BLack Screen while running X11 on /dev/fb1

[umang gupta]

Hello ,

I planned to run my X11 on 2nd framebuffer device /dev/fb1  in place of fb0
. I have enabled both nodes in kernel and hence I have /dev/fb0 and /dev/fb1
on board  .
I created a conf file
22-xorg-fb1.conf<?ui=2&ik=15cc8556f6&view=att&th=12ce3ab65d4abd3b&attid=0.3&disp=attd&realattid=f_ghofv03f2&zw>in
/etc/X11/xorg.conf.d/ ..that I am attaching here .

When I started X by running startx , I get a black screen . . I got logs as
Xfb1.log<?ui=2&ik=15cc8556f6&view=att&th=12ce3aa298c27345&attid=0.1&disp=attd&realattid=f_ghofoxby0&zw>.

Now I replace conf file with
22-xorg-fb0.conf<?ui=2&ik=15cc8556f6&view=att&th=12ce3ab65d4abd3b&attid=0.3&disp=attd&realattid=f_ghofv03f2&zw>that
access fb0 .. I got X11 seen on screen .  Logs received as Xfb0.log ..

Now I kill X , again uses /dev/fb1 , run startx , it brings X11 up ...


I am not getting why , while using fb1  first time , I am getting black
screen ? Do I need to modify somewhere in X11 source code ?



Thanks :
