 |
|
Hi all,
since KDE 4.2.2 I've got a problem with Powerdevil... in fact, nothing works
Everything is ok in the kernel. I installed polyckit. I'm in plugdev group.
But :
- I cannot even suspend
- I cannot manage the screen brightness
- etc...
Did I forget something ? I don't know...
As anyone an idea ?
Thank you by advance |

| I went through the gentoo power management handbook and set up acpid, hibernate-script, laptop-mode-tools and cpufreqd. I didn't bother with the kde power management stuff other than for the monitor. |

|
|
I've just installed a new laptop and I've got similar issues to the first poster with powerdevil and KDE4.2.4.
I've configured the kernel for allowing suspend to disk, suspend to ram, and associated acpi options however powerdevil doesn't detect any options enabled for power management and also the battery isn't shown as being present either.
I know I've probably missed something that is required between KDE and the kernel, but I can't find any documentation on how powerdevil works and what it's looking for and where.
Could anyone point me at the technical documentation for powerdevil as google has failed me? |

This probably won't solve everything, but you need to make sure that both hald and dbus are running in order for the power monitor to work.
| Code: | /etc/init.d/hald start
/etc/init.d/dbus start
|
Hope this helps. |

I've got both hald and dbus running.
I tried logging in as root rather than as a user and was surprised to find that both suspend/hibernate and the battery monitor worked under the root user.
It's almost certainly a problem with permissions and user accounts. I just need to find out where now. |

| This is probably a shot in the dark, but what are the permissions for the files in /proc/acpi? |

It wasn't completely related to the file permissions on the /proc/acpi directory they are
| Code: | ls -la /proc/acpi
total 0
dr-xr-xr-x 11 root root 0 Jun 16 22:27 .
dr-xr-xr-x 119 root root 0 Jun 16 22:27 ..
dr-xr-xr-x 3 root root 0 Jun 16 22:37 ac_adapter
dr-xr-xr-x 3 root root 0 Jun 16 22:37 battery
dr-xr-xr-x 5 root root 0 Jun 16 22:37 button

dr-xr-xr-x 3 root root 0 Jun 16 22:37 embedded_controller

I've recompiled the computer after setting the USE flags for policykit and consolekit. The battery now appears as do options to suspend and hibernate, however whilst the battery monitor shows the state of the battery, suspend and hibernate don't work.
I think I need to find some more stuff to read about how permissions propagate between hal, dbus, policykit, consolekit and powerdevil. The problem that I'm finding at the moment is that it does not appear to be too well documented anywhere though. |

Hi, I was in the same trouble and putting "consolekit" + "policykit" uses in make.conf and then do a "emerge -uDNav world" it fixed the problem. The significant rebuilded package was "hald".
Now I can monitor my battery and suspend my laptop.
Thanks.
PN: This tread can be tagged as SOLVED. Isn't?

Can you adjust screen brightness? I can see battery status and also I can set screen brightness with fn+up/down keys, but setting brightness with powerdevil doesn't work. Also dimming in power management doesn't work, on the other hand cpu clock scaling is ok. Actually nothing regarding screen in powerdevil profiles doesn't work, neither standby/suspend after x time.
What is pretty weird to me is that options which I set in Display -> Power control work, but settings in profiles have no effect.
Any idea? |

My LCD brightness works. You have to have it enabled in your kernel. Have you set these?
| Code: | CONFIG_BACKLIGHT_LCD_SUPPORT=y
CONFIG_LCD_CLASS_DEVICE=y
ACPI_VIDEO [=y] |
There might be some more dependencies, you'll have to check it out.
BTW: FN brightness keys are a bios function.
