Some programs refuse to accept my password
While using Debian, some programs may ask for your password but refuse to accept a
valid password.
This is a fault in old Debian images previous to September 2012. If you are using an
image with this fault, upgrade to a more modern image or enter the following command
on the command line.
gconftool-2 --type bool --set /apps/gksu/sudo-mode true
Please enter this command carefully, the spaces are important. The command should be
accepted without any response or errors.
I don't know the root password
There is no root password set by default on Debian. You are expected to do everything
through sudo. You can set one with "sudo passwd root" - just make sure you know what
you are doing with a root account.
Sound
Sound does not work with an HDMI monitor
This is caused by some computer monitors which select DVI mode even if an HDMI
cable is connected. This fix may be necessary even if other HDMI devices work perfectly
on the same monitor (or TV)!
Edit the configuration file - see the instructions at R-Pi_ConfigurationFile.
Add the following line to the configuration file:
hdmi_drive=2
This will force it to select HDMI mode.
Sound does not work at all, or in some applications
In Debian Squeeze, sound is disabled by default because the ALSA sound driver is still
"alpha" (not fully tested) on the R-Pi. To try out sound, from the command prompt before
"startx", type
