Public bug reported:
If come here over bug 1895301 "XrandR does not propose 3440x1440 21:9
resolution".
In bug 1895301 sombody wrote "We just need one person experiencing the bug to
open a bug with the relevant system details automatically attached." - so I did.
I have a similar problem with a 21:9 monitor with a resolution of
2560x1080. It's a LG 25UB55-B on a HP docking station A7E32A, DVI output
with adapter to HDMI, HDMI cable and input to the monitor via HDMI.
Laptop is an HP Elitebook 8440p (Intel i5-520 with Intel HD Graphics
(ILK)), internal display with 1366*768 is in use as well.
I had Ubuntu 18.04 LTS before until January this year, with automatic
updates on, so presumably up to date. There it worked fine out of the
box, i.e. since first install I had the full resolution of 21:9 in
2560x1080 on my external monitor.
I didn't change any hardware, just installed Ubuntu 20.04 from DVD, an it
stopped working.
I got only 16:9 with 1920x1080.
I've updated to Ubuntu 20.10, tried Ubuntu 21.04 (from DVD as well), changed
cable and adapter, nothing helped.
Did some reseach with google and found the mentioned bug 1895301. The
workaround worked, I got full resolution of 2560x1080 on the external display.
It is not permanent, so at the moment of filing this bug, I'm still back on the
16:9 with 1920x1080.
