Since my last message I went back to kernel 2.6.13 and went through the linuxwacom manual installation instructions. That lead me to do exactly those
things you suggested - and it works! I've just been playing with the tablet in the gimp.

I'll now try the same with kernel 2.6.15 and report back. That will be next week.

Thanks again for your help.

Wacom Volito2 on Gentoo Linux HOWTO


First, a big thank you for the instructions. I was able to install my USB Wacom Graphire4 in ~27 minutes.

System: AMD64 {~amd64}
Kernel: Vanilla Sources 2.6.15.1

A few points of clarification which might be helpful to others:


Quote:
7) create the file /etc/udev/rules.d/10-wacom.rules and write the following line in it:
Code:
KERNEL="event*", SYSFS{idVendor}="056a", NAME="input/%k", SYMLINK="input/wacom%e"


In the latest versions of udev rules, there is a default local rules file /etc/udev/rules.d/10-local.rules. Just add the above line to this file instead of creating a new one.


Quote:
10) edit /etc/X11/xorg.conf

This section should already exist; you must add the lines regarding "stylus".
Code:
Section "ServerLayout"
   Identifier     "Default Layout"
   Screen         0  "Screen0" 0 0
   InputDevice    "Mouse0" "CorePointer"
   InputDevice    "Keyboard0" "CoreKeyboard"
   InputDevice    "stylus" "SendCoreEvents"
EndSection


The default screen in the "ServerLayout" section for many people will appear as:
Code:
   Screen      "Screen1"

Just add the line:
Code:
   InputDevice    "stylus" "SendCoreEvents"

to the ServerLayout section. No need to replicate the above.


Quote:
TROUBLESHOOTING

PROBLEM: There's no /dev/input/wacom.
SOLUTION: If you just added the udev rule, try rebooting your system. If that fails, try running:
# ls /dev/input/
# wacdump /dev/input/eventX
with all the listed devices and see if the tablet is there.

This could be carlified by adding the following:

Quote:
Where X is a number. There are usually several /dev/input/eventX files. You are trying to find the event file which applies to your tablet. If such a file does exist, then you most likely have a typo in the udev rules line you added earlier. Double check your udev rule for an error.

WORKAROUND: If udev still isn't setting /dev/input/wacom for you and you've identified the /dev/input/eventX file assigned to your tablet, replace in the "InputDevice" section the line:
Code:
   Option        "Device"        "/dev/input/wacom"
with:
Code:
   Option        "Device"        "/dev/input/eventX"

You're quite welcome. I'm glad you improved the suggestions to make them more generic.

And a big thanks to you for writing the instructions to begin with. It made my life so much easier.

:D

Try replacing hidcore.c and wacom.c in your kernel with those provided by the latest linuxwacom drivers and recompile it.


Well, being lazy I thought I'd try the easy route first - and it worked.

Here is what I did step by step.

ln -snf linux-2.6.15-gentoo-r1/ linux
boot linux-2.6.15-gentoo-r1 (with tablet not connected)
emerge linuxwacom
Note that the /dev/input/event* do not exist
Reboot with tablet connected (still no /dev/input/event*)
Put 10-wacom.rules back in /etc/udev/rules.d
Reboot (still no /dev/input/event*)
startx - now the /dev/input/event* exist, along with /dev/input/wacom -> /dev/input/event2
tablet works in gimp

I don't know which part of this series of steps did the trick, but perhaps you do.

Thanks very much for your help and for making the ebuild available - it is good to know there is a
painless way to keep my system updated yet retain use of my drawing tablet.

Seems like you compiled the kernel parts as modules and you forgot to call modprobe.

when I do wacdump /dev/input/event2 I can see that tablet is working

but when I do wacomcpl
Code:

We didn't find any Wacom device.
 Please make sure the device's

 is embeded into its identifier string


Gimp can't use tablet too. I don't know where I did mistake.

did you compile x.org and linuxwacom after setting the sdk flag?

go look in /var/log/Xorg.0.log for an error message

Hello!

