I'm working on getting FreeBSD Stable (svn rev 235652, AMD64) running to my satisfaction on a Toshiba M750. The challenge is that it contains a builtin Wacom touchscreen. People report it working under Linux using the linuxwacom driver also present in ports. Unfortunately I fail to get it working under FreeBSD and find no reports on the web of anyone that succeeded for FreeBSD. I have the impression that it is related to the kernel not detecting it properly, which is why I ask the question on the Stable mailing list. My apologies if it should have gone elsewhere. Below a short summary of what I did in trying to get this to work. I've installed the x11-drivers/input-wacom port and enabled it by using wacom_enable in /etc/rc.conf. Upon a reboot I get the message that /boot/modules/uwacom.ko can not be loaded in dmesg. This is correct as this file doesn't exist, but it highlights the problem as this driver is only needed for Wacom tablets connected through USB. Yet this is a builtin tablet which is connected by a serial connection. There is no other mention of anything wacom related in dmesg -a. Enabling webcamd which is often mentioned for USB connect tablets as being important makes no difference. Moreover building x11-drivers/input-wacom with the USB flag set also doesn't build the driver. I then explored further using devinfo -v, which indeed shows the presence of the tablet giving the following message: unknown pnpinfo _HID=WACF009 _UID=0 at handle=\_SB_.PCI0.FNC0.TBLT This according to the inputwacom wiki is indeed the device I'm trying to get working, see http://sourceforge.net/apps/mediawiki/linuxwacom/index.php?title=Device_IDs but it doesn't appear in dmesg at all. If I grep through the FreeBSD source I only find a mention of the older Wacom Tablet generation (WACF004 in this case) in the serial driver files, i.e. /sys/dev/uart/uart_acpi.c Unfortunately that is the point at which I am completely stuck as I don't directly see how I can ensure that the Wacom Tablet is picked up correctly, so any suggestion how to proceed would be highly appreciated. Note that it might simply be that I don't understand how I should enable the appropriate serial connection?. _______________________________________________ freebsd-stable <at> freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscribe <at> freebsd.org"
