[Bug 560464] Re: "acer-wmi: Unable to detect available WMID devices" on boot

[Markhor]

To all those having troubles with boot splash:
1)follow workaround of the issue 540801: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/540801/comments/2. That is,
sudo su
echo FRAMEBUFFER=y > /etc/initramfs-tools/conf.d/splash
update-initramfs -u
exit

Now you will do get a boot splash, but it is buggy.

2)replace vga16fb with uvesafb. Tested here (Russian): http://habrahabr.ru/blogs/ubuntu/92637. That is,
Open /etc/default/grub, find GRUB_CMDLINE_LINUX_DEFAULT  and change it (replace everywhere 1024x600 with your actual resolution):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset
video=uvesafb:mode_option=1024x600-24,mtrr=3,scroll=ywrap"

Find GRUB_GFXMODE, replace it:

GRUB_GFXMODE=1024x600

Open /etc/initramfs-tools/modules and add:

uvesafb mode_option=1024x600-24 mtrr=3 scroll=ywrap

Now install v86d and update grub:

sudo apt-get install v86d
sudo update-grub

Open /etc/modprobe.d/blacklist-framebuffer.conf and add:

blacklist vga16fb
