Quick notes on setting up XBMX on an old laptop from a txt based Hardy install...

Install linux-restricted-modules & nvidia-glx-legacy 

Set xorg.conf as [[linux:ubuntu_and_debian:working_xorg.conf_for_hi-grade_ultinote_m6600]]

== To get GLX working... ==

Add:
<code>
Section "Extensions"
Option "Composite" "Disable"
EndSection
</code>

To xorg.conf

== Sound ==

Install alsa & alsamixer\\
sudo aptitude install linux-ubuntu-modules-`uname -r` linux-generic\\
and restart


== Overcome the glXGetProcAddress error ==

The nvidia driver I'm using does not have glXGetProcAddress (is this the same for all of them?), rather it is replaced by glXGetProcAddressARB.

There is a solution documented here: http://xbmc.org/forum/showpost.php?p=248010&postcount=55

You can write a wrapper which wraps glXGetProcAddress() to glXGetProcAddressARB().

Save the following as libwrap_gl.c

<code c>
/** Wrapper to map glXGetProcAddress() to glXGetProcAddressARB()
  *
  * Compile : gcc -fPIC -shared -o libwrap_gl.so libwrap_gl.c
  * Usage   : LD_PRELOAD="/path/to/libwrap_gl.so" <executable>
  **/
#define _GNU_SOURCE

extern void* glXGetProcAddressARB (const unsigned char*);

void* glXGetProcAddress (const unsigned char *procName)
{
        return (glXGetProcAddressARB (procName));
}
</code>

Open a terminal and compile it with:

<code>
gcc -fPIC -shared -o libwrap_gl.so libwrap_gl.c
</code>

Preload the library and start xbmc with:

LD_PRELOAD="./libwrap_gl.so" /usr/bin/xbmc

For this to work, libwrap_gl.so has to be in the current directory. For a more permanent solution you can copy libwrap_gl.so to /usr/lib/.

Then edit /usr/bin/xbmc and change the line:

<code>
exec /usr/share/xbmc/xbmc.bin $*
</code>
to:

<code>
LD_PRELOAD="/usr/lib/libwrap_gl.so" /usr/share/xbmc/xbmc.bin $*
Temar
