So I changed FirstVT to 4. This had the undesirable effect of causing GDM to be unresponsive to the keyboard (mouse still worked). Then I changed FirstVT to 5... keyboard now works. And the odd artifacts remained. Did I not make the change you were proposing properly? I don't believe this has any effect. -- Regards, Eric
