I tried from the live USB Ubuntu 20.04.2.0 LTS and Lubuntu 20.04.2 LTS (both desktop, downloaded from their official sites). Ubuntu live USB: I can't see anything at all, only stripes. Lubuntu works fine live with safe graphics mode on but after installing the screen looks with stripes too. Is there a way to add the driver to the live Ubuntu or Lubuntu USB stick from a windows machine? I'm a total newbie so any kind of help will be appreciated.

AMD/ATI Super Sumo Radeon HD 6410D. AMD A4-3300 Processor.

    Hey Victoria Samotracia! "...all I can see is stripes" Can you please add a photo of the stripes in the question such that we can understand the problem more clearly? BTW, I suggest you to go through the tour page. Jun 12, 2021 at 16:26

  • If you can take a photo with your smartphone and share the photo, it might be helpful. Jun 12, 2021 at 16:45

    If the live disk works but it fails after install, then an incompatible driver is being installed that isn't being used by the live disk. Sometimes you can boot the installed system with nomodeset and try ubuntu-drivers autoinstall

actually yes, but that seems not to be that straight forward. As you call yourself a newbie I recommend not doing it. If Lubuntu works fine this might not to be a driver issue perhaps since both should use the same base/kernel. The AMD driver comes with the kernel itself. Maybe you might install Lubuntu update(!) and install the DE (desktop env) you prefer such as GNOME38.

  • Thanks for your answer. Lubuntu 20 Live USB worked fine but after install I had the same problem (can't see the screen, just blue stripes). Jun 12, 2021 at 16:45
  • That sounds odd. Which driver are you using? The Mesa driver?

The issue is that the default graphics driver is not working correctly with your video card. The safe graphics mode disables the incompatible part of the video driver, but leaves you with no video acceleration.

As a temporary fix, you can enable safe graphics mode for the installed ubuntu by selecting an entry in the grub menu and editing it (press e) to add nomodeset to the linux line. See What is safe graphics mode?
Note that this only changes the in memory version of the grub menu, this is temporary only. If this doesn't work, it is possible to completely disable graphics and force text mode via a similar edit.

Once you have booted into a usable video mode (graphics or text), you then need to install a video driver appropriate for your video card. The command sudo ubuntu-drivers install should do the hard work of selecting the correct driver and installing it. (Note that this will try to download drivers from internet, so your network must be working for this to help.)

After successfully installing the driver, you will need to reboot. If everything works, you shouldn't need to use nomodeset again.

  • Thank you. sudo ubuntu-drivers install gives me "no drivers found for installation" I also tried sudo ubuntu-drivers autoinstall followed by sudo apt upgrade It downloaded something but after boot I had the same problem with the screen. Jun 15, 2021 at 1:50
