This offending package for bug is proving very difficult to pin down. I have tried to sequentially regress all the packages that the recovery kernel boot are likely to use back to their eoan versions on a 20.04 installation. In each case, I reinstalled the kernels afterwards to insure that the initrd.img files were full regenerated and reinstalled. The installed packages from the following have been regression tested...
plymouth busybox udev kmod grub initramfs libklibc and none of these eliminate the breakage in nomodeset under 20.04 on a Mac ROMed GTX680. The only 'workaround' that I have found is to append 'nouveau.modeset=1' after 'nomodeset' in grub's recovery kernel entry. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-meta in Ubuntu. https://bugs.launchpad.net/bugs/1873965 Title: booting into recovery mode hangs under 20.04 Status in linux-meta package in Ubuntu: New Bug description: On a 2008 MacPro with GTX680 under Ubuntu 20.04, selecting the recovery mode from grub hangs on loading of the ramdisk with the Recovery Menu dialog never appearing. This problem doesn't exist for a fresh install of Ubuntu 18.04 updated to the current package updates. In that case, the Recovery Menu appears as expected. This bug in Ubuntu 20.04 was reproduced for both an existing Ubuntu 19.10 installation dist-upgraded to Ubuntu 20.04 as well as for a fresh install of Ubuntu 20.04.
