Bug Description
Since kernel version 4.3 was added to xenial, I've been unable to boot to a usable desktop when using the default Grub settings. Most, but not all, of the screen is covered with an overlay, shown in the attached screenshot.
When experimenting with a fresh install, I discovered that the same thing happens even with a command-line-only system, before X is installed.
Hardware: Asus EeePC 900
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 04) (prog-if 00 [VGA controller])
00:02.1 Display controller [0380]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2792] (rev 04)
The workaround is to remove the line:
gfxmode $linux_gfx_mode
from Grub.
For the moment, I've changed /etc/grub.
$gfxpayload_
so that the change holds after update-grub is run.
The daily live ISO (I've tested with Xubuntu only) boots to a normal desktop.