I just emerged linux-2.6.15-gentoo-r1 and linuxwacom 0.7.2, when I compile linuxwacom I got following error:
Code:
make[4]: Entering directory `/usr/src/linux-2.6.15-gentoo-r1'

File /usr/src/linux-2.6.15-gentoo-r1/Module.symvers is really missing. It is included in older kernels however .....
Shall I copy the file from older kernel source ? (is it safe ??)

either you issued a make mrproper, thus deleting the configuration file, or you are using a kernel source that you never configured in the first place. In either case, you have to import and old .config and then call make oldconfig or re-configure the kernel from scratch.
Tip 1: when you emerge gentoo-sources, the previous ones are not overwritten nor deleted, and the old .config file is not automatically imported.
Tip 2: in case you lost it, you can fetch your current config file from /proc/config.gz:
gzip -cd /proc/config.gz > /usr/src/linux/.config

Thanks for advice. You're right I tried to install wacom drivers straight to new kernel sources .... I compiled the new kernel, installed wacom drivers and recompiled again. This is fine, however every time I boot with new kernel my machine freezes at login prompt .... this is however kernel problem :( and it is not related to wacom .... once I'll manage to run new kernel I'll continue with this how-to!

Thanks

I solved few problems I had with my new kernel ... now I booot all the way to the login promt but can not type anything ...
Did I forget to compile something ? My old kernel works fine however I'd like to configure my new kernel from scratch (I'm using UTF, but not sure if it is related)

I enabled CONFIG_INPUT_EVDEV as suggested in this how-to, could this be somehow connected with the typing problem ???

Jan
p.s. as this is probably not related to wacom I posted new post http://forums.gentoo.org/viewtopic-t-439192-highlight-.html.

Hello!

I spend whole day trying to solve the typing problem with 2.6.15-r1 kernel .... unfortunately without any success.
After, I tried with my old working kernel 2.6.12-r6 .... and everything works!!!

I'm still very curious what's wrong with my 2.6.15-r1 kernel ....

Anyhow, the reason why I need tablet is that I'd like to measure trajectory and pressure while writting (mostly kanji) characters and save it to file for later processing. Is there a smart way how to read output of tablet ???
I found a option in kernel called "Input debugging" (CONFIG_INPUT_EVBUG). I'm gonna give it a try .... I'm wondering if I'll be able also to measure pressure.

Thanks
Jan

p.s. one detail regarding how-to:
In kernel part
"Device Drivers -> Wacom Intuos/Graphire tablet support" should be "Device Drivers -> USB support -> Wacom Intuos/Graphire tablet support"

Thank you very much for the guide! I just installed Graphire4 but it's working as a mouse (i.e relative not absolute), will get back when I get working :)

It's a kernel problem.
First of all, I'd recommend you to set RC_DEVICE_TARBALL="no" in /etc/conf.d/rc, and reboot. This way you'll remove all the unneeded devices.
You have to make sure that (1) you're using at least a 2.6.15 kernel and (2) all the devices I listed are compiled and loaded.

Then do a
Code:
dmesg | grep wacom


Also, disconnect your table, reconnect it, and do a
Code:
dmesg | tail

Emulagame: Why don't you also use the udev rule for the /dev/input/wacom device?

Hello!

Anyhow, the reason why I need tablet is that I'd like to measure trajectory and pressure while writting (mostly kanji) characters and save it to file for later processing. Is there a smart way how to read output of tablet ???

Don't know about tilt, but for pressure you could try analysing the bitmaps created with gimp.

if the kernel doesn't recognize it as /dev/input/eventX, it won't appear as /dev/input/wacom regardless of the rule.

Wacom Graphire 4 :
After trying to get the Wacom tablet to behave nicely for a couple of weeks now, I have only suceeded in getting it to act as a mouse (relative positioning, not recognised by gimp).

Code:

Section "InputDevice"
   Identifier "USB Mouse"
   Driver "mouse"
   Option "Device" "/dev/input/mice"
   Option "ZAxisMapping" "4 5"
   Option "Buttons" "5"
EndSection

#Section "InputDevice"
#   Driver "wacom"
#   Identifier "cursor"
#   Option "Device" "/dev/input/wacom"
#   Option "Type" "cursor"
#   Option "USB" "on"
#   Option "Mode" "Absolute"
#   Option "Vendor" "WACOM"
#EndSection

Section "InputDevice"
    Driver "wacom"
    Identifier "stylus"
    Option "Device" "/dev/input/wacom"
    Option "Type" "stylus"
    Option "USB" "on"
    Option "Mode" "Absolute"
    Option "Vendor" "WACOM"
EndSection

#Section "InputDevice"
#    Driver "wacom"
#    Identifier "eraser"
#    Option "Device" "/dev/input/wacom"
#    Option "Type" "eraser"
#    Option "USB" "on"
#    Option "Vendor" "WACOM"
#EndSection

...

