How do I fix it so that both boots come up hi-res?
That really depends on your firmware setting, I think. Check all options to see if it is possible to allow more video memory by default as when pressing F11.
Not sure I'm totally with the uefi part exactly doing it yet. Uefi could present almost any set of devices but not sure it would select amount of video ram. Guess it could but why would it do it on a F key that should be exactly as normal boot.
I get the feeling that the video is not fully up when it boots normally but I don't know how to prove that.
Might be some command line boot time options to do fix this. Some wait setting for time to settle?
Yes, I am using GRUB. I checked out that link and followed a winding path that led me to discover that I am actually using the Intel HD530 built into the I7 rather than the NVIDIA GTX950M also on board.
Ok, I tried a different distro and it won't even boot with the normal boot sequence, but F11, which brings up the boot selection menu, will let me select the primary drive and boot.
I'm doing some reading on UEFI right now. It's looking like the problem is there. I have two machines that I'm switching distros on and they both have similar issues when it comes to booting.
Does xrandr report the same specs under both boots?
$ xrandr
Code:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192

1280x960 60.00
1280x800 59.91
1152x864 75.00
1280x720 60.00
1024x768 75.03 70.07 60.00

720x400 70.08
VGA-0 disconnected (normal left inverted right x axis y axis)
I'd rather think that what you see comes to the fact that in one case the Intel video chipset is in use, and in the other one it is the NVidia one. Look in the firmware's menu for a setting like integrated video output vs dedicated as usually found in case of hybrid graphics.
It is also possible that in one case only a framebuffer be used.
