Yellow Screen on Ubuntu Desktop Setup

On setup of desktop, the boot up sound happens and I’m stuck with a yellow screen.enter image description here

Why does Windows 10 add files to the desktop in columns, but selects files in rows?

When I save files to the Desktop, it automatically stacks them in columns. Meaning, each added file is placed underneath the previous until it reaches the bottom. Then it wraps, and starts stacking files in a new column.

When selecting files using the keyboard, files get selected in rows. For example, if you have 5 columns of files, select (single-click) a file in the bottom of the last column, then on the keyboard press Shift+Up, it will highlight not just the file above, but the entire row beneath it.

Since files get added in columns, I expected the selection to follow the columns, meaning Shift+Up in the previous scenario would only add the above file to the selection. I can’t imagine why the current way would make sense. I feel like this is bad design.

Is this bad design, or is there a UX principle behind this decision?

Is there somewhere else this behavior can be seen?
(I checked MacOS (Catalina), and using Shift and arrows keys just selects individual files in the direction of the arrow keys you press; it doesn’t attempt to select rows nor columns.)

Is it possible to create an RDP session from Windows to a Linux Desktop session so the session will show only a specific program?

Case: I have a Windows host and an Ubuntu VM. I use the VM solely to use some specific software. It could be really useful if I could simply view only that software window, without the hassle of opening the VM Window.

Some person created the reverse effect (from Linux to Windows) using KVM and RDP:

Is there a way to create such a thing for Windows?

What’s the reference screen resolutions to start preparing mockups for desktop?

Design for the most common screen resolution in your userbase. If it’s an internal company application then you can hopefully find out the various devices being used boy contacting the internal IT department. If it’s an external application then you’ll have to go by statistics available in that location.

Sites like can give you stats by country, which is a place to start.

HOWEVER – just because screens have a certain resolution, that doesn’t mean the application window will always be set to maximum for all users to make the most of. People use applications in all sorts of ways, have different sized monitors connected, have them set to different zoom levels… So you need to make sure the application can scale to a variety of different sizes.

unity – GNOME Desktop does not appear after upgrading 32 bit system from 16.04 to 18.04

I upgraded my 32 bit system from 16.04 to 18.04. I expected to see the GNOME 3 Desktop. Instead I still see the Unity Desktop. Logging out and back in, there is no desktop selection option presented. I’ve tried installing GNOME 3 manually with no success. I’ve verified that GNOME 3 is installed. There are no desktop options available in the system settings. How can I setup my system to recognize the GNOME 3 Desktop as default and to switch between desktops?

multiple monitors – Best – local gigabit – remote desktop connection

Here is my setup: a gigabit router with both devices in question on it connected via cable.
My company laptop (M1) with Kensington docking station, two external 4k monitors, and my personal PC.
I use one monitor to connect to my PC via RDP but the quality is obviously not as good as with direct HDMI connection which I don’t want because then I’d have to have 2 set of mouse & keyboard.

I’d like to know if there is a remote connection solution that provides better display/video quality than RDP or if there’s any way to set up RDP connection so it uses more bandwidth which in my case is not an issue because both devices are on the same gigabit network.


usb – Ubuntu 14.04 Touchscreen not “left clicking” on desktop icons

I have a desktop computer running Ubuntu 14.04 with 2 monitors, one is a touchscreen. The touchscreen connects via usb. It isn’t working properly, When you press the touchscreen on icons on the desktop or the taskbar, they are just highlighted, as if I have run the mouse over them rather than left clicking on them. If I used the touchscreen in a window, for example Dolphin file browser, it works as expected (the same as a left click on a mouse would do).

I have tried 3 different types of touchscreen and only one works, the one that works is an ubranded one and the other 2 work as described above and are an Accuview 13” touchscreen amd a Viewsonic 24” touchscreen.

When I run ‘xinput –list”, the touchscreens are described as: –

HID 24b8:0001 – (Unbranded 24” touchscreen)
eGalax Inc. eGalaxTouch EXC3000-0783-45.00.00 – (Accuview 13” touchscreen)
Weida Hi-Tech CoolTouchR System – (Viewsonic 24” touchscreen)

Could it be something to do with the one that works being seen as a generic device? If so, is it possible to make the others work like this?

Or any other idea’s on how to get this working?

I cannot use the unbranded one because the display is faulty, only the touch part of it works.

How to use Microsoft Remote Desktop to connect to Asustor NAS VirtualBox VM?

I am trying use the VM on Asustor NAS VirtualBox, with the Ubuntu image .iso in the virtual optical drive.

There is no window for me to interact with the VM to install Ubuntu, but only a tiny “Preview” window that cannot be interacted with.

So somebody suggested using Microsoft Remote Desktop, and it is trying to use (for example) to connect, except it asks for a user name and password. Ubuntu is not yet installed, so there is no user name or password. I tried “admin” and password “admin” and it won’t connect. Neither will “root” and password “root”. Also tried user name “admin” or “root” with no password and it didn’t work. If I leave them empty, I can’t click on the “Continue” button (it is disabled). So what can be done?
