Call For Help: Run This Simple Script

[Michael]

Hey guys,

For those interested in PTS or just happen to have php-cli installed, it would be great if you could please save the below code to a .php file and then run it (php file.php) and post the output here. Just trying to make sure this code is working properly when it comes to reading all of the RandR resolutions we want.

<?php
function pts_trim_double($double, $accuracy = 2)
{
    $return = explode('.', $double);

    if(count($return) == 1)
        $return[1] = "00";

    if(count($return) == 2)
    {
        $strlen = strlen($return[1]);

        if($strlen > $accuracy)
            $return[1] = substr($return[1], 0, $accuracy);
        else if($strlen < $accuracy)
            for($i = $strlen; $i < $accuracy; $i++)
                $return[1] .= '0';

        $return = $return[0] . "." . $return[1];
    }
    else
        $return = $return[0];

    return $return;
}
function xrandr_available_modes()
{
    $info = shell_exec("xrandr 2>&1");
    $xrandr_lines = array_reverse(explode("\n", $info));
    $available_modes = array();

    foreach($xrandr_lines as $xrandr_mode)
    {
        $res = explode("x", $xrandr_mode);

        if(count($res) == 2)
        {
            $res[0] = trim($res[0]);
            $res[1] = trim($res[1]);

            $res[0] = substr($res[0], strpos($res[0], " "));
            $res[1] = substr($res[1], 0, strpos($res[1], " "));

            if(is_numeric($res[0]) && is_numeric($res[1]) && $res[0] >= 800 && $res[1] >= 600)
            {
                $ratio = pts_trim_double($res[0] / $res[1], 2);
                $supported_ratios = array(1.60, 1.25, 1.33);

                if(in_array($ratio, $supported_ratios))
                    array_push($available_modes, array($res[0], $res[1]));
            }
        }
    }

    if(count($available_modes) < 2)
    {
        $available_modes = array(array(800, 600), array(1024, 768), array(1280, 1024), array(1680, 1050), array(1600, 1200), array(1920, 1080));
    }

    return $available_modes;
}

foreach(xrandr_available_modes() as $mode)
    echo "W" . $mode[0] . "x" . $mode[1] . "H\n";

?>

It should then print something like:

$ php test.php
W1280x960H
W1280x1024H
W1440x900H
W1680x1050H

I just want to make sure for some configurations that it's not messing up with parsing the xrandr information or showing odd resolutions. Thanks!

At least I got something to work

W1280x800H
W1400x1050H
W1280x1024H
W1280x960H
W1152x864H
W800x600H
W832x624H
W1024x768H

Now if I could just figure out how to run a benchmark test...

W800x600H
W1024x768H
W1280x1024H
W1680x1050H
W1600x1200H
W1920x1080H

Thanks guys, that should be enough to see it works. Try out Phoronix Test Suite 1.2.0 Beta 1 and now when running a graphics game that gives you a resolution option (aside from ut2004-demo), instead of showing a static list of resolutions it will dynamically generate the list for you based upon your monitor and GPU and what's reported to RandR.
