The DynamicPM option only changes the power state when the screens are blank (DPMS active). If you are getting changes in power states on AC/DC changes, then something else is messing with the chip, perhaps the bios.

Strange indeed. any more fixes? :) best regards im reopening it, since the behaviour just switched sides, didnt fix it , sorry ok, i can confirm it does work, strange it doesnt change frequency when dpms is called with vbetool, like i was doing. sorry, my mistake. groo@kerberos:~$ sleep 5; xset dpms force off; sudo sh -c 'rovclock -i' Radeon overclock 0.6e by Hasw (hasw@hasw.net) Found ATI card on 01:05, device id: 0x5975 I/O base address: 0x9000 Video BIOS shadow found @ 0xc0000 Reference clock from BIOS: 14.32 MHz Memory size: 131072 kB Memory channels: 0, CD,CH only: 0 tRcdRD: 3 tRcdWR: 1 tRP: 3 tRAS: 6 tRRD: 1 tR2W-CL: 1 tWR: 1 tW2R: 0 tW2Rsb: 0 tR2R: 1 tRFC: 13 tWL(0.5): 0 tCAS: 0 tCMD: 0 tSTR: 0 XTAL: 14.32 MHz, RefDiv: 6 Core: 71.60 MHz, Mem: 0.0 MHz groo@kerberos:~$ sudo sh -c 'rovclock -i' Radeon overclock 0.6e by Hasw (hasw@hasw.net) Found ATI card on 01:05, device id: 0x5975 I/O base address: 0x9000 Video BIOS shadow found @ 0xc0000 Reference clock from BIOS: 14.32 MHz Memory size: 131072 kB Memory channels: 0, CD,CH only: 0 tRcdRD: 3 tRcdWR: 1 tRP: 3 tRAS: 6 tRRD: 1 tR2W-CL: 1 tWR: 1 tW2R: 0 tW2Rsb: 0 tR2R: 1 tRFC: 13 tWL(0.5): 0 tCAS: 0 tCMD: 0 tSTR: 0 XTAL: 14.32 MHz, RefDiv: 6 Core: 300.72 MHz, Mem: 0.0 MHz Edit/Delete Message (In reply to comment #6) > ok, i can confirm it does work, strange it doesnt change frequency when dpms > is called with vbetool, like i was doing. sorry, my mistake. Don't use vbetool. It goes behind the driver's back and messes with the hardware directly. The same is true of other apps and utilities that bang on the hw directly. |
