Title:
[i915] Unable to set Display to max resolution supported by Monitor
and laptop
Status in linux-hwe-5.11 package in Ubuntu:
New
Bug description:
Hi,
my secondary display support 2560*1440 but 'Display' in Ubuntu is
presenting a max resolution of 2048*1080.
The max resolution was working yesterday, I think I performed a update
today and it has stopped working after that.
Thanks,
Jerry,
