Kubuntu wont shutdown or reboot?


Hi
I am having a problem restarting and shutting down Kubuntu properly.
I have the latest version of Kubuntu running on a 2ghz box with 1 gig ram.
I am suspecting the problem is either linked to my graphics card or my wireless usb dongle as these are the only things i changed settings for since the last reboot.
The graphics card i have is the Nvidia GeForce FX 5950 Ultra.
The default installation chose a driver for this which didnt support the 3d.
I believe this to be a GE Force 4 card(correct me if i am wrong pls) so i chose that driver instead and it made a vast improvement.
The Open GL screensavers now work awesome and general performance is great etc.
When i try to reboot or shutdown it goes to a black screen after a few seconds and just stays there.
I left it a few minutes in case it was slow to shut down but nothing happened and i had to eventually hold the power button down to forcefully shutdown.
The problem with doing this was that it lost the graphics settings i had just changed.
It went back to 1280x1024 resolution when i switched back on even though i had left it in 1600x1200.
At after sorting out the graphics stuff i foolishly moved onto setting up the wi fi, i should have maybe rebooted to check everything was ok.
As a consequence the problem i am having might also be linked to the wi fi install so heres the details of that too.
I have the D-Link DWL-G122 Wireless USB Adapter and used the ndiswrapper stuff to get this working.
This seemed to work nicely at first as i was browsing web sites fine but since that reboot the internet stopped working.
According to ndiswrapper it still knows about the drivers and says the hardware is working correctly.
And according to the network settings it still has the correct SSID and wep key setup but its not working.
I had followed instruction from the following link to get the wi fi adapter working http://www.ubuntuforums.org/showthread.php?t=146018
So there could be 2 issues here or one that is effecting the other.
Anyone had similar issues and could offer any advice to getting it working?
Any help will be greatly appreciated.
thanks

Paul

Isn't this what Kde is attempting to do anyway?

I decided to reinstall as i hadn't installed much at the point i had problems to try track down the problem and think it is linked to kdm.
It happened when i upgraded to the 3d graphics driver for nvidia and then rebooted without any other changes to Kde.
I may install Ubuntu instead of Kubuntu if i can't a resolution to this as the research i have done suggests the same problem doesn't exist with gdm under Gnome.

I figured out why i was getting the black screen problem and thought i'd post thing in case anyone else has the same problem.

To get rid of the problem edit the grub config file at /boot/grub/menu.lst and look for the line

# defoptions=quiet splash

Remove the word "splash" from it and save and exit the file.
Then type

sudo update-grub

This removes the splash screen when you shutdown/reboot but solves the black screen problem

I have had the exact same issue. I am on a Toshiba Sattelite A105-S4134 with an Intel 3945 network card.

The only big changes I have made to the operating system are:

1. did a sudo apt-get update/upgrade
2. Installed AIGLX/Beryl; works like a charm
3. Set my network/interfaces file to not start internet connections automatically, since it was causing my lappy to lag when booting.

For me, Kubuntu will shut down properly if I end the current session first, and then shutdown from the login screen. However, if I try to shut down/reboot while in a session, it will eventually go to a blank screen and sit there. If I press Alt+F2 to try and pull up the console, the kubuntu splash screen pops up, but does nothing. The frozen splash screen pops back up every time I hit Alt+F2.

The first time I tried Azalar's solution, linux stopped booting (thank god for recovery mode).

Anyone have any other ideas?

You ca try adding the option
Code:
acpi=force
option to the end of your kernel line in /boot/grub/menu.lst
so that it looks like this:
Code:
/boot/vmlinuz-2.6.17-10-generic root=/dev/sdb5 ro quiet splash acpi=force
That's what fixed it for me.

For the splash screen problem, maybe the Frame Buffer mode got messed up by the installation of new nVidia driver ...

Edit: I tried removing Alazar's "splash" option again, but this time I gave it a while to work- it shut down properly. Chalk one up for Alazar.

Huge thanks!!!

I also had the same problem with 9.04...2.5 years later...sheesh! nVidia 1.80 driver. When I would shutdown or restart from the gui, the screen would go black and the computer would just sit there. Changing the line from
# defoptions=quiet splash
to:
# defoptions=quiet
and updating the grub menu fixed my problem.

Thanks!!!
