However, the last version of lm_sensors (and/or i2c) perhaps needs some fixing to provide a stability for monitored system. Please help me to solve a problem described below. with best regards Pawel Tobis Description of problem: I found a problem using lm_sensors and DPMS power saving. Reading sensor chip measures from /proc/sys/dev/sensors/*/* (by a daemon for example) causes the screen to wake up from a DPMS-powerdown state. It's a problem when I'm using any of these gui-monitors under X, because DPMS screen powersaving simply doesn't want to work. The problem also exists with any of mrtg-kind sensor monitors. Another issue connected with double registering i2c-dev and i2c-proc (if compiled into kernel) may be solved by patching files i2c-dev.c and i2c-proc.c in the kernel tree in the same way as it was done with i2c-core.c, I mean adding #ifdef MODULE and #endif MODULE into the ending module-registration section. I've attached these patches just in case...
