Priority: medium Bug ID: 77835 Assignee: dri-devel@lists.freedesktop.org Summary: X crash when using xrandr with R9 290X and 7870 for triple head Severity: major Classification: Unclassified OS: Linux (All) Reporter: mbroemme@libmpq.org Hardware: x86-64 (AMD64) Status: NEW Version: unspecified Component: DRM/Radeon Product: DRI
Created attachment 97831 --> https://bugs.freedesktop.org/attachment.cgi?id=97831&action=edit Xorg log of crash
I'm trying to get a system with a R9 290X and a HD 7870 GHz Edition working. If I use the cards independently everything works fine under X (the 7870 works with glamor acceleration and the R9 290X without acceleration) but the problem is to get them working together with single X. Attached is my Xorg.0.log and the dmesg output. I'm using the following cards:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii XT [Radeon HD 8970] 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn XT [Radeon HD 7870 GHz Edition]
Steps to reproduce this issue:
#1 startx #2 xrandr --output DVI-0 --primary #3 xrandr --output HDMI-1 --right-of DVI-0 #4 xrandr --setprovideroutputsource 1 0 #5 xrandr --output HDMI-1-0 --mode 1920x1080 --right-of HDMI-1
Right now X is crashed with the following:
(EE) (EE) Backtrace: (EE) 0: /usr/bin/X (xorg_backtrace+0x48) [0x584b08] (EE) 1: /usr/bin/X (0x400000+0x1887f9) [0x5887f9] (EE) 2: /usr/lib/libpthread.so.0 (0x7f2a182c8000+0xf880) [0x7f2a182d7880] (EE) (EE) Segmentation fault at address 0x0 (EE) Fatal server error: (EE) Caught signal 11 (Segmentation fault). Server aborting (EE) (EE) Please consult the The X.Org Foundation support at http://wiki.x.org for help. (EE) Please also check the log file at "/var/log/Xorg.0.log" for additional information. (EE) (II) AIGLX: Suspending AIGLX clients for VT switch (EE) Server terminated with error (1). Closing log file. XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0" after 4790 requests (4790 known processed) with 9 events remaining. xinit: connection to X server lost
The system is running Arch Linux with the following configuration:
ati-dri 10.1.1 glamor-egl 0.6.0 libdrm 2.4.53 linux 3.14.1 linux-firmware 20140316.dec41bc mesa 10.1.1 mesa-libgl 10.1.1 xf86-video-ati 7.3.0 xorg-server 1.15.1
Does anybody has a hint what I could try next? Also what is needed to get acceleration working. I tried it with "NoAccel" "False" and "AccelMethod" "glamor" but it just freezes my X on startup. :)
