Here's some FC4 weirdness. Maybe someone out there can help... I've got my Thinkpad T40 almost all teaked out using ACPI goodness. For the most part, t's working very nicely (albeit without the stock FC4 kernel). There's one thing that's bugging me though. I have a script that gets run whenever I hit the "turn off screen" key combo (Fn-F3). When I run this script as root or my normal user from a gnome-termnal, it runs fine, turning on dpms. When I use the same script via acpid, I get a permission denied error. At first, I thought it was maybe an selinux issue. Afterall, I had to lear up a bunch of other denies WRT acpi/apm. I checked the audit logs with audit2allow, but there was nothing. I turned on some command logging with the -x option to /bin/sh. Here's what I get in /var/log/acpid when running the script through acpid (IOW, when hitting Fn-F3): [Fri Jul 1 15:46:10 2005] received event "ibm/hotkey HKEY 00000080 00001003" [Fri Jul 1 15:46:10 2005] notifying client 22067[932:932] [Fri Jul 1 15:46:10 2005] executing action "/etc/acpi/actions/backlight.sh" [Fri Jul 1 15:46:10 2005] BEGIN HANDLER MESSAGES ++ pidof /usr/X11R6/bin/X + PID=2678 + '[' 0 == 1 ']' ++ perl '-ne/\x00-auth\x00(.*?)\x00.*/&&print$1' /proc/2678/cmdline + AUTH= + '[' x = x ']' ++ perl '-ne/(^|\x00)XAUTHORITY=(.*?)\x00/&&print$2' /proc/2678/environ + AUTH=/v/home/pete/.Xauthority + export XAUTHORITY=/v/home/pete/.Xauthority + XAUTHORITY=/v/home/pete/.Xauthority + /usr/X11R6/bin/xset -display :0 dpms force standby Xlib: connection to ":0.0" refused by server Xlib: No protocol specified /usr/X11R6/bin/xset: unable to open display ":0" [Fri Jul 1 15:46:10 2005] END HANDLER MESSAGES [Fri Jul 1 15:46:10 2005] action exited with status 1 [Fri Jul 1 15:46:10 2005] completed event "ibm/hotkey HKEY 00000080 00001003" Running the exact same script from a gnome terminal as either root or pete gets the sceen to blank just fine. This worked fine in FC3. Suggestions? Thanks, pete
