Public bug reported:
Ubuntu asked me to install new packages this morning, what I did and after to
restart my laptop.
Since, my main monitor is black but Ubuntu works on my second one.
When I boot, I see the HP logo appearing on my screen before the ubuntu start.
Everything else works fine.
sudo get-edid | parse-edid
This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 1
No EDID on bus 3
No EDID on bus 4
No EDID on bus 5
No EDID on bus 7
2 potential busses found: 2 6
Will scan through until the first EDID is found.
Pass a bus number as an option to this program to go only for that one.
256-byte EDID successfully retrieved from i2c bus 2
Looks like i2c was successful. Have a good day.
