    KDE 4.5 update gives me a blank screen

    Hi,

    Updated from KDE 4.5 RC1 to KDE 4.5 today. (I disabled the kubuntu beta ppa, and enabled only backports ppa)

    When I logged in after the update, all I see is a blank (black) screen and the mouse cursor. Same issue upon restart too. Can anyone help me fix this?

    Thanks.

    Same here. I tried to rename .kde folder (to .kde_bak) and it did't help.

      amd64 kdebase-workspace packages failed to build, so they are missing in repository and currently building again, so wait for some time. i386 packages are probably ok.

      update: missing packages were successfully built and published in repository, so try upgrade KDE again
      Kubuntu 12.04 64bit

        Just noticed when updating that there were a few new packages (ending in ...~ppa2) for kdebase-workspace packges.

        For cases like these, I also have Gnome installed, so if something happens to Kde (e.g. a bad update), I can still login into Gnome (ewww) and fix it. While Gnomes are ugly, they sometimes can be useful.

          I upgraded again and it successfuly installed kdebase-workspace but I still get the black screen after login.

            Correction:
            It didn't install kdebase-workspace. It only upgraded kdebase-workspace-dbg. I installed kdebase-workspace myself and now it works.

              Unfortunately, I had the same black screen experience, yesterday. I've been in contact with some guys on the #Kubuntu channel on IRC, and, apparently, I was too quick in taking on the upgrade. They say it's always better to wait at least one day...

              Anyway, the upgrade process seemingly removed some important package, which they were unable to identify (probably kubuntu-desktop, as I understood). Riddell and James147 were very kind in assisting me, especially James147, who spent the whole afternoon trying to fix this issue, and had a LOT of patience (thanks again!). I've just asked on the channel whether logs are kept of exchanges, and apparently they are. Yesterday's exchange can be found here: http://irclogs.ubuntu.com/2010/08/10/.

              I must add, though, that James147's procedure didn't get me exactly the same desktop I had before, although in the beginning it appeared so, and it still was functional. After one hour use, it showed various graphic problems, especially in the panel, plasma, and generally desktop effects, which, if turned off, left me with very slow response from windows. Also, login screen appeared after a strange flash of striped colours (no more than 1 second, though). All in all, something wrong must have happened when I kept answering lightheartedly "yes" to those questions about removing, adding, and upgrading packages, in the beginning. So, if your main concern is to get back to a working desktop, James147's procedure may well guide you back there. If you are lucky, you may not end up with the same results I had, and may use your computer as before. If not, you may still save your home with a backup, and restore it later on a clean installation, or a recent full backup (I did just that).

              That's all, I'm afraid this is not the solution you were waiting for, but I wanted to share my experience with you anyway. Good luck!

                Re: KDE 4.5 update gives me a blank screen

                When I booted up my PC again today (first boot after the update yesterday), I noticed that the Kde window manager and the plasma desktop were very unresponsive. Rebooting did nothing to fix that. So I booted again, into Gnome this time, and using Synaptic re-installed the packages kde-window-manager and kde-workspace-bin. When I booted into Kde again after that, things were back to normal with full responsiveness.

                  The first upgrade removed more than kdebase-workspace so I did a "sudo apt-get install kubuntu-desktop". This returned the missing packages.
