Public bug reported:
I often connect an external monitor to my laptop and, when I do, I use it as
the only screen, with the built-in display turned off.
This is the configuration I manually set a long time ago, and there was a time
when, by plugging in the screen, or bootin with the screen already connected,
it would automatically switch to this configuration, as one would expect.
Then Ubuntu fucked things up as it usually do at every update, so the behavior
when plugging in the screen or booting became utterly random, but until now, I
would always be able to switch screen configurations with the hardware keyboard
shortcut (on my laptop it's fn+F6) until I get the desired one (built-in screen
turned off, external screen as the only one). Actually there's usually an
interval of time while the system is finishing the boot process (which takes
several minutes because, you know, Ubuntu) during which the hardware
switch-screen key wouldn't work properly, just switching the built-in screen on
and off (immediately) without properly switching configurations. But then, when
everything is up and running, it would start working as expected properly
switching among different screen configurations (only built-in;
builtin+external in extended desktop; mirrored; external only)... except that
it would frantically switch several times for all the times you had been trying
while finishing booting. That makes me think that the keyboard shortcut is
handled by hardware and is just a hard on-off switch for the builtin display
until something in the OS is up and running and starts handling it.
Now, this was the usual behavior until now. It's pathetic in may ways,
but that's not the bug I'm reporting.
Now instead, after completing the boot, the screens came up as mirrored, and
the hardware switch-screens key wouldn't work (it would just turn the builtin
screen on and off while leaving the external screen at the same shitty
resolution as a mirror of the builtin one), just like it usually happens for
the first few minutes, except this time it kept (not)working this way.
I had to manually go to Display settings, turn off mirror mode, switch the
builtin screen off, AND adjust the external screen resolution to a non-idiotic
value.
And the hardware key still does nothing (not even turn on and off the builtin
screen which remains off).
I don't know if this issue will disappear at the next boot. I'm quite confident
that it will, but that doesn't make the issue any less of a bug.
