Re: KF 5 & Plasma

I guess, I'll jump in with the rest and write my problem too.

Plasmashell is leaking something. I think - timed events. After I starp plasmashell I get ~ 3% cpu usage (@800MHz). After ~40min it is constantly using ~ 10% ... after 2hours its around 30% @2Ghz. killall plasmashell && plasmashell -s fixes it. It returns to ~3%. Does anyone is seeing this or I'm special? I tried plasmashell-git (with rest of git stuff), but it's the same there. Strace shows large number of calls to futex.

I'll try to run it through cachegrind with unoptimized build in weekend, to maybe catch, what is eating my resources, but maybe anyone already know, what is the problem?

Anyone knows how to see in the system tray the wicd-gtk notifier?

Re: KF 5 & Plasma

On a Samsung netbook which I have running kf5/plasma without any of the old kde4 packages - the system boots to the sddm greeter, and it does login to the plasmashell. However when entering the password into the greeter it has always been very slow to respond with the line of blobs for each character of the password taking some seconds to fill the password field once entered - it does then log in. I have tried changing the greeter theme but this slowness to respond to the password entry remains.

I have a UK keyboard/locale but that should not make any difference.  I also did not install the plasma-meta package has it has a dependency on ksshaskpass which does not seem to work, and I use opensshaskpass instead that works properly for me.

Does anyone else see this, and if so is there a workaround?

Re: KF 5 & Plasma

FYI, my issue with SDDM was fixed by this commit: https://github.com/sddm/sddm/pull/358. The tweak can be applied manually to /usr/share/sddm/scripts/Xsession. For me, SDDM responds quickly. The response to my keystrokes is as expected.

Re: KF 5 & Plasma

Anyone else got the problem that basically all Qt5 apps that accept text input are
- slow as hell (kate makes me feel like I'm on a 286)
- receiving text input in reverse order when using fcitx?

With fcitx disabled, at least the letters appear in the order I type them (so it's probably a bug on their side), but I can't believe a 3.8 GHz Phenom is too slow for simple text input.

Using fctix on my exprimental machine, as well as plasma. Neither slowdowns on text input so far, nor "mirroring".

Here is a fun one. QT Open/save file dialogs cause the program to crash/hang. Dolphin works just fine. It *looks* like file dialogs are trying to open the trash.

How do I install the colour picker widget? For KDE4 this was provided by kdeplasma-addons-applets-kolourpicker

There is no color picker plasmoid yet for Plasma 5. I'm using a standalone app (slickpicker, it's in the AUR) until the plasmoid picker is ported.

Are you using Nvidia blob ?

Strange, there's mentions of it online e.g. http://git.net/kdelibs-bugs/dsc14725.html from a year ago.

That's about the color picker used in applications (eg when choosing desktop background color), not about the plasma applet.

Yes, I have them already installed:

pacman -Qs libapp
local/libappindicator-gtk2 12.10.0-4
    Allow applications to export a menu into the Unity Menu bar
local/libappindicator-gtk3 12.10.0-4
    Allow applications to export a menu into the Unity Menu bar

Re: KF 5 & Plasma

I don't suppose anyone's come across or figured out how to fix the issue I posted about previously here?

I still haven't managed to figure out how to fix it yet.

Edit: Just as I posted this I found a post related to the issue in another thread here

Re: KF 5 & Plasma

dropbox use a embeded qt5 installation, i've tried to edit the installation to use a system Qt5, but the icons still don't work (if they used an edited version)

in a 3.2.4 changelog, the dev's says are working with the Qt dev's to solve the problem

https://www.dropboxforum.com/hc/communi … 2-4?page=1

greetings

There are 2 versions of Dropbox, one in the official repos and another in AUR. In this official version 3.0.5-1 and 3.2.6-2 AUR exists which is apparently solves the problem of icon, which in my case was not so.

regards

Re: KF 5 & Plasma

How do you restart/reload plasma? On KDE4 this was a simple case of running

$ plasma-desktop

On KDE 5 this command doesn't exist. It was also possible to restart kwin with kwin --replace

I'm having occasional crashes where plasma desktop crashes and the only way to get it back is a reboot

Re: KF 5 & Plasma

I tried again today to migrate from kde4 to plasma without any success. I stay stuck with SDDM which is no more launched this time. I did not intend to do this, but I think that I am going to wipe out Archlinux and reinstalling it all this week-end. Is there any to do limit the damage and restrain my reinstall to just the desktop environment?

I also get a strange complaint about "Unknown CMake command 'plasma_install_package'"...

I am a little bored with all these bugs. I hope that reinstalling will work, even if it means spend 6 hours to reconfigure it entirely.

Now there is a choice.  Either kwin_x11 or kwin_wayland and  --replace.

plasma_install_package is in /usr/lib/cmake/KF5Plasma/KF5PlasmaMacros.cmake which is provides by plasma-framework

Re: KF 5 & Plasma

Ekaradon, I'm not sure what problem you're having with SDDM, but if you're using ZSH, there's a known bug in SDDM that can be fixed as I described in an earlier post.

Re: KF 5 & Plasma

Anyone else trying to make KDE run scripts on shutdown? I can manually execute them (and see the message they create in the journal), but they're seemingly not being executed on shutdown...
