performance better as root for everthing [SOLVED]

Lexion · 2010-11-09 14:34:25

I've got a Dell Mini 10v. When I run just about anything as user it is really slow. Then if I open the same application as root without changing anything else, it suddenly speeds up.

For example, youtube as user is unwatchable, but as root is fine. I have noticed this behavior in flash, urban terror, sauerbraten, warsow, and glxgears.

Also, youtube has no sound as user, but has perfect sound as root, although I don't really want to run chromium/firefox as root.

In which groups is your normal user? Is it in audio and video and in other groups which are recommended?

See this section: https://wiki.archlinux.org/index.php/Be … tup_groups

I am in and only in wheel, games, network, video, and audio.

As a normal user, you should be in these groups.

The only groups that could possibly have anything to do with speed would be video and audio.
Try creating a new user and, if that works, start deleting config files (starting with .asoundrc).
Also, what does cpufreq-info say (if you even have cpufreq).

I tried creating a new user:

groups test

wheel video audio users

and it was just as good as root. I'll try deleting some config files later, but I have to be somewhere now.

While deleting config files I kinda screwed up my system, so I had to reinstall. But then when I tried glxgears again as user, it was still slow. The only config files were Xauthority, Xdefaults, xinitrc, zshrc, bashrc, and the .config directory. I tried the following:

mv .config .config.bak

Which had no effect. So then I tried the following:

sudo adduser accel
...
Login name: accel
UID: [next available]
Initial group: users
Additional groups: wheel
Home directory: /home/.accel
Shell: /bin/bash

su -l accel -c "glxgears"

And it worked fine. The only thing I could think of was the environment variables. Which worked:

env -i DISPLAY=$DISPLAY glxgears

And now I just prefix chrome, any games, and stuff with "env -i DISPLAY=$DISPLAY" and everything works great.

Thanks for all your help.
