I'm having the same issue as described here: my computer won't wake up after I lock the screen or put it to sleep. One of the answers suggests running sudo gdm3 -reset, which I tried. But just as some in the comments noted, I get Failed to parse options: Unknown option -reset.
I thought this deserved its own question. A quick search didn't turn up anything mentioning this specific error, and I don't know enough about gdm3 to troubleshoot this on my own effectively.
Here are the last several lines of sudo strace gdm3 -reset, in case that's helpful:

It seems to be looking for something in that cascade of files (something that defines -reset, perhaps?), and giving up when none of those files exists. Should they?
Any suggestions much appreciated. Thanks!

...and yes, I did put a Christmas tree in my bash prompt.
