Why doesn't my YUM work and 3 other questions

[Ken Simpson]

Installed YDL 3.01 about a week ago with no hitches (only OS on the system so 
no anaconda probs). However yum doesn't seem to be working.

YUM update doesn't seem to do anything. It doenloads the headers etc but then 
says there is nothing to update when i know there is a kernel update to do at 
least. I have downladed the new kernel rpm's and installed them by hand when 
yum update kernel didn't work either. Any ideas?

Second, is there any way to slow down the pause on the key repeat? I am often 
typing more than one letter becaause I am holding down the key fractionally 
too long. I can't find where to adjust this

Third, I have downloaded and installed kde3.2. It's very nice. I have had a 
look and seen there are no YDL rpm's for a proper setup, but can anyone point 
me to where the kde path variables are set? I have checked /etc/profile 
/etc/bashrc.

Finally, how do I turn off the booting into the graphical screens. I want to 
log in and then type startkde to get everything going.

Thanks for any help you can give
