Hi,
I am trying to get the tablet screen working on the X41. After googling I found that it once worked with OpenBSD 4.4 and linuxwacom-0.8.2: http://webcache.googleusercontent.com/search?q=cache:2ywAxrd95GIJ:https://osuny.co.uk/~azure/txt/openbsd_thinkpad_x41_tablet.txt However, a lot has changed since then. 0.8.2 doesn't work anymore with the -current OpenBSD X11 version and I also don't get any newer version of linxuwacom to compile for other reasons (seems to have something todo with LINUX_INPUT). Anyone got more luck and/or porting experience? ;-) Michael |

Pen functions fully worked under 4.4-RELEASE. I played around with this a bit tonight (running the 05/29/10 snapshot of 4.7-CURRENT) and after some patching I got linuxwacom-0.8.2 to compile and install (see patch below). The next problem was calibrating the pen. After I setup xorg.conf and restarted, things were way out of whack. Moving the pen to the upper-left corner brought the cursor almost in line with the pen point. Moving the pen away from the upper-left corner of the screen resulted in an increasing distance between the cursor and the pen point. I wasn't sure where to proceed from there. It is possible my patch messes up something important for pen calibration. The InitValuatorClassDeviceStruct function was being called with too many arguments (I removed only what I believed to be bounds checking, but that seemed to satisfy the compiler). Removing OutOfProximity is a change from versions of linuxwacom that came after 0.8.2 and shouldn't hurt anything (especially since we specify Absolute in xorg.conf anyway). None of the calibration tools I've found so far seem to work with OpenBSD. The bundled utility wacomcpl will launch, but doesn't recognize any devices. I found another perl script someone wrote to make calibration easier, but it requires Glib2 and GTK+ perl modules, which are marked as broken in ports. I'll post here if I make any more progress. -sl --- begin patch --- --- src/xdrv/xf86Wacom.c.old Sun May 30 22:46:45 2010 +++ src/xdrv/xf86Wacom.c Sun May 30 22:48:57 2010 @@ -582,14 +582,11 @@ if (InitValuatorClassDeviceStruct(local->dev, nbaxes, #if WCM_XINPUTABI_MAJOR == 0 xf86GetMotionEvents, - local->history_size, #else GetMotionHistory, - GetMotionHistorySize(), #endif ((priv->flags & ABSOLUTE_FLAG) ? - Absolute : Relative) | - OutOfProximity ) == FALSE) + Absolute : Relative)) == FALSE) { ErrorF("unable to allocate Valuator class device\n"); return FALSE; @@ -925,18 +922,6 @@ } pos += cnt; - if (common->wcmDevCls != &gWacomUSBDevice) - { - common->wcmPktLength = 9; - data = common->buffer + pos; - if ( data[0] & 0x18 ) - { - if (common->wcmMaxCapacity) - common->wcmPktLength = 7; - else - common->wcmPktLength = 5; - } - } } if (pos) --- end patch --- |

I have a X41 Tablet here as well and tried to apply your patch - I also had to modify some of the header files to include xorgVersion.h and xorg-server.h instead of the XF86 stuff. It compiled fine but after modifying the kernel (nasty stuff in the howto) and starting X, the machine crashed immediately after the pen hits the display for the first time. I would be happy to help out and test code - but my C knowledge is reduced to the easy modifications mentioned above... -- Oliver PETER email: [hidden email] ICQ# 113969174 "I'm just a simple man trying to make my way in the universe." -- Jango Fett |
