Raspberry Pi findings

I have had the opportunity to play around a bit with a Raspberry Pi lately. Here follows a few findings that perhaps can be helpful to someone.

Composite Video
The Raspberry Pi supports Composite Video. I failed to make the installer display anything at all using Composite Video, for Rasbian and Noobs. With Noobs, I know that it started and did something (becuase the SD card partitions were changed), but I dont know exactly what. With Rasbian, I dont know if I just failed to produce a bootable SD card.

Raspbmc worked perfectly over Composite Video though! So even if Raspbmc was not my first choice, it ended up being what I first played on with.

HDMI Video
I tried the Raspberry Pi Thin Client Project. Works perfectly on HDMI->DVI@1600×1200. So I guess most DVI displays can work fine with an HDMI->DVI-cable.

Raspbmc

  • You can disable XMBC editing startup conditions in /etc/init/xbmc.conf
  • Raspbmc comes with a firewall setting that blocks incoming traffic from outside its own subnet. You can fix this with iptables -F, or for more persistant change, edit /etc/???
  • Static IP is easiest configured via XBMC… /etc/network/interfaces does not seem to work properly, but perhaps my mistake

Raspberry Pi Think Client Project
Where I work, the Citrix Receiver (12.2.3) that comes with RPi-TC, does not work. Applications crashes (The X Request 62.0 caused error:…) quickly. However, I installed 13.0 from Citrix, and opened the Citrix Applications via the web browser – that works fine. But wfcmgr seems missing from 13.0 – I havnt found out what replaces it.

RPi-TC is slow – at the point of being unusuable for anything real. Except for the Citrix client and Remoted desktop client – those work quite fine, and that was the point anyway! Iceweasel is slow. I thought about installing Chromium, but no immediate success with that. Perhaps it is my memory card that is slow.

Noobs / Raspbian
When creating a memory card for Noobs in Linux:

  • fdisk: create one big partition with partition type “c”
  • mkfs.vfat: no need to use any arguments/flags except /dev/mmcblk0p1 (or whatever is your memory card)

With an HDMI cable Noobs and Raspbian works well. Now that I have seen Noobs that is what I recommend anyone to try first. And Raspbian seems fine.

For use as a desktop computer, the Raspberry Pi is in need of an accelerated X server – which will come, perhaps not in the form of an X server at all, but Wayland/Weston. You can try Weston in the latest/current Raspbian, but you can only run a terminal application (unless I have failed to understand something here). It looks very promising, but not useful for anything real at the moment. There is an fb-turbo-Xserver that is now standard, and it is a bit better than the old fb-Xserver that I used when this post was originally written.
