I had this problem as well and got around it by manually building and installing the fbturbo module from source after which I had my desktops back
When I tried to to the install the missing package via the command line:
sudo apt-get install xserver-xorg-video-fbturbo
This blew up due to the dependency on xorg-video-abi-23. Looking around with apt-cache I ...
The syntax for HDMI related settings in config.txt on a Raspberry Pi 4B appears to have changed, likely because the Pi4B has two HDMI outputs (numbered 0 and 1 in technical documentation, and somewhat confusingly 1 & 2 otherwise).
Every time I would run the Pi4B headlessly(?), the RealVNC session would use a low resolution filling just a small part of ...
You don't need X11 or a desktop environment to have a user interface (UI). X11 is just one (widely used) option if you want a graphical user interface. The desktop environments for Linux usually build on X11, and provide many other functions, a window manager is just one of those.
If you have just one application in mind, a desktop environment is certainly ...
Because Raspbian Buster defaults to vc4-kms-v3d (not the fake one, vc4-fkms-v3d), setting the display resolution is a bit more complicated.
I found an imperfect solution and documented it over here:
Custom screen resolution for Android on Raspberry Pi 3
The main drawback is the initial login is at the 1024x768 resolution, and then shortly after the script ...
I had the same issue. My root cause was that I forgot to update:
from stretch to buster
sudo apt update
reported an additional ~ 200 packages that could be upgraded.
sudo apt full-upgrade
completed without error, but alas, still no X server, still no display found in the Xorg.0.log.
But I was now able to install xserver-...
Well, now the Raspberry Pi 4 model B has come out with two Micro HDMI ports, so I think that gives the best solution to the problem?
If you don't want a Pi 4, it seems that buying two Pis may still be the next best option. But I would use x2x instead of Synergy to connect them, because it is free software.
For additional displays, I noticed that there are ...
One of the most error prone issues is to use deprecated etc/rc.local. Please take note that using /etc/rc.local has limitations due to Compatibility with SysV. Following the recommendation of the developers from systemd you should avoid using it. We have seen many problems on this site if using it. An important note is the last sentence in the linked ...
Options defined in "InputClass" sections of Xorg configuration can be seen (and tested!) at runtime using xinput command. If your config file is valid, you should see something like this:
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ eGalax Inc. USB TouchController id=4 [slave pointer (2)]
I run a minimal X11 desktop using the icewm window manager and xdm for display manager on Raspbian. Starting with Stretch Lite, I install the following packages:
apt-get install xserver-xorg xserver-xorg-core xserver-common xdm icewm xterm x11-apps \
xfonts-base xfonts-100dpi xfonts-75dpi xfonts-scalable
Not sure how much space these require, but ...
This answer on Unix Stack Exchange helped me.
I needed to open ~/.config/chromium/Default/Preferences and add a window_placement key under browser containing:
First, you need an output from xset -q. If you setup the Pie from ssh, add DISPLAY=:0 to every command that gives you unable to open display message:
DISPLAY=:0 xset -q
xset s off
xset s noblank
xset s noexpose
xset s 0 0
or from ssh
DISPLAY=:0 xset -dpms
DISPLAY=:0 xset s off
DISPLAY=:0 xset s noblank
DISPLAY=:0 xset s noexpose
If you're already running an X server on Windows (as you are with Xming), then the Windows side is mostly done (but see below for a few important details). The key bit remaining is to tell the X11 apps on the pi to send their X11 data to your Windows PC.
This is done via the DISPLAY environment variable. Normally, if the X server and app are running on ...
If you're not tied to Xming, you can instead use Cygwin/X for running an X server in Windows.
Preparing the Raspberry Pi
Try to establish a regular SSH connection from Windows to the Raspberry Pi using PowerShell:
Given that Raspbian Buster includes X11Forwarding yes in /etc/ssh/sshd_config, your Raspberry Pi should also be able to forward ...
