I do not have any BIOS password. The output of the following commands :
-
[EMAIL PROTECTED]:~$ sudo dellLcdBrightness
[sudo] password for ejvyas:
Read Battery Mode Setting
current: 0
min: 0
max: 7
[EMAIL PROTECTED]:~$ dellLcdBrightness
An Error occurred. The Error message is:
Could not instantiate SMBIOS table.
[EMAIL PROTECTED]:~$
I am a fan of Ubuntu. The brightness was working earlier - I was trying out
a whole lot of changes for tuning and speeding up Ubuntu ....I am sure
something failed. Please help me fix this
Thanks,
Vs
