Ah, but that is not the full output of xset q, is it?
As Henk (and others) often say, it is really necessary to include the command as given and the full output in the pasted text in the forum, or you leave out some important information.
I will also add that on many systems (at least, AFAIR, on many laptops), the xset q output will change after a period of time.
I suggest you try the following:
Create a file with the following content:
#!/bin/sh
xset dpms 0 0 0
xset -dpms
xset s noblank
Give it a meaningfull name, such as noblankscreen & save it in /bin
Set the permissions rwxr-xr-x
Set it as a login script for each user you want to disable screen blanking on.
Log out, log back in, or reboot & log in.
Check to see that it all worked by opening a terminal and typing:
xset q
The output should include something similar to the following lines:
Screen Saver:
prefer blanking: no allow exposures: yes
DPMS (Energy Star):
Standby: 0 Suspend: 0 Off: 0
DPMS is Disabled
Note that this will be reset each time the system is hibernated, or goes into sleep mode, or you lock the screen, so after resuming from these states, drop to a console and issue the command:
noblankscreen
or whatever name you gave to your script file.
Let me know if that solves your problem.
