Can't disable card on Dell L502X - Fedora #578

Closed s0101 closed 13 years ago

s0101 commented 13 years ago

I am running Fedora 15 on a Dell XPS 15 l502x. Bumblebee installed correctly, 'optirun64 glxgears' does fine. However, i am unable to turn off the card because the nvidia module is in use:

su -c 'bumblebee-disablecard'
Password: 
FATAL: Module nvidia is in use.
Error: could not unload nvidia module, leaving card turned on

Thinking GNOME3 / X11 might be using the video card, I edited my xorg.conf.nvidia file to use the Intel graphics. I added Intel as a Device0 and moved nvidia to Device1, as suggested by one forum thread I found.

Section "Device"
    Identifier     "Device0"
    Driver          "intel"
    VendorName       "onboard"
    BusID        "PCI:00:02:0"
EndSection

Section "Device"
    Identifier     "Device1"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BusID          "PCI:01:00:0"
    Option         "IgnoreEDID"
    Option         "ConnectedMonitor" "CRT-0"
EndSection

After I did this, I was able to disable the card (at least it did not complain, I don't really know if it actually stopped using power, it just said "disabling succeded"). However, 'optirun64 glxgears' now failed:

[VGL] ERROR: Could not open display :1

I already reverted the conf file back to how it was, with the disablecard error. What must I do? Has anyone configured this computer correctly with bumblebee? I want to keep the card off unless I am actually using it for some game. I believe GNOME3 can run on Sandy Bridge graphics, I don't know what might be using the nvidia module and keeping it from being unloaded. I am using power management configuration 19 on the l502x list, by some Andy Kwong, which supposedly has card shutdown capability.

Just a note that disabling/enabling is still considered experimental and hence nothing was added automatically (for Fedora) to disable/enable cards.

The main reason why you can't disable the card is most likely that the nvidia X-server is still runing (check with 'ps -ef | grep Xorg'). To stop the server 'sudo /etc/init.d/bumblebee stop' then you should be able to disable the card. But as said disabling/enabling is not encouraged, by me at least, right now.

Please try the new version here : https://github.com/Bumblebee-Project/Bumblebee.

That one doesn't support Fedora (yet)

ArchangeGabriel commented 13 years ago

Yes, sorry, for similar issue I've said to wait for support. Looks like I've forgot to do that here.
