Force VESA driver in Ubuntu 16.10

Question

My Ubuntu 16.10 uses i915 driver. For some reasons I have troubles with it. So I want to force X to use VESA.

I tried:

blacklist i915 in /etc/modprobe.d/blacklist.conf. Then sudo update-initramfs -u. Doesn't work.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash modprobe.blacklist=i915" in /etc/default/grub. Then update-grub2. Doesn't work

Added new file 20-foo.conf in /usr/etc/X11/xorg.conf.d with content:

Section "Device"
    Identifier      "Configured Video Device"
    Driver          "vesa"
EndSection

Doesn't work.

Guys, how on the Earth one could make an OS that requires such an effort just to switch video driver? Maybe I'm doing something wrong?

Try adding "sisfb" to the /etc/modules file, or even renaming/moving all xorg-related config files. — negusp, Nov 15 '16 at 3:11
Didn't work. Also tried to add vesa. Moving xorg.conf.d caused X to not work at all. — user1748526, Nov 15 '16 at 12:37

I had the same issue with a different card and Ubuntu 16.04.

I had luck appending a kernel parameter at boot: vga=791

The vga parameter sets the framebuffer to VESA mode 791 (1024x768 16bit).

To add kernel parameters: this answer or the wiki.
