QApplication: invalid style override passed, ignoring it.

so it seems that reinstalling libxcb fixed the issue. So thank you very much guys.
I own you really big beer :-)

@SGaist
there is no such thing on manjaro or archlinux which manjaro is baseed on

DevAlone

For those who could face the same issue and didn't solve by reinstalling libxcb: in my case the message was the same but it was caused by apps inside lxc unabling to open display, so, try to run another GUI app like xclock.

rrd0

@DevAlone

qt.qpa.xcb: could not connect to display <<-- Is that the message you're talking about?

Could you explain a little better what was your problem and how did you fix it?

What is lxc? And why to run another GUI app? I really didn't understand what you did to fix this problem.

jcren

@twar
Hi, twar!
I met the same error as yours, and I cannot solve it after using several methods.
Can you tell me how to fix it more clearly? I'm new to geant4, so I cannot understand what you have said.
Thank you!

Best Wishes,
jcren.

Hi

NyilasLaszlo

Hi for all!
I downloaded and extracted XnView MP version 0.96 on Arch Linux and same error happened.

Solution:
I am deleted these two files: libfreetype.so and libfreetype.so.6 .

Hi,

Start your application with the QT_DEBUG_PLUGINS environment variable set to 1 to get more information.

Srinivas Reddy

I am using Qt-5.15.0, got the same problem.
More details are:
QLibraryPrivate::loadPlugin failed on "/opt/Qt/5.15.0/gcc_64/plugins/platforms/libqxcb.so" : "Cannot load library /opt/Qt/5.15.0/gcc_64/plugins/platforms/libqxcb.so: (libxcb-xinerama.so.0: cannot open shared object file: No such file or directory)"

Solved by installing the dependent package.
Command to install: sudo apt-get install libxcb-xinerama0

JamieC

Fresh install had the same issues reported here. Did what @Srinivas-Reddy suggested and install libxcb-xinerama0 and everything started working. Thanks!

PabloC

@JamieC I had the same problem, install libxcb-xinerama0 and I solved it, Thanks!

Advig

Tried reinstalling libxcb and worked for me as well.

inbdz

@Srinivas-Reddy many thanks

Lengendary

Thanks very much!
I spent several hours trying to solve this problem until I got here.
sudo apt-get install libxcb-xinerama0
Thanks!

@Lengendary Thank you!

What could be the issue? Please suggest.
Please let me know if you need to know anything else for this.

Hey @SGaist , Can you please suggest anything for this?

SGaist

@singhravi run ldd on the plugin itself.

singhravi

@SGaist Thanks a lot for the reply!
Do you mean this? ldd ~/Qt/5.12.9/gcc_64/plugins/platforms/libqxcb.so
If yes, then I've included its output in the original comment.
Please let me know if this is not what you mean.

SGaist

I missed that line.

I see that you have that issue with an AppImage, does it also happen with just your binary ?
