ubuntu 15.04 not supports Nvidia driver with hybrid Gcard notebook.

[KOSKERS]

Hi.Every one
I have installed ubuntu 15.04 64bits kernel 3.19
Using additional driver function can not boot the ubuntu successfully. Black screen in ubuntu login UI with login sound when using nvidia card.
When i change to use bumblebee, booting ubuntu is normally.But if i use nvidia card to play dota2. Steam gives me error.


Game update: AppID 570 "Dota 2", ProcID 3238, IP 0.0.0.0:0
ERROR: ld.so: object '/home/koskers/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.


When i test the bumblebee, it seems that right.
koskers@koskers:~$ primusrun glxheads
glxheads: exercise multiple GLX connections (any key = exit)
Usage:
glxheads xdisplayname ...
Example:
glxheads :0 mars:0 venus:1
Name: :0
Display: 0xe605e0
Window: 0x4600002
Context: 0x2226fd0
GL_VERSION: 4.5.0 NVIDIA 346.47
GL_VENDOR: NVIDIA Corporation
GL_RENDERER: GeForce GTX 765M/PCIe/SSE2




Help me. plz. Thanks a lot.
BTW:Neither using 340 nor 346 by active additional driver function was not able to login in ubuntu.

Thread moved to Ubuntu Development Version.

All threads and queries regarding 15.04 belong here. It is not released yet and still under development. For a smoother ride, or if you installed this thinking it is the 'latest and greatest' so it's the one to go for, I suggest you try 14.04 LTS. If you installed 15.04 intentionally, know your way around already, are willing to go on a learning curve and are willing to test and possibly work your way through breakages and bugs, by all means, carry on. Good luck.

[KOSKERS]

Thanks for quick replying. Your words is right.
Is there any resolution for me to deal with that?
And following your word, will 15.04 resolve this problem unity 2015/4/23,right?

My advice is to change video driver. You have a much newer video adapter than me. I have a GT220. And I cannot get nvidia 346 to build on the 3.19 kernel. Even nvidia 340 gives me crash reports as Ubuntu loads to the desktop. But nvidia 304 works fine.

I am starting to wonder if Nvidia has dropped support for my card but that cannot be the situation with your card. These things can get fixed over time but the issue with proprietary video drivers is that the Ubuntu developers cannot fix things. They can only be fixed by the owner of the software and in this case it is Nvidia.

From my own experiments I found that changing drivers sometimes got messed up with Additional Drivers actually failing to change the driver. I had to purge the first nvidia driver before I could install another one. So, just in case that happens to you, here is the code.

sudo apt-get purge nvidia*

Ubuntu will still load as it will revert to using an open source driver.

Regards.

Thanks. But open source have suck performance. it can not run dota2 smoothly.
Thank you indeed.i think i have to wait for ubuntu company resolve this problem by recent updates.

All good, but as grahammechanical mentions:

... so you could be waiting awhile ...

well i put it working today, the problem is with libdrm libs, reverting all of them from 2.4.59 to 2.4.56(from trusty resolves the issue) i lock this libs in synaptic untill the someone resolve this.

using default kernel, nvidia-349 from ppa:mamarley/nvidia

@grahmanmechanical
nVidia made a lot of somewhat newer cards legacy. It looks like your GT220 is legacy with 340.xx
