נושא ההודעה: Arch-XFCE power management problem

Hi,
I use a fully updated Arch/XFCE, among others, to watch movies (on a large external TV connected via HDMI) using VLC.

I use the following startup script to disable pam, among others:

קוד:

#!/bin/bash
 xset -dpms; xset s off
 xrandr --newmode  "1920x1080_50.00"  144.1667  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
 xrandr --addmode HDMI-0 1920x1080_50.00
 xrandr --output HDMI-0 --mode 1920x1080_50.00



Till about 2 days ago I had no problem watching movies this way.

Ever since (as far as I remember after a full system update), while watching movies, every few minutes the movies suddenly stop, and automatically resume (after skipping some frames) after about 15-20 seconds.

From the following journal I suspect the problem is pam related although it's disabled by the startup script.

Please advise!

Thanks

Michael

I've also ran the following test yet I don't know to decipher it:
