Thanks.
Comment #36 shows the bug:
DP-2 connected 1600x900+1366+0 (0x95) normal (normal left inverted right
x axis y axis) 798mm x 334mm
Comment #34 does not show the bug:
[ 6.555] (II) modeset(0): Output DP-2 using initial mode 2560x1080
+1366+0
So I wonder if those are from different logins? Either way, when it's
using the wrong mode of 1600x900 it's also showing an EDID which decodes
nicely and includes 2560x1080:

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller (rev 09)
I have a 3rd gen Intel laptop with only Ubuntu 19.10 installed, and a monitor
attached via DisplayPort. The monitor has a native resolution of 2560x1080.
When I power on my laptop, it is seemingly random whether one of the three
following situations occurs.
1. Displays at the proper native resolution of 2560x1080,
2. Displays at 1600x1200 but not let me select a higher resolution in display
settings, or
3. The display will fail to connect and stay blank (when I enter display
settings it will be on "Single Monitor" mode, but from there I can enable Join
Displays and set it to its native resolution).
Please note I selected "I don't know" instead of gdm3 or lightdm since
i've been having this issue since before installing/switching to
lightdm.
Please let me know what additional information I can provide at this time.
