Subject: [Bug 71461] New: monitor doesn't get detected after boot
Date: Mon, 03 Mar 2014 08:06:27 +0000 [thread overview]
Message-ID: <bug-71461-2300@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=71461
Bug ID: 71461
Summary: monitor doesn't get detected after boot
Product: Drivers
Version: 2.5
Kernel Version: 3.13.5
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: tom.ty89@gmail.com
Regression: No
My card is Radeon HD5850.
The result might varies between different boot. Either the screens would not be
detected at all or they seem to be detected with a non-optimal resolution (in
console, while gdm shows a broken screen)
If a monitor is connected before boot, others can get detected correctly
afterwards.
If only one monitor is connected, turning it off can make the signal lost.
Reboot or suspend/resume (after turning it on again) can bring the signal back.
(Yet dpms would cause no problem at all)
The only way to reproduce the problem if DVI is involved is to disconnect it
physically, otherwise only powering off the monitor is required. My guess is
DVI detects display with a different mechanism.
