• New GPU + 4K Monitor, Got Xorg Error: no screens found (EE)


    Hi,

    TL:DR:
    I upgraded the monitor from 1080p to 4k UHD, changed GPU from a PCI-e AMD to the internal Intel HD 4400, and could not start X.

    Antergos has been running fine with an AMD PCI-e GPU via HDMI to a 1080p monitor.

    Things I did differently that caused the problem:

    1. changing to a new monitor @ 2160P
    2. changing GPU from the PCI-e AMD (which doesn’t support 4K) to the internal Intel HD 4400 via DisplayPort, which does support [email protected]

    Problem:
    Cannot log in to Xfce DE.
    Can see BIOS / Grub2 / systemd msgs, but hangs at “Reached Target Graphical Interface”.

    Troubleshootings I tried:

    1. I thought maybe display manager was the issue, so I tried sddm/gdm/lightdm, none worked;

    2. I removed all display managers, and tried simply startxfce4, and got this error from Xorg:
      Fatal server error: no screens found (EE)

    3. I thought maybe Intel drivers wasn’t installed (as I was using AMD before), then I found out xf86-video-intel, mesa, xf86-video-fbdev were all installed, I also tried removing xf86-video-intel suggested here, but it didn’t work;

    4. It didn’t work in neither linux (4.14.x) nor linux-lts (4.9.x) kernel, and I also tried modesetting with i915 as suggested here, reinstalled kernels, but it did not work;

    5. In the BIOS, I tried setting GPU preference to either “AUTO” or “using Internal” (with or without multiple GPUs), did not work;

    6. If I use lspci I can see the Intel GPU when BIOS is set to “using internal gpu”, or I can see both the Intel and AMD GPUs if the BIOS is set to “auto”;

    7. To make sure the physical connection actually works, still using Intel GPU and DisplayPort, I boot up Antergos and Solus Live CDs, and I can use 4K in the LiveCD session; so the connection and screen do work; I can also connect a Macbook Pro running Antergos at [email protected] via mDP to DP to the screen, and the screen runs [email protected] smoothly.

    8. I tried running “Xorg :0 -configure” and I got a segmentation fault;

    9. I tried manually setting an Xorg config file at /etc/X11/xorg.conf.d/10-monitor.conf as suggested here, it did not work, so I removed that file.

    Could someone please let me know how I could fix it? Thank you very much!

  • Thank you, problem solved!

    Initially when I tried:
    ls /etc/X11/xorg.conf.d

    There’s nothing interesting, just 3 files:
    00-keyboard.conf
    50-synaptics.conf
    99-killX.conf

    I added a “20-intel.conf” like my other machines running Intel graphics, but still I couldn’t login.

    Then I remember my amd config file was somehow stored inside:
    /usr/share/X11/xorg.conf.d

    I removed the 20-redeon.conf there and rebooted, then problem solved.

    Thank you very much for the help and it’s always good to learn something new every day!
