Bug Description
Hello !
I have 2 monitors
1) one is 4K
2) another one is FULLHD,
when I installed lubuntu I had 4k monitor work at maximum 4k and another at fullhd , I want to change that 4k monitor to 2560x1440(2k).
after install nvidia drivers there is no 2560x1440 resolution in "monitor settings" resolutions tab like it was before installing drivers. when trying to add it manually from xrandr, at some point it gives me that error:
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 16 (RRCreateMode)
Serial number of failed request: 35
Current serial number in output stream: 35
in short , I can't set monitor to 2560x1440. what it might be ?
-------
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description: Ubuntu Hirsute Hippo (development branch)
Release: 21.04
2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
Unable to locate package pkgname
3) What you expected to happen
have 2560x1440 resolution option after installing nvidia driver
4) What happened instead
have no 2560x1440 listed in "monitor settings" and can't even create it manually from xrandr commands
Best Regard !

It appears 2560x1440 was a fake mode created by the open source driver. It's not a mode that is officially supported by the monitor itself, whose data I have decoded below:
