#1872 Unable to start TexStudio

[Rohan Verma]

Hello,

I'm unable to start TexStudio. This is the output I get when I try to open it using

$ texstudio

My version is: TeXstudio 2.11.0 (6066+:2a9bee6257ec+)

[Jan Sundermeyer]

which OS are you using ?
What installation file did you use ?

[Rohan Verma]

I'm using Fedora and used DNF to install TexStudio.

[Jan Sundermeyer]

it seems to be a problem with Fedora's Qt5/GTK install. Nothing we can do about it ...

[Rohan Verma]

For anyone who lands here from search,

You can temporarily run textstudio with sudo.

[Pedro Mello]

this should do the trick without root:
QT_QPA_PLATFORMTHEME=gtk texstudio

+1 This works. Thanks :)
