[Bug 44008] Re: Shutdown still doesn't turn off my computer

[Luis Lumbreras Picazo]

I have the same problem, but it seems to be a "gdm" problem, not related
with acpi nor with "apm"... le te mexplain why:

If i tell it to hybernate it power off at end of it and when powered on again it resumes well.
If i tell it to shutdown it does not power off at end, but hey only if gdm was running when asked.

More detailed:
If gdm is running and i open a terminal window: no way to power off after shutdown, none commands: shutdown, halt --poweroff,... none works
If gdm is running and i press Ctrl+Alt+F2 to go to a console at full screen (text mode), but i let gdm running: no way to power off after shutdown, none commands: shutdown, halt --poweroff,... none works

But, if i press Ctrl+Alt+F2 to go to a console at full screen (text mode), and do:
#sudo /etc/init.d/gdm stop
So gdm is stopped then after few secconds i can confirm it is stopped with [ps -A | grep gdm], so i ask to shutdown with:
#sudo halt --poweroff
Or with shutdown,... all of them at end turns off the power and power off the notebook correctly.

I have seen on Internet a lot of forums on where they tell something
about acpi=force, apm=power-off,... on /boot/grub/menu.lst also about
adding apm to modules,... etc. none of that works for me.

And i found that if gdm is not running when calling shutdown it power
off correctly.

When i was using Ubuntu Intrepid Ibex and Ubuntu Jaunty Jackalope it
allways power off correctly, but when i updated to Ubuntu Karmic Koala
it starts to not do the final power off when shutdown... now i know the
cause is gdm running when calling shutdown.

Maybe it is related in some way with Kernel or with propietary ATI
graphics driver...

Also i can see some near identical lines (more than ten) on /var/messages at the end of it with this error:
Kernel: Assertion fail in ../../../../../../../../drivers/2d/lnx/fgl/drm/kernel/hal_rs780.0 at line: 53

I do not know if such error is related with the shutdown problem, but is
the last error logged and it is at end ot /var/messages no more lines
after it... but i can only see it when not powered off correctly, if i
do the trick of stoping gdm it does not appear.

Hope this can help someone to fix-it. Till them i will do the trick of
Ctrl+Alt+F2 -> login -> password -> sudo /etc/init.d/gdm stop -> sudo
halt --poweroff

Note: 
After doing such, i powered on again and then after some hours of work i press shutdown by mistake (did not remember ro do the trick "stop gdm then halt --poweroff") but what surprise! it turns off the notebook correctly... so when i have time i will re-check if it was only once or can be reproduced.

I mean: 
-Power On, then tell destop menu to shutdown normally and check if it turns off.
-If not force turn off, then turn on again, do the trick of stopping gdm and halt --poweroff, then power on again then tell destop menu to shutdown normally and check if it turns off.

But i will not have time till weekend, so if any one can also check
that, it would be great.

SOLUTION THAT WORKS FOR ME: 
Ctrl+Alt+F2 -> Login -> Password -> sudo /etc/init.d/gdm stop -> sudo halt --poweroff
