If you have a GPU hang and reset, X11 isn't going to be any better. There is some WIP to make recovery from GPU hangs more robust. It's not there yet. * https:

Though I'm not sure what's the current status of that is or how actively it's progressing. Hopefully it will turn into something usable, it's important.
- delusional 4y agoI takkede to an X11 dev once about this. I remember him saying that X supports recovering already. The issues was that most compositors and applications did not.
- shmerl 4y agoIn practice you can't recover and need a reboot even if in theory it's possible.
- account42 4y agoGPU recovery did use to work on radeonsi with compositing disabled at some point. Of course you are usually better off rebooting anyways because who knows what state all the million bits of the GPU were left in after a crash that is by definition an unanticipated event.
