--- Comment #18 from chriskoch@goldmail.de --- A short update: In the meantime I am adding the modeline for my monitor manualy. The automated solution is a 10-monitor.conf like in this thread: https://archived.forum.manjaro.org/t/stuck-at-low-display-resolution/115976 This works until Kernel 5.8. With Kernel >= 5.9 my monitor doesn't accept the modeline anymore. Since this problem has been reported 2 years ago and nothing happened, I am wondering if it will ever be fixed. Let me know how I can follow up/contribute to fix this.
