It might be that ddc reading consumes lots of > CPU, lets see. I have done that, and the previous messages have gone out in syslog, but the CPU problem persists. Now, I get a lot of messages as these: Apr 28 13:04:19 riemann kernel: [drm:KMS:pid1957:intel_crtc_cursor_set] Apr 28 13:04:54 riemann kernel: [drm:KMS:pid1957:intel_crtc_cursor_set] Apr 28 13:04:54 riemann kernel: [drm:KMS:pid1957:intel_crtc_cursor_set] cur= sor off I can contribute some additional data related to this issue: CPU issue appears when: 1- switching between windows 2- changing the focus (with the mouse or keyboard) 3- open a new window Indeed, It seems to be that CPU time of Xorg increases to 100% only when the system has to redraw some window. But when I am typing in a terminal or doing a heavy scroll (for example, recompiling the kernel or viewing quickly a trace file) the system does *not* eat the CPU, and Xorg process only consume about 2-4% of CPU. Here you can see a ktrace taken while I had two overlapping terminals and I was changing the focus between them. The first one ran top -qS and I could see how Xorg process took the 100% while Xorg was redrawn the border of the other window. After that redrawn was done, CPU dropped at 0% again. http://www.mipaginapersonal.movistar.es/web3/jjuanino/kdump.txt Regards --4Ckj6UjgE2iN1+kY Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk+b2OgACgkQFOo0zaS9RnISmgCcCaZNIXoPF2hEpJLAANHQDYaL W9AAn0zXvrarg2uQ3ej/IWwh04HyGoKZ =l4UR -----END PGP SIGNATURE----- --4Ckj6UjgE2iN1+kY--
