Installation Problems

Desktop CD Install

Alternate CD Install

DVD Install

  • Installing from dvd and choosing italian results at the end in a full english installation (other languages may also be affected) #39483

    • Workaround: install manually your own language sudo apt-get install language-support-[lang] kde-i18n-[lang]

Upgrading Problems

  • Upgrading from breezy uninstalls kubuntu-desktop package #39658

    • Workaround: install kubuntu-desktop package after upgrade sudo apt-get install kubuntu-desktop

Post Install Problems

  • CPU Scaling not working #36014

  • Some multimedia keyboard keys may not function, specifically the Raise Volume key #37341

    • Workaround: to enable the raise volume key, run xmodmap -e "keycode 175 ="

  • Using fglrx or ati drivers may cause KDM/xorg to freeze on logout or reboot #30447

    • Workaround: add (uncomment) the line TerminateServer=true to section [X-:*-Core] in /etc/kde3/kdm/kdmrc

  • Using the latest fglrx driver (8.25.18) renders GLX unusable for some Radeon based cards
  • When using some sound cards with an additional usb sound card sometimes the usb sound card will get /dev/dsp0 and get all sounds by default. This was not the case for breezy (or any other distro I stumbled upon) #46996

Installing Software

  • Add/Remove Programs (adept installer) hangs on installation of packages that require confirmations (for example license, like flashplugin-nonfree, sun-java5-*...) #37696

    • Workaround: install packages from command line - i.e. sudo apt-get install or sudo aptitude install

  • Packages installed with Adept may not immediately add icons to the kmenu a#40048

    • Workaround: run kbuildsycoca to regenerate KDE resource cache, OR log out and log back in, OR open the menu editor and click the 'save' button, OR install packages from command line - i.e. sudo apt-get install or sudo aptitude install


  • Konqueror crashing on web pages with Real media streams #31055

    • Workaround: copy fixed profilerc file from the bug attachement to /usr/share/kubuntu-default-settings/kde-profile/default/share/config/profilerc

  • Konqueror as integrated viewer of compressed files doesn't work
    • Workdaround: rm -R /usr/share/kubuntu-default-settings/kde-profile/default/share/mimelnk/application/


  • KDE hooks for xscreensaver-data-extra and xscreensaver-gl-extra are missing #48056

  • kscreensaver-xsavers is installed but xscreensavers from xscreensaver-* packages are missing #49228

    • Workaround: sudo sed -i -e 's/TryExec=xscreensaver//' /usr/share/applnk/System/ScreenSavers/*


  • Printing (CUPS) not working for everyone ( is there a malone report ? if not can we be more specific about what in cups is not working ? did it not automatically setup a printer , did it remove a printer that was automatically setup ? is the cupsd services not starting ? etc etc etc , thanks )
    • Kurt Pfeifle's blog contains a fairly detailed run down of the problems with the Kubuntu Dapper CUPS setup (as he sees it) from which some bug reports may be distilled: Part 1, Part 2, Part 3, Part 3 (Update).

  • Printing problems with Foomatic drivers #42965

    • Workaround: run sudo foomatic-cleanupdrivers


  • The release notes (help:/kubuntu/krelease-notes/index.html) are full of typos ("Recomendations", "regulary", "preditctably", "Ubuquity", "seperate", etc.), read unprofessionally ("Wahoo a sweet new installer is available ...!!!!", "FREE of charge!!!!", etc.), and appear to be confused in other ways (a paragraph for "a sweet new installer" that talks about features in Breezy, and then a separate paragraph for Ubiquity which is the actual new installer). ColinWatson would like this to be reviewed by a good copy-editor and fixed in dapper-updates.

    • Working on fixing the ReleaseNotes both for style and spelling/grammar. Please see JonathanJesse for more information on this.
