I have a web-based application running on a relatively low spec Ubuntu box (it was originally set up as a server install, but Gnome (I think [*]) was added with Firefox).
They want to do away with keyboard and mouse so that means a touch screen. Any experience/suggestions/recommendations?
Most of the interface is click only (a few elements are hover but they're not critical). There is the need to login so that'll need a pop-up keyboard of some kind, although we'd also like to look at barcode scanning support (all staff have a swipe card with barcode on it and that could bypass the keyboard-based login).
I wouldn't rule out a standalone all-in-one desktop PC with touch screen acting as a client to the existing box (which goes back to being headless). Cost may be prohibitive though.
[*] How do I check via SSH what desktop manager was installed?

If you need an On Screen Keyboard then perhaps the Yocto project is a good start. I think they have a very customisable pop up keyboard.
*Most* touchscreen hardware is just a USB HID profile device and should more or less just work. Some hardware I have seen does long press to right click (not that it sounds like you need right click), if not I think that is achievable in software.

'whereis gdm' and if it exists do 'cat /etc/gdm3/greeter.gsettings' and see what the default DM is set to perhaps. If GDM doesn't exist follow the same process for KDM or check the package manager.

Thanks, I'll take a look.

OK, gdm is there, /etc/gdm3 isn't but /etc/gdm is; no greeter.settings but custom.conf has "DefaultSession=gnome-2d".
However, I'm thinking it probably won't matter too much if to all intents and purposes I'm just going to see a USB mouse.
Thanks for the pointers.

I've been doing some research into this, without the luxury of having a touch screen to play with. There seem to be lots of people having issues (pick a touch screen model, google for it +linux, find people having issues on Ubuntu Forums etc with varying degrees of success compiling drivers etc).
I need to quote a customer to add a touch screen to an existing Ubuntu 11.04 system (upgrading the OS version isn't necessarily a problem but just increases the work needed - especially given that 11.04/11.10 are no longer supported). So it would really help to have some clues as to which manufacturer's screens will give me the least grief - any suggestions?
(Aside: I expect that upgrading to 12.04 via 11.10 and then keeping it on a supported LTS version will be happening at some point.)
