Public bug reported:
Now at Ubuntu 18.04.2 LTS, Gnome 3.28.2
Deduction. The user device settings menu for desktop control dual
monitors offer the correct modes available. The Bionic Beaver update
does something different.
Dual monitor configuration (Formerly Primary on Display Port 3840x2160
30Hz, Secondary on HDMI 3840x2160 30Hz on a three video output Intel
HD620) for Cancer Research using LibreOffice Calc across both.
Upgrades permitted manually rather than auto and usually done within a
day. Since five months both monitors were operating HDMI (Display port
not connected, not used) with Primary on HDMI2 and Secondary on HDMI1,
both at 3840x2160 30Hz. Neither monitor is capable of 60Hz at UHD which
is quite alright for office work. When installing such devices,
strictly only the 3840x2160 30Hz mode is available on the settings page.
After the most recent update (7/8th may), the primary screen was blank
on reboot (abnormal) and the secondary screen showed the extended
desktop without menus (as usual). Rebooting to see the primary was
unsuccessful and then the secondary monitor failed completely (confirmed
the next day as graphics card hardware, broken). Cold disconnect of the
secondary (awaiting repair), another boot brought up Primary display
only yet flickering occasionally.
Primary Display. Considering the possibility of error in the graphics
since the update - the Device settings (normal user page) revealed that
the update had changed the output to HDMI 4096 lines (which the PC
monitor can't do and the user can't select - outside specification). I
was in such a hurry to save it also from damage that I put back the
resolution to 3840x2160 30Hz immediately, without looking at which
frequency had been set with the 4096 value. Now on rebooting, the
display settings menu shows appropriately only 3840x2160 30 Hz as
choice. It seems the Bionic Beaver update needed something else and
set 4096 (which the user can't and notwithstanding the original user
configuration).
Secondary Display. I don't know what it set, but it blew the monitor
card. The linux sent either 3840 at 60 Hz or 4096 at any frequency
without negociation, without being able to respect the user settings.
It's also possible that it used a very low resolution for a few seconds
which the secondary monitor can't do either; it's (well, it was) a real
PC monitor with choices of DP or HDMI yet can jump into various modes
(such as 60/75Hz for gamers). After some Ubuntu upgrades in the past
(blank secondary screen), it was necessary to go back into the monitor
menu to switch off again the gamer mode.
Something similar happened in 2017 with Light Ubuntu Update. The
Secondary (very expensive) display making very alarming noises and
staying blank for half a day. Now it's truly broken (I know it's the
driver circuit and which parts). Waiting for repair or replacement, the
system is in use now with the same Primary PC monitor and a UHD
television as secondary to get by.
I worked 20 years on PC systems and monitors (for ship control) and
accept that in the past we nearly always used a simple basic portable
VGA monitor for system upgrades, then reconnected the user's gear later.
I think I'll only do (and postpone) Linux upgrades from now using a
spare single desktop monitor at 1920x1080. That was a very worrying
experience.
