Hello Daniel. I've filled two new bugs, which possible related to this one. https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2036160 https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2036159 I identified some new type of behaviors with this problem: * this latest kernel is not always able to print the kernel messages to all three monitors, sometimes I need to restart the OS while booting to see the boot on the screen (noquiet text) * if all three monitors are showing the boot, the login manager not shows the anything on the DP-2-2-2 output, which is connected with a DP-DP cable from the docking station. ** the native HDMI from the notebook and the native HDMI from the docking station works mostly all the time * if all three monitors are showing the boot and the login manager can be seen on all theree monitors, the display manager will show the screen on all three if the $HOME/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml file contains only the displays for that setup ** if some fallback or other displays are in the config file, the DP-2-2-2 output remain black. however xrandr shows that it's configured and used. I can only get this work if I reconnect the DP cable
If works, that it's mostly flawless, but if the kernel boot or login manager or desktop cannot be seen - as I mentioned in the list - only the reconnect works. I hope it helps you to understand this situation better. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-6.2 in Ubuntu. https://bugs.launchpad.net/bugs/2020183 Title: i915 keeps crashing with "pipe state doesn't match!" in verify_crtc_state Status in linux package in Ubuntu: Confirmed Status in linux-hwe-6.2 package in Ubuntu: Confirmed Bug description: I'm using a Docking station with two displays (1 HDMI + 1 DP) and one HDMI to the machine's port.
