nvidia-prime (Ubuntu)

Bug Description

System : Ubuntu 14.04 Trusty Thar Alpha 1
Package : Nvidia-prime 0.5.2, nvidia-331
Desktop : Unity or KDE, both malfunctionning

What I expect :

- Relogging after have choose the nvidia discrete card in nvidia-settings, and play my games on steam better than with my IntelHD4000

What I did :

- I installed nvidia-prime and all the needed package with the nvidia-331 drivers
- Choose "Nvidia GT740M" in Nvidia Settings for the next reboot/relogging
- Log out and log back, as I was ordered by nvidia-settings

What happened :

Bug : Unity doesn't run, because no OpenGLX
KDE is running but without any visual effects because of no OpenGLX.
Steam doesn't run.

Hope that will help you.
The error is : extension GLX missing from screen 0
I think the nvidia driver erase the intel-nouveau configurations'files, so I don't have glx

prime-offload.log reports that "the nvidia kernel module is not is loaded". This is the problem.

I have the solution for this bug !


- In fact, the nvidia-331 driver erase the intel's driver configuration's files, that's the cause of "GLX extension missing on screen 0" and the unity's bug.

- So we need to install nvidia-prime and nvidia-331. Don't log out !!!!

- run terminal and execute : "sudo apt-get install --reinstall libgl1-mesa-glx"
this commande reinstall the configuration of intel's HD4000 driver.

4) - Then reboot your computer

- with this command, intel's driver seems to be correctly configured, unity is running, kde too, openglx is working and I can switch between this two cards, the discrete nvidia-card is perfectly working, and nvidia-prime too.
