Bug 169118

Does this happen when you startx after the tablet has been plugedin

Yes--it happens every time, whenever used.

The tablet seems not to have the same idea of how big the screen is, and also
seems unsure of where the point 0.0 would be. Sometimes the mouse would be
pretty much in the middle of the screen, with the pen in one of the corners of
the tablet.

What is the version of the wacom kernel module and the xwindows driver.

can you supply the logs, /var/log/messages and the Xorg.0.log
Just the bits from when the wacom drivers load.

Let me know whether this answers your questions.

Alex, please append your X configuration on this bugzilla, the Xorg.0.log excerpt
doesn't shows anything related to wacom driver.

The InputDevice section of /etc/X11/xorg.conf -- no mention of tablet there,
only mouse. However here it is. If this is not the file you need, let me know.

Section "InputDevice"
# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
#       Option  "Xleds"         "1 2 3"

# To disable the XKEYBOARD extension, uncomment XkbDisable.
#       Option  "XkbDisable"

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#       Option  "XkbModel"      "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#       Option  "XkbModel"      "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#       Option  "XkbLayout"     "de"
# or:
#       Option  "XkbLayout"     "de"
#       Option  "XkbVariant"    "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#       Option  "XkbOptions"    "ctrl:swapcaps"
# Or if you just want both to be control, use:
#       Option  "XkbOptions"    "ctrl:nocaps"

Hi Alex,
If you don't use X wacom driver, the tablet will be used along with other mice
(via /dev/input/mice). Please install linuxwacom package and update your xorg.conf
to use the X wacom driver and tell me the results.

Thanks

Aristeu,
I do have the driver installed--had it since I got the tablet.
Which file will indicate whether the driver is being used?
a


up2date linuxwacom

The following packages you requested are already updated:
linuxwacom

if you don't have the wacom section on xorg.conf, the driver won't be used.
I'll attach a simple configuration section.

Created attachment 152947 [details]
relevant parts of xorg.conf

Please notice it's not a complete xorg.conf but only the relevant sections to
be used as example.

Did insert all sections into my xorg.conf and did not see any noticeable
improvement. I am still able to replicate a situation where my stylus arrives at
the end of the tablet's input area before reaching the edge of the screen.

Alex, does the file /dev/input/uinput-devices/uinput-wacom-graphire4-4x5-tablet
exists in your machine? try using the /dev/input/by-id/<your tablet> file
instead.

Alex, any updates?

I am not sure I can follow your instructions correctly. When I run ls on
/dev/input, that's what I get:

$ ls /dev/input/
event0  event2  event4  event6  mice    mouse1
event1  event3  event5  event7  mouse0  mouse2

The problem persists, BTW :)

Hi Alex,
please attach here:

- linuxwacom package version (rpm -qi linuxwacom)
- wdaemon package version (rpm -qi wdaemon)

Alex,
please try using:
http://people.redhat.com/arozansk/wacom_rhel5/kernel-2.6.18-49.el5.wacomtest2.i686.rpm
and
http://people.redhat.com/arozansk/wacom_rhel5/linuxwacom-0.7.8.3-1.el5.i386.rpm

Alex, any news?

Since I am using a Red Hat Helpdesk supported system, I had to ask them if that
would mean they won't support my box anymore. It meant exactly that.

So my compromise with them was to install the alternative kernel, test the fix
and then remove it.

Unfortunately, right now the time is bad for me to muck around with my system,
as I have a few deadlines coming up. I will have more time after Feb 18th, and
will report the results to you then.

Cheers,
Alex

the kernel issue is ok, you can do:
    rpm -ivh --force /home/amaier/Desktop/kernel-2.6.18-49.el5.wacomtest2.i686.rpm

for the linuxwacom package, use rpm -Uvh when upgrading a package:
    rpm -Uvh /home/amaier/Desktop/linuxwacom-0.7.8.3-1.el5.i386.rpm

the kernel doesn't needs it because it's possible (and it can make sense) to have
more than one version of kernel.

Packages installed successfully, I will report on the behaviour in a few days
after I have had a chance to observe. Thanks for your help so far!

So after a few days I can tell that the behaviour has been somewhat better, but
under load the coordinates still slip.

Also (and I am not sure whether it is related, but since the only change I had
made was the installation of two packages) I can no longer use RealPlayer--it
says that the resourse is used by another process. This happens even when all
processes that could potentially block the resource (like firefox) are closed...

I don't think RealPlayer should affect the tablet behaviour, but thanks for
reporting.

What kind of load is it? Any easy way to reproduce the problem?

It's more like the other way around, RealPlayer fails to access the audio out
device because it is blocked by another process...

As an example of "load" that would impact the tablet behaviour, Thunderbird
Lightning synching with Zimbra once every 15 minutes will surge the CPU load to
85% or more, and at this point the tablet will slip coordinates.

Alex, just as an update: I'm currently working on the RHEL-4 bugs and I'll be
able to come back to this soon.

Alex,
there're test RPMs available on
   http://people.redhat.com/arozansk/wacom_rhel5/
there're no changes on those packages that would solve your load problem, but
if you want to try them while I work on your issue I'll appreciate.

Interested in another data point? I have this issue (without system load) using
Fedora 9 Live USB, all updates installed (except kernel which would render it
unbootable), Graphire 3 USB tablet (I also have a Graphire 2 USB which I haven't
tried)

Alex, any updates?

Paul, I've seen this happen on a tablet with a broken pen (i.e. completely random
gaps without anything visible on the system). If you have the chance, try using
this tablet with another pen of the same model.

sorry, i did not have a chance to test the packages yet. is this the freshest one? "linuxwacom-devel-0.7.8.3-3.el5.x86_64.rpm"

I am running Red Hat CSB kernel version 2.6.18-53.1.14.el5 on an i686 machine.

In the meantime, i keep experiencing the problem where the tablet ends before the screen does :)

Alex,
http://people.redhat.com/arozansk/wacom_rhel5/linuxwacom-0.7.8.3-3.el5.i386.rpm
is the one you're probably looking for. -devel only contains development related
files.
Give it a try and let me know the results

(In reply to comment #31)
Aristeu, there's no chance my pen is broken. I use it all the time and it works beautifully. For me this (the original complaint) has been a very long-standing issue (years old) with multiple (but not all) linux environments and two different models of tablet/pen.

Paul,
notice that by "broken" doesn't imply it simply not working. I had experience
with a Intuos3 4x6 with one of those pens. Without apparent reason, no events
were generated. Not even interrupts. It was like the tablet were dead for some
seconds then resumed working without any reason. After debugging in different
machines and even using it on the Mac OS, the result was the same. The tablet
were replaced by a new one, the problem never happened again.

So, that's why I suspected that it could be something like that.

Paul, please feel free to reopen this on RHEL6 if the problem still exists.
