[Bug 1829872] Re: No more desktop effects since libdrm upgrade in Bionic

    No. I noticed it immediately. However, since most of the time fixes come within
    a few days, I did not report the bug at the time, thinking I wasn't the only one
    with that desktop behavior.

    I'm not "blaming" libdrm in a criticizing way :) It's just that it was the ONLY
    updated package at that time that could have caused the bug to appear since I
    doubt libreoffice could be the one that has an impact (see the previous attachment
    with the upgraded packages that day)... As a developper myself (bare-metal, kernel,
    CLI, QT) for the industry, I'm fully aware that there can be bugs at several levels.

> You still have the old libdrm available in the archive btw, does downgrade do anything?

    No in mine, I'm afraid. I tried to do that but apt do not want me to. When I simulate
    the downgrade here is what it gives:

$ cat libdrm2-packages-versions
libdrm-nouveau2=2.4.95-1~18.04.1
libdrm-amdgpu1=2.4.95-1~18.04.1
libdrm2=2.4.95-1~18.04.1
libdrm-intel1=2.4.95-1~18.04.1
libdrm-radeon1=2.4.95-1~18.04.1
libdrm-common=2.4.95-1~18.04.1

$ sudo apt-get -s install $(cat libdrm2-packages-versions)

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gnuplot : Depends: gnuplot-qt but it is not going to be installed or
                    gnuplot-x11 but it is not going to be installed or
                    gnuplot-nox
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

    Trying to upgrade them 1 by 1 gives the results found in this post attached file. I
    did not go further in downgrading in the fear of having inconsistencies between
    packages versions.

Title:
  No more desktop effects since libdrm upgrade in Bionic

Status in libdrm package in Ubuntu:
  Incomplete

Bug description:
  Hello.

  I upgraded my system on 2019-05-09 and since then desktop effects do not work anymore. It installed
  a new libdrm stack :

  $ grep -A 3 "2019-05-09 *08:53:53" /var/log/apt/history.log | tail -n 1 | awk -F "," '{for(i=1;i<=NF;i++){print $i}}' | grep -A1 libdrm

  I have an ATI Radeon that was working fine with KDE until then. I waited to see if someone had realized it before creating a bug report... It really is annoying : no more transparency, no
  more auto-hide of windows : my workflow is strongly impacted.
