[Angstrom-devel] start X server

[Michael Schnell]

Hi experts,

I found that the OMAP L138 development board by Logic PD I have is 
equipped with a Kernel that includes a graphics driver for the LCD 
interface the chip features.

I do see:

root at da850-omapl138-evm:/dev# ls -l f*
lrwxrwxrwx    1 root     root            3 Jan  1  2000 fb -> fb0
crw-rw----    1 root     video     29,   0 May 15 14:46 fb0
crw-rw-rw-    1 root     root       1,   7 May 15 14:46 full

Unfortunately right now I don't have an LCD panel yet, so I can't see if 
the display shows anything. (When X is installed I'll try to use X11vnc 
to access the FB.)

Now I installed  the packages

xserver-xorg
    and
xserver-kdrive-fbdev

Now I try to start and / or configure the X server.

I get:

I suppose the error

*no screens found*

is due to X not being configured.


But what to do about the

*Missing output drivers ? *


Thanks a lot !
