I have put in some of my thoughts and ideas into the wiki : http://wiki.sugarlabs.org/go/Features/Onscreen_Keyboard Thanks, that's a good set of notes. I'll add some of my scrawl to the talk page. FWIW: My iPad testing using RDP has only been partially successful so far. Have been using the iTap RDP client to connect to the Virtual Box built in RDP support: Pros: Pretty fast for a remote session; no redraw or graphics issues; can run the VM headless from the host; sound is remotely relayed (half second delay so not too great for UI feedback testing); uses 100% fullscreen so a 1024x768 Sugar VM looks great on an iPad (iTap uses three finger gestures to invoke its local onscreen controls so you can pretend they don't exist). Cons: Mouse cursor for clicks are not aligned correctly most of the time (still trying to track this issue down, may be client vs. host pointer related); due to the cursor alignment issues you need to invoke a hold gesture to drag the visible cursor to where you want to make a click (slow and defeats the goal of touch screen testing); iPad main virtual keyboard not correctly communicating with the VM (all the custom iTap keys work, esc, function keys, ctrl, alt, cursors etc, but the main keyboard letters do not get through) — which makes using your fvkbd image a must have ;) Regards, --Gary Thanks, Sayamindu -- Sayamindu Dasgupta [http://sayamindu.randomink.org/ramblings] ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Dismissing the keyboard overlay when a text field is defocused would also be ideal. AFAIK, this requires a GTK+ module to be loaded. I'm still trying to write a proof of concept implementation of this - it seems that there's no documentation anywhere for writing GTK+ modules :-( Yeah, I gave up and just used LD_PRELOAD when I had this problem. If you want to try the quick-and-dirty way for a proof of concept, this might be handy: http://dev.laptop.org/git/users/cscott/journal2/tree/ Do all of firefox/xulrunner/chrome use GTK widgets for text entry? I'm nervous that some programs might not pop up the keyboard appropriately. You could add a gesture to force the keyboard up even for badly behaved applications. I think the iPad/iPhone gesture for that is dragging your finger from the bottom of the screen to the top. FWIW: There is no global system gesture or button on the iPad for revealing the virtual keyboard. Selecting any text widget will reveal it; app developers can programatically reveal it (say if they have a custom canvas, our Labyrinth activity would fall in this category); a few individual apps from 3rd parties (none I can see from Apple) have added their own floating semi transparent keyboard icon usually in the far lower right screen corner, in one case (a text chat app) this just seems like poor design, in the others I can remember it's for cases where there is no sane way to know if the keyboard is needed (VNC, RDP clients). There are no keyboard only iOS devices, and all app developers knew from day 1 that devices were touch only, so we are in a slightly different position with needing to support both key and keyless devices, and activities that were written without touch input in mind... So I'm sure we will need a fallback button. Sayamindu device frame seems a good choice, once we have a touch gesture to reveal the frame that is ;) Anyone know what the planned physical buttons may be for the XO-3? If Sugar was native on iPad hardware, I'd certainly want the single home button to reveal the frame, with perhaps a double click of it switching to the Sugar favourites ring view.

Where did you add that dns pointing at the gateway? Tell us more about the local site setup. DNS at the gateway is common in a DHCP world especially behind a NAT router. It should be possible to see what name servers the NAT router or Gateway is connected to by connecting to the configuration tool and then test them with dig or host. Another tool traceroute can let you see if you have connectivity to the name server. A static address must not be in the DHCP servers pool of addresses. What should I be looking for? - Is bind running correctly on the XS? To understand this... - are there any interesting msgs in /var/log/messages.log from named ? Do the following commands work... (executed on the XS) dig google.com @localhost dig `hostname -f` @localhost - Is /etc/resolv.conf correctly pointing to the named running on the XS? Two interesting google hosts are public name servers: $ host 8.8.8.8 8.8.8.8.in-addr.arpa domain name pointer google-public-dns-a.google.com. $ host 8.8.4.4 4.4.8.8.in-addr.arpa domain name pointer google-public-dns-b.google.com. These name servers can be used on a command line: $ host www.google.com 8.8.8.8 Using domain server: Name: 8.8.8.8 Address: 8.8.8.8#53 Aliases: www.google.com is an alias for www.l.google.com. www.l.google.com has address 74.125.19.104 www.l.google.com has address 74.125.19.103 www.l.google.com has address 74.125.19.147 www.l.google.com has address 74.125.19.99 N.B. that localhost is not resolved by google. This can be important and is commonly solved by /etc/hosts and placing a host reference in host.config. So, do check /etc/host.config you can have the local file /etc/hosts inspected by the resolver code first by setting placing hosts as the first tool in the resolver line and follow that with DNS ( bind ) $ cat /etc/host.conf multi on order hosts,bind This lets your localhost line in /etc/hosts be seen. It also lets you name hosts on the inside of a NAT that uses private networks. 192.168.0.0 – 192.168.255.255 172.16.0.0 – 172.31.255.255 10.0.0.0 – 10.255.255.255 and watch for the zero configuration IP address space 169.254.0.0/16 as described in RFC 3927 http://en.wikipedia.org/wiki/Private_network Private networks are interesting. They cannot be auto routed and there is no global reverse lookup Name servers for private networks are interesting. They are a couple cases, the ``easy'' one is where all the network is routed and no private networks are involved. Private networks are more interesting because outside of the private network a ``smart'' router's address is returned while inside local private network numbers are returned. Debugging requires knowing if private net numbers are being used and if the name server is returns two views one for outside lookup and another of inside lookups. Netmasks?? this is another topic of interest. Netmasks establish broadcast conventions that are important for many services. One tactic is to take advantage of local /etc/host resolution and fill in many of the interesting lookups by hand while debugging a name server. Once the debugging is finished comment out or delete the hand made edits to avoid future confusion (important). An XS server can sit inside or on the edge of a local network so the local decisions for setting up a network environment can be important. hth, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect -- T o m M i t c h e l l mitch-at-niftyegg-dot-com ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
