I cannot install Kubuntu 13.10 (KDE 4.11.5) on my PC, because of lots of display problems : see the URL as an example. I have a "SyncMaster 203B" screen and a "Nvidia GeForce 7300 GT" graphic card. I have successfully installed Kubuntu 12.04 LTS, then I have upgraded to 12.10 (KDE 4.9.5) without problem. When I try to upgrade to 13.10 (KDE 4.11.5) I have again the same problem. Additional info : I have launched Ubuntu 13.10 (=> with Gnome), and it worked correctly. Reproducible: Always Steps to Reproduce: 1.Boot with the Kubuntu 13.10 installation CD 2.Choose "install Kubuntu" 3. Actual Results: In the first screen of the installation process, try the "select language" menu : it is unusable.
Suspend the compositor (Shift+Alt+F12), run "kcmshell4 kwincompositing" and select "XRender" as "Compositing Type" in the 3rd tab - eventually a lower OpenGL variant might work as well. Alternatively install the nvidia binary driver (304.xxx) - i assume Ubuntu only ships nouveau by default. In any case, please provide the output of qdbus org.kde.kwin /KWin supportInformation ideally with the broken state - "qdbus" might now be "qdbus-qt4" You can do this by delaying the call: sleep10; qdbus org.kde.kwin /KWin supportInformation then resume compositing (Shift+Alt+F12 as well), wait half a minute, suspend the compositor again and have the informtation printed into konsole.
Thank you for your answer. Indeed, everything works OK with "XRender", as well as "OpenGL 1.2". The "qdbus org.kde.kwin /KWin supportInformation" command always returns the following message : qdbus: could not find a Qt installation of ''
> "qdbus" might now be "qdbus-qt4" ;-)
But I get a "qdbus-qt4 : unknown command" :-(
http://packages.ubuntu.com/saucy/qdbus http://packages.ubuntu.com/saucy/qtchooser
I had already both packages, up to date.
Direct binary is (according to the packages) /usr/lib/x86_64-linux-gnu/qt4/bin/qdbus resp. /usr/lib/i386-linux-gnu/qt4/bin/qdbus qdbus from qtchooser should resolve that - file a bug against (k)ubuntu Assuming a 64bit installation: /usr/lib/x86_64-linux-gnu/qt4/bin/qdbus org.kde.kwin /KWin supportInformation
Fine ! The qdbus output is at http://paste.kde.org/pnrnmvbgg I will file a bug against kubuntu. Thank you for your investigation.
FWIW, the way to explicitly call the qt4 qdbus is `QT_SELECT=4 qdbus` (how that is better than a separate binary qdbus-qt4, I do not know :S).

Try to disable the blur effect and set the graphicssystem to "raster" (in "kcmshell4 kwincompositing", 3rd tab)

nouveau issue - it's still rather experimental and doesn't support everything yet. Not much we can do about it.
