Description
I'm currently stuck while attempting to diagnose why Qt is unable to find a working surface format:
qt.qpa.gl: Requested format before FBConfig/Visual selection: QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize 8, greenBufferSize 8, blueBufferSize 8, alphaBufferSize -1, stencilBufferSize 8, samples
-1, swapBehavior QSurfaceFormat::DoubleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile QSurfaceFormat::NoProfile)
qt.qpa.gl: Available GLX extensions: GLX_EXT_visual_info GLX_EXT_visual_rating GLX_EXT_import_context GLX_SGIX_fbconfig GLX_SGIX_pbuffer GLX_SGI_video_sync GLX_SGI_swap_control GLX_EXT_swap_control GLX_EXT_swap_control_tear GLX_EXT_texture_from_pixmap GLX_EXT_b
uffer_age GLX_ARB_create_context GLX_ARB_create_context_profile GLX_EXT_create_context_es_profile GLX_EXT_create_context_es2_profile GLX_ARB_create_context_no_error GLX_ARB_create_context_robustness GLX_NV_delay_before_swap GLX_EXT_stereo_tree GLX_ARB_context_flush_control GLX_NV_robustness_video_memory_purge GLX_ARB_multisample GLX_NV_float_buffer GLX_ARB_fbconfig_float GLX_EXT_framebuffer_sRGB GLX_NV_copy_image GLX_ARB_get_proc_address

uffer, swapInterval 1, colorSpace QSurfaceFormat::sRGBColorSpace, profile QSurfaceFormat::NoProfile)
Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior
QSurfaceFormat::DoubleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile QSurfaceFormat::NoProfile)
Aborted (core dumped)
The app is a QtQuick application, and I'm not specifying any explicit surface format before calling QWindow::show
All other OpenGL apps on the system work fine. Please advise on a best way to tackle this issue?
