hdmi issues

Hello all, first off i am newer to linux and arch and have spent countless hours trying to fix my issue using arch wiki, hyprland wiki and web searches. All with no success. But with that being said i do think its probably something simple I am missing.

My issue is that my hdmi port causes a login loop. I am using hyprland and if my hdmi cable is plugged in when i try to login from my sddm login menu i get a black screen and am reverted back to the sddm login screen. I am unable to login until i unplug the hdmi cable. And if i try to plug in the hdmi cable once logged in successfully it will again boot me back to the sddm login until i unplug it.

I am using nouveau drivers with my asus UX51VZA. it has both an intel and nvidia gpu. here is fast fetch.

                                           

 Kernel: Linux 6.12.27-1-lts
                                            Uptime: 1 hour, 1 min
                                            Packages: 947 (pacman)
                                            Theme: Fusion [Qt], Arc-Dark [GTK2/3]
                                            Host: UX51VZA (1.0)
                                            Icons: breeze-dark [Qt], breeze-dark [GTK2/3/4]
                                            Font: Sans Serif (9pt) [Qt], Noto Sans (10pt) [GTK2/3/4]
                                            Cursor: breeze (24px)
                                            Terminal Font: NotoSansMono-Regular (11pt)
                                            CPU: Intel(R) Core(TM) i7-3612QM (8) @ 3.10 GHz
                                            GPU 1: NVIDIA GeForce GT 650M [Discrete]
                                            GPU 2: Intel 3rd Gen Core processor Graphics Controller @ 1.10 GHz [Integrated]
                                            Memory: 3.19 GiB / 7.64 GiB (42%)
                                            Swap: 0 B / 3.82 GiB (0%)
                                            Disk (/): 15.54 GiB / 115.83 GiB (13%) - ext4

I had started trying to setup proprietary nvidia drivers, all of which never seemed to be loaded when i used nvidia-smi. I also loaded the original hyprland.conf file to see if my settings were causing the issue. this also did not help.

Finally the reason i feel its prob an easy fix is that i installed kde desktop environment, and when i log into kde wayland everything works with no issue.

another thing I am not sure if will help is that im getting these errors related to crtc in my journalctl.

May 07 10:57:55 home kernel: nouveau 0000:01:00.0: [drm] Cannot find any crtc or sizes
May 07 10:57:55 home kernel: nouveau 0000:01:00.0: [drm] Cannot find any crtc or sizes
May 07 10:57:57 home kernel: evdi evdi.0: [drm] Cannot find any crtc or sizes
May 07 10:57:57 home kernel: evdi evdi.1: [drm] Cannot find any crtc or sizes

one difference i noticed between kde and hyprland is that the WAYLAND_DISPLAY=wayland-0 on kde but on hyprland it is WAYLAND_DISPLAY=wayland-1. i tried modifying my hyprand.conf file by adding env = HYPRLAND_WAYLAND=wayland-0. Which again had no affect.

thanks for anyone taking the time to read this and hope it is something simple I am missing.

Re: hdmi issues

Hyprland likely crashes, check your system journal and also https://wiki.archlinux.org/title/Core_d … _core_dump
Then post your hyprland config.

                                            GPU 1: NVIDIA GeForce GT 650M [Discrete]
                                            GPU 2: Intel 3rd Gen Core processor Graphics Controller @ 1.10 GHz [Integrated]

The card order looks reversed, not idea whether this could freak out hyprland, but electron is OTR for stumbling over that.
Add "nvidia_drm.modeset=1" to the https://wiki.archlinux.org/title/Kernel_parameters (regardless of whether you're using the binary driver or this is actually also the module default - the parameter will implciitly block the simpledrm device and hopefully restore the normal card order)

Re: hdmi issues

Hey there thanks so much for your reply!

I had tried adding the nvidia_drm.modset=1 prior with no success. Still not helping with the issue however i do notice initial loading of system dialog to be different. Prior it would take about half way thru loading dialog for font to reduce in size and not look so pixelated whereas now it seems to be good right from the sddm menu.

