I have FHD modified Lenovo x230. (Details about the mod here https://forum.thinkpads.com/viewtopic.php?f=43&t=122640) Mod creates an actual FHD display connected to DP-3 but also a fantom, "dummy display" LVDS-1 used for brightness control, normally LVDS-1 is connected to laptop screen but not anymore in my case. I had this mod working for a few years now and I have been using it with a previous Elementary OS Loki version without much problems however small modification to it's config files was necessary to allow X11 to use the correct display. As far as I remember this have been done similar to the way described here: https://forum.thinkpads.com/viewtopic.php?f=43&t=122640&p=805876&hilit=X11#p805876
I'm afraid I'm not 100% sure if this was the exact method I've used to achieve this but it's kind of rings the bell for me.
When i decided to install a new version of elementary OS I've completely forgot that this have to be completed to have a fully working system. Unfortunately I went ahead and done it :)
I do have a working OS but just a blank desktop without an easy way to interact with the system as I cannot see plank etc.
I cannot access terminal with Super+T for some reason but I was able to open programs using ALT+F2 and typing program name (this doesn't work for terminal though), this way they do open on the screen I can see. I was trying to diagnose the problem by accessing one of terminal windows using CTRL+ALT+F1 but even when I try to run xrandr it comes back with "Can't open display" so I'm not sure what is going on. I was trying to check for the files mentioned in the post from thinkpads forum but there is no
/etc/X11/xorg.conf.d catalog or
/var/lib/lightdm/.config/monitors.xml files in Hera.
I'm not sure if the current version of Elementary OS is actually still using X11 or maybe it is all Wayland now?
Can anyone please advise me which files would have to be modified to have all the elements mirrored between LVDS-1 and DP-3 as I think this will be the easiest way to have it working again?
Which files both lightdm and panthon are using for monitor settings now?
I would really appreciate any help with this.
