HDMI issues with linux distros - Please Guide
 

Hi all,

I have a lenovo legion Y530 with a GeForce GTX 1050 board and I'm not beeing able to use an external monitor through HDMI port.

I've been reading lots of posts and wikis and the most descriptive one I've found is the following link
https://forums.lenovo.com/t5/Gaming-...e/td-p/4343696

I read a bout X windows System, Xorg, XRandR and other stuff, like, how to detect the hardware in the computer and stuff. But still I feel that there are some concepts that I have missing. Because is hard to me to understan how should I troubleshoot the HDMI port, how should I know if the port is ok or not? Can I send it a signal? How can I handle the video configurations?
I can not understand how to use the X11 config files, or Nvidia files and stuff.

Drivers are properly installed at its last version. Aparently the HDMI output is wired to the Nvidia GPU directly so if I want to use the Intel GPU, the HDMI is not going to work.

So, what actually I need from you people is help with guidance. I really want and need to understand how all this things work. I don care if you post and answer with a link about how to turn on a computer, I'm going to read it. But I really would like to learn how to glue all this things together and be able to handle this kind of situations.

I hope you can understand me and be able to help through.

Regards

I don't really have your answers. I was reading someone struggling with nvidia drives. Turned out there's something with 2 video gpu with the intel processor, like yours.

Here's part of it, if it gives you a clue, http://forums.debian.net/viewtopic.p...art=15#p705660

it seems similar to your link. bumble-bee, nvidia configured xorg.conf and lots of tweaking. There's a chance you'll get more detailed information.

It sounds like you need to write yourself a nn-video.conf in /etc/X11/Xorg.conf.d. I did one for this laptop when I was connecting odd stuff at different times. You'll find examples online.; Man xorg.conf is your friend. You need to use

• A "Server_Layout" section to map out video -->device -->monitor. This is how the system is supposed to work.
• A description of each monitor that you hook up. If there's 5 different monitors, X will ignore tho others.
• A "Device" section telling what video card is driving it.
• A "Screen" section with the details of each output.

Otherwise will default to what is considered 'normal' and that doesn't obviously suit you.

I had "fought" with nvidia in the past, I used nvidia-xconf (or similarly named) copy 'n pasted the parts specific to nvidia I needed and saved to /usr/share/X11/xorg.conf.d as something like 60-nvidia.conf

Thanks business_kid I'm going to try that work arround, I think is going to take me some time, I don't have as much free time as I like and I'm not that experienced in xorg configs in order to fill the file up and go.
As soon a as I can try that conf I'll let you know.

Thanks for the tips !

Er, let me correct myself; A Device section per output. When I did it, I had a vga plug with whatever on it, a laptop screen with 1600×900, and a hdmi output with hdmi or 1280×720 on it. I had 3 device sections, which may not all have been needed, but I think they were.

Intel GPU + NVidia GPU in a laptop is spelled Optimus. Optimal Optimus configuration requires for most users inclusion of Bumblebee or Prime or Xrun software in addition to normal or NVidia drivers. Optimus is a headache creator for many of, probably most of, its Linux users. Archlinux's wiki is probably the best place to grasp how to work the glue with Optimus.
