Public bug reported:
After updating my laptop after a long trip. It starts to bootm, then
screen goes black with the mouse pointer hanging over, sddm does not
start.
This symptoms I saw them before and were related to mesa libraries. See
https://bugs.launchpad.net/ubuntu/+source/sddm/+bug/1909171 for details on that.
But the actual problem seems somewhat different this time.
Furthermore dmesg shows:

r300_dri.so is from the package libgl1-mesa-dri
I applied the same workaround I did for the previous time that mesa was
broken: downgrade to previous mesa version.
I went to Ctrl+Alt-F2, logged in and:
**
sudo apt install libglapi-mesa=21.0.3-0ubuntu0.3~20.04.5
libglx-mesa0=21.0.3-0ubuntu0.3~20.04.5
libgl1-mesa-dri=21.0.3-0ubuntu0.3~20.04.5
libegl-mesa0=21.0.3-0ubuntu0.3~20.04.5 libgbm1=21.0.3-0ubuntu0.3~20.04.5
sudo apt-mark hold libglapi-mesa=21.0.3-0ubuntu0.3~20.04.5
libglx-mesa0=21.0.3-0ubuntu0.3~20.04.5
libgl1-mesa-dri=21.0.3-0ubuntu0.3~20.04.5
libegl-mesa0=21.0.3-0ubuntu0.3~20.04.5 libgbm1=21.0.3-0ubuntu0.3~20.04.5
***
Now everything works fine. Other than the mentioned mesa packages
everything else is fully updated.
=== In short something got broken again in mesa 21.2.6, downgrading to
21.0.3 fixes the issue. ===
