    ASUS EB1037 - nvidia 820m - VBios issue - optimus

    Hello,

    I've bought an ASUS EeeBox EB1037 thinking it would make a great HTPC.

    After trying to install ubuntu I've discovered it is an nvidia optimus based system.

    I've tried loads of different ways to get things working but I think the main issue comes down to ubuntu not being able to access the VBios.

    When trying to boot from a LiveCD I have to add "nouveau.modeset=0" to the Linux grub command. That then boots fine. If I don't do that and remove the quiet splash part it hangs at the VBios section.

    To be able to boot all the time nouveau has to be blacklisted.

    The hang looks like this with the Bios error:

    This is also true when using bumblebee

    I get the following error with bumblebee.

    Code:
    kernel: [ 2103.239018] vgaarb: this pci device is not a vga device
    kernel: [ 2103.240424] nvidia 0000:01:00.0: irq 113 for MSI/MSI-X
    kernel: [ 2103.247963] NVRM: failed to copy vbios to system memory.
    kernel: [ 2103.249699] NVRM: RmInitAdapter failed! (0x30:0xffffffff:714)
    kernel: [ 2103.249714] NVRM: rm_init_adapter failed for device bearing minor number 0
    Any ideas how to get past this step so I can somehow try and get the nvidia graphics working?

    Edit: I should add that I am using ubuntu 14.04. The things I had tried were various nvidia drivers (319, 331, 337) with and without bumblebee. prime-switch and bbswitch fail and the issues all seem to be around the vbios problem.

    I am trying the same - but can't help much.

    I tried 14.04 64 bit server, and 14.04 64 bit desktop. Both did hang in early phase of USB boot, just gray screen and nothing else. Then I noticed that in BIOS (or exactly speaking, not in BIOS but UEFI) has options to define which operating system is used, and ACPI options. I changed operating system to Android (instead of Win7 or Win8), and changed the ACPI to "PCI" if I recall right, without understanding what I did. After that I tried to install old version, 12.04.3 32 bit desktop, and it seems to be OK, just done and boots and looks normal (except that initially it shows ugly black-white striped display)

    But I do not like the idea of starting with something old, and it also does not recognize the WLAN chip.

    Did you have to modify the UEFI options, or did you get it up with just that GRUB parameter?

    I did not yet have time to try 14.04 after the two ACPI modifications were done, will try tomorrow.

    I can get ubuntu 14.04 to install fine in EFI mode.

    You need to add "nouveau.modeset=0" to the grub linux command for the LiveCD and then also on first boot or it will hang. If you remove "quiet splash" you'll see exactly where it hangs. That should get you to the desktop. Once you're there add "blacklist nouveau" to /etc/modprobe.d/blacklist.conf and ubuntu should boot fine.

    Then you can try to install nvidia drivers....!

    I've read around that there's some patches for similar issues where the vbios isn't copied which is down to an ACPI/EFI/CSM issue.

    I also changed a few things to PCI mode and back. Tried various combinations in various menus in the EFI to set it to Win7, Win8, Android, Other OS. Can't seem to find the right settings to get the vbios to copy.

    OK, and thanks for the advice. Now I am in the same situation. I resetted all UEFI settings to default (except temp boot device), and got the same hang if I did not disable nouveau, and got it up by disabling it.

    This is partially good for me, because I was planning to buy one more of these boxes, so that the first one will be used only as a web server and SSH hopper (no windows, just text), and the other then with graphical interface. Thus, this would be OK for the server. It is small, very silent and does not get warm at all.

    And it might even be OK for the other use without the nvidia, because the other one is a "kitchen laptop" used by all the family for simple and mundane things like checking public transportation timetables, reading news(papers), weather, recipes, and all such stuff which seems to work OK also without nvidia - even if it is a bit stupid.

    I've given up for the time being and stuck OpenElec on and I'll just use the Intel graphics until I get the nvidia working.

    Pretty sure it's an nvidia driver issue but my post on the nvidia forum is coming up as "hidden" which is irritating.
