 |

hello helpful people.
i have a strange problem (don't we all)
something has happened to my main user account.
a few days ago, suddenly (i had an xfce session open for a couple of days) firefox slowed down. when i opened a new tab it took minutes. i have been troubleshooting ever since, and i know the symptoms but not the cure:
many (but not all) new X windows and tabs take a long time to open.
scrolling, resizing, and animations inside windows are OK - glxgears is fine.
console apps are fine (i can crunch video at 40fps while i wait for firefox to open a new tab)
it's the same in gnome and xfce, i've restarted the computer twice, and checked all my partitions.
but within my Xwindows session, another user is fine.
example:
after starting and killing firefox a couple of times to make sure it's not disk/cache trouble, i type time firefox-bin into an xterm window, and close the firefox window as soon as it appears (i have the homepage set to blank, so it's not an ip/dhcp issue)
| Code: |
radagast /:time firefox-bin
real 0m42.095s
user 0m40.846s
sys 0m0.177s
|
as another user (su tempuser), in the same xterm:
| Code: |
tempuser /$time firefox-bin
real 0m3.466s
user 0m0.859s
sys 0m0.078s
|
and another app, chosen almost at random:
| Code: |
radagast /:time ghex2
real 0m37.326s
user 0m35.287s
sys 0m0.134s
|
| Code: |
tempuser /$time ghex2
real 0m0.740s
user 0m0.268s
sys 0m0.011s
|
the console doesn't give me any clues. obviously i could leave all my years of customisation and rename myself tempuser (hey is there anyone called that on the forums?), but there must ... be ... something ...
if you don't know the answer, do you know a way of tracking what files an application is referencing as it touches them, so i can look for the bottleneck?
thanks.
andrew
ps i don't have any reiserfs partitions, and there doesn't seem to be anything wrong with my glxgears |

hi, since this is a one user problem must be something on config files.
If top didn't show any special activity on a specific app, then must be something that are trying to read some config file and found some error that goes unhandled. You say you are using xfce. Try to move .config/ to .config_old/ and start a session. Or, since it starts with firefox, do the same with .mozilla dir and check for results. |

good suggestion...
but it happens in xfce AND gnome,
and it happens with firefox AND ghex2
so i'm trying to work out where to start with the configs.
maybe i'll do it the other way round - copy my config files to tempuser until it goes wrong.
this morning's job...

alright!
the problem was
.fonts.conf
i've renamed it, and everything starts ok again.
all my fonts even look ok, so who knows what that file was doing??
thanks RuiP |
