Priority: medium
Bug ID: 72648
Assignee: dri-devel at lists.freedesktop.org
Summary: All 3 monitor EDIDs show the same
Severity: normal
Classification: Unclassified
OS: All
Reporter: jim.cromie at gmail.com
Hardware: Other
Status: NEW
Version: XOrg CVS
Component: DRM/Radeon
Product: DRI
I recently bought a 3rd monitor, plugged it to my radeon,
turns out its EDID is bad; it caused 2 of 3 monitors
to go to low-res, which Id reboot to correct (ick)
I fixed that with
drm_kms_helper.edid_firmware=VGA-1:edid/1920x1080.bin
.. which is nice, esp as its been available since 2012 :-)
what worries me is the following:
I have 3 different monitors on the 3 video connectors,
and dmesg (pasted below) confirms this.
