XCB error: 148 - Qt application display issues
-
i was also facing the same issue
the solution that worked for me was,
coping my libxcb.so file on the system i am running my application and making a any_name.conf file in /etc/ld.so.conf/any_name.conf with the folder path where libxcb is placed.i have placed my libxcb.so in "platforms" folder where my application is.
hope this helps...

Hi and welcome to devnet,
What are the differences between both machines ?
And how did you deploy your application ?@Swapnil_Shelke modifying the ld.so.conf configuration of a user machine for a library that is likely already installed on that machine is not a good idea.

Comp1 (working) -
Nvidia GTX 960
ubuntu 14.04
Qt 5.7Comp2 (error) -
Nvidia GTX 1050
ubuntu 16.04
Qt 5.7I compiled my code on comp1, and just took the executable. Linking is dynamic to the Qt libraries (they came from the same installation file).

Where does the Qt you installed come from ?
Just to be sure, you only copy the executable to your other machine ?

The Qt comes from Qt's site, I've installed using the 'qt-opensource-linux-x64-5.7.0.run' script.
And yes, just copied.

Then are you sue that you are using that version of Qt when running your application ?

I'm sure. Will try to reinstall Qt and run it again. Do you have any direction I can look into to even figure out what this error means? -
You didn't deploy the application, did you ? You just copied the executable over you other machine ?

Hi
Normally you create a deployment folder containing
a few subfolders ( like platforms )
and the needed dlls/so files.http://www.tripleboot.org/?p=138
http://doc.qt.io/qt-5/linux-deployment.htmlYou can also test this app
https://github.com/probonopd/linuxdeployqt
(i have not tried it yet)To inform the loader on linux about the so files in the folder, you can use rpath.
