total newbie here. My old XP box died last week; bought a used HP 6000 Pro with integrated VGA. Decided to go single boot Ubuntu, had a cd made for me. All was going well. Partitioned the disk as follows:
sda1: 32G primary swap
sda2: 32G primary / ext4
sda3: Extended
sda5: 8G logical /tmp
sda6: 28G logical /var
sda7: 100G logical /usr
sda8: 200G logical /home
sda4: 100G primary /dos
Installed standard from cd, then
sudo apt upgrade all
Then installed Synaptic, added multiverse and restricted repos, Cinnamon, gcc, g++, blender...
And there I hit a snag: blender refused to run withou a gpu. Now, I intended to buy a Radeon and a wide screen with FreeSynch, but I don't have the money yet (unemployed), so I figured why not move the videocard from the XP box.
I tried the card first, see if it would auto-detect. The card is 4.5" format; my new box is 3.5" format, so I had to bend some metal to get the card to plug in. The bios did detect it, and I changed IRQ5 from Intel VGA to Nvidia. Ubuntu was booting until user screen, then froze. So I figured it needed a driver. My old box is Dell Dimension 9200. I believe the videocard is Nvidia GT230 or GT250. Either way, the right package for the driver seemed to be 430.108, so I installed it, and all its dependencies.
When Synaptic finished I got a message that I had to fix something with resume. I had that problem before and managed it by fixing the UUID of my swap partition, sda1; but this time the number was correct. I checked fstab and panicked to see the order of my partitions changed, with comments sayin they were different during installation. I worked hard at restoring the original order of the partitions. Maybe it's not relevant? All the tutorials say fields are separated by a space or tab; nobody clarifies whether multiple spaces or tabs are acceptable. Are they? At the end of the day, I don't think I changed anything important, but when I try to boot with the video card I get a black screen regardless if I'm booting from disk or CD.
Without the videocard I can boot from install cd; but trying to boot from disk I see very fast text messages on the screen, the last of which I think mentions sda1, and then a black screen with a flashing cursor top left.
With the videocard in place, CTRL-ALT-F4 doesn't work for me. Tried it on two consecutive boots. The first boot I hit the 3 keys as the Ubuntu logo came on, and it showed a bit of VGA tex, then went black. Second time I booted it never got to the logo. After a millisecond flash of text it went black and the 3 keys do nothing. Now, without the videocard, the only diff the 3 keys make is going from logo directly to flashing cursor, instead of having to wait a few seconds. I noticed the heatsink on the gpu has a bit of play. I'm willing to give up on using blender. Just want it to work again
sudo apt update
and thensudo ubuntu-drivers autoinstall
just to make sure you have the correct drivers installed. Also, you can run commands to check your disk from there as well so you don't need the CD (that is, if you can sign into the console). – mchid Jul 12 '20 at 02:45
