I have verified on Bionic.
I tested the new packages in bionic-propoesed on ThinkPad L15, which
only have one resolution before. And the new packages in focal-proposed
works. The details:
0. the resolution supported, only one: 1920x1080
1. open bionic-proposed channel and 'sudo apt update'.
2. sudo apt-get install xserver-xorg-core-hwe-18.04 xserver-xorg-dev-

Title:
Only timing mode list in EDID supported on continuous freq monitors
Status in HWE Next:
New
Status in X.Org X server:
New

Bug description:
[Impact]
Some new laptop display set EDID continuous freq bit 1.
Then Xorg only uses the timing modes defined in EDID, no other modes are
shown on Xorg.
Upstream Bug:
https://gitlab.freedesktop.org/drm/intel/-/issues/313
Fix of Xorg in merge request:
https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/421
https://cgit.freedesktop.org/xorg/xserver/commit/?id=6a79a737e2c0bc730ee693b4ea4a1530c108be4e
this is required to support new laptop models which use such panels
[Test case]
Test that a proper list of modes is shown with a panel that uses the new EDID.
[Regression potential]
The patch retains the previous code path for setting modes on GTF-able
monitors, and only adds support for non-GTF monitors. So in that sense there
shouldn't be any regression potential, this has been reviewed by an upstream
expert.
