...> modes? Another quick glance at the specs leads me to believe c858cfcae6d is correct. 8-15 does say that a sink supporting 3D must at lesst support one of the modes listed in that table. But that's just the very start of the story and we are really talking about the 3D_present bit in the HMDI VSDB and the associated "mandatory" modes (the term comes from the spec). HDMI 1.4a Page 155: "3D_present [1bit] This bit indicates 3D support by the HDMI Sink, including the mandatory formats. If set (=1), an HDMI Sink supports the 3D video formats that are mandatory formats,&quot...

My main testing device was a Samsung TV with this 3D_present bit set and all the advertised modes were working. Can't quite remember if that included the interleaved mode. -- Damien

...articular compare the mandatory modes to the other modes advertised by that TV. Maybe we could see some kind of pattern emerge, like the 3D modes supported being the ones with the timings in table 8-15. -- Damien [1] https://cgit.freedesktop.org/xorg/app/edid-decode/ data/samsung-UE40D8000YU-hmdi

...mention nouveau anymore, success? No, it still hangs w/ ml kernel. ==== After all this, I wanted to get back to kernel 3.10, to see now that nouveau is off, if that changes something. Well this is a surprise, everything works fine w/ this 3.10.0-514.26.2.el7.x86_64 kernel (suspend/hibernate/wifi/hmdi-out/dell keys/vmware) BUT the bluetooth (and the dell fn+radioswitch key). I re-installed drv-nouveau, removed the blacklist file from /etc/modprobe.d and all is still OK, but Xorg doesn't loads nouveau driver despite the fact that lsmod shows the nouveau kernel module (I checked, during my fo...

Ok you in Grub press tab and then add ?3? after the initrd entry ?. quiet?? yum remove xorg-x11-drv-nouveau And see if X11 come up with standard frambuffer? Disable nouveau complete from kernel if the upper not helps. nano /etc/modprobe.d/blacklist-nouveau.conf blacklist nouveau > Am 04.08.2017 um 12:52 schrieb wwp <subscript at free.fr>: > > Hello, > > > On Thu,
