Böyle bir hata veriyor burada diyorki root ile açma user ile aç diyo :d başa döndük işte o yüzden kde gri ekran problmini aşmam gerek.
VLC is not supposed to be run as root. Sorry.
If you need to use real-time priorities and/or privileged TCP ports
you can use vlc-wrapper (make sure it is Set-UID root first and
cannot be run by non-trusted users first).
