Subject: [Bug 39683] New: radeon "hd6770 flex" dpms fails to unblank one display sometimes
Date: Sat, 30 Jul 2011 02:33:17 -0700 (PDT) [thread overview]
Message-ID: <bug-39683-502@http.bugs.freedesktop.org/> (raw)
https://bugs.freedesktop.org/show_bug.cgi?id=39683
Summary: radeon "hd6770 flex" dpms fails to unblank one display
sometimes
Product: DRI
Version: XOrg CVS
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: chainsawbike@gmail.com
when "dpms off" is triggered ( by timeout, xset ) both displays turn off but
only one display turns back on, if i do `xset dpms force off` after then both
displays turn back on as expected
the standby and suspend states also seem to behave in the same way but i only
briefly checked
there seems to also be some timing factor as the second time seems to need to
be triggered soon after the first for both displays to turn back on
the display affected is labeled as"DisplayPort-1" but is infact a dvi plug
(note this a "flex" model, allowing 3 dvi displays out of the box so it may be
a bit different to a standard one ...dunno)
the only interesting thing i could find in the logs:
dmesg:
[drm:radeon_dp_get_link_status] *ERROR* displayport link status failed
[drm:radeon_dp_link_train_cr] *ERROR* clock recovery failed
(once - part way through the repeats of the following message)
[drm] force priority to high
(repeated - about the amount i would expect if it was repeated once per failed
attempt)
