Dear devs,
I own a Lenovo Thinkpad Edge 13" (intel cpu model), running openSUSE 12.1
64bit.
The screen on this laptop has 16 levels of brightness. However,
thinkpad_acpi reports only 8 level brightness support:
xxxxxxxx:/home/xxxxxx# dmesg | grep thinkpad
[ 21.025163] thinkpad_acpi: ThinkPad ACPI Extras v0.24
[ 21.025168] thinkpad_acpi: http://ibm-acpi.sf.net/
[ 21.025172] thinkpad_acpi: ThinkPad BIOS 84ET27WW (1.11 ), EC

[ 21.025175] thinkpad_acpi: Lenovo ThinkPad Edge, model 0217A21
[ 21.035052] thinkpad_acpi: detected a 8-level brightness capable ThinkPad
[ 21.035499] thinkpad_acpi: radio switch found; radios are enabled
[ 21.035520] thinkpad_acpi: possible tablet mode switch found; ThinkPad

[ 21.037860] thinkpad_acpi: asked for hotkey mask 0x04018070, but
firmware forced it to 0x00018070
[ 21.037966] thinkpad_acpi: setting the hotkey mask to 0x00ffffff is
likely not the best way to go about it
[ 21.037970] thinkpad_acpi: please consider using the driver defaults,
and refer to up-to-date thinkpad-acpi documentation
[ 21.055300] thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is
unblocked
[ 21.074110] thinkpad_acpi: rfkill switch tpacpi_wwan_sw: radio is
unblocked
[ 21.088233] thinkpad_acpi: Standard ACPI backlight interface available,
not loading native one
[ 21.088440] thinkpad_acpi: Console audio control enabled, mode: monitor
(read only)
[ 21.097560] input: ThinkPad Extra Buttons as
/devices/platform/thinkpad_acpi/input/input7
Actually, while i'm in console/terminal i do get to use all 16 levels of
brightness regardless of what thinkpad_acpi is reporting.
Strangely, after loggin into kde/gnome i'm stuck with 8 levels only (Could
be due to the 8 levels of brightness reported by thinkpad_acpi)
Can thinkpad_acpi correctly detect the 16 brightness level screen?
All be happy to provide any info you need.
best regards,
Carlos Bessa
