From searching, it seems this has been an issue for a very long time.
Thanks, regards.

$ om-welcome
GBM is not supported with the current configuration. Fallback to Vulkan rendering in Chromium.
Segmentation fault (core dumped)
$ coredumpctl dump om-welcome
No match found.

First guess would be that. Not positive but I suspect this has been reported a number of times. Perhaps people that actually have nVidia crap would have some suggestion?

You could run coredumpctl and see if /usr/bin/om-welcome is listed. If it isn’t then what would anyone work on? Also go to OM-Chat and ask developers what this means GBM is not supported with the current configuration. Fallback to Vulkan rendering in Chromium. The second part about Chromium seems completely irrelevant to me but what do I know? The first part sort of makes me wonder if users with nvidia hardware need to install some vulkan package or if such a package should be in Requires for 'nouveau` driver and maybe the proprietary drivers as well.

Is your hardware supported by the proprietary nvidia driver OM provides?

Oddly I am not showing any open bug reports with the search word “nvidia”.

Edit: To use effectively coredumpctl you would need gdb. Do an internet search of how to do this and/or contact OM devs on OM-Chat.

Hi Ben,

ironically I ran into this problem because I was trying to install the Nvidia driver the “recommended” way :rofl: !

I’ll install Rock on my other desktop which has an AMD video card tomorrow, see if that makes a difference.

As a quick test I booted from both Rock & Rome isos on the same machine.

Welcome fails to start on Rock, but works on Rome!

I’m downloading ALL versions of both Rock & Rome to test, but the download speed is horrendous and will take most of the day to complete.

Here’s some info to go on (…if anyone who is able to help is reading this)

Tried Rock on my AMD desktop and Welcome works perfectly.

Fixed, but not really solved as the .iso file is obviously still effected.

Solution:

I installed nvidia.x86_64 (…and all auto dependencies) with DNFDrake and it solved the problem for me. Welcome now runs perfectly.
