I am trying to run a regular XFree86 server on an ATI
radeon 7000, and a second X server on a framebuffer on
a SiS 630 card, using ruby, to have both on screen at
the same time.
I have recompiled XFree86 4.3.0 with the PrefBusID
patch, and in the config for the 2nd X server, I have
set it to use the "fbdev" driver and have set the
"fbdev" option to "/dev/fbX".
I am working with vanilla kernel 2.6.7 with the ruby
patch. I have catted files to both framebuffer devices
to verify that they work. I have enabled 'hackvideo'.
When I boot with support for both framebuffers
(radeonfb & sisfb), without any X server running, I
can start the frame buffer X or regular X.
With both framebuffers, I have set the framebuffer-X
to run on /dev/fb1.
When I start the frame buffer X (onto 2nd display) on
the first display (initted @ boot) I try switching
consoles to login to another shell and run a program
on the X server, the frame buffer X stops updating the
screen. When I run the regular X server first, and
then try starting the fb-X from an xterm, I get an
error message:
(EE) FBDEV(0): FBIOPAN_DISPLAY: Invalid argument
and the server doesn't display anything.
When I loaded support for only the SiS framebuffer and
disabled support for framebuffer console, I was able
to start the framebuffer X without getting the FBIOPan
error message. (running X on /dev/fb0)
But, when I switched consoles on the display operated
by my ATI card (the card initialized @ boot), the
framebuffer X screen turns blue (it does update).
If I Ctrl+C the fb-X, I can restart it and the screen
returns to normal.
What is going on here? Can I run these 2 servers the
way I have outlined?
Should I try a different kernel version (using 2.6.7)?
(I got the ruby-2.6 patch from this mailing list a few
days ago. the patch is dated 2004-06-16, should I try
to get a new one, if yes, from where?)
My ultimate goal is to use XDirectFB(an X server using
the DirectFB library to access the framebuffer), not
XFree86, for my framebuffer X.
XDirectFB accepts a command-line option as to which
/dev/ttyX device to use (not vt or vc).
When I boot my kernel with dumbcon=2 I get:
Console: Colour VGA+ 80x25 vc:1-16
Console: mono dummy device 80x25 vc:17-17
Console: mono dummy device 80x25 vc:18-18
Console: switching to colour ATI Radeon QY 80x30
vc:1-16
Console: Colour SIS 730 100x37 vc:19-34
How does the range of vc's relate to /dev/ttyX
devices?
Does /dev/tty17 == vc17?
