QtCreator will not start up, no crash report, no window.
-
I installed Linux as my main Platform or OS. This is a virgin install of Ubuntu 21.04 x86_64. Nothing extra has been added to the OS installation, except Qt & QtCreator. The online installer program works fine here. I tried starting starting various Qt apps such as qtcreator, none would start up, some gave crash reports and others didn't.

Hi,
Start Qt Creator from the command line with the QT_ENVIRONMENT_VARIABLE set to 1 to see exactly what is going on.
You are likely missing some Xorg related libraries.

I believe Ubuntu 21 has wayland as default platform plugin. Try
export QT_QPA_PLATFORM=wayland
to see if it helps.on X11 systems:
$ echo $XDG_SESSION_TYPE
x11on some wayland system:
$ echo $XDG_SESSION_TYPE

@JoeCFD said in QtCreator will not start up, no crash report, no window.:
export QT_QPA_PLATFORM=wayland
Here's a screenshot of what I tried last. I am sorry it took so long to answer. I was in the hospital with pneumonia and it was double pneumonia that turned septic and I almost went into septic shock. -
I did something about the way I login to Ubuntu. I changed from wayland to x11 display and qtcreator started up normal.
