Dolphin fails to render using X w/o root rights (sudo dolphin displays a blank window)
Last modified: 2016-07-31 21:06:29 EDT
Description of problem:
When I try to launch dolphin under root, I get asked for password as normal, then the window shows, but the main pain is just blank/gray. I am using F22 with gnome desktop environment, so maybe it is issue related only for gnome users.
Version-Release number of selected component (if applicable):
Using: GNOME Shell 3.16.3
Steps to Reproduce:
1. $ sudo dolphin
1. $ su
2. $ dolphin
normal window displaying dolphin GUI
"QT_GRAPHICSSYSTEM=raster [kdesu|sudo] dolphin"
"QT_GRAPHICSSYSTEM=native [kdesu|sudo] dolphin"
It's more than just similar, it's the same one.
The workaround is the same, to run qt4 apps as root, set environment variable,
