Description Bug 2007-09-28 03:17:19 UTC

1280x960 isn't detected in EDID and not shown in xrandr

It used to be a valid mode with the old driver.

Option "IgnoreEDID" "1"
Option "DDCMode" "0"
Are completely ignored.

As are manually specified Modelines in the monitor section.

Well, it's an arbitrary mode.  Should we add all arbitrary modes?  I think not.  By default we make available the edid modes and/or vesa modes.  Manually adding modes will work with any output as long as it's supported by the monitor.

Could this be related to https://bugs.freedesktop.org/show_bug.cgi?id=12626

Comment 9 Alex Deucher 2008-12-03 00:24:50 UTC

you can manually add modes with xrandr or via your config.  see this page for more:
