I updated Ubuntu 18.04 LTS to 20.04. LTS last week and now I do have a flicking problem, too. My tower-PC starts OK and then begins to flicker. Flickering gets worse the longer I work on the system.
I don't think that it is a reason for the problems but I removed libomp5 before the update to 20.04 LTS on 18.04 LTS according to the release notes of 20.04 LTS that say that for Ubuntu 18.04 systems with clang-6.0 and pocl-opencl-icd it is not possible for the release upgrader to calculate the upgrade to Ubuntu 20.04 and propose to workaround this by removing clang-6.0 or libomp5.
As jglen490 asked in a similar thread for hardware infos inxi -Fxxx told the following.
Could somebody help?
