Advanced power management settings....how?
 

What settings would you apply to APM for this issue? I am having a few minor issues with screen not resetting properly when computer goes into "semi-sleep" mode, meaning when monitor shuts off, it does not reset properly. I want to adjust this so when on battery power, machine does not sleep.

I would of put this in laptop forum, but I think it is a software issue.

Thanks.

if it is a laptop.... you may cosinder look into acpi,

apm doesn't have as much support on laptop compare to acpi

Here is the ACPI section of my config file...any suggestions, or am I looking in the wrong place? Is there a configuration tool in Red Hat for this, or is this a manual deal?

#
# ACPI Support
#
# CONFIG_ACPI is not set
# CONFIG_ACPI_ENABLE is not set
# CONFIG_ACPI_HT_ONLY is not set
# CONFIG_ACPI_DISABLE is not set
# CONFIG_ACPI_DEBUG is not set
CONFIG_ACPI_AC=m
CONFIG_ACPI_BATTERY=m
CONFIG_ACPI_BUTTON=m
CONFIG_ACPI_FAN=m
CONFIG_ACPI_PROCESSOR=m
CONFIG_ACPI_THERMAL=m
# CONFIG_ACPI_ASUS is not set
# CONFIG_ACPI_TOSHIBA is not set

And here is APM section:

CONFIG_APM=y
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
# CONFIG_APM_DO_ENABLE is not set
CONFIG_APM_CPU_IDLE=y
# CONFIG_APM_DISPLAY_BLANK is not set
CONFIG_APM_RTC_IS_GMT=y
# CONFIG_APM_REAL_MODE_POWER_OFF is not set
CONFIG_AMD_PM768=m
# CONFIG_BATTERY_GERICOM is not set

Thanks.

do you have kernel source?
if you have kernel source, go to:

/usr/src/linux

and type: make xconfig

you will be given open to change your value of your acpi kernel,

remember disable apm if you use acpi,

if you change value under /usr/src/linux make sure recompile kernel
so your kernel will take effect....


detail how to compile kernel, check:

The provided link hit a dead end when it comes to determining APM or APCI. I am not sure what mine uses, but the BIOS utility says that operating systems using APCI override any settings in BIOS. As for bootup, I can clearly see APM daemon loading. I believe it is in kernel, as modprobe apm comes up negative.

As for function, my problem isn't that there is no power management; seems to be working as screen does shut down, and battery meter in gui is running properly. It is more a matter of getting back to normal screen res after I touch a key, etc.

Any other thoughts would be greatly appreciated.

acpi is more then just power management, it has more function, especially design for laptop.
the only other reason i think think of... is Xfree86 setup, but i doubt it has to do with your screen setting, because you said your screen is fine before going to idle, and it start messed up when u come back from idle, thats exactly why i'm thinking maybe it has to do with acpi
