Hello Vaio-Z-List members, during the last months i have been using Karmic (since its first bleeding-edge alpha) and much have been changed since Jaunty. One important thing is the more 'pure' usage of Upstart as process management deamon (replacing more and more the /sbin/init scripts). I just now have installed the last sony-laptop module (0.9np1) as published by Norbert Preining [1] on a VGN-Z21MN_B (the one without wwan and fingerprintreader and 1366x768 graphics). I saw that there are different outputs from lspci on different models, so I had to change the init-scripts a little bit for autodiscovery. [2] Finally i wrote a script called:
/etc/X11/switch-x-to {intel|nvidia|load-nvidia-settings} [3]
that must be invoked with one of the three arguments between the "{ }".
the first two arguments are self explanatory, the last one I use to load
my nVidia Settings as I manage them in the settings-Manager from nVidia:
sudo apt-get install nvidia-settings
that makes a complicated xorg.conf file unnecessary but one have first
to run the nvidia-settings manager and setup a rc-file, save the
settings you want to restore on reboot and enter the path to that
rc-file in the top of the 'switch-x-to'-script.
Now I invoke this scripts with the Upstart mechanism with the
file /etc/init/gdm.conf. in the 'script'-part of that file, in the
beginning, directly after
respawn
and before
script
I have added this 'pre-start'-section:
pre-start script
gc=nvidia; lspci|grep -qs nVidia || gc=intel
/etc/X11/switch-x-to $gc
end script
and after the end of the 'script'-part, just after
end script
I have added this 'post-start'-section:
post-start script
[ x$gc = xnvidia ] && /etc/X11/switch-x-to load-nvidia-settings
end script
at the end of the file.
Maybe some of you like my approach to solve this.
