hi everybody,
i installed a fresh arch to my new acer aspire 1810tz and have a problem with xorg. after logging into my xfce, "top" displays between 80% and 85% cpu load by "X", sometimes for several minutes, sometimes just for short. the xorg logfile gives about a hundred times the following lines:
(II) PM Event received: Capability Changed
I830PMEvent: Capability change
(II) intel(0): EDID vendor "CMO", prod id 4352
(II) intel(0): Printing DDC gathered Modelines:
(II) intel(0): Modeline "1366x768"x0.0 65.56 1366 1373 1408 768 769 772 776 -hsync -vsync (46.6 kHz)
i guess this is what causes the problem, although i'm not sure about that. i do not use an xorg.conf but hal and the "intel" driver with "intel_agp" and "i915" in mkinitcpio.conf MODULES section, as described in ArchWiki for kernel modesetting, maybe there is a relation between this?
greetings!

i've got news...
when starting powertop, the problem occurs immediately, but when additionally running glxgears, it doesn't occur, so i guess it really is a graphics processor powersave state problem.
i would guess that glxgears prevents the graphics processor from going to idle state and trying to save energy.
is there a possibility of selectively supressing pm events? or are there any other ideas what could help?
greetings!
