Yesterdays updates went fine and ran ok.
Then this morning trying to get the updates the mouse and screens get the jitters.
I downloaded the new upadtes and yum quit.
I rebooted and now the checksums won't let me into the mirrors.
and then the mouse started going nuts again.
I telinit 3 - no prompt, I Ctrl-Alt-F1 and login as root
yum clean metadata
yum update got back to the install step
rebooted with the new updates, mouse is really going nuts.
System monitor seems to have a mind of it own but I could see several taks running high.
I opened System, pref's, mouse and started clicking on things, then
when I clicked on the light buld the mouse settled down.
After several clicks I closed it and all seemed to be ok.
I open services and stopped all I didn't need.
Bluetooth, ISDN, CPUsped
Everything seems to be ok now, won't know until I reboot again.
