Hey there,
I'm trying to get my eGalax touchscreen to work but it been kinda hard to find recent information about it. All that I learned is that people were using xf86-input-evtouch and/or xf86-input-egalax many years ago, but these packages do not exist anymore. I saw people using evdev driver, but it also doesn't work for me, and I'm interested in multitouch capability, which is not possible with evdev anyway.

The piece in Xorg.0.log:
Code:

At some point I managed to get it working with evdev, by unplugging my usb mouse and plugging it later or something like that. However, as I explained, I'd prefer to have multitouch working as well, so evdev would be a last resource.

Thanks in advance!

Yes, I tried the first one. Its not automatically used by X, and if I put in xorg.conf it says that the module does not exist (it exists and I can load and see it).
The second one seems to not be ANYWHERE; its simply not there as it has as a prerequisite this "OF" thing which I couldn't find as well.

OF apparently is selected by other choices as opposed to being enabled by the user.
apparently irrelevant though as x32 not x64 required for these modules



https://wiki.archlinux.org/index.php/Touchscreen or http://forums.gentoo.org/viewtopic-t-890234-start-0.html may be more helpful than i am.
