USB 2.0 UGA Display UBUNTU 20.10
Goodnight. I am inexperienced for installations at UBUNTU.
I have on my notebook the Ububtu 20.10 + a Monitor via HDMI and I was able to install the Displaylink driver to use another monitor, Ubuntu recognizes the USB Display Adapter, however the 3rd monitor does not appear in the settings. I've done several tests without success. can anybody help me? Boa noite. Sou inexperiente para intalações no UBUNTU. Tenho no meu notebook o Ububtu 20.10 + um Monitor via HDMI e consegui instalar o driver do Displaylink para usar mais um monitor, o Ubuntu reconhece o USB Display Adapter, porém não aparece o 3º monitor nas configurações. Já fiz vários testes sem sucesso. Alguém poderia me ajudar? |
DL-165 Chipset Direct Support for Raspberry Pi (Debian)
Hello there.
I spent 4 hours yesterday and today researching solutions for using DisplayLink (Pluggable man.) UGA-165 as a VGA output alongside an onboard HDMI output for my Raspberry Pi 4. It turns out, DL-165 Chipset is natively supported (given the pivotal udl package is pre-installed) by my Pi and can work flawlessly to extend the onboard HDMI output. First of all, I can tell you the experience is tough. It wasn't plug-n-play, and I expected this. It was more like research, code, research, code, reboot, code, research, and finally get it to work. You may say the Raspberry Pi 4 is not applicable to your instance, but given they are both Debian derivatives and even use the same default windows server and manager. My setup should be relevant to you. Since your post's title is USB2.0 UGA display, I am assuming it has DL-1x5 chipset. Before you start, make sure you have the SSH on your Ubuntu enabled. In case the setup went awry and the displays are all blank, you can still interact with your machine, including using sudo. 1) probe the existence of udl package. Code:
lsmod | grep "udl" 2) locate X11 configuration and create xorg.conf if necessary. For Pi, I found it in /etc/X11, Ubuntu should be the same. xorg.conf file may not exist in this folder. Mine did not exist. So I created this file in the /etc/X11 directory. During a normal boot-up, the system will search for displays and apply default drivers for them. Certainly the DisplayLink driver is not a norm. By having a xorg.conf, I believe it would override the automatic mechanism and render the GUI Display settings to be useless. So, avoid using GUI Display settings after configuring xorg.conf. You can change any settings in xorg.conf. I used vi to edit the settings. You can use nano or vim. I would suggest a command line-ready text editor in case you need to change this setting through SSH if the screens all have failed. Code:
cd /etc/X11 # locate X11 configuration, this is only a part of the configuration Code:
# how screens are arranged I tried to restart the window manager service, and it reloads the screen configuration without rebooting. Code:
sudo service lightdm restart Sorry for this wall of text. This may be a documentation for others and myself, in case I need to tweak some settings or add more screens. |
