[CentOS] CUPS not generating a printcap file

According to all of the documentation I can find, an /etc/printcap file (or whatever filename is specified with the Printcap directive) is generated by cupsd ever time a printer is added or removed. On all of my CentOS 6.7 systems, this is NOT happening. I can restart cups and add or remove printe

[CentOS] Getting confirmation for power button

Using CentOS 5.8: Currently on my workstations, when I press the power button the computer immediately does a 'shutdown -h now' (per /etc/acpid/events/power.conf). Is there a way to change it so that a confirmation dialog comes up, rather than an immediate shutdown? I assume that I am going to n

[CentOS] Disabling user switching in CentOS 6

Installing CentOS 6 on a lab full of workstations, and I want to disable fast user switching. With CentOS 5, I simply made sure that the "user_switch_enabled" entry in /etc/gconf/schemas/gnome-screensaver.schemas was set to false. However, that doesn't work with CentOS 6. I've found various prop

Re: [CentOS] /boot partition too small

If there are many old kernels in there, you can probably remove the oldest one(s) to make room for newer ones. I've run into problems where the yum update didn't work because there wasn't enough room in /boot; my notes for updating now include removing old kernels first before running updates.

I would like to have my lab workstations logout a session after the person has been idle for a certain period of time. After some searching on the web, I got into /etc/gconf/schemas/gnome-session.schemas and set the default value of max_idle_action to “forced-logout”: /schemas
