@epidiah you could do that. Or you could download the upgraded version on a USB stick, boot to it, and see if your keyboard still works. If so, do the upgrade at your leisure. :)
(What kind of fuckup could disable keyboards on the brand of laptop which is probably the most popular ever with Linux users????)
@epidiah
Oof. Yeah, looks like it's a kernel issue, so probably has people working to solve it. And there does appear to be solutions, but yeah, maybe skip this one and jump to the next release when it comes out.
@epidiah you might just wait a while before applying the upgrade. Ideally, wait until an update says the keyboard issue is fixed.
I use Ubuntu LTS releases, but I don't upgrade til there is a MajorRelease.MinorRelease.1 or MR.mr.2 release when most of the implementation quirks have been identified and resolved (or at least worked around).
