Priority: medium Bug ID: 64850 Assignee: dri-devel@lists.freedesktop.org Summary: Second screen black on Pitcairn PRO Severity: normal Classification: Unclassified OS: Linux (All) Reporter: flocke@shadowice.org Hardware: Other Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI

Created attachment 79637 --> https://bugs.freedesktop.org/attachment.cgi?id=79637&action=edit dmesg | grep drm right after boot (no X11)

I just installed my new Pitcairn PRO card (Radeon 7850) in my PC.

Every time I boot into linux (Arch Linux x86_64) my second monitor turns black right at boot. There are no errors and I can even start X11 with my dual-monitor configuration and move the mouse from my first screen to the right. It is as if the screen is there, only my monitor doesn't show it.

This happens not in X11, in fact the secend screen goes black as soon as the kernel/kms is loaded.

I attached the output of 'dmesg | grep drm' with the drm.debug=15 kernel option right after booting and befor starting X11 and I will attach the same commands output after running X11.

--- Comment #2 from Jakob Nixdorf flocke@shadowice.org --- Forgot some information, as always ;)

I tried it with a self-build kernel 3.10-rc2 and the Arch Linux stock 3.9.3, both with the same result. Will try some older kernels soon.

--- Comment #3 from Jakob Nixdorf flocke@shadowice.org --- Update:

I tested the Arch Linux kernels 3.9.2 and 3.8.11 with the same result.

And, in case it is important, I noticed this line in dmesg:

[ 3.169540] radeon 0000:01:00.0: Invalid ROM contents

I hope this can help further.

--- Comment #6 from Jakob Nixdorf flocke@shadowice.org --- I will upload my xorg log as soon as possible. But I think its a DRM or KMS issue, since it already happens before I start X (no TTY on the second screen at boot after KMS starts).

And no, its not the HDMI screen, its the one connected via DVI.

--- Comment #9 from Jakob Nixdorf flocke@shadowice.org --- Ok, i tested a few things:

Turning the monitor off/on dosen't do anything, its still black.

Using xrandr to change the mode causes the first monitor to also turn black, I will upload the output of "dmesg | grep drm" after the xrandr command, Xorg.0.log doesn't say anything new.

The output of the xrandr command itself (with --verbose) is:

crtc 1: disable screen 0: 2960x1050 780x277 mm 96.28dpi crtc 1: 1280x1024 75.0 +1680+0 "DVI-0"

sorry, I meant using xrandr; e.g.,

xrandr --output DVI-0 --off xrandr --output DVI-0 --auto

--- Comment #12 from Alex Deucher agd5f@yahoo.com --- Can you also try booting with only one monitor connected? Does the DVI monitor work in that case? Also try booting with one monitor connected and then add the second one after X is started and see if both are enabled properly in that case.

--- Comment #14 from Jakob Nixdorf flocke@shadowice.org --- 'xrandr --output DVI-0 --off' causes the first screen (HDMI-0) to turn black too, and the DVI screen gets really switched off (monitor switches to standby).

Blind-typing 'xrandr --output DVI-0 --auto' turns the DVI screen back on (still only a black screen) and the HDMI screen also stays black.

--- Comment #15 from Jakob Nixdorf flocke@shadowice.org --- Nothing of the things you suggested worked.

Without xorg.conf the problem is still present.

Booting with only DVI-0 plugged in works fine. If I plug in HDMI-0 with X11 running everything stays the same and the HDMI monitor says "No signal", when I try to activate it via xrandr both monitors switch to black. If I plug in HDMI-0 in TTY the TTY is switched to the HDMI monitor and the DVI monitor goes black.

--- Comment #16 from Jakob Nixdorf flocke@shadowice.org --- I checkt again when the second monitor is switched off.

I booted with radeon.modeset=0, which caused the radeon module to not be loaded since I don't have UMS support in my kernel. With this both monitors work and I can get a TTY on both. But as soon as I run 'modprobe -v radeon modeset=1' the second monitor is switched off to black.

--- Comment #17 from Jakob Nixdorf flocke@shadowice.org --- Created attachment 79737 --> https://bugs.freedesktop.org/attachment.cgi?id=79737&action=edit ROM Dump

I played around some more. I compiled my kernel with UMS enabled and booted with 'radeon.modeset=0' which resultet in the 'radeon' module beeing loaded successful and without the 'Invalid ROM contents' error. Also both screens are active in the TTY. After running 'rmmod radeon && modprobe -v radeon modeset=1' the DVI-0 screen goes black again and the TTY is only shown on HDMI-0. Also the 'Invalid ROM contents' error shows up again.

Additionally I made a dump of the ROM ('echo 1 > /sys/bus/pci/devices/0000:01:00.0/rom && cat /sys/bus/pci/devices/0000:01:00.0/rom > rom-dump'), because this error somehow bugs me ;) maybe it can help.

--- Comment #18 from Jakob Nixdorf flocke@shadowice.org --- New update: It seems to have nothing to do with the connectors that are used. I just got my mini-DisplayPort to DVI adapter and tested it. No combination works (HDMI+mDP, DVI+mDP, HDMI+DVI) the second screen is always black.

--- Comment #19 from akb825@gmail.com --- I have a Radeon 7870 and I have the same problem: the desktop extends as if there are 2 monitors, but the second monitor is always black. I have both monitors plugged into DVI ports (DVI-0 and DVI-1), and xrandr correctly recognizes both monitors as being present as well as all of their display modes, but whenever I try to change the display to one monitor or the other it will only ever display on the monitor plugged into DVI-0.

When I go through the display settings tool in XFCE (which I'm assuming is just a UI around xrandr) it correctly shows both monitors, but whenever I try to adjust the second monitor's resolution or disable the second monitor it completely corrupts the display (showing a striped pattern on the first monitor, second monitor is still black) and the only way to recover is to reboot. I can switch to a tty terminal and blindly type commands, but when I attempted to shut down my display manager daemon and unload the radeon module nothing happened, though since the display was corrupted I couldn't see if either of the commands failed. Adjusting the resolution of the first monitor works correctly.

One thing to note is whenever I start xorg, the following gets printed several times to the error log: May 29 20:27:31 localhost kernel: [ 199.484959] radeon 0000:02:00.0: bo ffff8801ad899400 don't has a mapping in vm ffff8801affc6980

I am also using 64-bit Arch Linux, running under kernel 3.9.4 and xorg 1.14.1.
