Title:
Vulkan error when using NVIDIA-Prime
Status in NVIDIA Drivers Ubuntu:
New
Status in nvidia-graphics-drivers-390 package in Ubuntu:
Confirmed
Status in nvidia-prime package in Ubuntu:
Confirmed
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
