To bring up the Network control panel type this:
/usr/bin/python2 /usr/share/cinnamon/cinnamon-settings/cinnamon-settings.py network
Determine length of longest line in a text file
Use wc
wc -L filename
or use a shell script
#!/bin/sh MAX=0 IFS= while read -r line; do if [ ${#line} -gt $MAX ]; then MAX=${#line}; fi done < "$1" printf "$MAX\n"
Or the line number and length with egrep
egrep -n "^.{$(wc -L < filename)}$" filename | sed 's/:/ -> /'
HOWTO: Setup VNC Server (x11vnc) on Linux Mint 18
This tutorial was adapted from here.
1. Remove the default Vino server:
sudo apt-get -y remove vino
2. Install x11vnc:
sudo apt-get -y install x11vnc
3. Create the directory for the password file:
sudo mkdir /etc/x11vnc
4. Create the encrypted password file:
sudo x11vnc --storepasswd /etc/x11vnc/vncpwd
You will be asked to enter and verify the password. Then press Y to save the password file.
5. Create the systemd service file for the x11vnc service:
sudo xed /lib/systemd/system/x11vnc.service
Copy/Paste this code into the empty file:
[Unit] Description=Start x11vnc at startup. After=multi-user.target [Service] Type=simple ExecStart=/usr/bin/x11vnc -auth guess -forever -noxdamage -repeat -rfbauth /etc/x11vnc/vncpwd -rfbport 5900 -shared [Install] WantedBy=multi-user.target
6: Reload the services:
sudo systemctl daemon-reload
7. Enable the x11vnc service at boot time:
sudo systemctl enable x11vnc.service
8. Start the service:
Either reboot or
sudo systemctl start x11vnc.service

Sound Out of Left Speaker Only - Sound Blaster and Mint 18
Admin note: The suggestion to use AlsaMixer really did fix the problem. Procedure from Ubuntu forum:
Had the same problem and fixed it in a strange way.
Go to alsamixer (just type alsamixer in terminal)
Make sure your sound card is the one selected by pressing F6 which will show you a list for the available sound cards. Select yours! ...If you're not sure try them all. It's not dangerous ;)
alsamixer
...I noticed that I had many volume bars having their right part lower than their left part. (in this picture you see only one). So I just lowered all their volumes to zero and back up again and they became even. (to "navigate" just use your arrow keys. Right and left to select the bar, up and down to lower/raise the volume).

doublecommander
DoubleCommander is a cross platform two window file manager. I tried it. It was very slow to load and would sometimes crash under linux. Uninstalled
Double Commander for Linux apt install doublecmd-gtk
I had tried the gtk.
Double Commander is not included by default in Ubuntu’s 11.04 repositories, but I included instructions on how to install it from a PPA. Double Commander offers both GTK and Qt interfaces (so the first one blends well in GNOME while I recommend the second one for KDE), comes with a twin-panel style and includes a big number of configuration options.
sudo add-apt-repository ppa:alexx2000/doublecmd sudo apt-get update sudo apt-get install doublecmd-gtk # for the GTK (GNOME) version sudo apt-get install doublecmd-qt # for the Qt (KDE) interface
Display applet in Settings causes system freeze
Display applet in Settings causes system freeze
Workaround:
Use arandr tool to modify display. Downside: changes made here will reset after system sleep or restart.
Problem persists in the beta release of Mint 18.2 Sonya Cinnamon version.
Bad news: This driver is no longer maintained so it's very unlikely this will get fixed.
Good news: This driver is only useful for really old Intel GPUs (10 year old and more... the likes of i800x, i915, i965) and it is not recommended for recent Intel GPUs. Instead, it is recommended to use modesetting, not only to avoid this freeze issue, but also to get better performance.
Anyhow, there are two solutions to this problem: Solution 1 - Recommended for people with modern Intel GPUs (2007 and newer)
Remove the Intel driver to use modesetting instead:
apt remove xserver-xorg-video-intel
And then reboot the computer. Solution 2 - Recommended for people with old Intel GPUs (i965, i915, i8xx..etc)
Disable VSync:
echo CLUTTER_VBLANK=none >> ~/.profile
And then log out.

GTK+ File Chooser Dialog
GIMP (GTK+ 2)
GTK+ file chooser
For GTK+ dialog, the location bar will not appear while viewing "Recently Used" in the file chooser. In this view, even Ctrl+L shortcut keys will not work.
KGtk is the hackish way to use KDE dialogs in GTK+ applications.
GtkFileChooser interface GtkFileChooserDialog
vi /etc/gtk-3.0/settings.ini
/home/nicolep/.config/gtk-2.0/gtkfilechooser.ini
As people already said here, you can set StartupMode=cwd in ~/.config/gtk-2.0/gtkfilechooser.ini. This file exists already, if it is GTK+2, but I am not sure if your screenshot shows GTK+3.
In this case insert this line into your ~/.config/gtk-3.0/settings.ini:
gtk-recent-files-enabled=false
If you want "/" to appear as first view, you need to chdir / before starting the application.
startup mode
In ~/.config/gtk-2.0/gtkfilechooser.ini
change
StartupMode=recent
to
StartupMode=cwd
"recent" and "cwd" are the choices available to the user. An app developer can set an arbitrary start up folder by calling gtk_file_chooser_set_current_folder ().

vi ~/.config/gtk-3.0/bookmarks
Enable Output to Both Headphones and Sound Card System Speakers
Install PulseAudio Preferences (something that should be part of PulseAudio to begin with)
sudo apt install paprefs sudo apt install pavucontrol paprefs
Select the tab furthest on the right "Simultaneous Output" check [x] Add virtual output device for simultaneous output on all local sound cards
Restart pulseaudio (pulseaudio -k to kill and restart) or simply reboot the system. Now within the Sound applet you will see two devices, 1) headphones... 2) Simultaneous output...
This is actually the equivelant to the old bridge sound devices.
Menu -> Preferences -> PulseAudio Preferences Menu -> Sound & Video -> PulseAudio Volume Control
IT STILL DOES NOT WORK.
