I have not been able to test this fully yet. Just have not had time to do
so.

I have changed graphics from hybrid to discrete in the BIOS, disabling the
Intel card, and
enabling the Nvidia card. That works, X starts and I have gnome desktop.
Still get the occasional
freezing of the system, it comes back and I'm able to resume working. No
hard lockups yet. (From my limited
testing).

I see some kernel messages, time outs for x amount of seconds. I need to
reboot and check on dmesg messages. I can give full dmesg output, however I
have seen some messages that I don't see every time.

It's good that changing setting in BIOS shows X/gnome working. Ultimately,
I'd like to stay away from making BIOS changes every time I want to boot
from Windows to CentOS. Would be nice to have this while in the operating
OS environments. Even if I didn't have dual boot, just having CentOS
installed, would be nice to have the option to change graphics card without
rebooting, and going to BIOS to make changes.

Is going down the primus/bumblebee route, the only way for this? I have not
tried this route yet, as I'm a little confused/hesitant from installing the
elrepo/nvidia drivers, which disabled nouveau drivers. I see from looking
at primus/bumblebee docs on elrepo the config mentions nouveau. Isn't
nouveau disabled from nvidia driver install? What else is needed to convert
to this setup?

Are these some questions I should be asking on the CentOS list also? I
wanted to start here, as it seems most of my issues so far, point me back
to elrepo packages possibly helping. (BIOS changes, nvidia drivers, primus,
bumblebee, main line or long term kernels). I have yet to try anything
other than stock install, elrepo nvidia drivers, and BIOS config changes.
The elrepo drivers and BIOS config have been positive so far.

I have some time tomorrow through Tuesday to do some more testing. Any
ideas or suggestions would be appreciated.

Seems like so far, issues are being able to change from Intel to Nvidia
graphics while in operating environment, and the occasional freezes. I'll
give primus a shot and test, but again, I'm a little confused with the
mention in docs about nouveau. Again, I'll check on those kernel timeout
messages that happen on stdout).

Let me know if I should check anything else or provide other output
commands.

Thanks
Doug
