    Arrow F27 turns monitor off on Intel E3800 (N2930) (works only with nomodeset)

    Hello The Best Linux Community on the web!

    For my handy-mandy home NAS/media server project I seem to have too unusual hardware..

    Brief description:
    Right after booting installation media and choosing installer I had problem with screen going completely off (stand-by to be precise) after option to install was activated under Grub2
    I worked that around by using "safe-mode" installer which adds nomodeset to grub.
    This setting gets propagated to the installed system, making it actually boot to GUI. Unfortunately with max of 640x480 resolution and some poor color depth.
    Clearing nomodeset option in Grub2 causes system to boot, but with monitor in standby (I can reach it over SSH)
    Monitor goes into stand-by after about 3 seconds into Linux loading (at least it seems for me like that). It is the moment where Fedora logo would come out after the few initial lines on the console.

    Hardware:
    Aside from attached inxi otput, of course.

    Re: F27 turns monitor off on Intel E3800 (N2930) (works only with nomodeset)

    I was checking on the issue on my own in the mean time. Some more findings:

    1. Similar issue happens on CentOS installer (display goes off at similar moment). I haven't checked logs for details
    2. On my Fedora 27 I got more verbose logs from boot process and pinpointed the exact moment at which screen goes off. Details to follow:
    Line 714 from attached log is the last one seen on the screen:
    "kern :info : [ 3.830357] fb: switching to inteldrmfb from EFI VGA"
    3. Next I added some options regarding i915. See below:
    drm.debug=0 drm.vblankoffdelay=1 i915.semaphores=0 i915.modeset=1 i915.use_mmio_flip=1 i915.powersave=1 i915.enable_ips=1 i915.disable_power_well=1 i915.enable_hangcheck=1 i915.enable_cmd_parser=1 i915.fastboot=0 i915.enable_ppgtt=1 i915.reset=0 i915.lvds_use_ssc=0 i915.enable_psr=0

    I tried with with both i915.enable_psr set as 1 and 0. Either did not work.

    I'd be grateful for any suggestions from the community here.

    For mods/admins: Since this is related to not only Fedora and not installation in particular, can you move it to hardware section? A change in title would greatly appreciated too.

    Re: F27 turns monitor off on Intel E3800 (N2930) (works only with nomodeset)

    Solved!

    Problem seemed to be caused by setting in BIOS of my Jetway NF9W mainboard.
    After disabling "support for DVI-VGA dongle" Linux boot completed fine and FullHD resolution is working in graphics mode.
    Unfortunately I can't access neither BIOS nor Grub screen (since the screen is off during that time. Probably resetting BIOS or using RS-232 will be needed to get around that.

    It was a pleasure to talk with myself..
