Bug Description

backport upstream commits to precise-updates 2b23074a0c082219fe4490fa05b13a481b34b41e(partial), e89c2d48a991590c18c28ac867ccda67d4425187 and 44d47bbe6fe6ed0c8fc5855c07b2917a38371ae4 to support high resolution for grub terminal.

Upstream bug: https://savannah.gnu.org/bugs/?39682

[Impact]

When entering GRUB menu on a high resolution computer (resolution > 2040), the boot menu has been compressed into a much smaller rectangle in the far left of the display, likely 20% of the screen.

[Test Case]

Press shift if booting as legacy or ESC if booting as EFI to enter GRUB menu on a high resolution computer. See the output of GRUB menu.

[Regression Potential]

The patch mostly changes terminal part of GRUB. So testing should focus on the gfxterm and console output and input.

@Ara,

we tested with Trusty, this issue can not been reproduced. So this does not affect trusty.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Verified with 2560*1440 monitor. Without precise-proposed, grub terminal only shows on almost 1/5 screen. And enable precise-proposed then upgrade, grub terminal can show on the whole screen.
