The Software Fails to Launch

Upon launching the Logic 2 software, you may experience the following:
An immediate software crash
A blank canvas with an error message that displays Error Connecting to Socket
The terminal displays The display compositor is frequently crashing. Goodbye.
You might also see the following message when running Logic 2 from the terminal. This is normal and is not associated with the issues noted above.
(electron) The default value of app.allowRendererProcessReuse is deprecated, it is currently "false". It will change to be "true" in Electron 9.
We've highlighted some potential causes and solutions below.
We've received reports of some graphics cards causing immediate crashes when launching the Logic 2 software. We're currently logging a list of graphics cards that have been reported to crash the app in the . Based on the list of graphics cards we have gathered, it seems that graphics cards released more than 8 years ago has some issues with running our software, but we don't have conclusive evidence yet.
For now, if you feel your graphics card may be the culprit, you may try the troubleshooting steps in the support article below.
Our list of supported operating systems can be found in the link below. You'll want to ensure you are running a supported version of Ubuntu.
--no-sandboxWhen launching the software from the terminal normally, you may see the following error message.
The display compositor is frequently crashing. Goodbye.
If you see this error message, try launching the software with the --no-sandbox argument as per below.
./Logic --no-sandbox
--disable-gpu or --in-process-gpuTry each one of these command line arguments one at time. We've seen a handful of launch crashes where the Chromium GPU process repeatedly fails to start, causing the app to give up and exit. If you see a console message like "GPU process isn't usable. Goodbye.", this might fix it.
./Logic-2.*-master.AppImage --disable-gpu
./Logic-2.*-master.AppImage --in-process-gpu
If you are attempting to run our Logic 2 software on Linux, take a look at the output of the following commands.
./Logic-2.x.xx-master.AppImage --appimage-extract (replace "x.xx" with the specific version of Logic 2)
cd squashfs-root/resources/linux
ldd libgraph_server_shared.so
ldd -v libgraph_server_shared.so
Open the generated output file and search for a line similar to the following:
libnsl.so.1 => not found
It seems that some Linux distributions may have removed libnsl, and that reinstalling it solves this issue. The command to install it will depend on the package repository for your specific OS. For example, for the yum package manager:
yum install libnsl
Instead, you'll want to install the udev rules file to allow the non-elevated application to work with devices. Instructions for installing the udev rules file can be found in the support article below.
We've seen GPU issues on Linux where the application will crash on launch due to the GPU process repeatedly crashing on launch.
7. On Fedora, try installing libxcrypt-compat
sudo dnf install libxcrypt-compat
8. FUSE issues with Logic 2 on Ubuntu 22.04
We package the Logic 2 software using AppImage, which depends on FUSE 2.x. Ubuntu 22.04 and other recent distributions have removed FUSE 2.x by default, replacing it with FUSE 3.x, which is not compatible with AppImages. We're looking into a simple long term solution, but in the meantime, simply installing FUSE 2.x should solve the problem. For more details and distro-specific instructions, please check the AppImage FUSE install documentation linked below:
9. Contacting Support
Be sure to select the x64 version if you are using a 64-bit version of Windows. After you have installed the runtime, try restarting the computer and running the Logic 2 software again.
The workaround is to take a look at your /etc/hosts file and to check if it contains the following line. If it’s missing, you'll want to add that line back and that should solve the issue.
127.0.0.1 localhost
Starting version v2.3.22, we fixed an issue with the software immediately crashing upon opening on Linux. You can download the latest version of the software .
Although Fedora is not an operating system that we officially support, suggested that running the following command solved the "Error Connecting to Socket" error on Fedora 39.
In case the solutions above don't help, please and send us the output of the commands generated from step 3 above.
For Windows 10, manually installing the helped some users.
On MacOS, you may see the Error Connecting to Socket message when attempting to start the Logic 2 app while disconnected from the internet. This is unintentional, as the app was designed to be able to run while offline. , we've found that localhost may not resolve on your machine when disconnected from the internet.
