Installed Intel Arc 380 GPU, but my monitor has now the wrong resolution

Today I finally received my shiny Arc 380, but unfortunately my monitor (1920x1080 max resolution) is no longer detected properly. In fact I end up with a resolution of 1280x720 which makes everything stretched.

Before the Arc 380, connecting the monitor to the integrated GPU provided all the resolution options correctly.

I tried adding the resolution via xrandr:

Code: [Select]
$ xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
$ xrandr --addmode HDMI-1 1920x1080_60.00

But if I select it, this is the unlucky output:

Code: [Select]
$ xrandr --output HDMI-1 --mode 1920x1080_60.00
xrandr: Configure crtc 0 failed

These are all useful details:

I am using Plasma 5 with Wayland

Code: [Select]
$ uname -r
6.7.7-artix1-1

$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 720, maximum 16384 x 16384
HDMI-1 connected primary 1280x720+0+0 (normal left inverted right x axis y axis) 278mm x 124mm
   1280x720 60.00* 59.94  
DP-1 disconnected (normal left inverted right x axis y axis)
HDMI-2 disconnected (normal left inverted right x axis y axis)

Thank you for your time and reply :)

unfortunately in the linked thread (if I haven't misunderstood, as I may have missed some details as English is not my native language) it mainly refers to the kernel version which should be > 5.19.0 and the most updated version of mesa in October 2023. I'm on 6.7.7 and the version of mesa that I have installed is 1:24.0.2-1; in this case unfortunately I don't have any steps to take by following these directions. :(

Update:
I updated the system and now the device ID changed (is now HDMI-A-1) and it also show some other supported resolutions (but they are not correct with my monitor which still is a 1920x1080. In fact, unfortunately, I keep seeing the screen smeared, which is not really good for me and my eyes. Here is the xrandr output:

Code: [Select]

Update:

I have noted that when I try to select the manually added resolution (which does not work either) now the output is changed:

Code: [Select]
$ xrandr --output HDMI-A-1 --mode 1920x1080_60.00
X Error of failed request:  BadValue (integer parameter out of range for operation)

When I get the error, this time, the display does not try to go into this resolution.
Still having same wrong resolution :(

Update:
I tried booting with Zen kernel and also with some kernel mode settings (KMS) parameters;
I first identified the connected device with:

Code: [Select]
for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done

in my case it was HDMI-A-1

then set the default mode setting in grub:
/etc/default/grub
Code: [Select]
GRUB_CMDLINE_LINUX_DEFAULT="quiet i915 video=HDMI-A-1:1920x1080@60"

and update grub:
Code: [Select]
doas grub-mkconfig -o /boot/grub/grub.cfg

It doesn't change.

Also I tried to connect a different monitor to the Arc 380: it flawlessly works with the correct resolution.

So:
- iGPU with my monitor A (the one which I should solve): perfect native resolutions
- iGPU with my monitor B (testing monitor): perfect native resolutions
- GPU (A380) with my monitor A: only one resolution option and it is wrong
- GPU (A380) with my monitor B: perfect native resolutions

Also:
- if monitor A is connected to GPU (A380), on Bios/Boot screen it has the correct resolution (1920x1080), in Grub menu it has correct resolution, then it gets the wrong resolution.

I also tried with X11 instead of Wayland; nothing changed too. Hope this can be helpful for someone else and hope someone can help me out with this issue.

You've mentioned xrandr quite a bit. I'd missed the 'Wayland' bit.
Does xrandr support wayland now ? If not xrandr was never going to help.

I don't know the answer to your issue but I'd suggest one road you should be exploring is edid's

You are right. I started doing it wrong, using xrandr on Wayland, then I found out that xrandr works only in X11. Unfortunately xrandr new mode did not work on X11 either to set the correct resolution.

Unfortunately I think this is the last and only way I can try, since I tried every other way I could find out on the web.

I already took the edid way.
Connected the monitor A to the iGPU, then read the edid and I had this:

Code: [Select]
Checksum Correct

        Option "DPMS" "true"
        Horizsync 30-81
        VertRefresh 56-76
        # Maximum pixel clock is 170MHz
        #Not giving standard mode: 1280x720, 60Hz

        #Extension block found. Parsing...

