[Bug 1949677] Re: Vendor logo does not display in correct ratio on external monitor as it have different ratio than internal on

[Daniel van Vugt]

I'm not sure this /should/ be fixed.

We don't want Plymouth to drive separate displays differently (unless it
already does?) because that's double the render load, which is too much
for software rendering.

We could implement the fix suggested in comment #12, but upstream might
not like it for good reason. If some user has a monitor accidentally
turned off and plymouth is stuck then they should be able to turn it on
halfway through and plymouth should be outputting to it.

If it was my machine I would just search through the monitor's own OSD
menu and find the setting that enables use of correct aspect ratios for
non-native modes. ;)

Title:
  Vendor logo does not display in correct ratio on external monitor as
  it have different ratio than internal on

Status in OEM Priority Project:
  Confirmed
Status in plymouth package in Ubuntu:
  New

Bug description:
  As Ubuntu boots up, the vendor logo will be retrieved and displayed on
  the monitor.

  Per test, as internal and external monitors have different Wide/Hight
  ratios, Plymouth will use the monitor ratio of the internal monitor,
  and the vendor logo will be displayed on both monitors.

  Some laptops can boot up even as it's the lid is close, and use the
  external monitor, keyboard, and mouse only.

  For that case:

  - internal monitor: off
  - external monitor: display the vendor still in the internal monitor ratio.

  Which is ok but not perfect.
