Has anyone installed Ubuntu Server in UEFI mode? Is it intended to work?
See this link to a thread in the Ubuntu Forums,
http://
One of the computers is the Toshiba that I often use for testing, a Toshiba laptop with Intel i5 and Intel 3rd gen core proc graphics controller. It runs the kernel module i915 in Xenial desktop systems. The wifi is RTL8723AE using the kernel module rtl8723ae. (I'm writing this report from Lubuntu Xenial in this computer.)
The graphics and wifi work for me without tweaks with all current Ubuntu versions and flavours is UEFI as well as in BIOS mode.
The other one is a Lenovo X131e with Intel i3 and Intel 2nd gen core proc graphics controller. It runs the kernel module i915 in Xenial desktop systems. The wifi is Broadcom BCM43228 using the kernel module b43.
The graphics works for me without tweaks with all current Ubuntu desktop versions and flavours in UEFI as well as in BIOS mode. The wifi does not create any problems when connected via wired network.
Ubuntu Server amd64 (and its debian installer) works in BIOS mode. But there are problems in UEFI mode. I have tried several 14.04 point versions, 15.10 and Xenial (of course amd64 versions). The computer boots to grub, and the grub menu looks good, but after that the screen cannot display anything but some messy lines. It seems that the graphics driver does not get the correct information to work (which is different from BIOS mode in the same computers). So I cannot see the user dialogue, and cannot run the [debian] installer.
This is for testing purposes and for the future. I can boot these two computers in both BIOS and UEFI mode, but we can expect that computers in the future will not boot in BIOS mode, so we should be prepared not only with the desktop versions and flavours, but also the server and mini versions of Ubuntu.

Fred Palmer, 'oldfred' at the Ubuntu Forums, has tried Ubuntu Server too. He has working graphics in a new desktop computer in UEFI mode. But the debian installer failed to install any files:
'I just tried installing server version in UEFI mode, I had just set up 16.04 desktop on sda, and tried server install to sdb.
It booted and took me all the way to installing software and failed. I could see folders, but no files in folders in new install.'

I would say that the debian installer for Ubuntu Server is either buggy, or it has never been intended to use the Ubuntu Server in UEFI mode.
I think that nobody has really tested Ubuntu Server in UEFI mode, or at least it is not tested enough, and I think that it is time to make it work in UEFI mode now.
