Thank-you for your comments, Tom. Did any of those changes involve something as fundamental as the change from ps to pdf that is happening here? And is your printer a GDI printer, a ps printer, or a pdf printer? In other words, how good of a test is your experience?

I'm pretty sure the ps versus pdf is just the way the print job is handed to the driver that converts it to whatever the printer actually needs. Certainly my Brother HL-2040 doesn't print postscript of any kind natively, it needs HP PCL. My Epson Artisan doesn't even use a native driver from the fedora repos, it is from some place that produced a 3rd party driver for epson. It has worked unchanged through several releases (including fedora 19). -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Chron curiosity
I have this line in /etc/crontab: 30 23 * * * geoff /usr/local/bin/fp.pl which executes the program every day at 2330. The script terminates by executing system 'sudo systemctl start poweroff.target'; Generally this works as expected. However, when I realize that the shutdown happened too soon, and I restart the system, it re-executes the script. Any suggestions as to where I've gone wrong?

retrofitting LUKS encryption on installed system
I've got a F19 installation that I'd like to turn into a fully encrypted system with LUKS. There are many howtos on the web for encrypting a partition, but they all show doing it to /home. the implication is that you need to be logged in as root on the actual system you're modifying, though I don't think that is explicitly stated. That would mean you can't encrypt the root partition itself, since you've got to have an empty partition to work on, then restore its contents from backup. So, my question(s): -can you do it while being booted into a recovery environment? -if not, is there any way to convert the whole thing that I'm not able to figure out on my own (perhaps I'm having a whole series of senior moments) ??? -Or would it simply be best to do a fresh installation?

F18: GDM sometimes won't load desktop
Howdy All, For some reason, there are times when I log into the system and it simply won't load the desktop. The GDM shows me the login prompt, I select my username, enter my password, and it says 'Logged In' with the little green checkmark next to it. But it just sits there. It doesn't load the desktop and the only way to get to the desktop is to restart the system and log in again. This happens with no rhyme or reason. Just 'sometimes' and always at system boot. I'm running F18, fully patched, with XFCE as the DE. Has anyone experienced this? How do I fix it? Thanks!

Well, I have employer VPN information, ssh keys allowing me to ssh into my own home system, and sometimes customer's VPN (and possibly other) information on it too, so for all those reasons it has seemed like encrypting the whole thing would make sense.

You didn't wait a minute for before restarting the computer? ;-) Look at the top of /etc/cron.hourly/0anacron and add logic just like this to your script. Cron is stateless across reboots (as far as I know) and has no way to tell if it already ran.
