As mentioned in the title. Was upgrading from 17.10. Having this screen flickering.
My GPU is AMD RX480
What I did:
- Search for similar issues for 18.04, can't find any
- Perform fresh install. Still the same.
Please help. It is very annoying. I can't work.

I solved it myself by using
amdgpu.dc=0
as a boot parameter.To do this, edit the file
/etc/default/grub
, for example usingFind the line beginning
GRUB_CMDLINE_LINUX_DEFAULT
and add the textamdgpu.dc=0
between the double quotes (""
). Leave any other parameters as they are. For example, you may end up with a line like this:Save the file and exit, and then run
to write the configuration, and reboot.
