ubuntu 启动后登陆老是卡住， dmesg看，有个错误

vmwgfx unsupported hypervisor

The "vmwgfx unsupported hypervisor" error in VirtualBox with Ubuntu usually occurs due to a graphics driver mismatch in Ubuntu 24.04+ with VMSVGA. Fix it by powering off the VM, going to Settings > Display, changing the Graphics Controller to VBoxSVGA, and setting Video Memory to 128 MB

Steps to Fix
Shutdown your Ubuntu Virtual Machine.
Open the Virtual Machine Settings.
Navigate to Display -> Screen tab.
Change the Graphics Controller from VMSVGA to VBoxSVGA.
Increase the Video Memory to 128 MB.
Optional but recommended: Uncheck Enable 3D Acceleration if you still face black screens.
Click OK and restart the VM
