i'm using a really old pc right now. when i try to install nvidia drivers for this graphics card (8600m gt) after reboot ubuntu goes for a blinking cursor with black screen. after hours at forums went to root shell deleted and reinstalled 2 reccomended drivers (340 and 304) still boots black screen. only nouveau display drivers boots to ubuntu gnome but it's pretty laggy.

so i'm thinking about this graphics card not working well probably after years but that much? i can't even watch videos at 360p. my goal is using simple graphic programs and coding until my normal pc fixed

also i did a fan cleaning clean and apply new thermal paste and temperatures are near 55c.

do u have any reccommendation? i'm using ubuntu 16.04

edit:i clean installed 18.04 64-bit it didn't help. after installing nvidia-340 driver now it stuck on a black screen after reboot.

output of command mokutil --sb-state

EFI variables are not supported on this system

output of command lspci -vnn | grep VGA

output of command ls /sys/firmware/efi/

nvidia-340 driver didn't work for me. i tried different versions too. it just stuck on a black screen after installing any nvidia driver. i used nomodeset when installing ubuntu. 5-6 times reinstalled drivers and os today.

i also have that output ubuntu-drivers devices

== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==

i think i'm using xserver-xorg-video-nouveau

  • What was the previous working version of Nvidia driver for 8600M GT? Please edit your question and post the output of these commands: 1. ls /sys/firmware/efi/ 2. mokutil --sb-state and 3. lspci -vnn | grep VGA – Marmayogi Apr 05 '19 at 18:22
  • i can't tell which nvidia driver worked before, it was years ago. i just installed ubuntu this pc after years. thanks for reply – – Cyclone 1400 Apr 05 '19 at 19:22
  • 18.04 is latest and you are good! Only problem could be that your machine is not configured for EFI. You better prepare a bootable USB stick with “Partition scheme” to “GPT” and "Target system” as “UEFI (non CSM). You may use Rufus to prepare USB stick. BTW, what was the output of command ls /sys/firmware/efi/? – Marmayogi Apr 05 '19 at 20:01
  • You may try GeForce Nvidia-342 Driver. If 342 fails, then you try Nvidia-100 released on 2007-Jun-8. If you have further questions, please let me know. – Marmayogi Apr 05 '19 at 20:02
  • Please give us the output of lshw -c video so that we can find out which driver you are using. The nvidia-340 driver should work for you, according to https://www.nvidia.com/object/IO_32667.html – ejjl Apr 05 '19 at 21:25
  • @Marmayogi i dont have windows installed at this pc so i cant use rufus now – Cyclone 1400 Apr 05 '19 at 22:56
  • Please refer this: How can I change/convert a Ubuntu MBR drive to a GPT, and make Ubuntu boot from EFI?. You need not worry about Rufus preperation, now. Nevertheless, you need one in future for troubleshooting. Please post the result of MBR to EFI conversion. Good luck! – Marmayogi Apr 06 '19 at 02:34
  • You can preapre bootable USB stick for Ubuntu using startup disk creator. Refer Bootable flash drive for ubuntu using "startup disk creator". If startup disk creator is not installed on your system, then use usb-creator-gtk package to install from command line as sudo apt-get install usb-creator-gtk. Or else, use Ubuntu Software GUI tool and install startup disk creator. – Marmayogi Apr 06 '19 at 03:22
  • @Marmayogi i just gave up on this pc after trying to efi conversion. read tons of guides, 0 results. i think i'm gonna use this pc with that lag for a while. thank u for replies! :( – Cyclone 1400 Apr 06 '19 at 11:31
  • Please hold your horses! You try to prepare a bootable USB stick for ubuntu using startup disk creator and try to install Ubuntu 18.04 afresh. Make sure that you follow two parameters: 1. GPT partition scheme and 2. UEFI (non CSM) while preparing bootable USB stick. Please don't give up! – Marmayogi Apr 06 '19 at 11:41
  • @Marmayogi so i prepare my usb stick to GPT with gparted then i use startup disk creator with xubuntu 18.04 (i decided to switch to xubuntu for this pc). I think it WORKED! i can see i am using nvidia-340 drivers at additional drivers. videos and programs working smooth. i don't know how to thank u after two days on it Marmayogi! – Cyclone 1400 Apr 06 '19 at 13:19
  • I am very very glad that your problem is resolved! Good Luck! – Marmayogi Apr 06 '19 at 13:23
