I am having a random problem. The workaround is easy, but I have no idea what the root cause is. My xset configuration is being changed at random times to ridiculous values.
DPMS (Energy Star):
Standby: 32 Suspend: 48 Off: 64
DPMS is Enabled
Monitor is On
I run Tumbleweed with the most recent kernel-default and the ATI proprietary driver (using a known workaround to install it). I don’t believe the ATI driver is to blame as the problem also occurs if I remove it and fall back to the native radeon driver.
Running “xset dpms 0 0 0” takes care of it for the session. For some curious reason, xset seems to honor that command better than simply running “xset dpms off”. The problem is extremely random and somewhat rare. It might act up once or twice a week. I would like to find the source but have no real idea where to look. xset seems to have a mind of it’s own and often does not honor other system settings. For instance, if I turn my monitor off and then back on, the system apparently “re-senses” it and adjusts xset accordingly (speculation). But usually, the settings are set to values that could be considered normal. What might cause it to set “standby” at 32 seconds?
