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.
