Re: Lenovo IdeaPad S340-15IWL Won't recognize external monitors

IdanWolnnec,

If you want to pursue this problem, this procedure possibly could give some additional info. Download Mint 18.3, install to a USB and run a live session with the monitor connected. If the monitor is working, then get the output of ls /sys/class/drm and xrandr --verbose

Re: Lenovo IdeaPad S340-15IWL Won't recognize external monitors

IdanWolnnec,

Would you test this parameter on the kernel command line, like I previously instructed in my second post:

Code: Select all

video=HDMI-A-1:e drm_kms_helper.edid_firmware=HDMI-A-1:edid/1920x1080.bin

Re: Lenovo IdeaPad S340-15IWL Won't recognize external monitors

Was that xrandr output from the old laptop? It doesn’t show the HDMI port (DP-1) connected either

If the monitor does work on the old laptop, then get the output of xrandr --verbose and inxi -SGx

Re: Lenovo IdeaPad S340-15IWL Won't recognize external monitors

DP-1 comes from the ls /sys/class/drm output, which is how the kernel graphics driver named the HDMI port. Ask the Linux developers why this confusing naming system is still used: card0 card0-DP-1 card0-eDP-1 renderD128 version Getting monitors connected to laptops working is a common Linux problem....

Re: Acer XB280HK HDMI External Monitor Connected to Acer Nitro V Laptop Showing as "Disconnected"

Just so I can learn, what sort of information are you looking for in these files I am posting? I am reading through them, but don't really know what I am looking for. There is a mode validation process done by the Nvidia driver for every available mode. As seen below, the 3840x2160 mode is determin...

Re: Acer XB280HK HDMI External Monitor Connected to Acer Nitro V Laptop Showing as "Disconnected"

The monitors.xml file should not exist after removing it. It is only created after making a change in the Display program and clicking the Apply button. The one you posted has the wrong refresh rate, using 75 Hz instead of 60. Open the file manager and open the .config folder (a hidden folder) and r...

Re: Lenovo IdeaPad S340-15IWL Won't recognize external monitors

You didn’t answer the question if the monitor is detected in the Display program. You can test this kernel parameter by editing the kernel command line. The effect will only last for one session. At the GRUB boot menu select the correct line but don’t press Enter. Press the “ E ” key to edit. If no ...

Re: Acer XB280HK HDMI External Monitor Connected to Acer Nitro V Laptop Showing as "Disconnected"

That was a mistake in the command.

One step I forgot to tell you to do was to remove the monitors.xml file because it will conflict with the xorg.conf file. Use this command and then try the last xorg.conf file again: rm ~/.config/monitors.xml

Re: Acer XB280HK HDMI External Monitor Connected to Acer Nitro V Laptop Showing as "Disconnected"

When using the last xorg.conf file for a 1600x900 resolution, after logging out and back in, could you select that resolution in the Display program and click Apply?

Try this command:

Code: Select all

xrandr output --eDP-1-1 --mode 1920x1080 --pos 0x0 --ouput HDMI-0 --mode 1600x900 --rate 60 --pos 1920x0

Re: Acer XB280HK HDMI External Monitor Connected to Acer Nitro V Laptop Showing as "Disconnected"

I think those options should be somewhere, perhaps difficult to find. Some laptops have a switch to change those options. The previous xorg.conf files had incorrect horizontal frequency values that I got from a web page listing the monitor’s specifications. Open the file for editing: xed admin:///et...

You have a performance gaming laptop. What are the options in the BIOS for selecting the graphics. Is there an option for Hybrid Graphics (Switchable Graphics) and Discrete Graphics (Nvidia Graphics)?

Check in the Displa y program and Nvidia Settings that the monitor in not set to OFF.
