Problem: Watching flash in a web browser screen the goes off after 15 minutes or so.
Yes, I have turned off all screensavers and power management in both OS and Bios. (At least all that I could find.) I've even tried uninstalling both xscreensaver and kscreensaver.
Equipment and distro:
Lenovo Thinkpad #0302-44U
Linux Mint 9 "Isadora" LTS 64bit (Package base Kubuntu, Lucid Lynx.)
System Settings > Screen saver > "Settings" start automatically (NOT checked).
System settings > Advanced > Power Management & Edit Profiles > I went through and unchecked everything, set everything to "Performance" and set all of the dialog boxes to "Do Nothing".
I also checked in my bios at start up for power-saving settings and assured they we off &c.
This problem (annoyance) seems to be quite prevalent with a lot of people complaining about it on a variety of Linux forums.
Thus far I have found two solutions:
1) A script at this http://ubuntuforums.org/archive/index.php/t-1090393.html which I've not tried because it seems insanely complicated for solving such a simple problem, and it's written for Gnome. There was one written for KDE however. I'll go back and see if I can get it to work if no one can come up with a simpler solution in this thread. Also, it's just the script (many versions) and it says nothing about in which directory it should be placed, how to make it active, or how to set the permissions on it--all things I need to know to use it. (I'm not very good with using scripts.)
2) And this http://silviumc.wordpress.com/2011/12/05/how-to-stop-the-screen-saver-in-kde-while-watching-long-flash-clips-in-a-web-browser/ which suggests running the following at the command line:
Code: Select all
while /bin/true; do qdbus org.freedesktop.ScreenSaver /ScreenSaver SimulateUserActivity > /dev/null; sleep 1m; done
Number (2) worked great, however, when I was trying to send the Flash stream out to my TV in the front room via the HDMI port and a long cable--the TV screen blanked out while the monitor on the laptop remained on!
So clearly, the command in number (2) only works for the laptop monitor but not the HDMI port. Oy vei.
Thoughts anyone? And thanks in advance for reviewing this question! :)
