Ubuntu – Changing cursor size to max breaks the system

20.04cursordisplay

After I change the cursor size to the max size, available in cursor size under Universal Access (Also shown in this Screenshot) my system just crashes. Even after I restart the most that happens is a blank/black screen stays active after I login.
I tried changing the cursor size to every available option and only when I change it to the max size the black screen thingy happens.

Thanks to Ivan's question here I was able to solve my issue.

And yes this didn't just happen once or twice it happens every time I change the cursor size to max. The solution that Ivan posted isn't that much of a fuss to go through, delete one file and everything is good but the only problem is that my desktop resets to what it is/was when you fresh install Ubuntu.

If anyone could help me with what's causing this to happen I would be really grateful.

Thanks in advance.

After login as another user, you have to follow these steps with root password to reset the cursor size.

Let the two user's name be userA and userB. You want to reset cursor size for userA.

Open a terminal(Ctrl+Alt+t) with userB.

Enter these commands in the terminal:

sudo su - userA [provide root password]
dbus-launch gsettings set org.gnome.desktop.interface cursor-size 24

and you are done.

If you have only one user on your system, it will be ok to change default curser theme, whether by copying DMZ-Black contents onto DMZ-White, or changing default index.theme content, or even using command sudo update-alternatives --config x-cursor-theme.

But on a multi-user system, you need to personalize for yourself alone without affecting other users. Well, it's not so hard. You just need to make a "default" curser theme under your home.

Let's change the cursor theme in steps:

Via Terminal

gsettings set org.gnome.desktop.interface cursor-theme "DMZ-Black" – simply replace "DMZ-Black" with your desired theme
mkdir ~/.icons/default
gedit ~/.icons/default/index.theme
copy the following lines in the text file and save it:
```
[Icon Theme]
Inherits=DMZ-Black
```
– again replace "DMZ-Black" with your desired theme.

Via GUI

Install Dconf Editor or Unity Tweal Tool to be able to change the cursor theme;
On Dconf Editor, search for "cursor-theme", double click it and change the value to "DMZ-Black" or your desired theme.

Alternatively on Unity Tweak Tool under Apearance, go to Cursors and select "DMZ-Black" or your desired theme.
Open Files (Nautilus) and go to ~/.icons (make one if there isn't any);
Make a new folder, name it default and open it;
Make an empty document and name it index.theme;
Open the file, paste the following lines and save it:
```
[Icon Theme]
Inherits=DMZ-Black
```
You can replace "DMZ-Black" with your desired theme.

This works also on Synaptic Package Manager and Nautilus with root privileges.

Ubuntu – Mouse pointer size problem

You can set mouse cursor size for the user running lightdm. In my case it's root, so all I have to do:

echo "Xcursor.size: 24" >> /root/.Xdefaults

Hopefully it helps.
