No HDMI output from laptop

borffis · Oct 4, 2024

When I plug my Lenovo G51-35 running FreeBSD 11.3 into my TV's HDMI cable, the result is a blank screen. If I do likewise whilst running X, a caption displayed on the TV reads, "No signal." dmesg yields no messages pertaining to HDMI. Other laptops immediately convey a signal when plugged into the same hardware.
How can I troubleshoot this? Do I need to install a particular driver or edit any configuration?

You need something like this in the terminal:

Code:

xrandr --auto --output HDMI-1 --mode 1920x1080 --right-of eDP-1

Yes, for HDMI output you need to install a video driver. Which one depends on the hardware. To see display hardware:

Code:

% pciconf -lv | grep -B3 display

AMD, Intel: graphics/drm-kmod
nVIDIA: depending on the model

Official nVIDIA binary drivers:

x11/nvidia-driver-304
x11/nvidia-driver-390
x11/nvidia-driver-470
x11/nvidia-driver

Or FreeBSD port of Linux's nvidia-drm.ko Kernel module.
graphics/nvidia-drm-61-kmod
graphics/nvidia-drm-510-kmod
graphics/nvidia-drm-515-kmod

drm-kmod is installed, but I'm probably using the wrong driver. Thank you both so much!

borffis · Oct 7, 2024

To retract my prior assumption: I have no reason to believe that the driver from the kmod package that I've been using for the past 4 years is insufficient, but I may be wrong.

Anyway, xrandr prints this upon execution:

Code:

Screen 0: minimum 320 x 200, current 1366 x 768, maximum 16384 x 16384
eDP connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 173mm
   1366x768      59.97*+
   1280x720      59.97 
   1152x768      59.95 
   1024x768      59.95 
   800x600       59.96 
   848x480       59.94 
   720x480       59.94 
   640x480       59.94 
HDMI-0 connected 1280x720+0+0 (normal left inverted right x axis y axis) 16mm x 9mm
   1280x720      60.00*+
   1920x1080i    60.00 
   640x480       59.94

I tried:

Code:

xrandr --auto --output HDMI-0 --mode 1280x720 --right-of eDP-1
xrandr: cannot find output "eDP-1"

Then....

Code:

xrandr --auto --output HDMI-0 --mode 1280x720

and

Code:

xrandr --auto --output HDMI-0 --mode 1280x720 --right-of eDP

These execute without any errors returned, but I only see my graphics flicker onscreen momentarily every minute or two, distorted by pink/purple static.

Can anyone guess what's wrong with this....?

What kind of graphics is in that machine?
pciconf -lv | grep -B 4 VGA will tell you.

You might want to do something about that. 11.3 has been EOL for over four years.

This laptop's ethernet port has been shot for five.

Hmm, that is quite old. What does the Xorg log file (/var/log/Xorg.0.log) says about the driver it chooses?

Kindly excuse me if some of this is irrelevant; I am brainless layman who can't reliably discern pertinence....

To retract my prior assumption: I have no reason to believe that the driver from the kmod package that I've been using for the past 4 years is insufficient, but I may be wrong.

Anyway, xrandr prints this upon execution:

Code:

Screen 0: minimum 320 x 200, current 1366 x 768, maximum 16384 x 16384 eDP connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 173mm 1366x768 59.97*+ 1280x720 59.97 1152x768 59.95 1024x768 59.95 800x600 59.96 848x480 59.94 720x480 59.94 640x480 59.94 HDMI-0 connected 1280x720+0+0 (normal left inverted right x axis y axis) 16mm x 9mm 1280x720 60.00*+ 1920x1080i 60.00 640x480 59.94

I tried:

Code:

xrandr --auto --output HDMI-0 --mode 1280x720 --right-of eDP-1 xrandr: cannot find output "eDP-1"

Then....

Code:

xrandr --auto --output HDMI-0 --mode 1280x720

and

Code:

xrandr --auto --output HDMI-0 --mode 1280x720 --right-of eDP

These execute without any errors returned, but I only see my graphics flicker onscreen momentarily every minute or two, distorted by pink/purple static.

Can anyone guess what's wrong with this....?

Dear borffis:
your output device is eDP not eDP-1 ,so please change below command to try again..
xrandr --auto --output HDMI-0 --mode 1280x720 --right-of eDP (this is extend your eDP screen to HDMI-0)
xrandr --auto --output HDMI-0 --mode 1280x720 --same-as eDP (this is copy eDP image to HDMI-0)

maybe help you.

tingo · Oct 8, 2024

or try --mode 1920x1080i for HDMI-0.

tropicalbeast · Oct 23, 2024

One could also try to use a GUI to xrandr such as ARandR. It gives a drag-and-drop interface to setup the available screens and has the option of yielding a file containing the proper xrandr command used to create what's been done on the GUI.

Dear borffis:
your output device is eDP not eDP-1 ,so please change below command to try again..
xrandr --auto --output HDMI-0 --mode 1280x720 --right-of eDP (this is extend your eDP screen to HDMI-0)
xrandr --auto --output HDMI-0 --mode 1280x720 --same-as eDP (this is copy eDP image to HDMI-0)

maybe help you.

Again, these execute without errors but I can only see my output flashed to the screen every 3-4 minutes.

tingo said:
or try --mode 1920x1080i for HDMI-0.

This yields the same results.

I deeply appreciate all of the suggestions and support that I've received here. Maybe my laptop is defective. I dunno.
