Hey guru's i'm having problem with brightness control on my lappy on W8 with AMD crappy drivers :bang: they broke it since beta 13.2 i think and its aint fixed even on 13.8 B2 and i tried W 8.1 and OMG its even broken on M$ stock driver then i tried the preview driver with no luck :wanker: so now the latest driver with working brightness control is 13.1 :nerd: any help appreciated
i don't have switchable graphic my problem is just brightness control wont work with new AMD drivers :bang:
If you were to check the site it would give you an idea on how to fix your issue . Very likely that your FTC value is screwed up. Check the manual section & the database for a value that could potentially fit you.
I had the same problem, nothing can fix it. I ended up reinstaling new OS and brightness slider was back. Try this maybe it will work : http://superuser.com/questions/308721/windows-7-brightness-slider-suddenly-gone
i just installed the OS yesterday the funny thing the brightness control working normally with system generic driver but as soon i update the driver via device manager to M$ driver or AMD windows 8.1 preview driver it will stop working as soon as the driver get installed I've had the same problem with W8 the only driver was working 13.1 and previous but since 13.2 beta AMD broke the brightness control :bang: i found crappy workaround by changing the brightness then turnoff the backlight fn + f6 will change brightness but its sucks uke2:
