1) As a non-root user, when I logged on through KDM in runlevel 4, a error message was given:

/dev/dsp can't be opened (Permission denied)

Funny thing is, if I logged on through "startx" in runlevel 3, there was no error message and the system can have sound.

What's the problem?
ls -l /dev/dsp gives:
crw-rw----


2) My firefox cannot be launched. I tried to start it from the menu, but it failed after long busy-launching seen from the task bar. Seamonkey can be successfully launched, but with long launching time. So I guess maybe there is some config problems about my internet browser.


Thank you guys! Hope you can help me out!

PS: SLK 12.1 is amazing^_^

If you add yourself to the "audio" group, you shouldn't get the message about /dev/dsp. Have you tried launching Firefox from a terminal to see if there are any error messages?

Also, try creating a new profile for firefox. Try temporarily moving~/.mozilla to ~/.mozilla.old. Then relaunch Firefox. This will create a new ~/.moziila folder, and a new profile with it.
You can always [mv ~/.mozilla.old ~/.mozilla] to put it back if it doesn't fix it.

I found every time I launched a program, SCIM always started first, which made the process of launching that program quite slow. So, this might be the problem about firefox.

Does anyone also have this problem? How to fix this?

Thank you!!

This sounds like a problem I had.

This issue has been covered many times in even recent threads in this forum. Just to reiterate, the issue is that in runlevel 3 you get added to "bonus" groups as set by /etc/login.defs
As a result, your audio seems to work fine in runlevel 3, but not in runlevel 4 unless you user is a part of the audio group.

should add your user to the audio group. Be sure to relogin that user and then run groups to check if the group is there. While you are at it, make sure your user is at least part of the plugdev group as well to make sure HAL works properly. Also, the lp group is suggested for printing in 12.1 (see the CHANGES_AND_HINTS.TXT).

~/.mozilla/firefox/ is the default location for Firefox profiles. If you mess with the entire .mozilla folder you are also messing with your seamonkey profiles as well. Running firefox -P lets you create a new (and delete or rename) a profile anyways, so you should not have to clear anything out.

If allend's advice on SCIM isn't what you need I first recommend that you check for any lock files under your profile that may be preventing it from opening. It will be called something like .parentlock. If firefox is not running then remove this file. If you have to kill any running instances of firefox first (pkill firefox).

If you think it is a profile problem then by all means try a new profile. As I said earlier, you can simply create a new profile for testing by using the Profile Manager (firefox -P).

Thank you guys!
I've figured out the two problems.

Adding the user to 'audio' group solved the first one. As for the second, it was caused by scim. I fixed by:

chmod +x /etc/profile.d/scim.*
