Hey all, just got a Geforce 5070 to replace my 2070 from years ago. Ubuntu’s been pretty smooth sailing for me until now, and I’m not exactly the best at navigating this stuff.
When Ubuntu starts to boot, the GPU stops outputting display to my monitor. As though it doesn’t detect the new GPU. I tried putting the 2070 back in and downloading the 570 drivers but it didn’t change anything. I found a tutorial for what seemed to be my issue that asked me to change the kernel, but halfway through the tutorial, commands that worked on their machine started failing on mine. I wish I’d documented what the error messages were because when I went to poke around more today, I got a message about kernel panic and can’t even boot with the 2070. Where do I go from here?
You did plug in the GPU power cables as described in the manual, right?
Yeah lol the GPU is observably receiving power. Lights and fan come on as everything starts up and they stay on. The green safety light is on. I don’t think it’s a power issue.
Most GPUs will have fan spin & lights if only on pcie power (the pcie slot provides 75W without external connection), but then misbehave during display; I know it sounds stupid but make sure the 12V power connector on the top of the card is firmly plugged in, that connector in particular has a reputation for being unreliable.
That doesn’t exclude a power issue. A lot of cards will light up and spin up even without enough power, then stop responding once something actually tries to use its capabilities.
Fair enough then, I’ve just checked the recommended wattage. My PSU is 650W and that’s exactly what the GPU recommends.
