[Buildroot] xserver help

[Will Wagner]

Hello,

I'm trying to get the x.org server up and running for an x86 target with intel 945G 
graphics chip.

I have been running into a number of errors and was hoping for some help.

First off I am not sure which packages I should select, there are a lot of packages and I 
have no recent experience with x11. Does someone have an example configuration they could 
send me so I can see what packages you are selecting? Is there anywhere with documentation 
on all the packages and which ones are needed to get the xserver running?

Any help much appreciated.

Will

First you need to decide whether you want to use the tinyX (also known as
kdrive or framebuffer X) or the modular X.org server. Then you need the X
libraries, I would just select them all, unless your file system space is
limited. Then select the fonts you want. And last, if you are building the
modular system, you need the xdriver_xf86-video-intel for your video, then
the mouse (xdriver_xf86-input-mouse) and keyboard
(xdriver_xf86-input-keyboard) drivers. You will need to create an xorg.conf
file for your system as well, and save it to /etc/X11/xorg.conf. I think
there is an example in the default target skeleton directory in buildroot.

On your first boot you will also need to run fontconfig to build your font
cache, or it will take bloody ages for any applications to start in X. Make
sure your fonts end up in /usr/share/X11/fonts, or make a symbolic link to
them from there.

Regards,

John

I need modular X.org

Have done all this. Not sure which X applications I need.

I am able to create a config file with X -configure

I could not find any examples in buildroot

When I try starting X I get the following:

# X -config xorg.conf.new
_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/vip:0
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6

Looking at what is in the root filesystem there indeed doesn't seem to be a fixed font 
folder but I can't find a package that would add them.

I have lib fontconfig built but there is no application fontconfig. Do you mean you have 
to run the fc-cache command?

Also buildroot puts all the fonts into /usr/lib/X11/fonts but adding the sym link doesn't 
seem to help. Seems like all the font paths are a bit messed up and not sure quite where 
they should reside.

I guess this isn't a buildroot problem per se and so I'll try on the freedesktop list.

Thanks for your help.
