[Bug 256429] Re: following finger scan requires carriage-return
Unsure. It uses the workaround patch previously posted (adding a dummy KEY_A key capability to the uinput device). Without the workaround, the uinput device doesn't even show up in xinput list. For some reason, a keyboard uinput device with only a KEY_ENTER is not sufficient to be registered. So while it's more of a workaround than a fix, it does indeed resolve the issue and has absolutely zero side effects. -- following finger scan requires carriage-return https://bugs.launchpad.net/bugs/256429 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 256429] Re: following finger scan requires carriage-return
Attached is a patch to thinkfinger that should workaround the bug by adding a dummy key (KEY_A) to the uinput device. It's certainly not a proper fix to why xorg is not correctly sending the KEY_ENTER but it's certainly an option for those of you who find hitting enter after you swipe annoying and/or don't have an xorg.conf to add the configuration workaround. ** Attachment added: thinkfinger-uinput-hack.patch http://launchpadlibrarian.net/18515541/thinkfinger-uinput-hack.patch -- following finger scan requires carriage-return https://bugs.launchpad.net/bugs/256429 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 256429] Re: following finger scan requires carriage-return
I've attached two samples that show this behavior outside of thinkfinger. They both create a uinput device and send a KEY_ENTER event. In bad.c, when the device is only set up with a KEY_ENTER key, the KEY_ENTER event is not observed in X. However, in good.c, if another supported key (say KEY_A) is added to the uinput device as well, the sending of the KEY_ENTER event works just fine. Both of the testcases work as expected outside of X in the terminal which leads to me to believe something is getting munged in X's input layer. -- following finger scan requires carriage-return https://bugs.launchpad.net/bugs/256429 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 256429] Re: following finger scan requires carriage-return
I can confirm this on Intrepid as well. It seems to be related to libpam-thinkfinger's use of uinput. libpam- thinkfinger creates a uinput device to send a EV_KEY/KEY_ENTER press and release. This event _should_ emulate the enter key being pressed after a finger swipe so that the user does not have to press it manually. I don't see any errors in the pam debug output about sending the enter event. Either libpam-thinkfinger is misusing uinput somehow or GDM is not processing the key event (maybe it's blocking focus on the password prompt textbox?).

[Bug 256429] Re: following finger scan requires carriage-return
After debugging for far too many hours, I have an apparent hack/fix. Simply setting another KEYBIT along with our KEY_ENTER seems to fix the issue. The other KEYBIT can be any value and it doesn't seem to matter if the other KEYBIT is set before or after KEY_ENTER. If another KEYBIT is not set, it appears that the kernel is not sending the KEY_ENTER event. I don't recommend committing this until we figure out what the root cause is, but if anyone else experiencing the problem could test it and verify that it resolves their issue, that'd be great.h ** Attachment added: thinkfinger-pam-uinput.patch http://launchpadlibrarian.net/16970940/thinkfinger-pam-uinput.patch -- following finger scan requires carriage-return https://bugs.launchpad.net/bugs/256429 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 256429] Re: following finger scan requires carriage-return
FYI, this issue of not receiving a key event when only one is set is reproducible in a standalone test program outside of thinkfinger-pam. So either it's a kernel issue or for some reason uinput wasn't designed to work with only a single KEYBIT set (which seems incorrect since it worked with earlier kernels). -- following finger scan requires carriage-return https://bugs.launchpad.net/bugs/256429 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
