Re: Black Screen with signal after full system upgrade [SOLVED]

The line missed in "pacman -Qikk llvm-libs"

warning: llvm-libs: /usr/lib/libLLVM.so.22.1 (SHA256 checksum mismatch)

For "strace -f -o /tmp/eglinfo.strace eglinfo -B":

Re: Black Screen with signal after full system upgrade [SOLVED]

seems our culprit is /usr/lib/libLLVM.so.22.1
I'm seeing info on overwriting this using pacman, but I'm still a bit green on such things. Found the manpage: https://man.archlinux.org/man/pacman.8.en
Would the --overwrite feature be what I'm looking at with this if this is the sole culprit? Or is there something I should do first?

Re: Black Screen with signal after full system upgrade [SOLVED]

Just re-installing the package should do, you don't even have to overwrite stuff.
Make sure the package has no deviations anymore afterwards and enjoy your GPU?

Re: Black Screen with signal after full system upgrade [SOLVED]

That's it! Looks like I may have to do more re-installs of packages that were affected by it. Looks like Firefox was caught in it too, but that was swiftly resolved. If any more cleanup needs to be done and I run into issues, I'll open it in a new topic elsewhere.

This is [SOLVED]. And thank you very much.
