I have a new PC with intel i7 10700 CPU and an ASUS B560M Pro4 MOBO. I've installed Ubuntu 20.04 using Safe Graphics mode but whenever I boot, it goes to a black screen (monitor says no signal). I've tried reinstalling, downgrading my intel microcode version, and adding the dis_ucode_ldr flag on boot, but nothing has helped. I'm at a loss as to what to do, and am unable to use the new PC at all.

EDIT: Adding nomodeset appears to boot, but only in low resolution, which I can't change. I looked at Additional Drivers, and it says "No additional drivers available." How do I increase the resolution? Thanks!

  • Have you tried adding 'nomodeset' to the boot parameters? – KGIII Mar 23 '21 at 00:43
  • I just tried and it appears to boot. What does that mean? Is that something I should always keep on or are there drawbacks? I'm only able to do 1024x768 graphics... – Nezo Mar 23 '21 at 00:47
  • Now that you're into the OS in a graphics mode, I'd update everything and check to see if there are graphics card drivers available. The nomodeset bit is explained here. In one form or another, your question is likely a duplicate. If you can't graphically get a resolution that you like, you can take a look at xrandr. – KGIII Mar 23 '21 at 00:56
  • I tried sudo apt-get upgrade. I also tried looking for intel graphics drivers, and I've either found that they're already included, or that I can install them with an app called Linux Graphics Update Tool for Linux. This tool has since been removed (https://01.org/linuxgraphics/downloads/update-tool), so I think that many of the answers that have existed for this question are no longer applicable (and thus not a duplicate). How else might I update the graphics drivers? Or confirm if they're even missing? – Nezo Mar 23 '21 at 01:38
  • You can try sudo ubuntu-drivers autoinstall and if this doesn't get you the resolution you want (and nobody else chimes in with an answer) then you can keep using nomodeset and experiment with xrandr. – KGIII Mar 23 '21 at 01:46
  • ubuntu-drivers autoinstall didn't find any drivers (only Nvdia and AMD). I tried using xrandr, but to no avail ("xrandr: Configure crtc 0 failed"). Is this an issue I might be able to fix by using a different Linux OS? Should I just give up and by a dedicated GPU? – Nezo Mar 23 '21 at 02:17
  • I would suggest asking a new question about xrandr and your current predicament. – KGIII Mar 23 '21 at 11:50
