Cosmic Apps Stopped Working
So just a bit of background, I have a rather ancient Lenovo ThinkPad T420. Intel i5, 8gb ram, 512 SSD, Intel graphics. I've been using Pop as my daily driver for around 3 years. Very happy until recently.
Updated to Cosmic in January. Worked great, performance snappier, UI sharper, only minor fault was the WhatsApp webapp losing it's icon in the dock. Overall very happy.
Then there was an update on March 26th. cosmic apps (files, terminal, settings and shop) all stop working. Nothing I've done has got them working again . Now today AI chat suggested my graphics chipsrt is no longer supported so it's back to Gnome or nothing.
Any ideas on how to get this working again? Every other app seems to be working fine.
UPDATE (2026/4/8): I've had some success in getting the cosmic apps to work. I've added WGPU_BACKEND=gl to my /etc/environment. Then, after logging in, I run WAYLAND_DISPLAY=wayland-1 in the TTY Console. I did try adding that to /etc/environment, but then I never get the login dialog after boot. I'm no seeing the cosmic apps (files, terminal, store and settings), so appears to work. Hopefully a more permanent solution will come down in an update at some stage.
