If X runs as root, then /var/log/Xorg.0.log If X runs as you, then ~/.local/share/xorg/Xorg.0.log Which way X runs depends on how you start X *and* on which graphics chipset is being used. (Some chipsets require the legacy X-as-root.)

What does Xorg.0.log say? Share the whole thing via paste.debian.net (optionally pastebinit via cmdline). I suspect you're going to need specialized help due to some bug. Where to go I can't be sure, because nothing you've written makes it completely unambiguous whether the HDMI port is controlled by a proprietary NVidia driver or one of the FOSS drivers. https://support.hp.com/us-en/document/c05567143 doesn't seem to help either. If it's only NVidia showing up in the log, you probably need to goto NVidia's support forum. If Intel is showing up in the log, then I'd start with the intel-...@lists.freedesktop.org mailing list so that Intel's driver devs can take a look. For the latter, https://01.org/linuxgraphics/documentation/how-report-bugs has rather explicit instructions to consider. -- "The wise are known for their understanding, and pleasant words are persuasive."

With a little more research, I have found that the HDMI interface is detected and shows up on the xrandr output. However, it shows up as being disconnected, even though it is indeed connected. I note that I have checked both the cable and the the connector on the monitor (HDTV in this case) and they both are good -- both windows on the same laptop, and the HDMI outputs of two different Android tablets work with the TV on their HDMI ports using the same cable and input on the TV. I have done a little additional research on the web, and found a couple of similar situations, but I have been unable to get xrandr to show the HDMI port as connected. -- 73s de Mike, WB5VQX

Check out this link, and installed the proprietary NVIDIA driver along with Bumblebee. This solved another problem when the NVIDIA driver was installed which caused GDM to crash on boot. However, this did not solve the issue with the HDMI output. I still show only the main display in gnome-control-center, no HDMI display. I suspect, therefore, that the problem is with the other VGA device showing on lspci: VGA compatible controller [0300]: Intel Corporation Device [8086:591b] (rev 04) which shows as "Intel Kabylake HD Graphics GT2" in /sys/bus/devices/:00:02.0/label > > These should be useful even though not intended for Debian: > https://wiki.archlinux.org/index.php/PRIME > https://wiki.archlinux.org/index.php/NVIDIA_Optimus Note that there does not appear to be an Intel Optimus device on the system, the NVIDIA card if an Intel GeForce GTX. -- 73s de Mike, WB5VQX

Sounds to me like your key search terms should have been 'linux hybrid graphics' or 'debian hybrid graphics', and you don't have any of the possible candidates installed. https://wiki.debian.org/Bumblebee looks like a place to start.

Missing HDMI display
Ok, guys. I'm working on getting Debian 9.1 with Gnome DEfully functional with a new laptop. A couple of the issues have been addressed already, and fixed. The next issue is a missing HDMI output. I'm running a very new HP Pavilion Power laptop (model number 15- cb045wm with core i7-7700 CPU, Intel Kabylake HD Graphics GT2, and NVIDIA GeForce GTX 1050 GPU. The laptop has an HDMI connector on the side, and it works with Windows 10. However, the HDMI display does not show up under linux. The HDMI output does show up under Pulseaudio, though it appears to be non-functional, i.e., when I set the configuration up for HDMI output, nothing comes out through the HDMI connection. I have no real idea how to troubleshoot this issue, and suspect that this system may be new enough that the drivers have not caught up with the chipset, and so I may be out of luck for a little while. I have searched the debian-user list archive and found nothing that appeared to be useful. Any information one of you Gurus might have will be appreciated. Thanks in advance. -- 73s de Mike, WB5VQX
