    Display issues on Fedora 27 Xorg

    I need to be able to see the same screen in VNC as on the screen and as far as I know Wayland does not support this.

    So I went to Xorg. Now I am having an issue with the display only being 640x480

    When I run xrandr I get as follows.

    xrandr: Failed to get size of gamma for output default
    Screen 0: minimum 640 x 480, current 640 x 480, maximum 640 x 480
    default connected 640x480+0+0 0mm x 0mm
    640x480 73.00*

    [root@methanemaker ~]# inxi -G

    Is there an easy fix for this?

    Re: Display issues on Fedora 27 Xorg

    I saw elsewhere that the i915 does not like the nomodeset flag so I copied the line in /etc/default/grub commented out the original and removed nomodeset from the active line. Then ran
    "grub2-mkconfig -o /boot/grub2/grub.cfg"
    then rebooted but no luck

    Re: Display issues on Fedora 27 Xorg

    To sum up.
    It was the nomodeset flag I just was not updating grub correctly.
    my /etc/default/grub looks as follows

    GRUB_TIMEOUT=5
    GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
    GRUB_DEFAULT=saved
    GRUB_DISABLE_SUBMENU=true
    GRUB_TERMINAL_OUTPUT="console"
    #GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora00/root rd.md.uuid=c449cef5:b0e299dd:028e55af:fa683980 rd.md.uuid=9e9d3e25:0a50591a:e2541589:55d13aab rd.lvm.lv=fedora00/swap nomodeset rhgb quiet"
    GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora00/root rd.md.uuid=c449cef5:b0e299dd:028e55af:fa683980 rd.md.uuid=9e9d3e25:0a50591a:e2541589:55d13aab rd.lvm.lv=fedora00/swap rhgb quiet"
    GRUB_DISABLE_RECOVERY="true"

    If you use EFI you need to use

    grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

    to update grub
