Prevent kernel from displaying messages until modesetting is ready.

On my HP Probook 4540s as soon as the kernel takes control the display is unreadable with individual pixel lines shifted to the right by a constant number of pixels. This persists until modesetting is completed.

Is there a way of suppressing the kernel from using the screen during this time window? I know about the quiet and nomodeset parametes but these do not do what I want.

Re: Prevent kernel from displaying messages until modesetting is ready.

I had this problem with one laptop and found that setting the grub resolution to the correct size for my diplay fixed it. I added the following line to /etc/default/grub:

GRUB_GFXPAYLOAD=1366x768
