Screen turns off after 5 minutes (KDE issue?)

Hello. My computer's running Arch with KDE 4.13.0, and since a few days I've been noticing that the screen turns off after exactly 5 minutes. First I thought, well, it must be something in the energy mgmt preferences, so I went to Preferences > Energy Management  > On Battery and I verified that the option for saving energy by turning the screen off is actually deactivated. I've said what the f...? Then I thought it must be the laptop-mode, but after checking the service is actually deactivated. So what? Then I decided to activate the  option for saving energy by turning the screen off in the On battery tab of the energy mgmnt preferences. I set it to 6 minutes. Actually this time the screen didn't turn off after 5 minutes, so I decided to wait a few more minutes, and I verified that after 20 minutes the screen turned off... I don't know what is happening here. I even uninstalled KDE and deleted all the config files, but it still happening the same. It's maybe a bug of KDE 4.13? What do you guys think?

Thanks!

Maybe you could check dmesg and /var/log/Xorg.0.log. Hopefully some output will be produced if the card fails to enable the screen. You should use ssh for this. Or consult journalctl and /var/log/Xorg.0.log.old.

What's the output of 'xset -q'?
