Re: [arch-general] [arch-dev-public] KDE 4.8.0 hits [testing]

Hi all, overnight the mirrors synced the latest stable release of KDE.
I had no many time to work on it, so I pushed it in [testing] just to be sure everything's ok. As I can't send to arch-dev-public, I'm sending this here:
This release seems good to me. (signoff x86_64 ?) I've been using the packages available in kde-unstable, and I must say the packaging is well done! Good job! Tim

First off, New arch user here (was with redhat/fedora since about RH3 or so) - decided to move in this direction ... so far am liking it a lot. Thank you! I'll get more involved as I find my way round and learn the ways ... pre-apologies if I'm not familiar with all the protocols yet .. That said - (1) kde 4.8 - stable and working as its intended best I can tell - tested on 2 desktops and 1 laptop since last night. (2) One smallish potential problem zone on laptop is the new power applet - profiles are gone and it is no longer possible to choose a 'powersave' vs 'performance' via a toggle. If the bug[1] continues where the power applet thinks it is in battery mode after unplugging A/C, but in fact it is not (screen remains bright etc) [2] then the old way of 'fixing' it of hand toggling to performance profile and back to powersave is no longer available (at least via the power applet). So now need a CLI script to avoid battery drain in that case. Seems a step back. There is a toggle to 'turn off power management - useful for presentations on battery I suppose ... tho when I tried it earlier on battery it did not seem to restore performance mode for me ... I need to investigate that further tho'. gene [1] lenovo W520 I7 gen-2 with i915. [2] I had with all prev kde and up to 3.2.1 kernel.

Welcome!

This seems to be working as intended (http://www.kde.org/announcements/4.8/plasma.php), so nothing that we should do anything about (if you think it should change it should be taken up with upstream).

That's an annoying bug (both with CLI and with GUI workarounds imho). If you know where in the stack the problem is (plasma/solid/upower/kernel), please file bug upstream. If not, file a bug at bugs.archlinux.org and we'll try to figure it out :)
There is a toggle to 'turn off power management - useful for presentations on battery I suppose ... tho when I tried it earlier on battery it did not seem to restore performance mode for me ... I need to investigate that further tho'.
If it persists, please file bug :-) Cheers, Tom

Agreed completely - was just making a comment ...

Hello Gene, I have a W520 too and I can share what I did for power management in KDE: - first of all, I suggest you to install tlp [1] from aur - I wrote a little bash script [2] to set cpufreq's governor and lcd's brightness, located in /root/governor.sh - enabled wheel group to use it without password with the following in sudoers: %wheel ALL=(ALL) NOPASSWD: SETENV: /root/governor.sh - in KDE's systemsettings -> power management, I enabled "run script" on profile load, with the following settings: AC profile -> "sudo /root/governor.sh ac" BATTERY profile -> "sudo /root/governor.sh bat" using these settings my laptop correctly switches profile on AC->BAT (and viceversa) events Cheers, Morris [1] - https://aur.archlinux.org/packages.php?ID=48464 [2] - http://pastie.org/3268259

Hi morris: First off thank you for the feedback and suggestion. I just looked at your script - I think you're using cpufreq-set which is being deprecated and replaced by the cpupower tools (in core not AUR) which have these tools: cpupower-frequency-set cpupower-set Do you know how to modify your script to use the new cpupower tools? If I recall right, cpupower was introduced for the 3.x kernel. gene/
cpupower followup: I installed cpupower but a short test for me didn't work .. 1) ls /sys/devices/system/cpu/cpufreqy Is empty .. 2) cpupower -c 0 frequency-set -g ondemand Setting cpu: 0 Error setting new values. Common errors: - Do you have proper administration rights? (super-user?) - Is the governor you requested available and modprobed? - Trying to set an invalid policy? - Trying to set a specific frequency, but userspace governor is not available, for example because of hardware which cannot be set to a specific frequency or because the userspace governor isn't loaded? I need to read more ... to get the right driver installed first I guess.

Lots of great info here .. doh me .. https://wiki.archlinux.org/index.php/CPU_Frequency_Scaling

Morris - The change to your script to use cpupower is trivial: cpupower frequency-set -g $AC_GOVERNOR to replace the 'do i in seq ..' line by default cpupower works on all CPUs. Thanks for help ...

Ok - so now the question is why is the thing not working correctly to begin with - and how do we fix it so we don't need to fix by hand ...

After installing cpupower package - (thanks wiki :-)) and modprobing acpi_cpufreq cpufreq_ondemand and starting the cpopower "daemon" it seems that the screen dimming is working correctly now in KDE - I will check the cpupower frequency state to confirm - and check and check that it continues to work after sleep/resume cycles .. gene
