My laptop is Acer Aspire 4745G with dual graphics Intel/AMD. Discrete card is Mobility Radeon HD 5430/5450/5470. I'm using Ubuntu 13.10 now.
One day I mentioned that my discrete AMD graphics card is not working, after some googling I found a way how to check it and command
fglrxinfo gave me X Error of Bad Request. And so started my big quest for trying to make it work.
I tried so many ways from Google but no one of them really helped - I still can't use discrete card. I wouldn't even want to be able to switch them - I just want a discrete one work.
The last one I tried is installing driver from official site. Ok, so I installed it with sudo
sh ./amd*.run, it processed and gave me DKMS error in the end or smth like that. After that I rebooted and got a message that system couldn't detect drivers and so on.
So my question is:
- how do I install drivers for my graphics card now, in 2014?
