Thanks, @gegechris99. Now i can open regional settings. However, locale scheme is exactly the same i've posted before. Don't know what could be the problem. I found that thunderbird is affected too. Can't attach a file if path to the file contains cyrillic.

Does command "locale" give the same result in KDE5 as in XFCE4?

If there is any difference, please post them.

If there is no difference, you could try to change LC_CTYPE to ru_RU.UTF-8 because :

according to GNU documentation

Locale is the same for both xfce and kde.

LC_СTYPE doesn't solve my problem, unfortunately. No matter, if i set it system wide in lang.sh or pass it before command, like
I've found that firefox is also affected. If i download a file with cyrillic name, e.g. "файл-1.pdf", in firefox download directory i see file "_-1.pdf". That's a real problem for me, because i download a lot of files every day.

Does anybody here have the same case with english(us/gb)+russian locale? If there is any, please contact me to compare configs and other possibly related things.

This might help. Regional settings in KDE5 are saved in ~/.config/plasma-localerc. They were previously saved into ~/.config/plasma-locale-settings.sh.

As you have the issue with KDE5 and not with XFCE4, it might be worthwhile to check content of ~/.config/plasma-localerc and delete ~/.config/plasma-locale-settings.sh should this file exists in your system.

@gegechris99, thank you one more time. I haven't noticed that plasma contains user specific locale file. I made plasma-localerc looks like locale and now everything is fine. Btw, sorry for not answering for so long. I took my time to test everything is ok.

However, the rest of problems with lots of crashes still persists. To avoid this I use a few gtk apps from xfce like thunar, xfce4-terminal, X PDF, xarchiver etc and don't use kde connect and ark. Hope all kde related bugs will be fixed by the time plasma5 officially comes to slackware.

Among many other things,

Some time back there was a post where someone had claimed that
they were able to edit the color settings in KDE5.
There used to be an option in settings that allowed complete colour control
but it was removed during one of the upgrades that included a major change
to how KDE5 runs.
I really can't seem to find any way to edit the colors and although I understand
exactly what RTFM means, the documentation of KDE5 is far from up to date
and is not accurate. I don't want to download somebody's packaged color theme
but I do want to change the standard color themes to something a bit more
suitable for my personal tastes.
Does anyone have any idea how to edit the colors in KDE5?
I've tried the theming tools and found it to be pretty much a dead end
but there has to be some way.

Yes, go to System Settings -> Colours, point the cursor at a theme and bottom right an "Edit Colour Scheme" button will appear.

I found this over the weekend:

Love me some KDE2 window decorations! I was very disappointed to see they were removed.

Brilliant. Would love to see a screenshot...

Good! I was also disappointed that they removed the KDE1 window decoration.

This one I loved a lot.

Sure! Here you go:

I've got a KDE5-related head scratcher which I just noticed.

The system in question has 2 installations of Slackware64-current from last weekend. They were both installed from the same media.

The first one (on sda3) is a full installation, complete with KDE4 and KDEI, the whole box & dice. Clean installation, new user accounts, etc.

The second one (on sda4) is a full installation less KDE and KDEI. These series were 'deselected' at installation. Then the latest version of Alien Bob's ktown was added. Apart from that, this is also a completely clean installation, with new user accounts, etc. I noticed that some of the default packages were upgraded as a result of the installation of ktown.

The issue I'm having is that under KDE5 when I open a terminal and ssh into my old (2008ish) NAS the keyboard doesn't seem to respond properly. Pressing the arrow keys gives me something like AABBCCDD and certain F keys don't respond at all.

This only happens when I'm logged into that server via ssh under AB's KDE5. It doesn't happen on the local machine. I can open a terminal under KDE5 and the keyboard will function as expected... until I ssh into that box.

It doesn't happen if I boot into runlevel 3.

It doesn't happen if I boot into the other installation which has KDE4.

However, it does happen under XFCE on the installation which has KDE5... Which makes me think it might be related to one of the packages which was upgraded?

Anyone come across this problem?

Lately I've been wondering if we need to specify evdev as the driver for keyboards and mice in /etc/x11/xorg.conf. I'm currently playing with options parameters for a mouse. It took awhile but now /var/log/Xorg.0.log is cleaner and shorter and response is good. I'm trying to compare between two similar installs with different drivers spec'd but it is going to take awhile to assess function and "feel". If anything solid results I'll start a thread unless someone else has already researched this better. I'm just learning as I go and "trying stuff". I haven't attempted keyboard yet.

Thanks enorbet. You might be onto something. I'll take a look.
