How depressing. It's been 10 years I've been using linux and STILL there's massive problems detecting EDID of monitors. Stuck with 800x600 on my 23" Samsung. Guess I'll have to manually write my Xorg.conf but really, 10 years and still this shit ?
Interesting. Reboot and suddenly it can find the EDID and works fine.
10 years and you have only just rebooted?
