Hmm, it works for me. Do you have anything in your log files concerning xlock and authentication failures? Below is the output in `journalctl -f _UID=1000` when I type my password twice to unlock: 8月 02 23:20:40 helium xlock[8853]: Start: alick, alick, :1 8月 02 23:20:53 helium xlock[8853]: Stop: alick, alick, :1, 0m 13s Below is the output when I type the password once, then press enter multiple times and the login attempt fails, then type the password twice to login: 8月 02 23:21:24 helium xlock[8876]: Start: alick, alick, :1 8月 02 23:21:39 helium xlock[8876]: pam_unix(xlock:auth): authentication failure; logname=alick uid=1000 euid=1000 tty=:1 ruser= rhost= user=alick 8月 02 23:21:41 helium /etc/gdm/Xsession[4991]: (polkit-gnome-authentication-agent-1:5171): polkit-gnome-1-WARNING **: No icon for themed icon with name 'fprint' 8月 02 23:21:43 helium /etc/gdm/Xsession[4991]: [fvwm][ComplexFunction]: <<ERROR>> Grab failed in function EWMHActivateWindowFunc, unable to execute immediate action 8月 02 23:21:44 helium /etc/gdm/Xsession[4991]: [fvwm][ComplexFunction]: <<ERROR>> Grab failed in function FuncFocusWindow, unable to execute immediate action 8月 02 23:22:06 helium unix_chkpwd[8907]: check pass; user unknown 8月 02 23:22:42 helium unix_chkpwd[8916]: check pass; user unknown 8月 02 23:22:42 helium xlock[8876]: pam_unix(xlock:auth): authentication failure; logname=alick uid=1000 euid=1000 tty=:1 ruser= rhost= user=root 8月 02 23:22:42 helium xlock[8876]: pam_succeed_if(xlock:auth): requirement "uid >= 1000" not met by user "root" 8月 02 23:22:43 helium xlock[8876]: xlock: failed unlock attempt on user alick 8月 02 23:23:26 helium xlock[8876]: Stop: alick, alick, :1, 2m 2s Here 8月 means August in English FYI. Seems like the second time asking for password is to feed it to polkit authentication? 'fprint' is short for finger print, and I do have finger print authentication device on my Lenovo Thinkpad T400. However it is disabled in gnome-control-center. Created attachment 796437 [details]
screenshot of xlock debug mode
I did some more investigation today. When I execute xlock -debug -mode blank, I will get results in the screenshot attached above. Note that in the middle of the black xlock window, there is the second password prompt (密码 in Chinsese). And there is a popup window which asks for authorization by FPrint. I think this might be a problem with polkit on computers with fingerprint device. Is it so?
There is one more wired thing. My default locale is Chineses (zh_CN.UTF-8), and when I execute
LANG=C xlock -debug -mode blank
the popup window will never show up. Currently I am using this method to walkaround the issue...
Problem persists in Fedora 20. Even worse: if xlock is started from another display in a dual-head configuration (e.g. DISPLAY=:0.1), then xlock always fails to unlock the screen after 60 seconds of (failed) password validation. P.S.: this is a regression since xlock was working perfectly with Fedora 18 Created attachment 840377 [details]
xlock never unlocks from :0.1
When started from any DISPLAY other than :0.0 using a non-US locale (e.g.: LANG=fr_FR.utf8, LANG=ja_JP.utf8, etc.), xlock does not show the second password prompt and thus never unlocks.
Bug fix was trivial: a compilation flag was missing on Fedora 19 and 20 builds. Patch attached, and a test build is available here: http://koji.fedoraproject.org/koji/taskinfo?taskID=6326814 Source RPM: http://kojipkgs.fedoraproject.org/work/tasks/6815/6326815/xlockmore-5.43-4.fc20.src.rpm Build for armv7hl architecture: http://kojipkgs.fedoraproject.org/work/tasks/6815/6326815/xlockmore-5.43-4.fc20.armv7hl.rpm Build for i686 architecture: http://kojipkgs.fedoraproject.org/work/tasks/6817/6326817/xlockmore-5.43-4.fc20.i686.rpm Build for x86_64 architecture: http://kojipkgs.fedoraproject.org/work/tasks/6816/6326816/xlockmore-5.43-4.fc20.x86_64.rpm Created attachment 840511 [details] Proposed fix for bug #991010 xlockmore-5.43-4.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/xlockmore-5.43-4.fc19 Thanks for the patch.
