Hello:
I’ve got Intel4600+ nvidia K1100M in my laptop. I’ve installed bumblee in my openSUSE 13.2 X64 OS. I noticed that the default GPU is intel4600. I am just wondering how can we make nvidia K1100M as default loaded GPU? Most of my application need dedicated GPU for running.
thx a lot

my notebook has the same HW (Dell Precision M4800)
in this case if you want to use exclusively the Nvidia check the Bios
in my Bios I can disable the Optimus (Switchable Graphics) and after that only the Nvidia will work
for this probably you may need to remove Bumblebee
Thanks a lot for such kind advices…
I checked my Dell M3800 BIOS, but unfortunately, there is no any option that I can switch off Intel-4000 integrated card…
oh, so you are having the m3800 (BTW do you use the 3200x1200?)
it seems from the M3800 Owner’s Manual that there is no Video Option in the BIOS Menu…
most probably it mean only Optimus SW control (via Windows or Bublebee), than you have to run the needed application with Optirun to use Nvidia…
I’m running 13.1 with kernel from 13.2/standard repo, sometimes I try kernel/stable/standard, if I use the 13.1 kernel the SD card reader don’t work but, if I’m not wrong, the old kernel loaded the nouveau driver by default
I was reading, some time ago, that from Kernel 3.13.xx, don’t remember the exact version, Optimus support was added and by default was loading the i915 driver
I don’t know if can be a good advise or if it is possible to try the old 13.1 kernel after removing bumblebee…
yes, my resolution is very high, but I use xrandr to scale the screen otherwise fonts in many application are very small.
I used 13.2 before with bumbleee, but it doesn’t work properly: the optimus nvidia is also down for no reasons. And I have to give it up and use 13.1
Probably it is not good to change the kernel, since most program are based on this version, and it may lead to unstable of the system.
Do you have any idea whether we can add some option to Grub and turn Intel 4600 off?
Thanks a lot

If the BIOS does not give the option. I’m not sure you can do it with a kernel parameter .
It appears that the Manufacturers are removing the option form the BIOS. Some machines have it some don’t. It makes little sense to me not to have it. It’s bad enough that they sell you a frankenvideo machine of dubious design they make it impossible to configure it the way you want it. Add in the terrible driver support for non Windows users and personally I would not touch a optimus machine with a 10 foot pole. The real problem is that the 2 dissimilar GPU’s are wed some way at the hardware level. <endrant>
If Bumblebee does not work then I’m at a lose
Indeed, it is very annoying that Dell didn’t provide such option for BIOS.
my Bumblee works for most software, but some of them failed such as with following messages:

Where is this from and which Version?
Did you try it with another (stable) Version?
yes, I also tried stable version 1.9.1, and the problem is the same.
Previous old version bumbleee works fine, the problem occurs after I update it to latest version. It happen to both opensuse 13.1 and 13.2…
