In the meantime I've upgraded to 18.04 Bionic with kernels 4.15.0-55 and
upward (current: 4.15.0-153), including the patched radeon-driver. So
the flickering - problem is solved for me.

A kernel patch that fixes this issue was finally released in May 2019.
It eventually found it's way into Ubuntu 18.04 and later releases. I've
had difficulty checking if it is Ubuntu 16.04.7 or earlier update to
Ubuntu 16.04 but official support for Ubuntu 16.04 ended in April 2021.
Are you
Same laptop, same problems.
Thanks for temporarily fix using xrandr ...; sleep 2; xrandr ...;
Also i have same problem with xubuntu 18.04.

I found a "kind of work-around":
in grafic-mode, switch the mode several times forward and backward,
e.g.:
xrandr --output LVDS --mode 1440x900
sleep 2
xrandr --output LVDS --mode 1680x1050
put the commands into a script, run that script 2 ... 5 times, until the
flickering suddenly stops.
I tried an advice which I found in the internet:
kernel-option: radeon.new_pll=0
But that results in: ... radeon: unknown parameter 'new_pll' ignored
So: my radeon-driver HAS NO new_pll option.

I have an old Acer laptop with Radeon X1600
Boot screen is OK but when Desktop loads, it's totally screwed and smudged. I
kinda see if I can open a window but not usable.

Title:
Ubuntu
I did a test with:
- ubuntu 18.04.1 LTS, all updates installed, kernel 4.15.0.33
-> the screen still flickers ...
meanwhile I use a 'work around':
ubuntu 14.04.05 LTS, kernel 3.13.0-157
-> the screen is o.k. (NO flickering)
BUT: that is not a real solution ...
