Hi forum,

The recent change of Xorg from HAL to udev seems to cause me plenty of problems. The latest is with Wacom pen touchscreen on Fujitsu T5010. The touchscreen worked fine beforehands with HAL but with Xorg 1.9 and udev it has gone completely unresponsive. I believe I have related ebuilds correctly installed but still the device is somehow lost, because when trying to debug it I get this while moving the pen on the screen:


# isdv4-serial-debugger -v /dev/ttyS0
... Opening device '/dev/ttyS0'.
... Baud rate is 38400

dmesg has only this for the device:

# dmesg | grep ttyS
[    1.560570] 00:05: ttyS0 at I/O 0x220 (irq = 4) is a 16550A

I have all Wacom and Fujitsu touchscreen related things compiled in the kernel. Here are the USE flags for the related ebuilds:

[ebuild   R   ] x11-base/xorg-drivers-1.9  INPUT_DEVICES="evdev synaptics wacom -acecad -aiptek -elographics -fpit -joystick -keyboard -mouse -penmount -tslib -virtualbox -vmmouse -void" VIDEO_CARDS="intel -apm -ark -ast -chips -cirrus -dummy -epson -fbdev -fglrx (-geode) -glint -i128 (-i740) (-impact) -mach64 -mga -neomagic (-newport) -nouveau -nv -nvidia -r128 -radeon -rendition -s3 -s3virge -savage -siliconmotion -sis -sisusb (-sunbw2) (-suncg14) (-suncg3) (-suncg6) (-sunffb) (-sunleo) (-suntcx) -tdfx -tga -trident -tseng -v4l -vesa -via -virtualbox -vmware (-voodoo) (-xgi)" 0 kB

And finally my emerge --info if it helps here:

What do you see in the logs about this device ?
Did you reemerge the driver after server upgrade ?
Do you have an entry that assigns the driver to the device ?

Yes, I reemerged the driver.

I can't give you printouts now because I'm away from the affected computer, but Xorg doesn't recognize the digitizer even if there are promisingly looking default rules in /usr/share/X11/xorg.conf.d/50-wacom.conf. I also tried to copy my old xorg.conf input sections to /etc/X11/xorg.conf.d/50-wacom.conf but no luck there.

xinput does not show devices that would be related to the digitizer according to the /usr/share/X11/xorg.conf.d/50-wacom.conf. This makes me doubt that introducing these devices doesn't get done correctly by udev.

Has there been any news or revelation here? I'm having identically the same problem. Same laptop, same situation (migration from HAL to udev), same output from dmesg and the serial debugger, same USE flags for xorg-drivers and xf86-input-wacom, and also have promising entries in 50-wacom.conf. I also had a working tablet under HAL and would like to reclaim that functionality.

I still very much consider myself a Gentoo neophyte but can post whatever reports you might deem necessary to help resolve this.

Thanks in advance!

Hello after a while...

Eventually, I got my touchscreen working by checking my Xorg configuration according to Linux Wacom wiki:

I can't define whether I was lacking something or whether the upgrade of the xf86-input-wacom helped. However, when I newly made up a xorg.conf for the touchscreen, the touchscreen devices began to run as smoothly as before the forementioned Xorg upgrade.
