Vulkan issues on ubuntu 18.04

[casperionx]

Ok first up, hi all!

Secondly, ubuntu did an update just today and all of a sudden I cant use PPSSPP.
I tried purging the nvidia drivers and updated with the latest 390 series and that has been successful but still no dice.

I get the following message when I try and load it from the command line:

Code:

casperionx@ubuntuhpg:~/Documents/psp$ ./PPSSPPSDL
I: VulkanLoader.cpp:290: Vulkan test instance created successfully.
I: VulkanLoader.cpp:326: Found working Vulkan API!
Vulkan might be available.
I: Config.cpp:488: Longest display side: -1 pixels. Choosing scale 1
55:45:473 Core/Config.cpp:1038 I[LOADER]: Loading controller config: /home/casperionx/.config/ppsspp/PSP/SYSTEM/controls.ini

I changed graphics backend in the ini from 0 to 1 and tried again and got this:

Code:

casperionx@ubuntuhpg:~/Documents/psp$ ./PPSSPPSDL
I: VulkanLoader.cpp:290: Vulkan test instance created successfully.
I: VulkanLoader.cpp:326: Found working Vulkan API!
Vulkan might be available.

Pixels: 960 x 544
Virtual pixels: 960 x 544

I changed it to 2 and got this:

Code:

casperionx@ubuntuhpg:~/Documents/psp$ ./PPSSPPSDL
I: VulkanLoader.cpp:290: Vulkan test instance created successfully.
I: VulkanLoader.cpp:326: Found working Vulkan API!

Im tearing my hair out here...not sure what to do.


Nvidia drivers:

Code:

casperionx@ubuntuhpg:~/Documents/psp$ lsmod | grep nvidia
nvidia_uvm            757760  0
nvidia_drm             40960  2
nvidia_modeset       1110016  17 nvidia_drm
nvidia              14360576  749 nvidia_modeset,nvidia_uvm
drm_kms_helper        172032  1 nvidia_drm
drm                   401408  5 nvidia_drm,drm_kms_helper
ipmi_msghandler        53248  2 nvidia,ipmi_devintf

Not sure what else I can do, yesterday it was working today, I did an update and it no longer works
Any help would be appreciated
