| - | == See graphics ==
| + | |
| - | To see graphics, you need to start Xephyr. This example shows how to install and run it on SUSE Linux 11.1.
| + | |
| - | root@i386 $ yast -i xorg-x11-server-extra | + | |
| - | root@i386 $ Xephyr :4 | + | |
| - | Now back in your scratchbox
| + | |
| - | [sbox-DIABLO_ARMEL: ~/qttest] > export DISPLAY=:4 | + | |
| - | [sbox-DIABLO_ARMEL: ~/qttest] > ./qttest | + | |
| - | Now you should see a "hello world" button in a graphical window.

| - | [sbox-DIABLO_ARMEL: ~/qttest] > ./bootstrap && make -j4 && make install | + | |
| - | I ran into [http://www.cmake.org/pipermail/cmake/2009-February/027065.html this issue], so I created link.txt by compiling cmake in a non-scratchbox environment and copying it over.

| - | == gpgme ==
| + | |
| - | gpgme is needed for kdepimlibs.

| - | == checkinstall ==

| - | Checkinstall is needed to build packages that we will copy.
| + | |
| - | wget http://www.asic-linux.com.mx/~izto/checkinstall/files/source/checkinstall-1.6.2.tar.gz
| + | |

| - | == ktimetracker ==
| + | |
| - | As example application that we want to run on the N810, we take ktimetracker from the KDEPIM package. So, checkout kdepim
| + | |
| - | cd
| + | |
| - | svn co https://svn.kde.org/home/kde/branches/KDE/4.1/kdepim
| + | |
| - | cd kdepim
| + | |
| - | cmake . && make
| + | |
| - | This results in an error, however we go on:
| + | |
| - | cd ktimetracker
| + | |
| - | make
| + | |
| - | Now, as checkinstall does not work, we manually put the dependencies into a package:
| + | |
| - | ldd ktimetracker | + | |
| - | Copy all the files into /root/slash on the N810. Copy the file ktimetracker there. Copy the menu file /usr/local/share/apps/ktimetracker/karmui.rc there.
| + | |
| - | | + | |
| - | = back on the N810 =
| + | |
| - | cd /root/slash | + | |
| - | export LD_LIBRARY_PATH=.
| + | |
| - | ./ktimetracker
| + | |

| - | == How to make a screenshot ==
| + | |
| - | Here is how you can trigger a screenshot from command line under maemo:
| + | |
| - | apt-get install graphicsmagick
| + | |
| - | [http://www.man-wiki.net/index.php/1:gm#GM_IMPORT gm import] -window root rootwindow.jpg
| + | |
| - | | + | |
| - | == How to use the SD storage ==
| + | |
| - | If you want to store your KDE executables on the large /media/mmc1, you have to play some tricks. Remember that your N810 cannot format anything as ext2 (let alone ext3 and ext4). So you have to mount your mini SD card as vfat with all permissions set, so that every file is executable:
| + | |
| - | cd
| + | |
| - | umount /media/mmc1
| + | |
| - | mount /dev/mmcblk1p1 /media/mmc1 -t vfat -o umask=000
| + | |
