I just installed the lastest version of the Alsa drivers for my Knoppix HD install system (v. 3.3) and now I am unable to login using any non-root account that I have.
When logging on as the default Knoppix user and entering in my password, the screen goes black then returns to the login screen.
I tried creating a new user account with the same group memberships, but I get the same results.
As far as the steps I used to install the Alsa drivers, I used the steps at the following link.
The only thing I can think of that might have made any kind of difference is the following command:
chmod a+rw /dev/dsp /dev/mixer /dev/sequencer /dev/midi
I built the drivers and libs using my knoppix account while su'd into root.
If anyone has any advice, or needs additional info on how to resolve this issue, please let me know.
Thanks for your time!
