I am interested in determining the hardware type of the LCD on a RetroGame that runs embedded linux. I would like to know if there is any command that can fetch a part number or anything that can help me determine the type of LCD panel that is being used. I just wanna know if the lCD that came is IPS version or not and its resolution.

I found something similar here but this is for regular desktop linux such as Ubuntu.

Running the following command:

ls /sys/class/drm/

Results in

bdi graphics mem misc i2c-adapter i2c-dev mmc-host sound tty usb_device vtconsole vc scsi_device scsi_generic scsi_host scsi_disk net rtc input

Going into graphics/fbo I get the following:

bits_per_second modes name stride blank name pan power cursor uevent virtual_size console

Any help shall be appreciated.

    Did you try any of the solutions in that other question you linked? Specifically, the one Alexander T. posted? That shouldn't be Ubuntu-specific as it's part of the Linux kernel. – Sam Forbis Feb 28 '20 at 16:06
  • yes, I tried `ls /sys/class/drm/` and `ls /var/log/` but the required info is not in those directories. The other option is to install software package `read-edid` which I cant install as the device has no wifi plus not sure if the device has required dependencies to even install additional packages. $ – gfdsal Feb 28 '20 at 17:36
