1) Description: Ubuntu 20.04.3 LTS
Release: 20.04
2) N: Unable to locate package pkgname
3) My current issue is the external display not being detected, but I
don't know how it will behave, given the different issues, at different
boots, being that the repairs/updates from the recovery session may have
changed something, don't know.
The timeline regarding the issue(s):
My laptop screen started showing what looked like a broken screen when
after booting, while on the log in screen (I could not see it). I shut
down and the started again, entered recovery mode (the newer version),
chose to recover, went to boot, after login saw the same broken screen
on the laptop and nothing on the external.
Shut down, start, and back to login screen, rebooted from there (as per
instructed somewhere along the process, don't remember where, something
like "if you can't go in, reboot from login menu").This time the laptop
screen remained unusable but was working on the external monitor. Had
the laptop working for hours and then it froze.
Shut down, start and the same thing, broken laptop screen, this time no
external monitor recognized, as before.
Shut down, start and now, for the first time the laptop screen works but
the external monitor is not recognized. Changing the hdmi cable from a
usb-c hub to the hdmi port, the screen brightness got a lot dimmer, but
nothing on the settings->display menu.
My current issue is the external display not being detected, but I don't
know how it will behave, given the different issues, at different boots,
being that the repairs/updates from the recovery session may have
changed something, don't know.
4) External monitor recognized and working
