directfb enabling

[Oguz Yarimtepe]

Hi,

I am trying to run some of the applications by using DirectFB. After
googling a bit i enabled the framebuffer property at my Ubuntu Hardy.
Here is the fbset and dfblayer outputs

# fbset -i

mode "1280x1024-77"
# D: 131.096 MHz, H: 80.328 kHz, V: 76.649 Hz
geometry 1280 1024 1280 1024 32
timings 7628 160 32 16 4 160 4
rgba 8/16,8/8,8/0,8/24
endmode

Frame buffer device information:
Name : VESA VGA
Address : 0xc0000000
Size : 8060928
Type : PACKED PIXELS
Visual : TRUECOLOR
XPanStep : 0
YPanStep : 0
YWrapStep : 0
LineLength : 5120

I can set the frame layer by using dfblayer -m also. To test the
directfb issue, i change to another virtual konsole and stopped the
gdm so that no X will be running.

I ran links2 first.
# links2 -driver directfb

But when i ran the links2 with -driver fb, it worked. I also tried to
run rage application which is supplied under EFL svn with the -dfb
parameter but it didn't worked either. Though again it worked with
-fb. Seems i have to do something more to use directfb. Maybe i am
basically doing something wrong. I am not sure thats why i am asking.
What is the fb and directfb difference?

I asked the question at directfb list one of them suggested to install
the latest stable directfb that is 1.2.6. Current one at the hardy
repo is 1.0.1. İf i want to install the 1.2.6 from source, how can i
install it with the same location of 1.0.1 files. I dont want to use a
double version of directb. I think configuring with prefix /usr should
be fine but i want to be sure. Also i have some other libraries that
are compiled by directfb enabled. Do i need to recompile them again
after installing 1.2.6?


Thanx.
