Public bug reported:
Just upgraded to Xubuntu 14.10, had issues with fglrx (see
http://askubuntu.com/questions/552795/xubuntu-14-10-upgrade-issues-with-
fglrx), went back to radeon drivers. Now it looks to be OK, however
after locking the screen using xflock4 and unlocking, I get these three
processes using a lot of CPU (this is on 4-core Phenom II X4 N950):
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1572 root 20 0 262892 56672 26480 R 89.7 1.4 6:48.70 Xorg
5025 usr 20 0 312116 11336 4632 R 36.9 0.3 0:17.42
xfce4-volumed
5036 usr 20 0 327328 10556 5760 S 31.5 0.3 0:13.38 xfsettingsd
Additional information:
- Killing and restarting xfsettingsd and xfce4-volumed resolves the issue until
next sleep cycle
- When running only xfce4-volumed, but not xfsettingsd, the issue does not
appear
- This can be reproduced always. ATI Radeon Mobility HD 5650 video card
- The CPU usage does not seem to go down after a while
- If I got it correctly, it looks like some other processes are also going to
high CPU usage after killing xfce4-volumed. I think I saw xfce4-xkb-plugin
going to 95% CPU usage
- The issue happens before unlock, i.e. locking then pressing a key to get a
login dialog, then switching to vty1 and doing a top yields the above
Not sure what else I should check / post that can be useful for
troubleshooting, let me know.
