A few hours ago, as I did a suspend/resume of my laptop, with only
its builtin keyboard, I noticed that the XKB settings were restored
(without the need to run xkbcomp), and everything worked fine.
I looked at the kernel and Xorg logs (see below), and saw that the
builtin keyboard was recognized as a USB HID keyboard instead of an
AT Translated Set 2 keyboard as usual. But I've done other tests and
I can't make it work again.
USB keyboard recognition needs the RF_KILL bit to be set to enable
radio. I don't know whether this is a bug or there is a reason.
But the bug (XKB settings lost after suspend) needs to be fixed
one way or another. Since the problem may come from the kernel in
the first place, this could be a kernel bug, the problem in Xorg
being just a consequence.
Here are the logs, when the XKB settings were restored:
In the /var/log/syslog file, keyboard information did not appear after
wake up, until the RF_KILL bit was toggled to enable radio:
