DXVK in Lutris broke after upgrade to Ubuntu 20.4
Drak May 24, 2020
Hi,

I recently upgraded from Ubuntu 18.4 to 20.4 which worked fine except the fact that all games in Lutris using DXVK no longer run. They do run when I switch off DXVK in the Runner Configuration.
Vulkan works fine (SOTRT runs fine).
Running a game in Proton also works fine.

I am confused. Everything worked with 18.4 and Wine and Vulkan still seem to work fine.
Any Ideas?

Running with DXVK seems to end in some kind of Null-Pointer:
wine: Unhandled page fault on read access to 00000000 at address 00000000 (thread 0009), starting debugger...
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x00000000).

No.
But interesting. I just checked and DXVK 1.5.1 (the oldest one lutris lets me pick) works. Nothing newer.
Also:
This is true for wine version lutris-fshack-5.0.
With lutris-5.7 every version was broken.
(I did not try other wine versions)

it looks like missing 32bit drivers?

I'm on 20.04 and played Star Citizen last week without issues. However, I upgraded through the 19.x versions.

this must be a lutris problem probably a python issue I'm on kubuntu 20.4... and with Wine I didn't notice any breakage .

I don't use lutris.
Which version of wine do you use, and which version of the vulkan loader?

Wine 5.9 devel . DXVK 1.7.

No, I went through https://github.com/lutris/docs/blob/master/InstallingDrivers.md and https://github.com/lutris/docs/blob/master/WineDependencies.md just to be sure

I reinstalled (for other reasons). Now everything works.
