Clients like xdpyinfo use XF86VidModeGetModeLine() to get the video timings, which include the current screen resolution. I'm used to using this to see whether the resolution has been changed with and . That sort of resolution change leaves you with a virtual desktop, so I don't know if it makes sense with a touch screen, but if so XF86VidModeGetModeLine *doesn't* report the viewing window, which makes the returned values less helpful. XF86VidModeGetModeLine is specific to XFree86 (and derivatives) and, more significantly, is a client call. You would have to trace the code back to find a way to get the equivalent information from within the server. -- Andrew C.

Re: magictouch touch screen driver
I tried using the screenInfo everytime the x,y position is scaled and
returned, but that does not seem to help. I do not know how to support
screen resolition changes. If anybody has an idea, let me know.
The driver is basically a slightly massaged dmc driver, there is probably
still some stuff to clean. Here it is as a shell archive (don't know it
the maillist rejects attachments...)

Re: magictouch touch screen driver
I have my driver for the serial MagicTouch touchscreen working. There is just one thing that I am not sure of: if the resolution is changed dynamically (by some program running fullscreen for example), the scaling is off. How do I find if the resolution has changed ? Right now, I check the screen size when the device inits, and store that away. Should I instead use the actual screen size everytime through screenInfo ? Is that safe ? Also, how can I twiddle the DTR, RTS lines, I do not find some abstraction for that... then, how do I submit the driver ? send it to this list ? bruno On Sun, 22 May 2005 [EMAIL PROTECTED] wrote: > Hi everybody, > > I am interested in getting the magictouch driver running.
