Public bug reported:
Binary package hint: xorg
Xorg appears to have (hardcoded) a default timeout for blanking the
screen, set to 600 seconds (10 minutes)
If the user tries to disable the screen blanking using gnome-power-
manager (all timeouts disabled, no screen turn off) aswell as the
screensaver being disabled, the screen will go blank after 10 minutes
regardless of the setting.
If you set the blank screen timeout to less than ten minutes, then this
setting is used.
The following is returned when running # xset -q
---------
Screen Saver:
prefer blanking: yes allow exposures: yes
timeout: 600 cycle: 600
---------
Again, timeout is set at 600 regardless what the user configures within
gnome.
Adding the following to the xorg.conf file solves this issue:
---------
Section "ServerFlags"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection
---------
Upon restarting gdm (logout to restart X), the values retrieved by #
xset -q are now correct
---------
Screen Saver:
prefer blanking: yes allow exposures: yes
timeout: 0 cycle: 600
---------
Now, the screen will not blank after a default of 10 minutes.
This occurs on both amd64 based installs of Karmic 9.10 at my current
location. I've also noticed quite a few threads on ubuntuforums which
are also describing the same issue, but with no resolve.
Can the timeout be set during the compilation of the xorg package? Or
will it require constant modification of xorg.conf file to sort this
issue? (not the best idea for novice users)
