I have a HP Pavilion 15-n061sr (ENERGY STAR) laptop with 2 videocards: Nvidia Geforce 740M and Intel 4000 HD. I installed Ubuntu 13.10 x86_64 and Bumblebee by following these instructions: https://wiki.ubuntu.com/Bumblebee#Installation
Also installed nvidia-319-updates, nvidia-settings-319.
When I try: optirun firefox
, I got error:
[ERROR]Cannot access secondary GPU - error: [XORG] (EE)
[ERROR]Aborting because fallback start is disabled.
In /var/log/syslog
I got following error:
HP-Notebook bumblebeed[3064]: [XORG] (EE) HP-Notebook
bumblebeed[3064]: [XORG] (EE) **Invalid isolated device specification**
HP-Notebook bumblebeed[3064]: [XORG] (EE)
I tried nvidia-331, nvidia-331-settings, but with this packages I got same error. In google I found no mention of this error.
