I'm running Ubuntu 24.04 LTS on a 2020 MacBook Air with an Intel i3 1000ng4, using the ISO from t2linux.org. It came with GNOME by default, but I decided to try out XFCE as another desktop environment. After installing XFCE, I rebooted and logged in to check it out, but I wasn't a fan, so I switched back to GNOME by selecting the desktop option before logging in. I later uninstalled XFCE with `sudo apt-get purge xubuntu-desktop` and `sudo apt autoremove`, and everything seemed fine. However, when I powered off and turned my laptop back on, it booted into a tty1 terminal instead of the usual desktop. I managed to get the desktop back with `startx`, but it's not quite right. All my applications and wallpaper are there, but it still shows the XFCE default apps and the Xubuntu logo at boot. When I check my desktop environment with `echo $XDG_CURRENT_DESKTOP`, it says GNOME, but it feels off—like I can't open more than one app at a time, and it's limiting my CPU usage to about 15%. What should I do to fix this?

It sounds like your system is a bit confused after the XFCE installation. First, you might want to try reinstalling GNOME again to ensure all necessary packages are intact. You can run `sudo apt-get install --reinstall ubuntu-desktop`. After that, check your display manager settings; it’s possible the session type got mixed up. Also, make sure there are no conflicting services running that could be affecting performance.
You mentioned not having a Timeshift snapshot, which is unfortunate because a rollback would have been the simplest fix. Since you don't have that, another option is to create a new user account to see if the issue persists there. If everything works fine in the new account, there might be something in your original user profile causing the problem.
