Hi
I have an old Dell optiplex which might have good latency figures. However when I run a program I get a realtime error everytime the screen saver comes on. I am using the new debian Linuxcnc and I cannot find a way to turn tthe screen saver off. Nor can I find anything about power managemnt in the bios. I would appreciate any suggestions.
Thanx
Aaron

Hi
It is nothing to do with Debian Wheezy or Linuxcnc per se, just depends which desktop manager you are using
If you use the bloated piece of c**p xfce which is automatically selected for some reason in the distro, it will use a screensaver.
If you change it for lxde, it won't
This goes through various ways of killing the screensaver with xfce

There have been a few versions of the Optiplex tested
wiki.linuxcnc.org/cgi-bin/wiki.pl?Latency-Test
Remember to check the output from lspci -vv to see which chipset is used and compare it to the list with known SMI problems, some have affected chipsets, some don't

I have got used to having to run xset -dpms
I just found myself wondering if I could add that to the beginning of the LinuxCNC script.

Only trouble is there is no telling what desktop manager / screensaver is in use.
It would be distro or underlying OS dependent, rather than linuxcnc dependent
You would have to script tests to see if it was needed
I have no idea why xfce was chosen for the Debian distro, I loathe it.
Not only does it have a horrible clunky interface, it is a bad choice for a low power machine,
at twice the size of lxde in terms of RAM and 20x in terms of dependencies.
( as you will see if you delete it and then look at the orphaned packages that can all be autoremoved)

I may have been unclear, I was thinking about putting it in my own personal Linuxcnc script.
I suppose it might go in the desktop launcher even more easily. Perhaps I will try it.

If xset -dpms works ok, with the 2.7 branch you could use
an ini entry like:
See commits
ac5ecc5 linuxcnc script: support starting applications
99d4097 linuxcnc script: support arguments passed to APP
Ref: www.linuxcnc.org/docs/2.7/html/config/in...APPLICATIONS-section
an ini entry like:
[APPLICATIONS]
APP = xset -dpms
See commits

dunno what everyone's deal is with xfce. I use it on my personal computer as well. Screensaver settings are found in the app menu(xfce logo) > settings > screensaver.

My problem isn't actually with xfce. I need the xset -dpms with my old 2.6 system running on (I think) Ubuntu 10.04. The screen blanks after a while despite no power management being enabled or screensaver.
As it is a touchscreen this is bad, because there is no way to tell what button I am going to hit when I randomly touch to turn the screen back on.
