Since the list is talking about slock, now might be an appropriate time for me to mention again my xss project:
http://woozle.org/~neale/src/xss/ This provides several single-purpose programs which allow you to build a screen locker (or just saver) with a shell script. I set mine up to check the entered password against an md5 hash of my password: this means there's no need for suid root. At work, it runs kinit and unlocks on success; this has the nice property of getting me a new kerberos ticket at the same time. When I mailed the list about this in April someone responded with a neat thing called "sinac", which is a little smaller than xss, but polls, and only replaces one of the 6 programs in my package. Some folks may prefer it, combined with slock or xlock: http://lists.suckless.org/dwm/0804/5534.html Neale
