gentoo + px1800kbd

[darkicekeel]

hello there.
i followed as instructed, but no results. the module is loaded but no change in behaviour. pushing ctrl button results in different effect on the system, making it almost unusable because of the inhibit to change to ttx or also to use special characters or keyboard common shortcuts ctrl+c and so on...

ps: no initram here!
gentoo amd64

ok, fixed: the solution is to pass usbhid.quirks=0x0c45:0x7603:0x4 in GRUB_CMDLINE_LINUX in /etc/default/grub

[darkicekeel]

before that i also tried other solutions, like putting
echo "0c45:7603" > /sys/bus/usb/drivers/usbhid/unbind
inside an rc.local file (and making it executable) but no results
same story with
/etc/modprobe.d/usbhid.conf
options px1800kbd quirks=0x0c45:0x7603:0x4

and

cat /etc/udev/rules.d/50-perixx1800.rules
#ATTRS{idVendor}=="0c45", ATTRS{idProduct}=="7603", MODE="0666", PROGRAM="/bin/sh -c 'echo -n $id:1.1 >/sys/bus/usb/drivers/usbhid/unbind;echo -n $id:1.1 >/sys/bus/usb/drivers/perixxkbd/bind'"

and

/etc/X11/xorg.conf.d/perixx1800.conf
Section "InputDevice"
Identifier "Keyboard0"
Driver "px1800kbd"
Option "XkbLayout" "it"
EndSection

none of this worked, only the grub_cmdline_linux did the trick

Hi @darkicekeel and thank you for the feedback !

I am happy to see you managed to resolve the problem.
Is there any documentation improvement that would have your setup right the first time?

[lolo101]

Actually what you describe looks like what the install.sh does.
Maybe there is an edge case that should be added to the file, what do you think?

[darkicekeel]

i don't really know, and sorry for the delay. but i would just add this successful experience on gentoo as part of some troubleshooting part inside your docs. i'm not a developer so i don't know how much rude is my solution comparing to some correction directly in your install.sh, but i think it will be anyway useful. I found the solution relying on all i could find and trying. I hope this useful information for all both perixxx 1800 owners and gentoo users will save some time.

@darkicekeel do you have a directory named /etc/default/grub.d/ ?
If that directory is missing it would explain why the install script could not insert the quirk

According to this documentation the config files are directly under /etc/grub.d/

I believe that is the most probable root cause 🙂

Reopen to update the install script

i need to check that specific computer but on other gentoo installation i've got i can see that folder in /etc
further confirmation to follow
