2.6.14-1.1653_FC4 and egalax driver?

[jokers]

Does anyone have the egalax touchscreen driver working with 2.6.14-1.1653?

The egalax driver uses verify_area. This is Obsolete/deprecated in the 2.6.14 kernel and has been replaced with access_ok.
I modified the tkusb.c source code as follows, the touch screen is now working.

in directory touchkit/usb/
sed -e 's/verify_area(/! access_ok(%/' tkusb.c > tkusb.c.new
mv tkusb.c.new tkusb.c
recompile the driver, load the module and restart tpaneld.

At least it works for you... I may have other issues but I can't get it working after the update and still haven't. I already did your code patch before and that helped but my real issue is that everything seems to load up fine, but Xorg.0.log complains about the /dev/tkdat0 entry. It shows an error with OpenSerial...

The touchscreen is unresponsive, so its hard to get a clue where to debug this thing. I think I'll do better just reinstalling fedora fresh.

Thanks for replying and offering me proof that it works for that distro/kernel.

If you can, I would greatly appreciate a full copy of someone's working touchscreen xorg.conf including the modeline's you use... just paste in the whole thing.

What kind of touchscreen do u have? Mine is the Xenarc 700tsv.

Not working... man this sukx. Ok: I tried going the evtouch_drv.o and got close, but I couldn't stop the erratic mouse movements and even though the touchscreen was responding, it wasn't calibrated properly. I followed the calibration steps using ./calibrate.sh and that sort of helped. I tried SwapY=1 but that didn't do it.

SO I gave up on that route and went back to try tkusb.ko again, the eGalax option. First I patch out the verify_area refs with access_ok, then I compile and installs fine. I have in my xorg.conf file this section:

Section "InputDevice"
Identifier "TKPANEL"
Driver "touchkit"

EndSection

In ServerLayout: InputDevice "TKPANEL" "SendCoreEvents"

Section "InputDevice"
Identifier "TKPANEL"
Driver "touchkit"
Option "Device" "/dev/tkdat0"
EndSection

And I restart X and NOTHING HAPPENS! I get no errors, I see the driver loads fine and logs happy messages. Xorg.0.log shows it load fine, dmesg shows a clean setup, tkusb is listed under lsmod, tpaneld is running, YET NO TOUCHSCREEN. This touchscreen has worked in early FC3 but now just can't get it working...

If I try cat /dev/tkpanel0 I get this: Bad address. ??? that means what?

Anyone have any clues? This is touchscreen hell and I have to get out, so please help with Fedora...
