Troubleshooting Common Installation Issues

Even with careful preparation, you might encounter certain issues when installing Pixeluvo on Linux Mint 22. Here are solutions to the most common problems:

Missing 64-bit Binary Error:
If you receive an error message stating “/opt/pixeluvo/bin/Pixeluvo64: No such file or directory“, this typically indicates an architecture mismatch.

Solution:
Check if you have the correct package for your system architecture:

uname -m
dpkg -l '*pixelu*'

If you’ve installed a 64-bit package on a 32-bit system or vice versa, uninstall it and download the correct version.

Dependency Resolution Failures:
If apt reports unresolvable dependencies:

1. Update your repository information:

   sudo apt update

2. Try installing with automatic dependency resolution:

   sudo apt install ./pixeluvo_1.4.5-1_amd64.deb

Application Launches But Crashes:
This often relates to Qt library conflicts. Try launching with:

LD_LIBRARY_PATH=/opt/pixeluvo/libs64 /opt/pixeluvo/bin/Pixeluvo64

Or for 32-bit systems:

LD_LIBRARY_PATH=/opt/pixeluvo/libs32 /opt/pixeluvo/bin/Pixeluvo32

Installation Seems Successful But Program Won’t Start:
Check the launcher script to ensure it’s correctly identifying your system architecture:

cat /usr/bin/pixeluvo

Fixing the OpenSSL Configuration Issue

A common problem with Pixeluvo on newer Linux distributions, including Linux Mint 22, involves OpenSSL compatibility. The error typically appears as:

pixeluvo: error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No such file or directory

This occurs because Linux Mint 22 uses OpenSSL 3.x, while Pixeluvo was compiled against OpenSSL 1.1.x. Here’s how to fix it:

Temporary Fix:
To test if this is your issue, run:

export OPENSSL_CONF=/dev/null && pixeluvo

If Pixeluvo launches successfully, you can make the fix permanent.

Permanent Fix:

1. Edit the Pixeluvo launcher script:

   sudo nano /usr/bin/pixeluvo

2. Add the following code before the line that runs Pixeluvo (typically before `$BIN “$@”`):

   # OpenSSL 3.x compatibility fix
   if [ -z ${OPENSSL_CONF+x} ]; then
       export OPENSSL_CONF=/dev/null
   fi

3. Save the file (Ctrl+O, then Enter) and exit (Ctrl+X)
4. Make the script executable if needed:

   sudo chmod +x /usr/bin/pixeluvo

5. Test the fix by launching Pixeluvo from the menu or terminal

This modification tells the application to ignore the system’s OpenSSL configuration, allowing Pixeluvo to use its bundled libraries instead.

Advanced Configuration for Performance

Optimize Pixeluvo’s performance on Linux Mint 22 with these advanced configurations:

Memory Allocation:
For systems with 8GB+ RAM, increase Pixeluvo’s memory allocation:

1. Create a custom launcher script:

   sudo nano /usr/local/bin/pixeluvo-enhanced

2. Add the following content:

   #!/bin/bash
   # Increase memory limits for Pixeluvo
   ulimit -v 8388608
   # Launch with environment variables
   OPENSSL_CONF=/dev/null pixeluvo "$@"

3. Make it executable:

   sudo chmod +x /usr/local/bin/pixeluvo-enhanced

4. Create a desktop shortcut that uses this enhanced launcher

Graphics Acceleration:
Enable hardware acceleration by confirming your OpenGL settings:

glxinfo | grep "direct rendering"

If this returns “Yes,” your system supports hardware acceleration. Ensure your graphics drivers are up-to-date for optimal performance.

Workspace Optimization:
Configure Pixeluvo’s workspace for your specific workflow:

1. Launch Pixeluvo
2. Navigate to Edit > Preferences
3. Adjust cache sizes based on your available RAM
4. Configure scratch disk location on your fastest storage device
5. Set an appropriate undo level (15-25 is typically sufficient)

These optimizations ensure Pixeluvo runs efficiently even when working with large files or complex projects.
