Description Dave Cottlehuber freebsd_committer 2015-09-26 15:02:00 UTC
Booting off FreeBSD-11.0-CURRENT-amd64-20150917-r287930-memstick.img is now successful since fixes from #193745 & #202730, however the screen resolution is awry, filling ~3/4 of the screen only at a very low resolution, almost unreadable.

# uga info
UGA: Protocol not present (error=14)

# gop get
mode 0: 2880x1800x32
framebuffer: address = 90000000
color mask:
R 00ff0000
G 0000ff00
B 000000ff

# gop list
mode 0 as above
but, `mode 2` at loader prompt works fine, switches to a very readable resolution, and uses 100% of the screen. It would be perfect if it were possible to stay in this resolution. From within this mode, `gop list` and `gop get` return the same info as above.

@dch is this fixed with #202288?
Comment 2 Felix 2017-11-13 19:59:33 UTC
sorry, I meant #210382.

The macbook has been repurposed but I can at least confirm that the loader itself hasn't changed - still occupying the middle 3/4 of the screen, same debug info as noted earlier.

Given its got intel GPU inside I will see if I can try a recent 12.0-CURRENT and get different results

(In reply to Dave Cottlehuber from comment #3)

So you mean this is in the loader itself - have you tried `mode 2' at the loader prompt? If not, what's the output of the `mode' command?

finally got my hands on an MBP to check this - 12.0R has addressed this.
