Bug ID: 475940 Summary: QTWayland bug yet solved in Qt 6.3.0 for X11 Classification: Plasma Product: plasma-wayland-protocols Version: 1.10.0 Platform: openSUSE OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: rafael.linux.u...@gmail.com CC: aleix...@kde.org Target Milestone: --- SUMMARY There is a QTWayland that has been solved in Qt 6.3.0 for X11. Is related to how QTWayland works in some distros when looking for "libvulkan.so" library. Some Linux distros, like openSUSE or Fedora, name that library as "libvulkan.so.1", so is not find by QT. Issue is identified and solved here https://github.com/qt/qtbase/commit/888b75aa12e2cf35ee760bcf5cb1ed60fe0c0770 too and could be applied easily to Qt 5.15.x. Please fix it ASAP, cause many users have issues in applications under Wayland when their distros have not "libvulkan.so" but "libvulkan.so.1" and it's really a headache for programmers to detect what's happening. Thank you STEPS TO REPRODUCE 1. Launch an application installed from some distros repositories that needs "libvulkan.so" OBSERVED RESULT Usually, at console, application will show some message similar to: initInstance: No Vulkan library available Failed to create platform Vulkan instance despite, in fact, Vulkan related packages are installed EXPECTED RESULT To search for "libvulkan.so.1" too and do not fail SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20231016 KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.110.0 Qt Version: 5.15.11 Kernel Version: 6.5.6-1-default (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 3900X 12-Core Processor Memory: 31.2 GiB of RAM Graphics Processor: AMD Radeon Graphics Product Name: B550M Phantom Gaming 4 ADDITIONAL INFORMATION As a workaround, if user guess that this is the issue he has, he can launch application preceding it with this environment parameter: QT_VULKAN_LIB=/path/to/libvulkan.so.1 name_of_application_needing_libvulkan.so -- You are receiving this mail because: You are watching all bug changes.
