Created attachment 36179 [details] profiling file of 3 programs making xorg excessive cpu usage I am using linux ubuntu lucid on amd64 athlon xp 3200+ cpu with asus k8v-se motherboard, nvidia fx5200 graphic adapter, 1,5Gb ram When i launch some page on firefox3 like this one http://www.europalms.be/ i can see Xorg taking 80% of the cpu, about 40% to 70% with audacity last version and sun virtualbox reach 30% to 40% on xorg depending the cases. i attached the profiling files for 3 of them. I can tell it is not coming from the graphic driver because i tryed as well on Nvidia legacy 173 and "nouveau" with the same results. It is a new problem i could find a lot of occurence from 3 years on the past which looks like have not really been resolved. I am at your disposition for further tests or logs Thanks and best regards
versions of components: x11 common 1:7.5 linux-headers-2.6.32.22 libdrm2 2.4.18 nvidia-173 173.14.22-0 the problem was exactly same under ubuntu karmic koala with other configuration
xserver-xorg 1:7.5+5
I'm not sure what profiling tool this was from, but it appears to contain very little information about what Xorg was doing.
