[SOLVED] Xorg only starts after a wayland session

Hi,

Since a week any Xorg DE/WM (tested KDE plasma5, gnome, i3wm) will not start , but instead freeze my laptop. When starting from a TTY, the freeze happens when the Xorg messages on the TTY are still visible. I cannot change TTYs, nor does my laptop respond to the power button: I have to long-press to force shutdown. REISUB didn't work, maybe because it is not compiled into the default kernel, or because I did something wrong.

However, when I first start Sway (Wayland, works fine), I can then successfully start any X DE/WM. I can do this in a different TTY with Sway still running, or I can close Sway and start a new session in the same TTY.
Xorg will then only freeze immediately after wakeup. At this point I cannot switch TTYs, but I can move the mouse.

The Xorg logs of a successfully started session and a freezing session are identical, except the "Loader magic".
I checked this by removing all timestamps and doing a 'diff' on the two.

Journalctl after login, starting a freezing Xorg session and pressing the power button to force shutdown:

As far as I can see, none of these two help any further. Where can I find logs of what might be happening? Do any of you know what is going on, or what information would you need to find out?

Hardware:
Lenovo Thinkpad L450,
CPU: i5-5200
Intel integrated HD graphics 5500

Thanks!

Although it is strange that this works from after a Wayland start. But maybe the freeze just happens later then. Either way likely to be an iommu issue.

Re: [SOLVED] Xorg only starts after a wayland session

That did it!
I should have seen that, and I had looked at that post even.. Assumed that was part of me pressing the power button.
Thanks a bunch though, that  was way easier than I thought
