the big problem now is the battery information. i really have no idea
where to look for it. it is really dangerous to us a laptop without
knowing when the battery will die.
I am rather curious what application you are using to get battery
information that requires it being root.
/proc/acpi/battery/BAT0/state is 0444 on my netbook/laptop since
forever. I just use a bash function to parse it and display it on my
${PS1}.

my laptop is thinkpad t61, and i do not have /proc/acpi/battery/BATO/state... :(
now i have a damn wired good news. all the problems i talked about are
gone. :) i can access my usb disk, i can see the battery info.
yesterday, after i have joined those groups, i did not restart my
system. i just exit X, and log off, then log on, and i did not able to
access those resources. but today, after a cold start up, all the
problems are fixed without touching any configuration.
i think this is just a group and permission issue.

Logging out of and back into X should be enough for any group changes to take effect. I wonder if it could have been a module loading problem. -- Neil Bothwick A great many people mistake opinions for thoughts. -- Herbert V. Prochnow signature.asc Description: PGP signature

[gentoo-user] normal user do not have access to usb, and many other things
hi, i usually use my linux system with root account. i think it is not good, so i created a normal user account for myself. but i found that i cannot access many system resources, like usb disk, battery informatiion, etc. i am already in these groups: disk,wheel,audio,video,usb,haldaemon,plugdev. now, i cannot get notification when i plug a new usb device. my battery gadget says battery information is not available. all there stuffs works fine if i log in with root account. -- Best Regards, David Shen http://twitter.com/davidshen84/

You only have yourself to blame I'm afraid ... When you login to xorg using a root account some configuration files become owned by root. A normal user can no longer access them. Most desktops should be clever enough to allow users to create their own configuration files in their home directory - but I am not sure how you have yours set up. Either way, to login in X as root user is a *very* bad idea from a security perspective. Personally, I recommend to reinstall Gentoo from scratch, instead of messing up with access permissions on config files. It would also teach you to follow the Gentoo handbook to the letter (which asks you to set up a plain user account during the installation). ;-) -- Regards, Mick

Maybe someone else more experienced in KDE can explain what happened and why the particular functions are now not available to plain users, or if you have another machine which has been running properly you could compare and contrast access rights between the two systems. Meanwhile, just as a test, you may want to logout of X, move the /root/.kde4 folder and /home/user/.kde4 somewhere else, then restart X as a plain user and see if these functions are working properly now. If not then I suspect the problem is not with these user specific configuration files but with the system KDE or X files.

Depending on your specific USB device you may need to edit UDEV rules to set proper permissions on the device node. For example I had to do that for normal users to read my digital camera.
