xorg not starting on armv7l

[unformatted]

I'm on RPi4 armv7l and just did a full update (pacman -Syu). Now xorg is not starting anymore. I see that xorg-server package updated yesterday. Just a couple of hours before that I also updated and everything was fine. Luckily I made a backup just before updating today. I've restored the backup because I need to work on this Pi so unfortunately I'm not able to provide more details. I justed wanted to report there's an issue with yesterday's xorg-server update on armv7l.

It seems I didn't update config.txt to use kms. My bad. It seems that the latest xorg only works when kms is enabled in config.txt.

After update my 2 rpi 4's I can no longer startx.
RasbianOS works fine so hardware is good.
It appears it can no longer find the video driver.

The same thing just happened to me.
I updated my Raspberry Pi 400 a few days ago before shutting it down.
I turned it on today and and cant run X. According to the log it can't find a video driver.
Honestly, it's been so long since I set this machine up I don't remember what driver it used.
Tried to update again, also tried reinstalling Xorg packages. No joy...

update config.txt to use kms - no difference
#
Info I have gathered implies the relevant drivers are not in the correct place.

Its to do with kernel 5.10.27-4 as 5.10.27.1 is working

I'm up and running again for now.

Because it was mentioned I downgraded the kernel first just to rule it out. It didn't change anything,
but I didn't really expect it too so I put it back.

According to the log my last -Syu upgraded the following Xorg stuff:

xorg-server-common (1.20.10-3 -> 1.20.11-1)
xorg-server (1.20.10-3 -> 1.20.11-1)
xorg-server-devel (1.20.10-3 -> 1.20.11-1)
xorg-server-xephyr (1.20.10-3 -> 1.20.11-1)
xorg-server-xnest (1.20.10-3 -> 1.20.11-1)
xorg-server-xvfb (1.20.10-3 -> 1.20.11-1)
xorg-xwayland (21.1.0-1 -> 21.1.1-1)

I downgraded them all from pacman's cache and it did the trick. After work I'll try upgrading them
one by one starting with the ones I don't suspect to isolate the culprit.
