Thread: Booting to a black screen; nomodeset didn't fix

  1. #1

    Default Booting to a black screen; nomodeset didn't fix

    I'm trying to dual-boot openSUSE with Windows on my new laptop. My only prior experience with Linux is putting Mint on an old computer and using it like Windows. When I tried to boot, I got a black screen with a single, stationary hyphen thing in the top left corner.

    I've read about people who have NVIDIA graphics, as I do, having to add "nomodeset" to the boot parameters. It makes sense for it to be a graphical issue because the installer gave me the text-based version. I tried nomodeset—I hope I put it in the right place; it was at the end of the Linux EFI line—but I was still getting the same issue. What could this be? I'd really like to use openSUSE; it looks like a lovely distribution!

    If it matters at all, I made a separate partition for /boot.

    Did it ever boot as expected?

    Does it have NVidia graphics only, or also Intel? The two coupled comprise Optimus Graphics, which requires special software and configuration, bumblebee or suse-prime.

    Nomodeset is supposed to be a troubleshooting parameter.

    See if, instead of nomodeset, appending plymouth.enable=0 to the linuxefi line using the E key at the Grub menu helps.

    It has never booted correctly. I tried plymouth.enable=0 and the same thing happened, the black screen without a cursor.

    I do have Intel and NVidia.

    Next I would try plymouth.enable=0 with nouveau.modeset=0 without nomodeset, to see if the Intel GPU can produce some visible output, so that suse-prime and/or bumblebee can be configured.

    After a minute or so of black screen, can you reach a login prompt using Ctrl-Alt-F2 or Ctrl-Alt-F3?

    Well, something's happening! I did plymouth.enable=0 and nouveau.modeset=0. Said it couldn't start the X display manager and prompted me for login and password, which I entered.

    I was going to follow the instructions for configuring Bumblebee or SUSE Prime, but I wasn't able to install the Nvidia driver. I added the Nvidia repository mentioned in the SDB. When I did zypper refresh, it said the Nvidia repository was invalid and all the others couldn't connect because of a "curl error."

    I found here https://unix.stackexchange.com/quest...-opensuse-leap that it could be because it's trying to use IPv6 to connect, but the solution on that page didn't work for me.

    Am I on the right track with things?

    Any help on this? I can't install Nvidia drivers because the system won't connect to any repositories. I'm not sure I'm editing the configuration file correctly as in the webpage I linked.

    Do you have a network connection? How WiFi or cable?

    Depending on the hardware you may need a driver for WiFi. But wired should work in any case.

    I do; I'm using wi-fi. During installation the connection worked, and it seemed to be able to set up the repositories just fine. The link I posted said Zypper might be trying to use IPv6, and indeed I only have IPv4 so I don't know if that's the issue.

    Have you tried appending ipv6.disable=1 to kernel cmdline? I don't get curl errors using it. I have in /etc/sysctl.conf uncommented lines only net.ipv6.conf.all.disable_ipv6 = 1.

    Accidentally deleted my post. It's getting somewhere! Disabling IPv6 didn't help my connection, so I just plugged in an ethernet cable for now. I went and installed Bumblebee.

    This time I didn't need to edit the boot options, and I got the Leap logo before the command line came back. Now how do I start the graphical interface? I ran startx but it said xinit failed and I should use a display manager.
