it’s not installed by default it’s in the Mesa-demo-x package
zypper in Mesa-demo-x
sudo glxinfo
you could also try lspci (which does not have as detailed report)
sudo lspci | grep VGA
if that is not an optimus laptop (hybrid intel+nvidia) you should disable the intel gpu in bios (set pci-express as the preferred gpu)
if that’s an optimus laptop you need to use bumblebee

Well, but Xorg does seem to detect an intel GPU, it loads a driver for it.
From your log:

intel is not installed, so it falls back to “modesetting”:

Can you please post the full output of lspci?
And again, the output of “glxinfo” please to see whether OpenGL support is working.
As I_A wrote (and I did earlier already as well), it’s in the package Mesa-demo-x.
Alternatively you could post the information from kinfocenter’s OpenGL module.
Also, what exact nvidia packages do you have installed?
rpm -qa | grep nvidia
The Leap 42.x packages probably won’t work properly on Leap 15.0 (regarding OpenGL) because of the new libglvnd.
I disabled inner GPU in BIOS. And had new special Linux loading. Is it good for optimal performance and resources consumption to disable it?
My Mesa* packets are still installed.

Sure, it definitely frees some resources. Power consumption should be lower at least, although the difference probably won’t be much.
But in particular, it should avoid loading the intel kernel module and X driver, which may have caused problems.
My Mesa* packets are still installed.
Yes, that’s fine.

Not so relevant anymore after you disabled the intel GPU… 
rpm -qa | grep nvidia **nvidia**-computeG04-390.67-lp150.8.1.x86_64 **nvidia**-gfxG04-kmp-default-390.67_k4.12.14_lp150.11-lp150.8.1.x86_64 x11-video-**nvidia**G04-390.67-lp150.8.1.x86_64 **nvidia**-glG04-390.67-lp150.8.1.x86_64
Ok, looks fine, and the glxinfo output as well.
So, is dolphin still crashing after you disabled the intel GPU?
yes, like other apps
Well, try to delete the folder ~/.cache/ then, maybe it helps.
Also see whether the problem occurs on a fresh user account as well.-
I tried it before on 2 new accounts
Ah right, I haven’t read everything at the beginning of this thread, sorry.
Would it work to run them as root? (e.g. “kdesu dolphin”)
What about a different desktop? (IceWM should be installed by default in any case, choose that at the login screen)
I had another look at your backtrace, and it’s actually a “Bus error”, which is not a “normal” crash that would point to a bug in the application (that includes KF5/Qt5), but usually indicates a problem on a lower level…
You say that it started after some update.
Maybe try to boot the previous kernel as a test (“Advanced Options” in the boot menu)
Otherwise you could revert all updates (e.g. by disabling the update repo and running “zypper dup”), see if it works then, and then install updates one by one to find out which one breaks things. (if you remember when it started exactly, you could also take a look at the zypper log or YaST’s history to find possible culprits and only revert those via the “Versions” tab in YaST e.g.)
Another thing I would try is uninstall the nvidia driver completely and see if it works then.
Reinstall it afterwards; if it is a problem with the nvidia installation that might actually even fix it… Although I somehow doubt it as the glxinfo output looks fine.
Actually, I find it strange that the problem would affect all(?) Qt5/KF5 applications, but not Plasma5 itself anyway (and other desktop services like kwin the window manager). Or do I misunderstand something?
Try reinstalling kde
sudo zypper in -D '*kde*'
I did not read from the beginning, but you tried to delete the configuration files in the hidden files
sudo kdesu dolphin
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.
Plasma bottom panel often freeze it icons/applets after launching some apps.
1)Maybe not only KDE.
2)tried with a new user
Omit the sudo, just run “kdesu dolphin”.
kdesu switches to root anyway, that’s its purpose, it’s a GUI-based sudo replacement.
And sudo cannot run graphical applications in openSUSE.
Another thing to try may be to disable apparmor as a test, it might interfere in unexpected ways (in case of too strict profiles) and that would even affect root.
sudo systemctl stop apparmor
I made an update from a USB drive with removing external (Pacman etc) repos. Dolphin launches for 1 sec then crashes.

yes. Second user has a permanent crash. Current user has a 1-second liveable Dolphin window with empty navigator tabs.
