  • glad i'm not the only one with e350 problems with DPM and UVD enabled.

    edit:
    fritsch one of the XBMC coders posted a patch to get uvd and dpm working together.

    Code:

    • I have tons of this error messages in dmesg, but everything seems fine

      HD7640G + HD7670M(closed through vgaswitcheroo), mesa and xf86-video-ati 20130706, llvm 3.4. kernel agd5f's drm-next-3.11 branch 20130705.
      Code:

      And when use mplayer and vdpauinfo, i got this message, but also seems harmless

        Yeah, this works, thanks.

        • black screen on 6740

          Hi,
          while an early try with drm-next-3.11-wip worked (but was slow-ish),
          latest drm-next-3.11 @f4dec318 gives a flash of garbled output
          then black screen, as soon as drm loads. Kernel crash.
          Nothing about the crash is logged on disk after reboot.
          PC is imac12,2, efi-booted.