        Option "PreferredMode" "Mode 2"
EndSection

Don't know if it show the correct resolution tho (1920x1080).

So, I followed the guide to force mode and edid; also loaded the resulting
Code: [Select]
/sys/module/drm/parameters/edid
inside mkinitcpio.conf via
Code: [Select]
BINARIES=(/sys/module/drm/parameters/edid)
, recompiled everything with
Code: [Select]
mkinitpio -p


No result.

I also copied the edid.bin into 1920x1080.bin as the guide said, but if I put KMS
Code: [Select]
drm.edid_firmware=edid/1920x1080.bin drm.edid_firmware=HDMI-A-3:edid/1920x1080.bin
the display goes black after the booting sequence.

What a stress; I could watch the YouTube video, but I think that the problem is this monitor with this GPU. How to solve this?

I found the problem, maybe.

I connected the monitor A (1920x1080) to the iGPU and I got the correct display resolution. Then I did
Code: [Select]
# get-edid | parse-edid
and what I got is that:

It is exactly the same edid I get when I connect the monitor A to the GPU (A380); this is really confusing me; how can it be that the same edid makes different resolutions between GPUs?

Well the edid data comes from the monitor so you'd reasonably expect it to be the same.
The difference will be in how the GPU driver handles the edid information.
From what little I know about ARC I believe it uses a different driver than intel's integrated on cpu die gpu's?

Many moons ago a had a monitor which was doing the same as yours is (or isn't to be more exact)

This was with an nvidia GPU. The solution was to get the edid in binary format. Edit it with some program I'd found and advice and instructions from who know where but if they still exist I imagine it's only on the wayback machine ?
Then you had to tell the nvidia driver to use the custom edid file. Fairly sure this went in xorg.conf but something's telling me it might have been a kernel command line option which needed to be in the initramfs as well. Or maybe I had to do both?
Plenty of warnings were given on the pages I was reading. "This can damage or destroy your monitor if done wrong etc etc." But as I was close to putting a spanner through it I tried it anyway, and it did work eventually after some messing about.

Sorry that is so vague but that's the best I can recall. Whether a custom edid is even an option with the intel ARC driver I have no idea ?

I think you should consider finding the intel ARC support and / bug sites and seeking help there as from what I've heard they have a lot of resource dedicated to improving ARC on LInux as well as Windows.

It could even be a simple as an option to set in the kernel command line or elsewhere?

Edit: And sorry I missed that fact you'd posted twice since my last post and have already been trying with the edid.

I thank you very much for your message,
I have tried, but I still haven't solved it. The edid file I can retrieve from the monitor is wrong and I thaught both Arc and Intel Iris Pro II (iGPU) used both same Intel driver.

I have contacted the company that manufactures these monitors to speak to someone about the wrong edid of their monitor, unfortunately they never answered (MASPRO DENKOH Corp L1 of Kefeya), neither a "we don't know, sorry".

For the health of my eyes I have temporarily removed the GPU and am using only the iGPU and that is a pity, since I can't use both my monitors. I don't think I am capable of creating an edid file and I am afraid that if I get it wrong I might irreparably break something, which is a consequence I cannot afford.

If anyone has any ideas or can help me or provide any advice I renew my request for help. 🙏

Updates:

I stopped trying with Wayland since the only solution whit it (which is too risky and hard to me) is to build a new edid file for this monitor.

Then I went back to X11.

Since I can select only the wrong resolution 1280x720, I added the correct one with xrandr (both with the cvt -r option), and:

Code: [Select]
$ cvt 1920 860 59
# 1920x860 58.98 Hz (CVT) hsync: 52.61 kHz; pclk: 133.00 MHz
Modeline "1920x860_59.00"  133.00  1920 2024 2224 2528  860 863 873 892 -hsync +vsync
$ xrandr --newmode "1920x860_59.00"  133.00  1920 2024 2224 2528  860 863 873 892 -hsync +vsync
$ xrandr --addmode HDMI-3 1920x860_59.00
$ xrandr --output HDMI-3 --mode 1920x860_59.00
xrandr: Configure crtc 0 failed

So the correct resolution fails.

