Description of problem: I've tried booting Fedora with "nomodeset". GNOME failed to load (in BIOS mode, UEFI worked just fine) on one of two tested (bare metal) desktops. Version-Release number of selected component (if applicable): gdm-3.28.0-6.fc28.x86_64 mesa-dri-drivers-18.0.0-0.3.rc4.fc28.x86_64 How reproducible: Always(?) Steps to Reproduce: 1. Boot Fedora with nomodeset Actual results: After logging in, screen stays with grayish (gdm) background with no content. Expected results: GNOME should work with VESA driver.

I have tested today with the latest build (https://kojipkgs.fedoraproject.org/compose/branched/Fedora-28-20180403.n.0/compose/Everything/x86_64/iso/Fedora-Everything-netinst-x86_64-28-20180403.n.0.iso) and the installation was working on our bare metal. There were some blinking and glitching of the screen, but finally it was able to set up and display everything correctly.
