To get it "working" on 6.7.2, I unintentionally made vulkan unable to load the required drivers. I tried to isolate its drivers to the ones used for my igpu by editing /etc/environment to include `VK_DRIVER_FILES=/usr/share/vulkan/icd.d/intel_icd.json` ...but this breaks vulkan entirely on the system. Running nvidia-smi with this change reveals kwin doesn't run on the dgpu, at the cost of no vulkan on the system. This result is identical to setting `KWIN_DISABLE_VULKAN=1`. Editing /etc/environment to include `VK_DRIVER_FILES=/usr/share/vulkan/icd.d/intel_icd.json:/usr/share/vulkan/icd.d/nvidia_icd.json` (or removing this entire line) resolves all vulkan issues, but once again kwin is running on the dgpu with this. I have my display connected through the DP on the motherboard, so kwin utilizing my dgpu instead of igpu with seemingly no way to configure this is causing noticable UI lag on the kde desktop when running on the power save profile. -- You are receiving this mail because: You are watching all bug changes.
