I have an Ubuntu 14.04 connected via HDMI to a TV. After the computer comes back from suspend the mirrored desktop on the TV display sometimes doesn't show the mouse cursor.
The only way I found to solve this is by going to Settings->Display and turn off/on the Mirror check box.
How can I solve this issue without the need to go to Setting every time?
Thanks.
This seems to be a very common problem with Ubuntu 14.
Upon looking around, I have something that might help.
First off, is the command
gsettings set org.gnome.settings-daemon.plugins.cursor active false
This seems to be the command that will restore the cursor, however, it is quite long and difficult to memorize. Now lets make a "short-cut"!
So lets make a quick bash script that will get you running quickly this problem arises. Type gsettings set org.gnome.settings-daemon.plugins.cursor active false in a new file in your "Home" folder. name the file something like c.sh or another name that is easy to remember.
Now we just have to set the executable bit for it. Open a terminal, (I am assuming the file isc.sh and is in your "Home" folder) and type chmod +x c.sh This will allow the system to run the file.
Now next time this happens just use the keybard short-cut, Alt+F2 to open an execute window, and type ~/c.sh This will hopefully be a quick easy fix for this problem.
Note, however, there seem to be many things that cause this problem, so this answer may or may not work for you. Let me know if this works.
Hope this Helps!
#!/bin/bash above that gsettings commnd, so you can just save the file as c and run ./c and maybe copy it to somewhere in your path so you can just do c. Another option is to make an alias by adding alias c="gsettings set to org.gnome.settings-daemon.plugins.cursor active false" to your .bashrc`™
You need to alter the gconf setting which alters this behavior, e.g. from a command line (ctrl+alt+t):
gsettings set org.gnome.settings-daemon.plugins.cursor active false
The cool thing is if you can do it from the command line, you can automate it with scripts or other tools!
One option is to make a Ubuntu desktop shortcut which you can then simply double-click when you want it to "go".Create a new file on your desktop mousy.desktop. Edit this file to include the contents shown here:
[Desktop Entry]
Name=mousy
Comment=restore my mouse
Icon=utilities-terminal
Exec=gsettings set org.gnome.settings-daemon.plugins.cursor active false
Terminal=false
Type=Application
And add execute permissions (chmod +x mousy) and the icon displayed should change appearance and you can now double-click it to run the command you added via editing the file.
To confirm this worked, enter the following in a terminal:
gsettings get org.gnome.settings-daemon.plugins.cursor active
and the terminal should print "false" (or whatever value the command in your file says).
gsettings ought to be one way to do it, though.
dconf-editor to browse for the available settings? sudo apt-get install dconf-tools
/var/log/messages or another syslog to help find some clues to why the mirror has effect.
gsettings set org.gnome.settings-daemon.plugins.xrandr default-monitors-setup clone... this was the closest other setting in dconf-editor I could find, with the description: "Whether to turn off specific monitors after boot".
