 |
|
So I am trying to get acer_acpi functioning mainly so I have control over LCD Brightness... but when I try to modprobe it I get this...
alibox boot # modprobe acer_acpi
FATAL: Error inserting acer_acpi (/lib/modules/2.6.25-gentoo-r7/extra/acer_acpi.ko): No such device
The version of acer_acpi installed is..
app-laptop/acer_acpi-0.11.2
Help? |

I was working on this just now too, and I think the problem is you need to enable WMI, found in ACPI in Power Management in the kernel config.
From dmesg:
| Code: |
acer_acpi: Acer Laptop CPI Extras version 0.5
acer_acpi: No WMI interface, unable to load
|
Problem is, I tried building it in and got the same message. Built as a module, I get an error saying
| Code: |
FATAL Error inserting wmi (/lib/modules/2.6.25-gentoo-r7/kernel/drivers/acpi/wmi.ko): Invalid module format
|
And in dmesg:
| Code: |
wmi: exports duplicate symbol wmi_has_guid (owned by kernel)
|
Are you running a 64-bit system? I wonder if that's my problem...I think a lot of this stuff is 32-bit. CONFIG_ACER_WMI (apparently you should use this and not acer_acpi) depends on CONFIG_X86. |

IIRC, one no longer needs to emerge acer_acpi. I believe it was merged into the kernel as of 2.6.25. Did you enable both WMI and ACER_WMI?
Power Management Options > ACPI > WMI
