what happens if you dim at 1 minute and then not turn off the display?
----------It works just fine if the display is not turned off, no issues with change in brightness
and, do you have this same setting for all variations:
wall power + Performance
battery + Performance
wall power + Powersave
battery + Powersave
wall power + Aggressive Powersave
battery + Aggressive Powersave
---------------- Yes,it’s the same for all the combinations
and, do you have a “screen saver” also running? just to make sure it is
not the bad actor here, i’d suggest either turn off all screen savers
and see what effect that has…
------------- Screensaver is not turned on,it is OFF
and, further to Knurpht’s suggestion, after yours “freezes” what happens
if you press the laptop’s space bar…
------------Nothing happens, screen still remains OFF
and, by the way: please define what you mean by “freeze”…that is after
your two minutes, which of these do you see/hear:
- the hard drive LED blinks occasionally (maybe once in 5 minutes?)
- a LED shows the battery is discharging (maybe red?)
- a LED shows the battery is charging (green or blue?)
- no LEDs are lit
- you can hear the fan
- you hear nothing and see no LEDs
---------- 1,2,5 positive
if you press the space bar what do you see?
------------- Screen still turned off, checked it by connecting it to an external display(Monitor)
if you check your BIOS settings do you have any power saving settings
there? how are they set? if you turn off all BIOS power savings
settings, does that then allow the operating system to do the things you
tell it to (in the Power Management space) without causing a “freeze”?
-------------No power saving settings are enabled in BIOS
did you have this same problem before you installed the ATI driver?
----------------Sorry, I haven't checked it before installing driver
did you run any other version of openSUSE on this machine, without this
problem? (which?) or, any other Linux (which?)
-----------No, am new to SUSE. I used Ubuntu 11.04(Gnome) and 11.10(Gnome) on this machine and everything was fine
what were the results when you tried booting with systemv instead of the
default systemd? (at the first boot screen press F5 and select)
----------------- Yeah !!! This worked. No issues when booted systemv
read the caveat in my sig, then consider this: what are the results if
you add any of these to the Boot Options line on the first green screen
during boot:
acpi_osi=Linux
acpi_osu=Linux
acpi_backlight=vendor
acpi=off
noapic
nolapi
use only one at a time…
------Now, i don’t know wether to check this lines or not because am worried and i don’t want to mess up by doing any mistake
