Hello. I tried various ways to stop the laptop screen from being
shutting down, as I use this screen to watch debug message of an
application I am working on, I need monitor always on, no screensaver,
no blank, no dpms etc.
I cannot do it. I have tried:
1. set blanktime to "NO" in /etc/rc.conf
2. set saver to "NO" in /etc/rc.conf
3. start X server and run a terminal in it, run xset -dpms
4. check laptop BIOS setting (there is no setting for automatic
blank time
I have not tried:
I. remove 'apm' from kernel (I didn't compile ACPI into kernel
because this is an old notebook I am not sure if ACPI works, but
I have compiled apm in kernel, which is not shown in dmesg and
doesn't seem to work, e.g. 'shutdown -p' do not turn off the
power)
II. install Windows on the same computer to see if Windows can keep
the monitor on.
III. boot the system to FreeDOS and see if monitor keep turned up (to
decide if LCD is turned off by hardware or software)
Any suggestions?
