Created attachment 24521 [details] multi-seat Xorg configuration file I have two radeonhd cards: primary (integrated rs780) and secondary (rv710). I can get both cards working in the same time with the single Xserver configuration, but when i use multiseat configuration (each card have their own Xserver) the secondary card is failing to initialize. From the corresponding Xorg.log file i see: (--) RADEONHD(0): Detected an RV710 on an unidentified card (II) RADEONHD(0): Mapped IO @ 0xfe7f0000 to 0x7fc05337f000 (size 0x00010000) (II) RADEONHD(0): PCIE Card Detected (II) RADEONHD(0): Getting BIOS copy from legacy VBIOS location (II) RADEONHD(0): ATOM BIOS Rom: SubsystemVendorID: 0x1002 SubsystemID: 0x1002 IOBaseAddress: 0xb000 Filename: M3A78T_D_1.b BIOS Bootup Message: B27722 RS780D DDR2 200e/500m i.e. radeonhd use atombios of primary vidocard for secondary one and later we get: Backtrace: 0: /usr/local/bin/X1(xf86SigHandler+0x6a) [0x47898a] 1: /lib/libc.so.6 [0x7fc0518e5190] 2: /usr/lib/xorg/modules/drivers//radeonhd_drv.so(RHDAudioUnregisterHdmi+0x4d) [0x7fc04fe243ed] 3: /usr/lib/xorg/modules/drivers//radeonhd_drv.so(RHDHdmiDestroy+0x42) [0x7fc04fe3ae92] 4: /usr/lib/xorg/modules/drivers//radeonhd_drv.so [0x7fc04fe229b2] 5: /usr/lib/xorg/modules/drivers//radeonhd_drv.so(RHDOutputsDestroy+0x5c) [0x7fc04fe4a12c] 6: /usr/lib/xorg/modules/drivers//radeonhd_drv.so [0x7fc04fe35762] 7: /usr/lib/xorg/modules/drivers//radeonhd_drv.so [0x7fc04fe37c2e] 8: /usr/local/bin/X1(InitOutput+0x9eb) [0x46b29b] 9: /usr/local/bin/X1(main+0x2c6) [0x4369f6] 10: /lib/libc.so.6(__libc_start_main+0xe6) [0x7fc0518d15a6] 11: /usr/local/bin/X1 [0x435e99] Fatal server error: Caught signal 11.

I can confirm this behaviour, with the following cards VGA compatible controller: ATI Technologies Inc Radeon HD 3870 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3450
I think Egbert has some ideas about secondary card posting - this issue seems to be related (though not equal).
Does this issue occur with the preferred ati driver (xf86-vide-ati)? If so, please move this to the Driver/Radeon component. Development of radeonhd has pretty much halted and development focus is on the ati driver. Please see http://www.x.org/wiki/radeonhd If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.
the bug does not exist anymore, thanks!
