I have the same problem here. HP nc6400 (Notebook)
switched off DDC xrandr lists only 60Hz (as I have force-configured it in xorg.conf) 1280x1024 gives 85Hz which my LCD (borked DDC-Infos from there) reports being capable but causes it to flicker that I am in fear the monitor wears out ... 800x600, 1024x768, 1600x1200 all give 60Hz and the image is stable. My settings in xorg.conf are ignored. ** Attachment added: "xorg.conf - do not even ask me about dual monitors ..." http://librarian.launchpad.net/4976075/xorg.conf -- Unable to adjust refresh rate.. https://launchpad.net/bugs/50048 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
