A few days ago, my layout was stopped after updating my sid. Very annoying but I was too lazy to fix it because I have to separate some 30 sec to rewrite xorg.conf-a 🙂 In general, I rewrote it in advance by using the information from here 😉 In general, the procedure is super simple. I was impressed that I had the following in xorg.conf 2 order

Option         "XkbLayout"             "us,that"
Option         "XkbOptions"            "altwin:super_win"

Probably the problem came from them 🙂 I commented to them that I didn't want to test if they were the problem.
