Have you run fc-cache as root, to create the font caches in /var/cache/fontconfig ? Matthias Clasen : Yes, I do like $sudo fc-cache -f -s -v. and many cahce.2 files are in /var/cache/fontconfig.

Odd, I don't. Dan do you have any font directories with cache files, where the fonts have been moved somewhere else ? Can you see if removing all font cache files and doing a fc-cache -f as root makes a difference ? I'm wrong, I though I had it installed (I had to cancel the yum transaction to leave for work) but I actually don't. I'll let you know how the new version works for me when I reboot. Created attachment 123673 [details] Using attachment 123232 [details], strace file.

Bootup is ok, but from login->desktop is the slow part.

Compare the size & time from the previous comment with it now (30 minutes later, after launching evolution, terminal, and firefox among others): Before 2nd Firefox launch: -rw------- 1 dcbw dcbw 7116077 Jan 26 07:00 /home/dcbw/.fonts.cache-2 After 2nd Firefox launch: -rw------- 1 dcbw dcbw 7333165 Jan 26 07:01 /home/dcbw/.fonts.cache-2 This is _not_ the first time I've launched firefox this login session, the first time was to file the above comment in this bug. So it's regenerating the fonts.cache-2 file on each launch of FF in this session. Seems to do the same thing for every other app too. Killing ~/.fonts.cache-2 seems to have cleared up the problem for me. I just independently discovered the same problem using KDE. Everything was extremely slow and looked like even starting konsole was doing a lot of disk activity (30 seconds). Doing an strace I realized that it was loading enormous amount of fonts. Looking at my cache file it was 720MB, yes that is true. I am investigating now if this is just resolved by removing files or not but there are a lot of people out there complaining of major slowdowns and thinking it has to do with kernel debugging options. I hope that fontconfig-2.3.93.cvs20060131-2 addresses most of the remaining fontconfig problems. Do people still see this problem with fontconfig >= 2.3.93.cvs20060207-1 ? If so, does it still happen after regenerating all cache files ? I haven't seen any signs of this for a while. Should we assume it is fixed now? Yes |
