Hi

I am running Lenny/Testing and with the recent package updates a new set  
of kernel headers was installed which has completely screwed my nVidia  
driver settings. I had to reboot into 2-6-24 rather than the 2-6-25 in  
order to get GDM to work.
    

This I don't understand. AFAIK the headers are used only when compiling, 
how could updating them screw with nvidia driver *settings*? Maybe some 
other packages were upgraded as well?

  
When I went to change the sources list to enable me access the  
appropriate nVidia driver from the Sid repositories using apt, there  
were any number of packages that apt wanted to install as well,  
alongside the nVidia.
    

Of course. Apt will always want to install the newest package, but 
according to priority, see below.

  
What is the correct syntax to ensure that when I am wanting to install  
the nVidia driver from Sid I limit it to *only* the package(s) I am  
seeking rather than everything else that apt wants me to install? I've  
spent the last 1/2 hour or Googling this and I can't find an answer.  
Perhaps my search string is incorrect, but even so if anyone is able to  
assist me, that would be great.
    

Add a line like this:

APT::Default-Release "testing";

to your /etc/apt/apt.conf. If the file doesn't exist you can create it.  
The you can use 'aptitude install -t my_sid_package' to install a 
package from sid, but also any required dependencies.

You can check the setting works by running 'apt-cache policy'. You 
should get priority 990 for testing and 500 for unstable.

Andrei
  
Thanks for the tip Andrei. I have yet to apply it, but am keeping a list of potential fixes to use over the weekend when I have some downtime.

Appreciate your input.

Cheers

Andy