I tried using journal and coredump but am quite new to this and as such not sure that I am doing things right lol.
i ran

coredumpctl list

and this was present a bunch of times:

 634    0    0 SIGABRT inaccessible /usr/lib/Xorg 

so i than ran

coredumpctl info 634

which has this corresponding line:

Storage: /var/lib/systemd/coredump/core.Xorg.0.39a51768b6d54c4c8f17fb4471a870df.634.1746662642000000.zst (inaccessible)

not sure this helps at all, but thought I would throw it out there. I am new to coredumps and journalsand am currently going over arch wiki and researching trying to learn more and find more that can help and will post back with anymore findings, thanks again.

Re: hdmi issues

have just run

journalctl | grep HDMI

and returned these lines that seem relevant as well:

Re: hdmi issues

Please don't bump. Edit your previous post to mend it if nobody has replied yet.
Please use [code][/code] tags. Edit your post in this regard.

i ran "coredumpctl list" and this was present a bunch of times:
634    0    0 SIGABRT inaccessible /usr/lib/Xorg

You're looking for Hyprland crashes.

The by far most obvious contender is

# See https://wiki.hyprland.org/Configuring/Monitors/

#monitor=,preferred,auto,auto
monitor=HDMI-A-1,1360x768@60,0x0,1
monitor=DVI-I-2,1920x1080@144,800x1080,1
monitor=DVI-I-1,1920x1080@144,2720x1080,1
monitor=eDP-1,1920x1080@60,2520x2160,1

workspace = 1, monitor:HDMI-A-1
workspace = name:1a, monitor:HDMI-A-1
workspace = 2, monitor:DVI-I-2
workspace = name:2a, monitor:DVI-I-2
workspace = 3, monitor:DVI-I-1
workspace = name:3a, monitor:DVI-I-1
workspace = 4, monitor:eDP-1
workspace = name:4a, monitor:eDP-1
#workspace = 10, on-created-empty:[float] firefox--> this to open ap on window open

Comment all of that, try again.

Otherwise:

have just run "journalctl | grep HDMI" and returned these lines that seem relevant as well:

is unlikely to produce meaningful outputs.

Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Re: hdmi issues

hello again and thanks for the pointers. I am assuming by bump you mean posting repeatedly to gain attention. Which was not my intent but i can see the issue and will edit posts if noone has replied in future, thank you and let me know if i misunderstood.

I also went back to edit previous posts with code tags and add 0x0 link for conf file, I hope what I did is correct.

I reran

coredumpctl list | grep Hyprland

the only thing that was repeated was this:

 EDT   850 1000 1000 SIGABRT present      /usr/bin/Hyprland  

I tried commenting out the monitors and workspaces and the issue persists. also again ran

journalctl | grep HDMI

again which did not seem to have any useful output.

lastly here is a link for journalctl -b as requested: http://0x0.st/8J6A.txt

thanks again for your help.

Means that Hyprland aborts. What does the backtrace look like?
Though it'll likely also post an error message, https://wiki.hyprland.org/Crashes-and-Bugs/

Re: hdmi issues

Here is crash report, and as for the DisplayLinkMana stuff i do also have 2 monitors connected via displaylink hub, which are currently not working under stable kernel but work under lts kernel which is what i have been using. Also I have not mention that the hdmi ,displaylink and everything worked fine for quite some time until a few updates ago. Thanks as always!

You did comment out all monitor and workspace lines in yoru config?
Can you start weston/sway/openbox and run "eglinfo -B"?

Re: hdmi issues

hey again sorry for delay. I did comment out monitors as well as try stock hyprland.conf when troubleshooting but reenabled them to continue use when nothing was working. I can rerun anything needed with original conf if helps just let me know.

I have been messing about a lot lately. I have installed other instances of arch like i3 and sway and none have any issues with the hdmi.
Also when installing a fresh arch hyprland, the hdmi works fine after initial successful install and reboot. However as soon as i reboot a second time it reverts back to the issue of not logging in from sddm when hdmi is plugged in and booting me to sddm login if i try to plug in hdmi once i am logged in successfully. This also all happens before i install any packages add or edit any files or do anything.

here is a link to eglinfo -B for my current arch hyprland system: https://0x0.st/8weq.txt
and here is a link to eglinfo -B for a fresh install of arch sway on same laptop but different drive: https://0x0.st/8weo.txt

thanks again for any help.
