Hello,
I’m trying to install the Tesla K40c in a HP Proliant DL380g9. HP confirmed it’s supported. I also have an onboard graphics card.
lspci |grep VGA
01:00.1 VGA compatible controller: Matrox Electronics Systems Ltd. MGA G200EH (rev 01)
When I perform a fresh clean install of ubuntu 14.04.3, X works fine. I’m installing the server and then running apt-get install ubuntu-desktop. All is fine after that( I can login via the gui) as soon as I install the driver for the tesla k40C, it breaks X. I get a login prompt but it just keeps taking me to the login prompt(The GUI is not fully loaded.) I’m also wondering why linux is reporting my Matrox card as unclaimed. when running lshw -C display , that’s before and after tesla driver install, yet X works ( I’m pretty certain UNCLAIMED means that a driver has not claimed it yet.)
# lshw -C display

I’m also a bit confused on what the difference is between the cuda__linux.run
file and the NVIDIA-Linux-x86_64-346.89.run file. Ultimately , want to use the onboard for X gui and the Tesla for Computing. Can someone kindly point me in the right direction.

I’ve tried the run method and the repo method
I’m also not seeing the /dev/Nvidia* in section 4.4. Device Node Verification
I do see them after going through the installation. I’ve ran the samples so I know cudo is working but it’s breaking my Xorg server
The linux getting started guide that you linked is a useful resource. I’ll offer some suggestions.
-
Start over with a clean install. The runfile and repo methods of installation are not compatible with each other, which you will discover if you read that guide carefully. History of doing one will corrupt the other method.
-
Get your system running the way you want it (X GUI and all) without the K40c GPU installed.
-
Follow the instructions in the guide to remove the nouveau driver.
-
Install the K40c GPU. At this point, you haven’t installed the driver, so your GUI should still be working.
-
Grab the latest linux driver only for your K40c – the runfile installer, such as this one:
[url]http://www.nvidia.com/download/driverResults.aspx/88814/en-us[/url]
-
Run the driver installer from step 5, but select “no” if prompted to install any OpenGL libraries and select “no” if prompted to modify the xorg.conf file.
-
At this point, if your GUI problems have not surfaced, then you are probably past the trouble. You can then run the CUDA 7 linux runfile installer (not repo method) and simply select “no” when prompted to install the driver.
-
If your login-loop has returned after step 6, try re-running whatever steps you had used (e.g. apt-get install ubuntu-desktop, etc.) to get X desktop up and running originally. You might need to do some force-reinstall or purge reinstall.
Thanks for the reply, although it seems I’m never prompted if I want to install OpenGL or confgiure X, I’m assuming i’ll have to pass it some parameters judging by looking at the source file of the run file, I see a --no-opengl-files
the driver installer has command line help that is available by specifying --help, I believe.
Thanks a Bunch, seems to be working
