I upgraded my Ubuntu 8.04 to 8.10 on last Saturday, and found some problems need help,
1. I have set the CPU frequency policy to be performance in the gconf-editor (apps > gnome-power-manager > cpufreq > policy_ac), however, every time I boot the computer, it always adopts the policy ondemand.
I installed the cpufreq-selector and added the module acpi-cpufreq to /etc/modules, but no helps.
2. Like Ubuntu 8.04, Ubuntu 8.10 uses pulseaudio as the sound sever, but I notice that I can activate only one media program at a time, otherwise, the other program has no sound output, of course, the system sound is also disabled. this problem occurred in Ubuntu 8.04, I just wonder why six months later, Ubuntu 8.10 still has the same problem?
I solved this problem by editing /etc/pulse/default.pa to modify the following two lines
#load-module module-alsa-sink
load-modul module-suspend-on-idle
to
load-module module-alsa-sink device=dmix
#load-modul module-suspend-on-idle
but I got another problem with this modification, I can not adjust the volume with combined keys Fn+F11 and Fn+F12 , this did not happen in Ubuntu 8.04, I tried many times to solve it but still no success.
3. Cheese can be activated normally, but the webcam is still on after the Cheese is closed, the only way to shutdown the webcam is to power off the computer. (The light of webcam is still on if reboot, that is weird)
Thanks for any clues and solutions to these problems.
