Hi, I am running (up to date) Debian unstable on my laptop, it has a Radeon IGP 340M graphics chip. For the last month or so I am seeing the Xorg process gradually gobble up more and more CPU, up to 30/40% and in some cases 99%.
Even X on its own seems a little sluggish, e.g. when I change windows the gnome icons take a fraction of a second to appear in the new window. But the big CPU problems are seen when I run mozilla-firefox, since usually when I kill firefox Xorg recovers. I don't see any messages in logs that might explain the behaviour and I can't find any related bugs filed against Xorg. Here is the output from the top of top: top - 12:41:40 up 2:56, 4 users, load average: 0.87, 0.45, 0.99 Tasks: 98 total, 3 running, 95 sleeping, 0 stopped, 0 zombie Cpu(s): 40.7% us, 4.8% sy, 0.1% ni, 52.8% id, 1.2% wa, 0.1% hi, 0.3% si Mem: 744112k total, 731812k used, 12300k free, 134736k buffers Swap: 997880k total, 108k used, 997772k free, 239776k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13112 keving 17 0 130m 50m 16m R 34.7 7.0 2:04.21 firefox-bin 12761 root 5 -10 65052 13m 8108 S 10.1 1.9 1:12.19 Xorg 12933 keving 15 0 31756 13m 8596 S 0.2 1.9 0:18.06 gnome-terminal 12935 keving 15 0 44704 7344 5864 S 0.2 1.0 0:02.15 gnome-cups-icon (Hope that shows up OK) Does anyone have any idea what bug this might be? Or clues on how I can track it down further? I don't really have enough information to file a bug report yet .... Thanks for any advice / help Kevin
