gpu "overlay" mode broken?
zzywysm opened this issue · comments
For a long time I've been using Plasma with "overlay" mode, and apart from the overnight build times, things worked fine. Recently it seems to have broken; my NixOS configuration builds but doesn't boot.
I switched to "replace" and things work fine again.
When I try to boot one of my failing NixOS generations, the error appears to be that weston is crashing with this error:
did not find extension DRI_Mesa version 1\nfailed to bind extensions\n
My current working theory is that this nixpkgs commit for mesa:
NixOS/nixpkgs@4f9b3a7
...combined with recent nixpkgs upgrades/changes to the llvmPackages have caused a version mismatch, which in turn is causing an "explosion" as described in the above commit.
