Video crash: i915 Fault errors on pipe B

With my monitor (HDMI1) off, if i run: 

xrandr --output eDP1 --off --output HDMI1 --auto

i915 crashes with the error i915 0000:00:02.0: [drm] *ERROR* Fault errors on pipe B, I can access the machine over ssh but there's no video besides random lines with colors, i also can not shutdown the machine (maybe related to this error filling the journalctl logs?) or go to another tty, the screen is frozen.

This is only happening if I turn off eDP1 (my laptop screen) and use --auto on HDMI1, running
xrandr --output eDP1 --off --output HDMI1 --mode 1360x768
everything works just fine.

Edit: is also happening by running:

xrandr --output HDMI1 --off
xrandr --output HDMI1 --mode 1360x768 --output eDP1 --off

I tried to drowngrade linux-lts, linux-firmware, intel-media-driver and intel-ucode but that did not solve the issue. Since I don't use often this setup (eDP1 off, HDMI1 on) I don't know when or what package introduced this behavior. 

pacman -Qi intel-media-driver | grep Version

Version         : 23.3.0-1
journalctl -r -p 3

Re: Video crash: i915 Fault errors on pipe B

Since I don't use often this setup (eDP1 off, HDMI1 on) I don't know when or what package introduced this behavior.

Certainly not the intel-media-driver.

Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General
Have you tried to re-enable the eDP from ssh? Does that restore the graphics?
Can you use the HDMI while the eDP is still active?

In doubt remove xf86-video-intel ("HDMI-A-1 mapped: HDMI1" looks like you installed that)

Yes I did and no, once the video is gone, running xrandr... only causes more weird behaviors, like my laptop screen flickering. (and auto completing xrandr crashes the command, other commands are also "unresponsive")

seth wrote:

Yes? On startup the screens are mirrored (that's the default i think), and I have a script that runs:

    xrandr --dpi "${dpi:-96}" --output eDP1 --auto \
        --output HDMI1 --primary --right-of eDP1 --auto

The script works.. the problem is when HDMI1 is --off and I run  xrandr --output eDP1 --output HDMI1 --auto # or --mode WxH

I also have set export LIBVA_DRIVER_NAME=iHD

Yes I have.

Before removing xf86-video-intel this was the config I was using (should have added this on the beginning):

# /etc/X11/xorg.conf.d/20-video.conf
Section "Device"
        Identifier "Intel Graphics"
        Driver "intel"
        Option "AccelMethod" "sna" # default
        # Option "AccelMethod" "uxa" # fallback
        # Option "TearFree" "true"
        Option "DRI" "3" # force DRI3
EndSection

Before
Xorg.0.log.old with xf86-video-intel

After removing xf86-video-intel the same problem happened the second time i run the problematic xrandr command.
Xorg.0.log.old without xf86-video-intel

With xf86-video-intel
No xf86-video-intel

Re: Video crash: i915 Fault errors on pipe B

You mean the problem is exclusive to making multiple randr changes in one call?
You can perfectly fine de/activate the outputs individually, just trying to configure them at the same time fails?
(xrandr has long struggled with this and the recommendation would be to not do that and sequence the changes)

Re: Video crash: i915 Fault errors on pipe B

Did updating to 6.1.45 fix this?  See: https://github.com/openwrt/openwrt/pull … 1675723788

Maybe that's the issue (making the changes in one call), but I didn't test making one at a time though.

I am starting to think that this is a hardware issue, because I just tested all the commands again and it just worked (without xf86-video-intel). I will install it again and see if that changes.

Edit: i just switched to xf86-video-intel and run the commands again

xrandr --output HDMI1 --off
xrandr --output HDMI1 --auto
xrandr --output eDP1 --off ; xrandr --output HDMI1 --auto
xrandr --output HDMI1 --off --output eDP1 --auto
xrandr --output eDP1 --off --output HDMI1 --auto

And no problems, I have no idea what happened. neutral
Even my script that initially triggered the problem is working now when i select only HDMI1.

I don't know, but i also switched from 6.1.44-1-lts to 6.4.10-arch1-1
