Lyd i ubuntu – linuxmint etc på HP laptop

Ut av boksen har jeg hatt problemer med manglende lyd når jeg har installert ubuntu-baserte linux-distro’er på de HP laptop’ene jeg har vært borti.
Løsningen har vært å editere /etc/modprobe.d/alsa-base.conf :

sudo gedit /etc/modprobe.d/alsa-base.conf

Legg til disse linjene:

options snd slots=snd-hda-intel
options snd-hda-intel model=hp-m4
alias snd-card-0 snd-hda-intel

Dette har hjulpet i mine tilfeller, på forskjellige HP laptops, både pavillion dv-7/dv-5 og mobile workstations.

Nvidia display drivere i ubuntu 9.04

Tar denne på engelsk…

For those who have had problems when installing/activating the nvidia display driver in ubuntu 9.04 (jaunty jackalope), here is what have worked for me. It seems there is a permission problem when installing from the “Hardware Drivers” panel-applet,  and for me it lead to the entire xconfig getting left useless.

So, to avoid that you might want to try:

start a new terminal

“sudo -i”  to get in permanent superuser mode

“/usr/bin/jockey-gtk” to start the “hardware drivers” applet , now in superuser mode

Activate your preferred driver and let it install, it will require a reboot.

You should now have the driver installed and working, at least this has worked on 4 different machines for me. On a laptop I was unable to do the install on battery, had to connect it to power. After that everything worked as it should.

Hope this will be of help..
