 Posted: Wed Mar 23, 2011 9:25 am Post subject: kernel 2.6.38 disables some functions of my asus-laptop |
 |
|
hiho
i tried the new 2.6.38 kernel (x86_64, gentoo-sources).
i builded in the "Device Drivers --> X86 Platform Specific Device Drivers --> Asus Laptop Extras" and "Device Drivers --> Hardware Monitoring Support --> ASUS ATK0110".
ok, now the problem: On my old kernel (2.6.35, x86_64, gentoo-sources) i could change the brightness of the display and turn the whole display off via some keys. as far as i noticed i could not catch that as events in linux.
Now the keys have no effect anymore, i can dim the display over /sys/class/backlight/asus_laptop/brightness. The turn "off the display" - button turns now only the backlight off - the content is still visble...
everything else seems to work normal 
does anyone have an idea how i could restore the old behavior? ( the keys are really disabled, i cant see them in xev when i press them  )
thanks

| To be clear, had you also used that kernel driver with the old kernel? You might try not enabling the driver and perhaps the BIOS ACPI will provide those functions then. |

seeing you're post I just checked for my asus (N80VN) with nvidia.
Since quite some time I had my kernels setup with
CONFIG_ASUS_LAPTOP
and
SENSORS_ATK0110
got now 2.6.38
One thing I know my shortkey for display brightness used to work and now they don't .
I don't know if it's since kernel 2.6.38 as I don't use this function that much but.
note on the side keybinding works for volume.
are the volume key ok for you too? |

mhh i just checked the setup for my old kernel: and i builded in the EEEpc hotkeys so i guess i will give them a try (i did not build in ASUS_LAPTOP and SENSORS_ATK0110 in 2.6.36) but i tried to build my new kernel without them - without success.
so i will go now and give the eeepc thingie a try 
@jms.gentoo:
do you mean the extra keys? they work fine for me, as well on the extra keyfield-thingie and on the keyboard (with fn). its just the backlight |

Do the backlight keys generate ACPI events with 2.6.38?
You can check that by running acpi_listen and pushing some of the shortkey buttons.
It looked like this on my Asus UL30 after pushing the backlight and volume buttons.
| Code: | sandman@quark ~ % acpi_listen
hotkey ATK0100:00 00000023 00000003
hotkey ATK0100:00 00000022 00000004
hotkey ATK0100:00 00000013 00000004
hotkey ATK0100:00 00000014 00000003
button/volumedown VOLDN 00000080 00000000
hotkey ATK0100:00 00000031 00000015
button/volumedown VOLDN 00000080 00000000
hotkey ATK0100:00 00000031 00000016
|
btw, acpid has to be running for acpi_listen to work. |

1-brighten +(fn+F5)
2-brighten -(fn+F6)
3-mute(fn+F10)
4-unmute(fn+F10)
5-volum+(fn+F11)
6-volum- (fn+F12)
mute ,volum -+ ok and work as well without acpid
but brighten+- does not work
backlight=brightness right?
@axlalf
I mean the hot-key fn+ whatever
for me they works fine for volume+- ,mute,num lck
but don't for brightness
for the extras button/key
-button Bluetooth on/off works
-button wireless on/off doesn't nor does it with fn+F2 (and as far as I can remember it never did for me) |

mhh the wlan key works fine for me...
mhh maybe there is just something wrong with my acpi
| Code: | $acpi_listen
acpi_listen: can't open socket /var/run/acpid.socket: No such file or directory
|
the extra keys work fine - beside the strange white circle with 3 dots ^^ but thats no problem...
all my keys work fine - just the backlight -.- |

the new toshiba laptop extras and toshiba modules of this kernel work for my tecra M2
so far after kernel 2.6.24 they have never worked for me till this time
though i have to run fnfxd and fnfx to work with toshiba function keys
some acpi functions are not working, like battery control method[option is not present]
| Code: | localhost ramaswamy # acpi listen
Battery 0: Full, 100%
localhost ramaswamy # acpi_listen
acpi_listen: can't open socket /var/run/acpid.socket: No such file or directory
localhost ramaswamy # acpid start
localhost ramaswamy # acpi_listen
battery BAT1 00000080 00000001
|
what does this mean it keeps listening
