For most kernel panics, updating your software is all you have to do.
When I try to install Microsoft visual studio 2015 it gives the error "Setup Blocked".
telling me:"The computer needs to be restarted before setup can continue.
You may experience this issue if you are logged in with a Standard User account.
In order to complete the installation, Windows must execute certain commands that are available only on accounts with administrator privileges.
I typed sudo killall xscreensaver and it seemed to work, no error msg., but then I typed Start xscreensaver and restart xscreensaver all different ways and it says Unknown job: xscreensaver and Unknown job:xlockmore . Will I have to try to fix it manually from a terminal, (boot to recovery) or get mad and re-install 11.10 from my disk? Trying to update a ppc ubuntu install is nearly impossible.