Section "ServerLayout"
   Identifier   "Layout"
   Screen      "Screen 0" 0 0
   InputDevice   "USB Mouse" "CorePointer"
   InputDevice   "Keyboard1" "CoreKeyboard"
   #InputDevice "Keyboard1" "Touchpad"

   #InputDevice "cursor" "SendCoreEvents"
   InputDevice "stylus" "SendCoreEvents"
   #InputDevice "eraser" "SendCoreEvents"

   Option "BlankTime" "5"
   Option "StandbyTime" "10"
   Option "SuspendTime" "20"
   Option "Offline" "30"
EndSection

...


package.use has the required sdk flags for x11-base/xorg-x11 and x11-misc/linuxwacom (which I have recompiled 5 further times just to be sure I didn't miss anything). My kernel has evdev, wacom and usbhid compiled in, although I have tried leaving evdev and wacom as modules due to the messages below.

Code:

As far as I see I can't see much going wrong...
With the wacom and evdev as modules I get

Everything is all fine in wacdump /dev/input/wacom
The ioctl messages are making me suspicious anyhow because I have a screensize of 1280x800, so it could just be me and not Graphire4 in general.

On a side note, the above is exactly the same before and after I manually load the wacom and evdev modules, so I think X11 automatically does it and adding to modules to be loaded at startup is an unnecessary step.

Reading through the detailed linuxwacom guide it says I should see Driver=wacom
Code:

T:  Bus=04 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=1.5 MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=056a ProdID=0015 Rev= 4.03
S:  Manufacturer=WACOM
S:  Product=CTE-440-U V4.0-3
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr= 40mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=01 Prot=02 Driver=usbhid
E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=10ms


Is that a problem?
Code:

amir genjix # dmesg | tail

Try replacing wacom.c and evdev.c with those provided in the latest linuxwacom sources.

Also, try to temporarily disable /dev/input/mice from your xorg.conf.

Following the guide through a bit I saw this:
Quote:
linuxwacom detailed guide:
Out of Range Values

At present, we are discovering a number of problems with out-of-range values. Rest assured, we are looking into it, so if you encounter them yourself, you might consider check the mailing list for similar problems, and if your problem is unique, let us know. When the driver is behaving better, I'll increase the priority of this class of problem. Until then, you'll probably just get a message back saying "sorry, and yes, we know." The most serious problem seems to be with runaway pressure settings, so those will get investigated first.


Just to be sure I added
Code:

    Option "TopX" "0"
    Option "TopY" "0"
    Option "BottomX" "30480"
    Option "BottomY" "30480"

But still no luck. I think I might be experiencing this problem :/
Code:

# xsetpointer -l
"Keyboard1"   [XKeyboard]
"USB Mouse"   [XPointer]
"NVIDIA Event Handler"   [XExtensionDevice]
"NVIDIA Kernel Input Handler"   [XExtensionDevice]
"stylus"   [XExtensionDevice]

# xidump -l
Keyboard1                      keyboard
USB Mouse                      disabled
NVIDIA Event Handler           extension
NVIDIA Kernel Input Handler    extension
stylus                         extension

# xidump -l -v stylus
stylus                         extension
    key: min=8, max=39, num=32
    btn: num=16
    val: axes=8 mode=abs buf=0
    axis[0]: res=0, max=0, max=0
    axis[1]: res=0, max=0, max=0
    axis[2]: res=0, max=0, max=0
    axis[3]: res=0, max=0, max=0
    axis[4]: res=0, max=0, max=0
    axis[5]: res=0, max=0, max=0
    axis[6]: res=0, max=0, max=0
    axis[7]: res=0, max=0, max=0

# xidump -u raw stylus
X Error: 165 BadDevice, invalid or uninitialized input device
Unable to open input device 'stylus'

# xidump stylus
X Error: 165 BadDevice, invalid or uninitialized input device
Unable to open input device 'stylus'


Might be worth noting in your guide with a disclaimer :?

WOW! Works! Thanks :)

Just going to re-enable mice and get rid of top/bottom settings :)
