Wrong external screen detection after Bionic update
I use a Dell laptop latitude 5590 with Bionic 18.04
I use an external screen to extend my laptop screen. It is a Philips 220E (22") with 1920x1080-60Hz capability.
After update my Bionic OS yesterday (7th jan), this morning (8th jan), the external screen resolution has bad 1024x768 resolution. In Settings/Screens, it show RTK 7 instead Philips Consumer Electronics Company 22"
It is connected to VGA connector but xrandr mention DP-1 connected.
I tried to force 1600x900 or 1920x1080 resolution with xrandr as mention at https://wiki.ubuntu.com/X/Config/Resolution#Adding_undetected_resolutions, but without success, resolution is changing but is still not good.
Note that this screen work fine if I connect to desktop computer, and I connected a Dell 20" screen on my laptop and it is correctly recognized.
