

This is the real problem.

Which kernel are you using?

[menos16]

uname -r
$this->bbcode_second_pass_code('', '3.4.103-3-ARCH')

i'm not sure but I think that is not an old version

This weekend I migrate the kernel to the standard branch "linux-armv7 3.19.3-1" and the problem was solved... now I can initialize the X server, although with poor performance.... What is the difference between armv7 and sun4i kernell about the graphics drivers or hardware acceleration? ( I will search in the forum )
