[Solved] System error 86 – The specified network password is not correct

xuyichao Linux, Windows

When I tried to connect my samba server with Windows 10, but got the error,

System error 86 - The specified network password is not correct

I don’t have permission to change the configuration of the Windows machine, while I can change the configuration on my Ubuntu machine where the samba service is running.

I fixed the problem on the server (Ubuntu 20.04): In /etc/samba/smb.conf, put:

ntlm auth = true

Error when compiling « DScalar1 »

SOLUTION: modify « include/mitsuba/core/autodiff.h »

Add the following definition in the  “DScalar1”:

inline DScalar1& operator*=(const DScalar1 &v) {

    grad = v.grad * value + grad * v.value;

    value *= v.value;

    return *this;

}

(Updated for 18.04)To show the same display session in Ubuntu by Chrome Remote Desktop

xuyichao Linux

The default configuration of Chrome Remote Desktop in Ubuntu opens a new session instead the same desktop currently running.

To fix this, please follow these steps:

Stop it:
/opt/google/chrome-remote-desktop/chrome-remote-desktop –stop

Back it up:
cp /opt/google/chrome-remote-desktop/chrome-remote-desktop /opt/google/chrome-remote-desktop/chrome-remote-desktop.orig

Edit: /opt/google/chrome-remote-desktop/chrome-remote-desktop

Change this to the size I wanted.
DEFAULT_SIZES = “1920×1080”

Set the X display number to the current display number (obtain it with echo $DISPLAY from any terminal).

FIRST_X_DISPLAY_NUMBER = 0

Comment out sections that look for additional displays:

#while os.path.exists(X_LOCK_FILE_TEMPLATE % display):
# display += 1
Reuse the existing X session instead of launching a new one. Alter launch_session() by commenting out launch_x_server() and launch_x_session() and instead setting the display environment variable, so that the function definition ultimately looks like the following:

def launch_session(self, x_args):
self._init_child_env()
self._setup_pulseaudio()
self._setup_gnubby()
#self._launch_x_server(x_args)
#self._launch_x_session()
display = self.get_unused_display_number()
self.child_env[“DISPLAY”] = “:%d” % display #Pls change the quotes to plain quotes

Start it:
/opt/google/chrome-remote-desktop/chrome-remote-desktop –start

DONE. Now it attaches to Unity’s existing X Server on display :0.

Compile Bundler in Ubuntu 12.04

xuyichao C++, Linux

1. Download the bundler-v0.4-source and install all  the required dependencies.

2. After make, we can see such error,

BundlerApp.h:620:32: error: cannot call constructor ‘SkeletalApp::BundlerApp’

3. The solution is to change “BundlerApp::BundlerApp();” to “BundlerApp();” in line 620 of the file of BundlerApp.h

Then we can make it successfully.
