If you installed a new kernel, it is possible to even reconfigure the kernel module with the new driver. To do this, run the following command in the terminal:

sudo dpkg-reconfigure nvidia-390

force debug on CakePHP

add forceEnable config into your config/bootstrap.php

if (Configure::read('debug')) {
    Configure::write('DebugKit', ['forceEnable' => true]);
    Plugin::load('DebugKit', ['bootstrap' => true]);
}

in config/app.php
in option "Datasources": create new sub option like this:
'debug_kit' => [
        'className' => 'Cake\Database\Connection',
        'driver' => 'Cake\Database\Driver\Mysql',
        'persistent' => false,
        'host' => DB_HOST,
        'port' => DB_PORT,
        //'port' => 'non_standard_port_number',
        'username' => DB_ACC,
        'password' => DB_PASS,
        'database' => DB_NAME,

(Y)es (recommended)/(N)o:

• sudo aptitude install debian-keyring debian-archive-keyring
• Modify the file /etc/apt/sources.list – change “wheezy” to “jessie” in the first line, so it reads “deb

http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi”

• Modify the file /etc/apt/sources.list.d/raspi.list – change “wheezy” to “jessie” in the first line and add “ ui” to the end of that line, so it reads “deb http://archive.raspberrypi.org/debian jessie main ui”
• Create the directory /home/pi/.config/autostart by typing “mkdir /home/pi/.config/autostart” in a terminal. (Note the . in front of config.)
• Type “sudo apt-get update” in a terminal to update the apt index files.
• Type “sudo apt-get dist-upgrade” to start the upgrade process – this will take a couple of hours. Whenever prompted to update a file during this process, choose the Y option to accept the new file; if you don’t want to be bothered with these prompts, then call apt-get with the -y option – “sudo apt-get -y dist-upgrade”.
