Aside of the computers I am using for testing of my installer, I use vt only in the time from installation of computers to when I get time to configure/build a new kernel to remove vesa (and vt because it pulls in vesa,ko) from the kernel to make suspend/resume work. So I feel usually in some hurry when I want to get a system up and running.. And then I am not in the mood to bother spending time making vt bug reports. Maybe a reason that many of these bugs are not reported is that I love to use mouse mark/paste in the console, and most of the bugs are related to this. No idea how common it is to use mice in console mode; if it is not common this might be why these bugs are apparently under-reported. Almost all my computers still have CSM support, so I use that, as I do not use Microsoft OSes. When time comes and I have to buy computers that do no longer support CSM, I'll look into the sc source to add a VGA BIOS interrupt call to change from UEFI graphics to text mode at initialization time. This should be sufficient to support sc on UEFI machines. Actually I do not understand why this has not yet been done. Do you think such a patch to make sc work on UEFI systems would be accepted into FreeBSD?
