The log looks like Wayland sessions are starting up just fine. I wonder if this might be another simpledrm issue (even though simpledrm card0 is clearly already removed before GNOME starts on Intel card1)... Please try adding kernel parameter:

This happens sometimes already on the login screen (mouse pointer frozen, no keyboard input accepted). Sometimes it happens a few seconds or a few minutes after login. No further input possible. No change to a text console possible. When I disconnect the USB-mouse and reconnect it, the mouse LED remains dark. Seems that USB is frozen too. This happens with kernel: vmlinuz-6.8.0-40-generic When I boot the previous kernel: vmlinuz-6.5.0-45-generic, no freezes occur and all works well. I managed to switch to a text console before the freeze happened. The attached files were created in a text console as root and then transferred to a different computer in order to report the bug.
