Hello,

I'm a beginner and this is my first Linux based os. It's all very new for me.
I made a fresh installation this week and now I tried to install brave browser. I used zypper. Then I want to start up the browser but nothing is happening, except that I see a window opening and closing in the bar under. I thought it may be some issue with brave browser, untill now. I tried to install Vivaldi browser (I don't like Firefox), again with zypper. Now, the same is happening. So, the problem must be somewhere else.

Any idea what is going on and how I can solve this?

greetings
