| hweg162 | hi | 12:18 |
|---|---|---|
| hweg162 | is there any successor for grail? i checked http://bitmath.org/code/grail/ and the download links are dead | 12:19 |
| bregma | hweg162, there's https://launchpad.net/grail | 12:23 |
| bregma | it's packaged and available in the last few Ubuntu releases | 12:24 |
| hweg162 | i know it's packaged. i just wondered if there is any development going on. | 12:24 |
| bregma | it's fairly mature at this point | 12:25 |
| hweg162 | okay, i think i need to explain what i am doing :) | 12:26 |
| bregma | I'm not aware of any active development, but I could be mistaken | 12:26 |
| hweg162 | i am testing multitouch capabilities on a samsung slate pc series 7 | 12:26 |
| hweg162 | with both ubuntu 12.04 and 12.10 | 12:26 |
| hweg162 | unity recognizes three finger gesture out of the box, giving the window move and resize handles | 12:27 |
| hweg162 | but four fingers aren't recognized | 12:28 |
| bregma | you might want to verify the touch data coming from X (xinput -test-xi2) to make sure more than 3 touches are recognized | 12:29 |
| hweg162 | 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 |
| bregma | sounds like a driver problem | 12:30 |
| hweg162 | kernel driver or Xorg driver or... | 12:30 |
| bregma | mtview only talks to the kernel | 12:31 |
| hweg162 | oh you are right. it opens /dev/input/event* | 12:31 |
| bregma | there are some newer tool in the evemu-tools package, let you capture data for later replay | 12:32 |
| hweg162 | 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. | 12:32 |
| bregma | you're going to have trouble opening the device reliably while X is running | 12:33 |
| bregma | it works best from a text console | 12:33 |
| hweg162 | but mtview needs X for displaying its window | 12:33 |
| bregma | yeah, pretty nasty, that catch-22 | 12:34 |
| bregma | we haven't really used mtview since the XINPUT changes went in to the X server, grabbing the device | 12:34 |
| bregma | that's what the evemu tools are for | 12:34 |
| bregma | except they dump text data | 12:35 |
| hweg162 | okay. so the wiki pages are simple outdated? | 12:35 |
| bregma | most likely | 12:35 |
| hweg162 | okay. i'm gonna check the xinput -test-xi2 thing first | 12:36 |
| === dandrader is now known as dandrader|afk | ||
| hweg162 | so XI2 are multitouch event in Xorg? | 12:37 |
| hweg162 | bregma: if xinput -test-xi2 reports RawTouchEnd and TouchEnd events, does that mean MT is basically working? | 12:52 |
| === MacSlow is now known as MacSlow|lunch | ||
| hweg162 | 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? | 13:18 |
| bregma | hweg162, that driver was deprecated some time ago | 13:30 |
| hweg162 | that's valuable info, thanks | 13:31 |
| bregma | unfortunately, I don;t know enough about the low-level protocols (evdev, etc) to help out much | 13:31 |
| bregma | the evdev events are documented, and the xinput events are documented, but not in one central place | 13:32 |
| hweg162 | afaik the kernel delivers MT events using a specific protocol (mtdev?) | 13:33 |
| bregma | yes | 13:42 |
| bregma | there are a number of devices out there that do not implement the protocol correctly | 13:43 |

| LIDH | hello | 18:10 |
| LIDH | i need help configuring a PS/2 touchscreen device | 18:11 |
| LIDH | can't get it to be detected | 18:11 |
| bregma | does 'sudo lsinput' list anything that might remotely look like your input device? | 18:21 |
| === dandrader|afk is now known as dandrader | ||
| === dandrader is now known as dandrader|afk | ||
| LIDH | nope | 19:14 |
| LIDH | 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 | 19:15 |
