Re: EAC seemingly broken across entire system

https://wiki.archlinux.org/title/Steam/ … _emulation

This is on a wayland session? Does X11 work?

x11 ends up with the same result

edit, forcing opengl emulation causes the game to crash immediately, but it would not have worked anyway as the EAC splash screen exhibits the same behavior of closing almost immediately

Re: EAC seemingly broken across entire system

any clues here?? tried playing Halo Infinite and i'm still getting issues. system is completely up-to-date.

i tried scouring through the proton logs from nightreign and all i see about EAC is that it's using a "syscall workaround" which i assume is normal? i feel like i am out of leads

Re: EAC seemingly broken across entire system

Your problem is this nullptr resolution

There're actually some hits for https://www.google.com/search?q="EAC"+"Unhandled+exception%3A+page+fault+on+read+access+to+0x0000000000000000" but they typically talk about disabling EAC itfp (and then still getting crashes)

Re: EAC seemingly broken across entire system

How exactly did you go about using the patched glibc?
Are you also using it when the game works w/o EAC?

Re: EAC seemingly broken across entire system

i just replaced my glibc package with glibc-eac then rebooted. i used an AUR helper which i assumed would build and onstall it for me. i removed glibc-eac once i found out it still wouldnt work.
