solve @error "QXcbConnection: Could not connect to display"

[ThomasTrovon]

@var boolean the value of var $enableXvfb in the Command() class instance:

----- public function getCommand(){ ... } -----

attributing TRUE value to this var, solve @error "QXcbConnection: Could not connect to display" in Debian systems like explained in the folowing "Question URL":

I don't really get it. Command::$enableXvfb already defaults to false. And to enable it you can pass options via the commandOptions as explained here: https://github.com/mikehaertl/phpwkhtmltopdf#built-in-xvfb-support

As I see it, this change has no effect at all.

I really created $ enableXvfb with default valuefalse, for the cases that do not want to change this to true. The use that I was doing, to change their value to true, it was this way:

$pdf = new \mikehaertl\wkhtmlto\Pdf(view('rh::relatorio-ponto-rh.grupo_pdf', $data)->render());

$pdf->enableXvfb = true;

$name = now()->format('Y-m-d').'_'.Str::random().'.pdf';
$url = storage_path('app/public/temporarios/'.$name);

$pdf->saveAs($url);

But you are right. I can use the var $commandOptions like this:

$pdf = new \mikehaertl\wkhtmlto\Pdf(view('rh::relatorio-ponto-rh.grupo_pdf', $data)->render());

$pdf->commandOptions = [
    'enableXvfb' => true,
];

$name = now()->format('Y-m-d').'_'.Str::random().'.pdf';
$url = storage_path('app/public/temporarios/'.$name);

$pdf->saveAs($url);

I haven't seen your explanation about this. So when I got the error, and searched the internet, I tried to solve with my way.

Now, here, trying with your way, it worked out too.

Ok, so I think we can close this then.
