Problem:
In recent GPUs, you may notice that somehow the GPU is getting high utilization while there is no process running. Based on explaination in http://docs.nvidia.com/deploy/driver-persistence/, this is happened because the kernel module is loaded but the GPU is not initialized yet. By default, GPU will be initialized when there is a GPU process start working on it, and then deinitialized when the process is completed.

sysadmin@sap-dl:~$ nvidia-smi

Solution:
We can keep the GPU to be initialized all the time. This is called “persistence mode”. To enable it:
sysadmin@sap-dl:~$ sudo nvidia-smi -i 0 -pm 1
[sudo] password for sysadmin:
Enabled persistence mode for GPU 0000:02:00.0.
All done.

However, this setting will be reset when the server is rebooted. Hence, we will need to set it in rc.local to make it starts during startup.
If you can’t get to the login page (booting gets stuck at “Wait for Plymouth Boot Screen to Quit”) after CUDA driver installation, then it’s probably because the kernel is trying to load xorg.conf created by NVIDIA driver. I got this experience in my laptop that has Intel + NVIDIA GPUs running CentOS 7.

If the above message suddenly comes up in your screen after CUDA driver installation in RedHat/CentOS/Fedora OS, don’t be panic. This is happened because of xorg-x11-drv-nvidia-gl package, which is part of cuda-drivers dependencies. I got this experience in my laptop that has Intel + NVIDIA GPUs. I guess it’s because the Intel GPU is the primary GPU in my laptop, and for RedHat/CentOS/Fedora there’s no a kind of official Optimus technology, like in Windows.

nginstal nvidia driver di fedora 10 ga beda kok kayak versi sblon2nya, tapi bener2 harus login pake root awalnya.
yang agak pusing cuma kalo nginstall nvdia driver yang support CUDA. karna CUDA terakhir versi 2.1 masih Beta, trus SDK nya masih 2.0, dan sebenarnya untuk fedora 9. tapi karna gw bandel, gw cobain aja di fedora 10, dan hasilnya… error dimana-mana, heheh… ga sih, sebenarnya error ntu karna gcc nya versi 4.3 sementara CUDA SDK nya masih pake gcc versi di bawah 4.3 jadi pas di compile error dah… untunglah dengan ubah dikit2 di file2 SDK nya,.. CUDA bisa jalan di fedora 10.. hohoho
Proses instalasi (sebagai root):
1. download NVIDIA’s CUDA Development Tools, yang terdiri dari
di http://www.nvidia.com/object/cuda_get.html
2. Instal NVIDIA CUDA Display Driver dengan langkah-langkah seperti di postingan sblonnya(langkah 2-5).
3. Instal CUDA Toolkit dan CUDA SDK. Untuk menginstal file berformat .run, bisa dilihat Read More …
Awalnya, pengen nyobain desktop visual effect di fedora, kok ga bisa-bisa, eh ternyata driver gpu nya blon terinstall.. hehe. Yaudah setelah ngubek-ngubek mbah Google, nemu petunjuk.
Langkah – langkah untuk instalasi NVIDIA driver
download paket NVIDIA driver for Linux dari
http://www.nvidia.com/Download/index.aspx?lang=en-us
atau gw dapet link langsung buat NVIDIA GeForce 8 series
http://www.nvidia.com/object/linux_display_ia32_173.14.09.html
masuk ke shell mode
# /sbin/init 3
trus logon sebagai root, kemudian masuk ke directory tempat dimana nyimpan downloadan NVIDIA tadi.
install driver-nya
# sh NVIDIA-Linux-x86-173.14.09-pkg1.run
muncul beberapa pesan error, tp bersamaan ada konfirmasi buat ngatur konfigurasi secara otomatis jadi jawab aja ‘yes’ semuanya.
Ok, proses instalasi selesai.. lalu kembali ke window mode
# /sbin/init 5
NVIDIA driver mulai bekerja ditandai dengan munculnya logo NVIDIA untuk beberapa detik dan tiap kali booting logo tersebut akan muncul.
