[12:18] hi [12:19] is there any successor for grail? i checked http://bitmath.org/code/grail/ and the download links are dead [12:23] hweg162, there's https://launchpad.net/grail [12:24] it's packaged and available in the last few Ubuntu releases [12:24] i know it's packaged. i just wondered if there is any development going on. [12:25] it's fairly mature at this point [12:26] okay, i think i need to explain what i am doing :) [12:26] I'm not aware of any active development, but I could be mistaken [12:26] i am testing multitouch capabilities on a samsung slate pc series 7 [12:26] with both ubuntu 12.04 and 12.10 [12:27] unity recognizes three finger gesture out of the box, giving the window move and resize handles [12:28] but four fingers aren't recognized [12:29] you might want to verify the touch data coming from X (xinput -test-xi2) to make sure more than 3 touches are recognized [12:30] so i need a way to debug this. i installed mtview and ran it. in mtview only two fingers are handled correctly. if i touch the display with three fingers it looks like random coordinates are reported from the hardware/driver/lib/whatever [12:30] sounds like a driver problem [12:30] kernel driver or Xorg driver or... [12:31] mtview only talks to the kernel [12:31] oh you are right. it opens /dev/input/event* [12:32] there are some newer tool in the evemu-tools package, let you capture data for later replay [12:32] btw, i don't know under which circumstances mtview manages to grab that device. sometimes it's "cannot grab device" and sometimes it just works. each time run as root in X. [12:33] you're going to have trouble opening the device reliably while X is running [12:33] it works best from a text console [12:33] but mtview needs X for displaying its window [12:34] yeah, pretty nasty, that catch-22 [12:34] we haven't really used mtview since the XINPUT changes went in to the X server, grabbing the device [12:34] that's what the evemu tools are for [12:35] except they dump text data [12:35] okay. so the wiki pages are simple outdated? [12:35] most likely [12:36] okay. i'm gonna check the xinput -test-xi2 thing first === dandrader is now known as dandrader|afk [12:37] so XI2 are multitouch event in Xorg? [12:52] bregma: if xinput -test-xi2 reports RawTouchEnd and TouchEnd events, does that mean MT is basically working? === MacSlow is now known as MacSlow|lunch [13:18] it looks like xf86-input-multitouch (which isn't installed by default on ubuntu) has its own gesture recognition (instead of doing it with a library on evdev basis). is this driver deprecated? [13:30] hweg162, that driver was deprecated some time ago [13:31] that's valuable info, thanks [13:31] unfortunately, I don;t know enough about the low-level protocols (evdev, etc) to help out much [13:32] the evdev events are documented, and the xinput events are documented, but not in one central place [13:33] afaik the kernel delivers MT events using a specific protocol (mtdev?) [13:42] yes [13:43] there are a number of devices out there that do not implement the protocol correctly === dandrader|afk is now known as dandrader === MacSlow|lunch is now known as MacSlow [14:52] bregma: thanks again, bye [14:52] yw === dandrader is now known as dandrader|lunch === dandrader|lunch is now known as dandrader === dandrader is now known as dandrader|afk [18:10] hello [18:11] i need help configuring a PS/2 touchscreen device [18:11] can't get it to be detected [18:21] does 'sudo lsinput' list anything that might remotely look like your input device? === dandrader|afk is now known as dandrader === dandrader is now known as dandrader|afk [19:14] nope [19:15] but i think i found a way to get it installed, problem is now i dont get image, because i created a new xorg.conf === dandrader|afk is now known as dandrader
