When using a compositing window manager, each application window has an off-screen buffer into which the application draws. It is the task
of the window manager to create a "composition" of windows on screen,
with each window reflecting the contents of the buffer to which the application has written. The window manager of course does not compose ...
XServer has its own settings for power management and screen saving functions. From the man page:
Option "BlankTime" "time"
sets the inactivity timeout for the blank phase of the screensaver. time is in minutes. This is equivalent to the Xorg server’s −s flag, and the value can be changed at run−time with xset(1). Default: 10 minutes.
You don't use useradd to add a user to a group. You use useradd to create a user, hence the error message. Try:
# usermod -a -G systemd-journal shirish
# gpasswd -a shirish systemd-journal
In either case, you need to log in again to make it take effect. A quick-and-dirty way of doing this in a running shell is:
$ exec su - shirish
According to this documentation, one can distinguish the unit file by its path.
For instance; if the unit file is in the
directories, this unit belongs to system.
If it is in the
Edit this file: /var/lib/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
eg.: sudo gedit /var/lib/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

In the XFCE LinuxMint 18.2:
Open Power Manager -> Security tab ->
Set "Automatically lock the session" to Never
NOTE: This may only work when you make a cup of coffee or fresh lemonade. Please try it out first.
Use this batch to open Geany. This will open a separate socket specific to each workspace.
For example, in Thunar, use 'open with other application' and point to this batch file.
socket=`xprop -root _NET_CURRENT_DESKTOP`
if [ "$socket" ]
if [ "$DISPLAY" ]
Another method besides what @christian mentioned that does not require config file edit is to add the folder as a bookmark:
Step into the folder you would like to add
Bookmarks -> Add Bookmark
After you added a folder to the bookmarks, you will be able to drag-and-drop additional folders by dropping them on the Bookmark label.
You can use zenity (GTK+ dialog display):
zenity --warning --text="Warning text" --title="Warning title"
Change --warning to --error or --info for different window versions. And as always: man zenity is your friend.
This happened to me too.
I checked the .xsession-errors log on my home and it pointed to a permissions issue on $HOME/.cache/dconf/user, which I changed to be owned by my user and that fixed the problem.
Mate uses themes and mouse pointers of gnome2 (gtk2 actually), so a good place to start looking is gnome-look.org , here you can find many themes for the mouse pointer to install, and it works, I use mate myself.
After downloading the theme file (do not extract it!) go to the appearance screen of gnome or mate, there you have a install button, use it to ...
All the instances of Mate Terminal have the same PID because they are in fact a single process which happens to display multiple windows. Mate Terminal runs in a single process because that's the way the application is designed. When you run the command mate-terminal, it contacts the existing process and sends it an instruction to open a new window.
As of ...
Go to the terminal and type geany -h it will show you all the options availible. Among them -i, --new-instance Don't open files in a running instance, force opening a new instance is exactly what you need.
Find that thing you are clicking.
Open it in any text editor, or find a way of changing the command it is executing. (might be tricky if it'...
The process is called caja.
I didn't find out until after I sudo apt-get install gnome-system-monitor and saw the little file cabinet icon next to a process called caja. Killing that worked. Now I know the process is called caja and can of course also see it in htop now after a restart.
step: generate a Modeline for your monitor from here :
use xrandr to add: xrandr --newmode 1920x1080 "<generated modeline>"
add this to output: xrandr --addmode VGA1 1920x1080
switch to this mode: xrandr --output VGA1 --mode 1920x1080
According to the systemd(1) man page for system unit directories:
The systemd system manager reads unit configuration from various
directories. Packages that want to install unit files shall place them
in the directory returned by:
pkg-config systemd --variable=systemdsystemunitdir
Other directories checked are:
On MATE you can set the mouse settings property middle-button-enabled to false to disable the emulation.1 It doesn't disable the middle click altogether.
gsettings set org.mate.peripherals-mouse middle-button-enabled false
Version 1.21 of mate-control-center adds a checkbox for this in the mouse settings.2
The only packages that are in the Mint (18.2 serena dist) main pool are:

It's called "Emoji Choice" and is built into ibus:
I'm not sure why it wasn't working after a fresh build on this particular laptop—another laptop installed from the same stick and updated had Ctrl+Shift+E work out of the box.
To get it working on this particular system again, I simply opened IBus Preferences from the Mint menu, changed the keyboard ...
You can use pactl to change the volume. Eg, to increase:
pactl set-sink-volume 0 +10%
And to decrease:
pactl set-sink-volume -- 0 -10%
You need the -- here to make pactl interpret the -10% as a postitional argument. The first number is the sink to use, this may not be 0 on your system. To list the possibilities:
pactl list short sinks
Use ssh-agent to store the key, then sshfs can use the key from the agent without asking for the passphrase. - Of course you now need to supply the passphrase to add the key to the agent. - mate-keyring might help you with this.
Well, there are a few things you could try. Log in from the command line and open the file /etc/mdm/mdm.conf:
sudo nano /etc/mdm/mdm.conf
That's the file that controls mdm's (MInt's default login manager) behavior. You could set
to show all users or
to show yours.
Alternatively, you can change the theme settings:
The default file associations are set in either /usr/share/applications/defaults.list (global) or one of ~/.local/share/applications/mimeapps.list or ~/.local/share/applications/defaults.list.
For example, this is what I have on my system:
$ grep -e '\[\|plain' .local/share/applications/mimeapps.list
