X11's dying days mean you'll be forced to switch to Wayland
Briefly

Wayland is gradually replacing X11 as the display server for Linux due to its enhanced performance and security features. GNOME has announced it will disable the X11 session in version 49 and completely eliminate X11 code in version 50. This transition coincides with Ubuntu's 25.10 release, which will run GDM sessions exclusively on Wayland. Discussions among the GNOME Release team indicated that this change aligns with improvements in Linux desktop environments and highlights the momentum towards adopting Wayland.
'On May 6th, we held a meeting among the GNOME Release team. We discussed the X11 session, among other things... it would be a great opportunity to go ahead with it for 49.'
'With Ubuntu 25.10 'Questing Quokka,' we are taking a significant step forward in the evolution of the Ubuntu Desktop by removing the Xorg-based Ubuntu session. Starting with this release, the 'Ubuntu' session in GDM will run exclusively on Wayland.'
