Installation
- Detailed instructions for installing KDEmod are available at the official website: Download KDEMod
Since KDE 4.1 was announced, the KDEmod repository structure changed. Add these entries to pacman.conf, changing i686 to x86_64 as required:
# KDEmod 3 [kdemod-legacy] Server = http://mirror.rit.edu/kdemod/legacy/i686
# KDEmod 4 - latest stable packages [kdemod-core] Server = http://chakra-project.org/repo/core/i686 Server = http://kdemod.iskrembilen.com/core/i686 Server = http://archlinux.puzzle.ch/kdemod/core/i686 Server = ftp://ftp.wh-stuttgart.net/kdemod/core/i686 Server = http://mirror.rit.edu/kdemod/core/i686
# KDEmod 4 - for any stable extra applications [kdemod-extragear] Server = http://chakra-project.org/repo/extragear/i686 Server = http://kdemod.iskrembilen.com/extragear/i686 Server = http://archlinux.puzzle.ch/kdemod/extragear/i686 Server = ftp://ftp.wh-stuttgart.net/kdemod/extragear/i686 Server = http://mirror.rit.edu/kdemod/extragear/i686
# KDEmod 4 - unstable development packages, use at your own risk! [kdemod-playground] Server = http://chakra-project.org/repo/playground/i686 Server = http://kdemod.iskrembilen.com/playground/i686 Server = http://archlinux.puzzle.ch/kdemod/playground/i686 Server = ftp://ftp.wh-stuttgart.net/kdemod/playground/i686 Server = http://mirror.rit.edu/kdemod/playground/i686
Sync the new servers:
# pacman -Sy
Install a minimal KDE4 system:
# pacman -S kdemod-minimal
Alternatively, fetch a richer set of applications:
# pacman -S kdemod
or opt for a fuller set:
# pacman -S kdemod-complete
Uniform look for QT and GTK apps
- Main article: Uniform look for QT and GTK apps
Install kdemod4-gtk-kde4 with:
# pacman -S kdemod-extragear-gtk-qt-engine
Then set gtk's theme in System Settings.
Screensavers
To enable KDE screensavers and xscreensaver, install the packages:
# pacman -S kdemod-kdeartwork xscreensaver
For KDE3:
# pacman -S kdemod3-kdeartwork xscreensaver
Troubleshooting
This section covers basic problems. For more thorough support, see the KDEmod forums.
NVIDIA graphics card KDE 4 performance problems
Because of the poor 2D-performance in the NVIDIA drivers for 8000- and 9000-series cards, it's very important the latest drivers are installed, which have improved a lot after a version jump to 173.14.09.
Also, make sure nvidia-utils is installed.
# pacman -S nvidia-utils
After the driver and its utils package is installed, edit xorg.conf and make the following is added to the Device section:
Option "RenderAccel" "True" Option "TripleBuffer" "True" #Option "BackingStore" "True" # Setting this will currently crash plasma, so comment that out. # Performance has become much better anyways. Option "PixmapCacheSize" "300000" Option "OnDemandVBlankinterrupts" "True"
Save the file and restart X.
In KDE, go to System Settings -> Desktop -> Advanced Options and make sure the next options match:
- Compositing type: OpenGL
- Keep thumbnails of hidden windows up to date: Checked
- OpenGL mode: Texture From Pixmap
- Texture filter: Bilinear
- Direct rendering: Checked
- Use VSync: Checked
Finally, add this command to KDE autostart:
nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1
Video playback issues with KDE 4
With mplayer, and other media player that uses direct rendering, there have been reports of "jerky" video playback. This can be solved by temporarly turning Compositing off while watching video. Before starting the video, press Alt+Shift+F12. After watching the video, press the same combination again to turn Compositing on.
Determine when Compositing is enaled by noticing transparency (or other) effects while moving windows, starting new applications, and so on.
Khotkeys not working
If khotkeys isn't functioning, then:
- open kmenuedit;
- select the aplication recieving the shortcut-key; and
- assign a shortcut.
Shortcuts should now work as expected.
Package management crash
If KDEmod crashes when accessing menus such as:
- System Settings --> Package Management; or
- Shaman--> Tools --> Settings --> Aqpm Databases Configuration;
then it's likely that this problem has to do with rankmirrors, since it appends a comment to the mirrorlist, containing:
#Server list generated by rankmirrors on 2009-09-04
Apparently, even if the word "Server" is commented out, it still causes the applications to crash. The solution is to edit the mirrorlist:
# nano /etc/pacman.d/mirrorlist
and erase the offending line, or chane it from:
#Server list generated by rankmirrors on 2009-09-04
to:
#List generated by rankmirrors on 2009-09-04
