I totally missed that there's an xorg.conf in this system. I always went straight to xorg.conf.d and was puzzled to only find the default files there. :rolleyes:

I'll give that a try. Thanks!

@systemd:
I don't want to turn this into yet another systemd thread and my knowledge about init systems isn't deep enough to actually judge that matter.
With the dependency situation in the long run I mean post-jessie. The quality of the software in the debian repos varies greatly and my concern is that some packages in the "outskirts" may not be tested enough against a 2nd non-default init system.
I think fso-deviced is a good example. Apparently I'm the only one who has tested it since the systemd transition and there might be lots of other packages which seem to be ok, but are actually simply not used which means nobody notices that they're not ok.

Sounds good.
btw, I had a look at Maemo's power_supply directory and apparently there's no value indication the current charge either. How does Maemo determine the battery status? Based on the voltage?

I'll probably split it up into separate xorg.conf.d files when it gets larger.

In my opinion, well written software should work regardless of the init system that has been installed. If it doesn't work, then a legitimate bug should be reported and then subsequently fixed.

Ok, there we are:
I installed lxde-core without suggests and recommends. lxsession brings a graphical logout via lxsession-logout. This only works with libpolicykit-1 installed which in turn depends on libpam-systemd and therefore sytemd.

edit:
It's the same with libpolkit-backend-1-0 and libsystemd0. I reduced the systemd packages to recommends for both and policykit-1 installed fine.
The logout GUI still didn't come up but segfaulted instead. strace revealed that I had to install lsb-release. The GUI came up but without buttons for shutdown or reboot. I will investigate that later.

edit2:
btw I missed Tab in X11. Since Shift+Space doesn't work as Tab here I remapped @ to Shift+Space and now use AltGr+Space for Tab.

The critical systemd package that will change the init system is systemd-sysv. Fortunately, there's systemd-shim for those of us who don't want to use systemd. libpam-systemd and similar packages will happily install with the shim instead of systemd-sysv.

With systemd-shim, the GUI for logout will come up and everything will work, *except* reboot and shutdown (aka most important things). Don't expect it to work no matter what you do. There is a huge patch apparently fixing many issues (targeted at lxsession package, i believe) send by a non-maintainer over a year ago, but it sits in debian's "mentors" limbo since then, and it doesn't look like situation is going to change, anytime soon.

Might be work trying to compile the 0.4.9.2-1.1 version of lxsession yourself, from the source send to mentors - everywhere I've searched, people mention that it fixes things as advertised, and I find exactly zero claims, that it breaks something else/doesn't work.

WTF? there definitely *should* be one, provided by the upstream bq27x00_battery kernel module. For sure, there is one, when using said module with Maemo (/sys/class/power_supply/bq27200-0/charge_now) and chip provides those information just right.

If module, for some reasons, fails to provide under native debian,an intermediate fix might be to using i2cget directly in a script, just like good'old bq27200.sh script did. It could temporaly do the job in stead ( ;) ) of kernel module, by exposing values to fake sysnode. You would somehow need to direct thing to look there (at your fake sysnode), instead of default one, though...

with regard to missing shutdow options, has user got correct permissions/group?

Correct. Installed systemd-shim, reinstalled policykit-1 and libpolkit-backend-1-0 and the full dialogue came up. Thanks!

Somebody heard you [1] ;)
It's not yet in the repo as a binary, but that should change very soon.

This is from my primary N900 running Fremantle with KP:

This is from DebiaN900:
Code:
$ id
uid=1000(user) gid=1000(user) Gruppen=1000(user),109(netdev)
Do I need more?
I have an old Lenny VM where I'm also in powerdev, but that's neither the case for my Wheezy desktop (Xfce) nor my Jessie VM (LXDE, installed before systemd transition, shutdown not working either)

Edit:
Is there a way to give regular users write permissions to /sys/class/backlight/acx565akm/brightness ?

Edit2:
It would also be nice if the kernel could provide /dev/rfkill

I finally found the courage to install alsa. However it doesn't seem to detect the soundcard:
Code:
# aplay -l
aplay: device_list:268: no soundcards found
And I must confess I'm pretty helpless in tracking this down without having a pci bus.
I guess the modules are fine?:

However, if you dig deeper: http://elinux.org/N900 (search for " All sound alsa switches and channels ") it states that it works only when using kernel from Fremantle and no patches are available for mainline kernel.

Re: DebiaN900 - A set of scripts to facilitate the installation of native Debian (WIP)
 
I missed that note about the kernel. Thanks!

Another issue I came across, at least if you want to use the N900 as a phone is the power consumption. On Debian it needs about 10x the power it needs on Maemo which results in a battery lifetime of about 6 hours.

Sure, this is with wifi (and maybe some other components) always on and there are probably some kernel tweaks missing and the userland isn't configured for saving power either, so I was expecting a higher power consumption. And it would certainly be much better if suspend to RAM worked, but factor 10 is still quite a lot.
