Comment 5 for bug 59417

I have the same problem in 8.04 hardy heron.

Creating /root/.Xmodmap didn't work for me. Adding "xmodmap -e 'add mod3 = Scroll_Lock'" to ~/.xmodmap as per http://www.nabble.com/Re%3A-Swap-Remap--Ctrl-and-Alt-keys-p17724405.html works, but pops up a dialog for running the addition at login, which is just as annoying.

Beats me why they don't just put a switch on the keyboard somewhere. I've also discovered that ctrl+backspace (no alt) restarts X when scroll lock is on, which caused me to have to re-write this message a few times!
