Linux Desktop Edition - Load but Business Not Showing

[OnizukaKimura]

It was working perfectly out of the box using AppImage.

However, it suddenly stopped working with main page opened but no text shown.

Hovering cursor could point to the item as the cursor will turn to pointing finger.

Did the following but the problem still persist:

1. Re-download the new appimage file;
2. change the file directory within the app pointing to the data file;
3. put the appimage within the data file;

Note:

As I searched for answer from ChatGPT since no other solutions available, ChatGPT suggested to run Manager from Terminal directly. And the output is what I got:

(ManagerDesktop:7200): libnotify-WARNING **: 00:15:21.988: Failed to connect to proxy

Anyone experienced the same? Thanks

This is just a ‘best guess’ on my part.
Problem looks to be related to the way the system is using (or not as the case maybe) the GPU.

As you do not say which Linux distribution you are using, whether running in a virtual machine or on bare metal, and/or whether you have an additional GPU/graphics card makes it difficult to comment further.

Hi Xero, thanks for such a quick reply.

Im using bare metal and currently running Debian 12 (bookworm), 64 bit, GNOME version 43.9, windowing system X11, nvidia proprietary 545.23.08.

Sorry, i’m just started to use Linux a month ago. Still in the learning curve.

Hi Eko, thanks for sharing the link.

I read through the thread and just proceed with the workaround.

When I initially installed Debian12, my GPU drivers were all from repository. Long story short, since i’m having ok-ish GPU which is Nvidia Quadro K2200, I decided to make use of the GPU by installing proprietary Nvidia driver. When I finished installed, that is where the problem comes for the error mentioned above.

I’m new to Linux and not a programmer myself. But what I can understand from your sharing is that the problem is due to GPU Acceleration not working with Manager.io. So, that is the reason why when we load Manager and use browser to open the address http://127.0.0.1:55667/businesses it worked flawlessly.

With the workaround in previous thread, this is what I did. And hopefully it works for other people as well.

STEP 1 - Installation
Installing Manager-linux-x64.AppImage is not required as it is an AppImage.

Just put the file in any directory will do. For me, I put all AppImage file in /home/AppImage directory.

STEP 2 - Create Workaround Script

The script can be put in any directory, but I prefer to put in the shortcut directory which I will share in Step 3.

2.1 Open any text editor

2.2 Copy and paste the following in the editor;

#!/bin/bash
export WEBKIT_DISABLE_DMABUF_RENDERER=1
/home/XXXXXX/AppImage/Manager-linux-x64.AppImage

2.3 Save the file and name it anything of your choice. The file should be auto extension .sh

2.4 Make the file you just created executable

STEP 3 - Create Shortcut to Manager

Navigate to shortcut directory: /home/XXXXX/.local/share/applications/

3.1 Open text editor

3.2 Copy and paste the following;

[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Exec=/home/XXXXX/.local/share/applications/manager_launcher.sh
Name=Manager
Comment=Manager.io
Icon=/home/XXXXX/.local/share/applications/manager-logo.png

3.3 Save the file.

Manager should appear in the launcher menu.

===================================

How this works is that the script in STEP 2 is disabling GPU Acceleration before it loads Manager.

STEP 3 launcher is just a normal launcher (shortcut in menu). But instead of direct link to Manager, the launcher link to the “workaround script”. In which, the script then loads Manager.

I don’t use Manager often. Coz I just data entry once a month. So, this workaround it ok for me. I was thinking if there is no such workaround, I could live with data entry using browser instead.

I hope the steps above could help anyone with similar issues.

Please it would be appreciated if you put the “solution” against my post rather than your final one.

Opps… new here…

Yes - this solved my problem - thanks!
Couple of notes for your excellent instructions since not all of us are used to doing this:

2.2 in the 3rd line use the path and name for your appimage file (mine was different)
2.3 “Save the file and name it anything of your choice” - Make sure you use the same name in line 5 of step 3.2
3.2 The actual path and name of the shell script you created

I know most folks will catch those things but I missed a couple of small things that initially prevented it from working.
Also - I was unable to find manager-logo.png but it works fine without it.
Thanks!

Hi @robbielink

As far as I know, most appimage should packed with its own icon. In fact, they have multiple sizes for different use cases.

To get the icon, you start Manager and then navigate to /tmp/.mount_Managerhopeam. For you to see the folder, you have to enable “Show Hidden Files” in your window manager.

It is the folder that contains all Manager program files. Your system might show different name I presume.

The folder mentioned above is per session. Meaning whenever you close the program, it will be removed from /tmp folder. Hence the folder tmp for Temporary.

And thanks for pointing out my previous post as it helps to make it clearer instructions for others.
