[Lazarus] How to get Lazarus on Odroid U3 with Ubuntu 14.04 to work ?

[Corpsman at web.de]

Well i tried with fbset -depth 24

same result see below :

odroid at odroid:~/development/lazarus$ fbset 

mode "1280x1024"
    geometry 1280 1024 1280 3072 24
    timings 0 0 0 0 0 0 0
    accel true
    rgba 8/16,8/8,8/0,0/0
endmode

and in Lazarus when showing the "about" screen

(lazarus:10115): Gdk-WARNING **: Attempt to draw a drawable with depth 24 to a drawable with depth 32

(lazarus:10115): Gdk-WARNING **: Attempt to draw a drawable with depth 24 to a drawable with depth 32

This is the key to the problem.
Using different fpc version, different Lazarus versions, different 
Ubuntu version won't help.

When drawing images on gtk, lazarus has to use the same pixeldepth as 
your X server. gtk won't do any conversion, except for 32 bit. Usually 
drawing 24 bit images on 32 bit X is also OK.
In your case not. The only thing you can do is reducing the pixeldepth 
of your X server.
