Problem installing CUDA Ubuntu 14.04 LTS

Problem installing CUDA Ubuntu 14.04 LTS

My Pc is DELL Precision T1700 : Memory : 15.6 Gio
Processor : Intel® Core™ i7-4770 CPU @ 3.40GHz × 8
graphics card : Gallium 0.4 on llvmpipe (LLVM 3.4, 256 bits)
Type OS : 64 bits
Disque : 122.9 GO

I need to use CUDA 6.5 : I stopped the X server , I install Cuda ,
the installation is done corrcectly with any error message.
After that, the screen become Black with white blink and I can’t do any think ( ctr+alt+F1 don’t work).

My question is what is the problem of the install? if it’s a problem of Pc, what is the best configuration needed to install CUDA??

Do you have an nvidia GPU? If so, you may have a conflict with the nouveau driver.

this is the description of my graphics card:

how can I resolve the conflict with the new driver???

If you google “ubuntu disable nouveau” you’ll get lots of examples.

Something like this, as root:

stop lightdm

then edit /etc/modprobe.d/nouveau-blacklist.conf
with the following:

blacklist nouveau

then do the following:

update-initramfs -u

and then reboot

then reinstall the nvidia driver

then reboot and restart X
