Re: [Ltib] Display Device on LPC3250

[Paolo Cremonese]

Hi Stuart,
you are right, I did not startx, but when I did it,

address@hidden /]# export DISPLAY=:0.0
address@hidden /]# startx
Warning: mode not found, using default
error: Invalid argument


Fatal server error:
no screens found
twm:  unable to open display ":0"
killall: Xfbdev: no process killed
address@hidden /]# 

I check also the kernel, and the framebuffer is enabled.
Also, if I do:

ls -la > /dev/fb0

I see some "dirty" on the top line of the LCD so I think the fb0 device
is "connected to the LCD.

to avoid the message:

Warning: mode not found, using default

I have tested (my screen is 240x320)

address@hidden /]# Xfbdev :0 -ac -screen 320x240
error: Invalid argument

Fatal server error:
no screens found
address@hidden /]# 

There isn't "Mode not found", but the screen is still "ghost".

At boot the Linux logo is displayed on the screen, but nothing more.

Regards, Paolo
