X freezes when bumblebeed has started and switched off the card using bbswitch #137

I have the same issue as @MrBollie. With bbswitch installed Xorg server cannot start. Laptop hangs on attempt to start Xorg (I have tried it using @MrBollie workaround works, but after starting proper desktop environment and using My spec:

Sorry. I have already uploaded it according to readme on GitHub, but did not paste any reference here. Below is a link to launchpad. |
@sodar Can you boot with See also the discussion in Bumblebee-Project/Bumblebee#764 (comment) |
Thank you @Lekensteyn. Adding However after running Here are the logs from |
Please make sure your version of Bumblebee has the latest patches available in the develop branch. There are fixes for the module loading/unloading. You can check that with the maintainer of your distribution. |
I have installed bumblebee from develop branch (package |
I have the exact same machine and after a lot of tries have been able to get it working as per my need. See if the documentation at http://hemenkapadia.github.io/blog/2016/05/07/Ubuntu-with-Nvidia-Bumblebee.html helps you. |
I have a similar problem with only bbswitch enabled. I can not load the bbswitch module at boot without gettting the Frozen X. Also if I have bbswitch module installed, my system will not restart. Running 4.7 Kernel of Archlinux. Laptop Asus GL 552VW |
sorry for my poor English. I have a similar problem that if I turn my card off, it will freeze when I try to get access to my gnome. So, I need to get my card on before I login, and turn it off afterwards. |
Hi there, I'm still using the GTX960M as in my initial post and worked around this issue by starting bumblebee after X is running. Now, I have another issue: gnome-session (or whatever) is now causing the system to load the nvidia module. And while this is loaded, you can start bumblebeed, but bbswich won't get active. I've recently installed a laptop the same way. It features a Quadro K2000M and I was quite amazed, that everything works perfect there. You can start bumblebeed before X and gnome and bbswitch switches it off properly. No issues or anything. So, I presume, we have an issue with how GTX960M is being disabled. It seems like it's not "switched off enough" to prevent the system from loading the nvidia-module, which leads to a hanging system. As far as I understand it, bbswitch is a "convenience layer", offering a simple interface for card-specific ACPI calls. If I'm right, is there a way to check out, if there's "more thorough" ways to disable GTX650M, so nothing will try to load the nvidia module? |
@MrBollie "Disabling the GPU" is different from "prevent a program from loading the nvidia module". The former is done by bbswitch or nouveau. The latter has multiple possibilites. The most reliable method is probably blacklisting or aliasing the nvidia module as done on Ubuntu. You might want to check the develop branch. |
Ok, it seems that I've found a solution for my GE62 6QC featureing said GTX960M.
I did a systemctl enable bumblebeed and so when the system boots up, bbswitch correctly disables the card, gdm starts and I can log into gnome3. So everything is now working as intended. |
Since it's working with a workaround from Bumblebee-Project/Bumblebee#764, I'm closing this bug. Have fun with more battery power! |
I'm not sure, if X is trying to add the card nonetheless and then fails. What helps is
and then let bumblebeed switch in on, when it needs it.

OS is arch, NVIDIA card is a GeForce GTX 960M
