Xhost ile Eri\u015fim Kontrol\u00fcn\u00fc Ayarlay\u0131n<\/h2>\n

Bazen grafiksel uygulamalar\u0131 \u00e7al\u0131\u015ft\u0131r\u0131rken eri\u015fim izinleriyle ilgili sorunlar olabilir, bu durumda xhost<\/strong> komutunu kullanarak X sunucusunun eri\u015fim kontrol\u00fcn\u00fc ayarlamak m\u00fcmk\u00fcnd\u00fcr.
