I did solve it doing:
For 1) is there a way to rescale the KDE resolution so it fits the LCD screen?
1 ) install kubuntu
2 ) update & upgrade kubuntu
3 ) download nvidia proprietary video drivers (the one i'm using is NVIDIA-Linux-x86-256.53.run)
4 ) install lmce
5 ) after reboot, enter single mode and install nvidia proprietary drivers
6 ) reboot and enter audio / video setup
7 ) under osb menu enter KDE
8 ) run nvidia setup (from the proprietary drivers)
9 ) search for overscan ruler
10 ) verify the overscan compensation
11 ) edit the /etc/pluto/X-PostStart.sh
nvidia-settings -a "OverscanCompensation[DFP-0]=64"
nvidia-settings -a "SyncToVBlank=1"
nvidia-settings -a "XVideoTextureSyncToVBlank=1"
nvidia-settings -a "XVideoBlitterSyncToVBlank=1"
where nvidia-settings -a "OverscanCompensation[DFP-0]=64" contains the correct compensation for my lcd tv.
12 ) reboot and see if it's working.
If you already have lmce installed, install the nvidia proprietary drivers and utilities.
For 2) how can i add the N95 orbiter and have the JavaMO being sent to it?
I gave up. Too slow. I'm using an IPAQ as mobile orbiter.
For 3) how can the pixelview remote be recognized by the system
I purchased a PVR-500 and sold my pixelview. pixelview is not recognized, i.e, useable by lmce.
4) how to have all the audio working?
Under kde, konsole, sudo su alsamixer (must be root) and unmute the channels (all).
