I need to be able to see the same screen in VNC as on the screen and as far as I know Wayland does not support this.

So I went to Xorg. Now I am having an issue with the display only being 640x480

When I run xrandr I get as follows.

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 640 x 480, maximum 640 x 480
default connected 640x480+0+0 0mm x 0mm
640x480 73.00*

Is there an easy fix for this?

I saw elsewhere that the i915 does not like the nomodeset flag so I copied the line in /etc/default/grub commented out the original and removed nomodeset from the active line. Then ran
"grub2-mkconfig -o /boot/grub2/grub.cfg"
then rebooted but no luck

To sum up.
It was the nomodeset flag I just was not updating grub correctly.
my /etc/default/grub looks as follows

GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
#GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora00/root rd.md.uuid=c449cef5:b0e299dd:028e55af:fa683980 rd.md.uuid=9e9d3e25:0a50591a:e2541589:55d13aab rd.lvm.lv=fedora00/swap nomodeset rhgb quiet"
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora00/root rd.md.uuid=c449cef5:b0e299dd:028e55af:fa683980 rd.md.uuid=9e9d3e25:0a50591a:e2541589:55d13aab rd.lvm.lv=fedora00/swap rhgb quiet"

If you use EFI you need to use

grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

to update grub
