Title: Vulkan error when using NVIDIA-Prime Status in NVIDIA Drivers Ubuntu: New Status in nvidia-graphics-drivers-390 package in Ubuntu: New Status in nvidia-prime package in Ubuntu: New Bug description: After installing Ubuntu 18.10 and the Nvidia driver + Vulkan-Utils, switching to NVIDIA and then running vulkaninfo or vulkan-cube works perfectly. But when you reboot and update, then switch to Intel, then back to Nvidia, all Vulkan programs give an "Assertion `!err' failed." Vulkaninfo: ======= Presentable Surfaces: ===================== GPU id : 0 (GeForce GTX 960M) Surface type : VK_KHR_xcb_surface vulkaninfo: /build/vulkan-tools-ZnxIl9/vulkan-tools-1.1.82.0+dfsg1/vulkaninfo/vulkaninfo.c:1253: AppDumpSurfaceFormats: Assertion `!err' failed. Annullato (core dump creato) Vulkancube: vulkan-cube: /build/vulkan-tools-ZnxIl9/vulkan-tools-1.1.82.0+dfsg1/cube/cube.c:3416: demo_init_vk_swapchain: Assertion `!err' failed. Annullato (core dump creato) I still have not found a workaround for that, the only way to get it working again is to reinstall everything. - Install Ubuntu 18.10 - Install proprietary 390 NVIDIA drivers - Switch NVIDIA-Prime to NVIDIA - Testing the vulkan capabilities works - Updating the system then switching to intel - Reboot - Switch to nvida - Now all Vulkan programs when using NVIDIA give that error To manage notifications about this bug go to: https://bugs.launchpad.net/nvidia-drivers-ubuntu/+bug/1800465/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
