Hi, Thanks for your reply! I must apologize for the late answer, it seems gmail filtered the mail.
I previously had set CHROMIUM_FLAGS in /etc/environment. These used to work for me: CHROMIUM_FLAGS="--enable-features=UseOzonePlatform --ozone-platform=wayland" I removed chromium and did dpkg --purge chromium, so the /etc/chromium directory was gone and moved my ~/.config/chromium directory away. I tried the three commands: Wayland doesn't work: chromium --ozone-platform=wayland [8051:8051:0315/214032.418318:ERROR:cursor_loader.cc(116)] Failed to load a platform cursor of type kNull [8097:8097:0315/214032.422594:ERROR:gpu_init.cc(440)] Passthrough is not supported, GL is egl, ANGLE is [8097:8097:0315/214032.425174:ERROR:sandbox_linux.cc(377)] InitializeSandbox() called with multiple threads in process gpu-process.

Probably I forgot to clear something, or the reinstall did something.
