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: [...] Aug 10 21:11:25 xvii kernel: [235310.726023] iwlwifi 0000:0c:00.0: RF_KILL bit toggled to enable radio.
