After having totally networked my home (and after being totally fluent in Android programming), I think this hobby robot platform (TurtleBot) might be just the right thing. They call it “apps on wheels” – sounds like good fun! Have a look yourself:

Reviving Thinkpad X24 with Xubuntu and GLX-Dock

On my experiment turning an old Thinkpad X24 notebook in a nice internet tablet, I have tried out several things. I have still in mind running in the end Android on this device, but I need more time to understand how the Android X86 system works. At the moment it runs in Vesa mode, but this is too sluggish for real use. There seem to be some issues with the radeon module. As an intermediate solution, I decided to use Xubuntu which installed nicely without hassle. I have new fancy very small wlan usb stick (rtl8192cu). This made a little trouble until I tired to compile the drivers available on the cd shipping with it, which worked perfectly with the standard Ubuntu kernel. I had more trouble with suspending the machine. Also here, the radeon module seems to make trouble. After a long search, I found the very simple solution: add radeon.modeset=0 to the kernel command line in grub (edit /etc/default/grub, run update-grub) and install uswsusp. This disbaled the mode switching in the radeon module and now I can suspend – cool! USWSuspend worked a bit better with my wifi and bluetooth driver. I also added the bluetooth-quirk to as extra parameter /etc/pm/config.d/99myown. The file contains now the following: # my own configs for this here [ulno] SLEEP_MODULE=uswsusp ADD_PARAMETERS="--quirk-bluetooth-service-off"
