Summary: radeon/KMS: Screen hotplugging does not work any more
Product: DRI
Version: DRI 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: direx@betriebsdirektor.de
I noticed that in recent kernel versions the runtime detection of newly added
monitors does not work properly.
When I plug in my TV (DVI2HDMI) after booting I cannot enable it. xrandr
correctly shows a new screen and I can even enable the output, but the TV
screen stays black. Restarting X does not help.
The driver also seems to recognize the port status after plugging it in
(/sys/class/drm/card0-DVI-I-2/status) changes from "disconnected" to
"connected".
When I plug the HDMI cable in _before_ booting my computer the TV works just
fine.
GFX: Radeon HD 3870
Linux: 2.6-git (issue appeared in 2.6.35) with KMS
Mesa: git
libdrm: git
xf86-video-ati: git

What was the last kernel version where this worked? Is the issue still present
in 2.6.36rc3? Can you attach your dmesg output and xorg log?

I remember that this worked just fine in 2.6.34. The problem was introduced in
an early RC of 2.6.35 and is still present in 2.6.36-rc3.

Any chance you could bisect it?

I just experiented a bit and it didn't work with 2.6.34.6 neither with
2.6.33.7. This is why I assume that screen hotplugging never worked with KMS on
my R600 - I must have confused it with fglrx which I was also using until now.
And I forgot to say something about the logs I did attach yesterday: the logs
are from a system which booted without a second screen attached. After the
XSession loaded I plugged in the monitor and enabled it with xrandr.
