Sorry Timo, I had missed your last comment.
It's not a regression. The same thing happens on a 18.04.2 live session.
Please find attached a snapshot of the BIOS screen.
As you can see, there are two options:
- Enable Switchable Graphics (1)
- Discrete Graphics Controller Direct Output Mode (2)
I tried to start the 19.04 beta live USB in the four possible cases,
here are the results:

Title:
Screen is very dark and brightness cannot be adjusted
Status in linux package in Ubuntu:
Confirmed
Bug description:
Device: Dell Precision 7530
In the BIOS, the Switchable Graphics option is deactived, which means only
the nVidia GPU is used.
When booting 19.04 beta live USB, the screen becomes very dark and
brightness cannot be adjusted. (The same issue happens with 18.04.2)
There is only a "nv_backlight" in /sys/class/backlight/ (i.e. no
intel_backlight):
$ ll /sys/class/backlight/
total 0
drwxr-xr-x 2 root root 0 Mar 27 09:36 ./
drwxr-xr-x 74 root root 0 Mar 27 09:28 ../

../../devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0/card0-eDP-1/nv_backlight/
Trying to manually change brightness doesn't do anything:

root@ubuntu:/sys/class/backlight/nv_backlight# echo 50 > brightness
root@ubuntu:/sys/class/backlight/nv_backlight# cat brightness
50
Although the value is changed, the screen brightness doesn't change.
in dmesg, I can see the following:
