Different versions of display EDID

KorialStrasZ · 01-25-2019, 02:22 AM

My problem is i can't get laptop monitor working with kernel 4.19.17, but still working with kernel 4.4.14.
When i see Xorg.log i find that there is different EDID versions, i the strange is that with newer kernel EDID version is lower.
Xorg.log with kernel version 4.19.17:

When i boot with kernel 4.19.17 i get message:
18.956416 nouveau 0000:01:00.0: DRM: DDC responded, but no edid for eDP-1
This is before startx, i try with different xorg.conf parameters but not solved the problem. I also try with different kernel parameters in Lilo, but not solved the problem.

My question is where is this EDID file and can i copy the file with new version to older one?

The EDID you show is from different connectors, so would be expected to be different as coming from different displays. The first is from an external (DisplayPort DP-3) connection, while the latter is from the laptop's display (eDP-1)

The NOUVEAU(0) you see reported in Xorg.0.log is the old technology X/DDX driver, which is not the same thing as the nouveau driver in the kernel. If you switch to the new technology X/DDX driver you may find the problem you are experiencing to disappear. Simplest way to make the switch is to remove the old tech driver, then restart X or reboot. Upstream's name for it is xf86-video-nouveau, but your distribution may have another name for it, possibly xserver-xorg-video-nouveau or xorg-x11-drv-nouveau. The new tech DDX driver name is modesetting. It is not provided by a separate package. Instead it is included with the server package since 1.17.0.

With kernels new as 4.4 you should have an X server (1.17.0 or newer) that has no need for xorg.conf in order for FOSS DDX drivers to function correctly. It is opposite if using non-FOSS X drivers, such as those from NVidia. If switching from a proprietary driver to a FOSS DDX driver you must follow the proprietary driver's uninstallation instructions exactly, lest you encounter problems such as that you are reporting here. With FOSS DDS, xorg.conf* is optional and unusually needed.

KorialStrasZ · 01-28-2019, 05:05 AM

Ok, i remove nouveau driver from xorg.conf and set modesetting.
I have installed xf86-video-nouveau-1.0.15-x86_64-3 and xorg-server-1.20.3-x86_64-1
But nothing changed with modesetting driver, X start but no EDID for eDP-1 /my laptop screen/ and i can't activate it from dysplay and monitor settings or terminal. Everithing is the same as i use nouveau driver.
I try to blacklist nouveau, but after that with "modesetting" driver can't start X.
Shoud i recompile kernel without nouveau support?

mrmazda · 01-28-2019, 08:22 AM

Please share output from

Code:

inxi -GxxSM

and entire Xorg.0.log from using the modesetting driver.

What does

Code:

xrandr --listproviders

report?

Does it help to boot with video=eDP-1:e appended to kernel cmdline?

video=eDP-1:e to kernel parameters enable the eDP-1 and its says "connected" in logs, but i can't activate and always stays blank, and in System settings -> hardware -> display and monitor -> size and orientation i see section "Size" in white but inside is only "disabled" choice and no resolution. I try to load the EDID of laptop screen but somehow linux load this edit to DP-3 /my external monitor/

But this way is not working, and again in logs is no EDID for eDP-1

I expected more lines from output, like so:

I don't know if my info above can help you. Maybe it is time to report a regression bug to Slackware. Can you try a live distro with 4.19 or 4.20 kernel to see if it has the same problem? Maybe there is an upstream bug already known, either kernel or Xorg, and maybe fixed after 4.19.17.

I mean that EDID is going to DP-3, and only my external monitor is working again even with EDID from my notebook screen with 1920x1080, and my native resolution on my external monitor is 1600x1200.
And xrandr --listproviders gives me only this, no DP no VGA, nothing.

No, now i'm with linux-4.19.18
I will try with live CD soon.

EDID comes from a display. The EDID that Xorg.0.log is showing is coming from the only connected display that the server is finding. You see no EDID for the laptop display because the server thinks it is not connected:

Code:

[   171.452] (II) modeset(0): Output LVDS-1 disconnected
[   171.452] (II) modeset(0): Output DP-1 disconnected
[   171.452] (II) modeset(0): Output DP-2 disconnected
[   171.452] (II) modeset(0): Output eDP-1 disconnected
[   171.452] (II) modeset(0): Output DP-3 connected
[   171.452] (II) modeset(0): Output VGA-1 disconnected

Missing EDID is a symptom, not the disease. Why the internal display is not found needs to be corrected before its EDID will be reported. Maybe the newer kernel is responding differently to a BIOS setting than the old kernel did, and a BIOS change can be made to correct the mal-reported connection.

Something else to try would be a different cable type for the external display. Which connector on the display is being used for video input?

No i mean when i boot with kernel parameters to laptop screen EDID like this in Xorg.low which i upload here.

Quote:

drm.edid_firmware=edid/8570w.bin

So i start kernel with this EDID, but system is setting this EDID to only found connected monitor DP-3 /external/.
I hope when i give the right EDID system to enable the laptop screen, but not.

My external monitor have only DVI. Monitor is HP LP2065. I connect monitor through docking station but that is not a problem because with older kernel everything works just fine. Now i will try with live linux and will report soon.

KorialStrasZ · 01-29-2019, 12:40 AM

Ok, i run manjaro-kde-16.08-x86_64.iso
Its coming with kernel 4.4.19-1-MANJARO
Everything works just fine!
Here is Xorg.0.log

KorialStrasZ · 01-29-2019, 12:55 AM

BTW, when i remove my laptop from docking station and try to boot, the screen freeze on this line, but Caps lock and num lock is still functional.

Quote:

kernel: [ 7.882443] fb: switching to nouveaufb from VESA VGA

And if laptop is connected to docking station and external monitor, on this line laptop screen became blank and start external monitor, and laptop screen always stays blank. Before this line laptop screen is active and external monitor is blank.

KorialStrasZ · 01-29-2019, 01:38 AM

Ooops, this kernel is not good kernel 4.4.19-1-MANJARO
I start with another Live distro.
