Public bug reported:
Ubuntu 26.04 Desktop live USB cannot reach the "Try or Install Ubuntu"
environment on a system with an NVIDIA GeForce RTX 5060.
Steps to reproduce:
1. Create a bootable USB from the Ubuntu 26.04 Desktop AMD64 ISO.
2. Boot the USB in UEFI mode.
3. Select "Try or Install Ubuntu".
4. The system displays the Ubuntu logo and then hangs or shows a black screen.
Expected result:
The live desktop and installer should start normally, or GRUB should provide
an accessible "Safe graphics" option.
Actual result:
The live environment cannot start with the default kernel parameters.
Editing the GRUB entry and adding "nomodeset" allows the live environment
to boot.
Additional information:
- GPU: NVIDIA GB206 [GeForce RTX 5060], PCI ID 10de:2d05
- Ubuntu kernel: 7.0.0-14-generic
- After installation, ubuntu-drivers recommends nvidia-driver-595-open.
- Installing nvidia-driver-595-open allows the installed system to use the GPU.
- The problem occurs before the installer can offer third-party NVIDIA drivers.