But if I try a more standard resolution like 1920x1080, something strange happens:
Code: [Select]
$ cvt -r 1920 1080
# 1920x1080 59.93 Hz (CVT 2.07M9-R) hsync: 66.59 kHz; pclk: 138.50 MHz
Modeline "1920x1080R"  138.50  1920 1968 2000 2080  1080 1083 1088 1111 +hsync -vsync
$ xrandr --newmode "1920x1080R"  138.50  1920 1968 2000 2080  1080 1083 1088 1111 +hsync -vsync
$ xrandr --addmode HDMI-3 1920x1080R
$ xrandr --output HDMI-3 --mode 1920x1080R

It works. I get this new wrong resolution which is a bit near the original resolution of the screen (but still the whole screen seems like smeared/spread [hope this words let's you understand since this is not my native language]).

Tried with 1920x900 or 1920x800 but it doesn't work.

I am actually under i915, if I wrote all this code is for someone who's having the same issues, thinking this could be handy.
If someone has some solution under X11, please let me know. 🥲🙏

ps: graphic card 3d acceleration works tho

Interesting Updates:

I tested my monitor with Windows 10 to see if I could get more interesting information, and indeed there were some advances:

Using EnTech Monitor Asset Manager, I got a complete readout of the edid file, and this is where the interesting news popped up: the edid.bin file of my monitor reads:
Code: [Select]
Native/preferred timing... 1920x860p at 60Hz 
    Modeline............... "1920x860" 110,680 1920 1968 2000 2106 860 863 868 876 +hsync +vsync

Standard timings supported
    1280 x 720p at 60Hz - VESA STD
.

So I tried again using the edid.bin file and:

- I put the edid file in /usr/lib/firmware/edid/.
- I set
Code: [Select]
MODULES=(i915)
and
Code: [Select]
FILES="/usr/lib/firmware/edid/edid.bin"
in /etc/mkinitcpio.conf. Then ran
Code: [Select]
mkinitcpio -P

- I put the KMS
Code: [Select]
drm.edid_firmware=HDMI-1:edid/edid.bin drm.edid_firmware=HDMI-A-1:edid/edid.bin
in the GRUB_CMDLINE_LINUX_DEFAULT of /etc/default/grub. Then clearly run
Code: [Select]
grub-mkconfig -o /boot/grub/grub.cfg
(I set the custom edid two times since HDMI-1 is the way X11 identifies my monitor and HDMI-A-1 since it is the way Wayland identifies it).

Now if I check with dmesg there is no error and the edid file is loaded correctly without any problems, as is the i915 module.
The Xorg log is also completely clean and there are no problems. The i915 driver is loaded correctly and the only missing feature (due to my motherboard) is the resizeable BAR, which is not important to solve this problem.

Despite this, on both Wayland and X11 the only resolution that can be set is 1280x720 (always stretched). Using X11 and xrandr I can add the modeline 1920x1080 and use it (maybe because it is Standard) but still everything is stretched since it doesn't respect the screen ratio.

So I tried configuring inside /etc/X11/xorg.conf.d/20-intel.conf file:

Code: [Select]
Section "Device"
    Identifier "IntelGraphics"
    Driver "modesetting"
#    Driver "intel"
    Option "AccelMethod" "sna"
    Option "DRI" "iris"
#	Option "DRI" "2"
    Option "CustomEDID" "HDMI-1:/usr/lib/firmware/edid/edid.bin"
    Option "CustomEDID" "HDMI-A-1:/usr/lib/firmware/edid/edid.bin"
    Option "IgnoreEDID" "false"
    Option "UseEDID" "true"
EndSection
.

But despite all this, on both X11 and Wayland the only resolution that can be set is 1280x720.

I tried to user xrandr on X11 to therefore add by hand the modeline specified in the edid file ("1920x860" 110,680 1920 1968 2000 2106 860 863 868 876 +hsync +vsync). Doesn't work.

If I use the Arc 830 it seems that I can only set the Vesa Standard resolution (1280x720) and not the preferred one indicated in the edid file (1920x860). This is so annoying.

I hope someone can help me or can give me further guidance and that this information can be a guide for those in the same situation as me. I would like to do a bug report in regard to this issue, but doesn't know where/who.

ps: if some info or reports are needed please let me know.
