I wish I could say I knew what I did to fix it, but my video driver is working now (including in Minecraft).
I had managed to get it to fail to run *anything* in a graphical screen, so threw up my hands and uninstalled all the video drivers to start from scratch. So I apt-get-removed everything I could, including alllll the modprobe conf files, rebooted, and... it worked fine.
Probably should have deleted the modprobe bits first off and just let buster load the drivers it wanted.
@cathal That's my guess too. Even an uninstall/reinstall didn't help: deleting the /home/$user/.config/Slack directory just means attempting to start it gets "/home/$silver/https:/app.slack.com/ssb/signin: No such file or directory" so it wasn't carryover from out-of-date config. So clearly it's a handler within buster somewhere... that only seems to affect Slack.
@gamehawk That's pretty bizarre, my mental model only contained the rubbish browser within Electron/Slack, but this sounds way more "exciting".
My, uh, condolences?
I had a similar mystery, somehow my $CC gets set at startup to gcc-4.7 but, uh.. that version is one newer than I can even manually install. Still haven't figured out where that's getting set. Some dbus shenanigans.
