What am I missing? I've got Elementary running in Hyper-V, but the only screen resolution available to me is 1152x864.
Of course I figure it out as soon as I post.
For the record, it was adding
video=hyperv_fb:1680x1050 to the
GRUB_CMDLINE_LINUX_DEFAULT line in
update-grub and a reboot.
Doesn't let me change resolution as and when I want, but should be OK for now.
