Toshiba Satellite Pro A300: Fn+F6 & Fn+F7 (screen brightness) not working

[m654321]

[size=1em]Just to add that the Fn-key combinations for screen brightness, or other 'Fn features' didn't work on the Toshiba Satellite Pro A300 in LL2.8 either.[/size]

UPDATE 1
[size=1em]The good news is I've got the 'brightness keys' to work, following a further fresh install of LL3.0, which was used to overwrite the previous version.  [/size]

[size=1em]I appear to have narrowed the problem down to the presence of the proprietary ESET antivirus package for Linux that I use, i.e. eset_nod32av_64bit_en.linux. Without the antivirus installed, the Fn+F6 & Fn+F7 appear to function in LL3.0, but not in LL2.8. So well done the LL-team, with this aspect of Toshiba interface compatibility with LL3.0, at least for the screen brightness issue.  As I'm not dual-booting with Windows OS, I'll probably be fine without an antivirus.  Instead, I'll look at whether ClamAV, from the LL repository, is compatible with the functioning of the 'brightness keys'.  I'll give an update on this later, here on this thread.[/size]

[size=1em]Interesting to note that the 'brightness-keys-incompatibility' with ESET, doesn't occur with setups (1) to (3) in signature below. Trawling through the internet shows that the 'fn-key issue' is a problem commonly associated with Toshiba.  Apparently, Toshiba haven't produced an Fn-interface that's compatible with Linux, though an open source version, called Toshset, does exist - synaptic package manager  shows that it's installed by default in both LL2.8 and LL3.0.  However, when I type Toshset in terminal, I get the error message "required kernel toshiba support not enabled" (in both LL2.8 & 3.0) - a few searches on the internet shows that this too is an often-reported problem. [/size]

[size=1em]I'm going to mark this as solved, as I've found the source of the Fn keys problem, even though I'm unsure how to resolve this in the presence of ESET software. Instead I'll just take evasive action, avoiding ESET-use altogether, on this Toshiba laptop...[/size]
