Urgent help needed - desktop/ screen Kubuntu Karmic does not function at all!

[pkaplan1 at comcast.net]

Sounds like an xorg problem related to your (older?) graphics hardware. I had graphics problems with composting off (yes, off) on a machine with Radeon M7500 graphics that was solved by fiddling with xorg.conf. 


You might try copying /etc/X11/xorg.conf from the 7.10 installation to 9.10 and seeing if that changes things. 


Good luck.

I can see that with 1/3 of your screen black it will be just about impossible 
to try work with KDE. I will point you to the relevant file, but I am not on 
Karmic so it might be different.... But you can try. 

Go to a normal command-line (ctrl + alt + F1 or F2 or F3) and login. 
Change to the folder: 
cd ~/.kde/share/config 
Backup the file first: 
cp kwinrc kwinrc.original 
Now use your text editor, nano or vim or whatever you know. Edit the file named 
'kwinrc'. Example: 
nano kwinrc 
In that file, look for the section titled '[Compositing]'. 
Remove any lines directly under it, but not the next section (which will be in 
square [] brackets.) 
That *should* switch the compositor off. To turn it on, try adding these lines: 
GLDirect=true 
GLMode=TFP 

As an example, here is a snippet from my own file: 
[Compositing] 
GLDirect=true 
GLMode=TFP 
GLVSync=true 

[Desktops] 
Name_1= 
... 
Do you see how the 'sections' work here? I hope so :) 

So, decide on or off. Add or remove lines as you can. Save the file. Then 
restart Kwin -- flip back to KDE - use ctrl + alt + F7 or F8 (I can't recall) 
and then logout and login again. 

I hope that helps a little. I still am not sure it will even work.
