Lancelot launcher is using anything between 20 and 80% cpu while idling until it is manually killed. This appeared after upgrade to KDE 4.2.1/Qt-4.5 a couple of days ago. I don't know whether this is just the same as https://bugs.gentoo.org/show_bug.cgi?id=258758, maybe the patch therein has not actually made it upstream. At least two other users have noted this on the forum. In addition to the high cpu usage, now Lancelot does not enter into the Application folders when a folder is clicked on. I don't know whether this is part of the same issue.

(In reply to comment #1) > duplicate of 258758 > Not a duplicate. This is about kdeplasma-addons-4.2.1 Back at my Gentoo box now, I've added the lancelot-qt45 patch to the 4.2.1 ebuild, it applies cleanly and builds fine (? - well, it builds), but does not fix either problem. Still high CPU usage (over 90% at times), and clicking on a folder (e.g. Utilities) in the Applications menu does not 'advance' to that folder. What does happen though is that the icon for the folder you want to access appears in the top left hand corner of the Lancelot window, just beneath the 'Search' box. I noticed during build a lot of output like this - ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:windowFlags ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:windowTitle ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:group ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:name ---------- : return buttonLancelotContext ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:group ---------- : return LancelotContext ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:icon ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:name ---------- : return buttonLancelotContext ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:icon ---------- : return lancelot ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:iconSize ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:name ---------- : return buttonLancelotContext ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:iconSize ---------- : return 24, 24 ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:title ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:description ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:innerOrientation ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:extenderPosition ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:name ---------- : return buttonLancelotContext ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:extenderPosition ---------- : return Bottom ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:activationMethod ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:name ---------- : return buttonLancelotContext ---------- : Lancelot::ExtenderButton retrieves attribute Lancelot__ExtenderButton:activationMethod ---------- : return Extender ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:checkable ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:checked ---------- : Lancelot::ExtenderButton wants attribute Lancelot__ExtenderButton:down [ 69%] Generating screensaver_interface.cpp, screensaver_interface.h There was more preceding that, but lost in the konsole. I could increase the number of scrollback lines and post the full output if required.
Scratch my previous post, the patch does work (and solves both issues) - killing just Lancelot wasn't enough, I had to restart X and now it is behaving correctly. So the qt45 patch needs to be applied to kdeplasma-addons-4.2.1
I used to suffer from this bug. Applying /usr/portage/kde-base/kdeplasma-addons/files/lancelot-qt45.patch to kde-base/kdeplasma-addons-4.2.1 seems to have resolved the issue. emerge --info follows: ********************** Portage 2.1.6.7 (default/linux/x86/2008.0, gcc-4.3.3, glibc-2.9_p20081201-r2, 2.6.28-tuxonice-r3 i686) ================================================================= System uname: Linux-2.6.28-tuxonice-r3-i686-Intel-R-_Core-TM-_Duo_CPU_L2400_@_1.66GHz-with-glibc2.0 Timestamp of tree: Fri, 06 Mar 2009 06:00:02 +0000 app-shells/bash: 3.2_p48-r1 dev-java/java-config: 1.3.7-r1, 2.1.7 dev-lang/python: 2.4.4-r15, 2.5.4-r2 dev-python/pycrypto: 2.0.1-r6 dev-util/cmake: 2.6.3 sys-apps/baselayout: 2.0.0 sys-apps/openrc: 0.4.3-r1 sys-apps/sandbox: 1.3.8 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.19.1 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.28-r1 ACCEPT_KEYWORDS="x86 ~x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=prescott -pipe -ggdb" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/config /var/bind /var/lib/hsqldb" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-O2 -march=prescott -pipe -ggdb" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks fixpackages parallel-fetch protect-owned sandbox sfperms splitdebug strict unmerge-orphans userfetch userpriv usersandbox" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LANG="en_US.UTF-8" LC_ALL="en_US.UTF-8" LDFLAGS="-Wl,-O1" MAKEOPTS="-l 4.0" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X acl acpi alsa avahi bash-completion berkdb bzip2 caps cdr cli cracklib crypt cups dbus dri dvd ffmpeg flac fortran gdbm gnutls gpm gtk hal iconv ieee1394 inotify ipv6 isdnlog java jpeg kde kerberos lame ldap mad matroska midi mmx mp3 mudflap mysql ncurses nls nptl nptlonly offensive ogg opengl openmp pam pcmcia pcre perl png postgres pppd pulseaudio python qt qt3 qt4 readline reflection samba sasl sdl session slp sndfile speex spell spl sse sse2 sse3 ssl svg sysfs tcpd theora tiff truetype unicode usb v4l2 vim-syntax vorbis wifi win32codecs wireless x86 xinerama xorg xv xvid zeroconf zlib" ALSA_CARDS="hda-intel usb-audio" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" ELIBC="glibc" INPUT_DEVICES="keyboard mouse evdev wacom synaptics spaceorb" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" USERLAND="GNU" VIDEO_CARDS="intel i810" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, LINGUAS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
Can someone post an ebuild on this? THANKS!
(In reply to comment #6) > Can someone post an ebuild on this? THANKS! > After the RDEPEND section and before the src_prepare section, insert - PATCHES=( "${FILESDIR}/lancelot-qt45.patch" ) Save the changes, and run ebuild kdeplasma-addons-4.2.1.ebuild manifest and then emerge -1 kdeplasma-addons
Thanks, fixed in tree and overlay.
