Created attachment 140872 Xorg 1.20 log
Hey,
I already posted this issue on the arch forums [1] with little success so far.
When I upgraded from xorg-server version 1.19 to 1.20, my external monitors stopped working. No matter whether I attach some monitor to the VGA port (hard-wired to my internal intel card) or to the DP port (hard-wired to my nvidia card), the external screen will just show a scrambled screen in that case. The images get computed correctly, as can be seen from taking snapshots of the screen for example; so its some issue in the output to the monitors.
As suggested in the linked thread, I removed the ddx drivers for nvidia and intel, however the problem persists wit the modesetting drivers.
I attached my xorg sevrer logs. Please let me know, if there is anything else I can provide.
