How about:

xv -root -random -wait 300 -wloop -ico -vie -fl xv.files &

where: 300 is frequency in seconds that background will change xv.files is a beforehand prepared file with the full path of the images

just put it in the Autostart (KDE.1.1.2) It should work with KDE2 -Stathis.

There is an excellent app named XV on the distribution that will accomodate your need.

Hello all:

KDE 2.0.1 won't accept .jpg files as Wallpaper, but it does accept .png files for this purpose. Can anyone point me to a utilty thtat will do this conversion, or possibly to a library file that is needed by KDE 2?

Or you could use djpeg < file.jpg | pnmtopng > file.png for a once-off conversion. If you do it often (i.e. more than 1.5 times), then create a shell alias, function or script containing the commands as a core. See the respective manual pages for conversion options. -- /"\ Bernd Felsche - Innovative Reckoning, Perth, Western Australia \ / ASCII ribbon campaign | I'm a .signature virus! | X against HTML mail | Copy me into your ~/.signature| / \ and postings | to help me spread! |

Mine does just fine.. Maybe you didn't install everything you need.

I ran into the exact same problem when I upgraded using SuSE KDE2.0 about a month ago. The reason is that your Qt installation doesn't have the jpeg option set.. While mine would display png files, it wouldn't display jpeg or gif files. Check which version of Qt-Free you are running and then go out to the Qt-Free site (use goggle to find it) and download the source for your verison. When you run "./configure" use the following: ./configure -gif -system-libpng -system-libmng -system-jpeg Here is the rest of the Qt install instructions. Substitue your version numbers for the ones listed here, and use the configure arguments I show above.: INSTALLING Qt FOR X11 <p>You may need to be root, depending on the permissions of the directories where you choose to install Qt. <p>1. Unpack the archive if you have not done so already: cd /usr/local gunzip qt-x11-2.2.2.tar.gz # uncompress the archive tar xf qt-x11-2.2.2.tar # unpack it This creates the directory /usr/local/qt-2.2.2 containing the files from the main archive. Rename qt-2.2.2 to qt (or make a symlink): mv qt-2.2.2 qt The rest of this file assumes that Qt is installed in /usr/local/qt. <p>2. Set some environment variables in the file .profile (or .login, depending on your shell) in your home directory. (Create the file if it is not there already.) QTDIR - wherever you installed Qt PATH - to locate the moc program and other Qt tools MANPATH - to access the Qt man pages LD_LIBRARY_PATH - for the shared Qt library This is done like this: In .profile (if your shell is bash, ksh, zsh or sh), add the following lines: QTDIR=/usr/local/qt PATH=$QTDIR/bin:$PATH MANPATH=$QTDIR/doc/man:$MANPATH LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH export QTDIR PATH MANPATH LD_LIBRARY_PATH In .login (in case your shell is csh or tcsh), add the following lines: setenv QTDIR /usr/local/qt setenv PATH $QTDIR/bin:$PATH setenv MANPATH $QTDIR/doc/man:$MANPATH setenv LD_LIBRARY_PATH $QTDIR/lib:$LD_LIBRARY_PATH After you have done this, you will need to login again, or re-source the profile before continuing, so that at least $QTDIR is set. The installation will give an error message and not proceed otherwise. <p>3. Install your license file as $HOME/.qt-license. For the free edition, you do not need a license file. For Professional and Enterprise editions, install your license file as described in your distribution. <p>4. Building. This step compiles the Qt library, and builds the example programs, the tutorial, and the tools (eg. the Designer). Type: ### ./configure ./configure -gif -system-libpng -system-libmng -system-jpeg This will configure the Qt library for your machine. Note that GIF support is turned off by default. Run ./configure -help to get a list of configuration options. Read PLATFORMS for a list of supported platforms. To create the library and compile all examples and the tutorial: make If your platform or compiler is not supported, read PORTING. If it is supported but you have problems, see http://www.trolltech.com/platforms/ <p>5. In very few cases you may need to run /sbin/ldconfig or something similar at this point if you are using shared libraries. If you have problems running the example programs, e.g. messages like can't load library 'libqt.so.2' you probably need to put a reference to the qt library in a configuration file and run /sbin/ldconfig as root on your system. And don't forget to set LD_LIBRARY_PATH as explained in 2) above. <p>6. The online HTML documentation is installed in /usr/local/qt/doc/html/ The main page is /usr/local/qt/doc/html/index.html The man pages are installed in /usr/local/qt/doc/man/ <p><p>That's all.
