【Solved】Display Problems on Repaired HP-Envy 15t-ep000

[nmssis]

Sorry for the delayed response.

Everyone has a life outside of this forum. I've been on threads where there is literally weeks before a response is posted. Plus many people are in different time zones across the globe.

The log shows a problem with the WiFi adapter. I would not think that would be related to the screen, but I'll do some checking to see what I can find.

All the UFW BLOCKS are the firewall protecting your system. I checked the command on my system first to make sure I typed it correctly and all 200 lines on my computer were UFW BLOCKS.

I guess the WIFI errors were unexpected . But so far, do you believe it is a software or hardware issue? Or do you need more information?

Because we are able to see a difference in the different kernels (from no glitching with the 5.0 to some with 5.4 and a permanent glitch with anything higher) and that other person had the same issue, I'm thinking it is somehow related to the software's interaction with the hardware.

You may be right, considering that we saw earlier that there were various issues in regards to the graphics drive. Again, thank you for helping me so far!

I found another one: Live USB only displays on half the screen - installation fails. It's also an HP Envy with a 10th gen Intel processor and a 1650 Ti GPU and the screenshot will be familiar to anyone reading this thread. Starting to see a trend here. All the items mentioned in the comments as possibilities were already ones I've considered and we've tried.

I found that when I went looking for split screen issues. However, looking closely at the first video you posted, it appear the second squished image is atop the full screen image. There are actually two images being projected on the screen at the same time. When you used the 5.8 kernel there was only the one squished image and the lower part appears to be backlight bleeding of a sorts. That means the 5.8 kernel did not have the problem of two images being projected simultaneously.

I read through the Maintenance and Service Guide - HP ENVY and other documentation and I have not been able to figure out what could be causing what is happening.

The only possible clue I could find was a troubleshooting thread where someone was only seeing half their screen and the response was, "This just happened to me after a new motherboard was put in by a Dell tech. Turns out that the video thought it was attached to an external TV, so was restricting my choices of resolution modes." I did not see anything in the xrandr --verbose you posted which indicated a possible different resolution, but that was for the 5.4 kernel which is mostly giving a full screen. I do not know if somehow screen resolution might be a way to fix the 5.8 kernel. I would have thought that was something the other two people with the same laptop and the same issue might have tried it already, but I did not see it mentioned.

So if you want to give it a try, install the 5.8 kernel and boot into it and then run xrandr --verbose and we'll see if the output is different in any way. See if there looks like any different options in the Displays app.

Actually, if you've not tried different Display settings the 5.4 kernel, that is something to try. See if there are different refresh rates or resolutions to try.

If you select Normal or HiDPi on the User Interface Scale drop-down, then you can change Fractional Scaling. Maybe something there will help or give us some clues as to what might help.

Let us know what you find even if it looks like none of it makes a difference. One misses 100% of the shots one doesn't take, so shoot.

There are actually two images being projected on the screen at the same time.

That's a symptom of problems with 4k video. Only half of the screen is painted at a time, and when two separate images appear, it usually means that the display hasn't picked up on the fact that it's getting a 4k/2160p composite image, or the video card hasn't told the display. Though on reading the first few posts, you're dealing with only 1080p.

I haven't read the entire thread but thought I'd mention that in case it provides a clue. It might also be worth trying both a mainline kernel and 5.10-oem.

Both images are full images, but one is full screen size and one is full image but only in the upper half of the screen (so entire image squished into just the upper half). Same thing is happening regardless of using Intel or Nvidia (it's a dual-graphics laptop).

I will look at the laptop's specs again tomorrow when I am more awake to see if maybe they switched screens when it was repaired. I think more than one option screen was available for the laptop.

It might also be worth trying both a mainline kernel and 5.10-oem.

Summary so far:
kernel 5.0 - full size image
kernel 5.4 - full size image with second image appearing randomly. Second image is full image but squished in the upper half of the screen.
kernel 5.8 - full image squished into upper half with apparent bleed lines in lower half
kernel 5.10-oem - same as 5.8 kernel

Edited to add:
kernel 5.6-oem is same as 5.8 kernel (full image squished in upper half)
BIOS/UEFI - full size image
Windows 10 - full size image

Good call. Something is seriously screwy with this machine.

[SMG]

Good call. Something is seriously screwy with this machine.

Except it's not just this machine.

There are at least two others of this HP model out there doing the same thing when using Linux (Arch, Pop OS, Majaro, Ubuntu, Centos). Those two are just doing the squished in the upper half of the screen part. That's what makes me think those ones might have the higher resolution screen, because the one in this thread was fine with Pop OS until the repair happened.

It's an OLED screen if that might give clues to what is happening.

[Moonstone Man]

It's an OLED screen if that might give clues to what is happening.

No, it shouldn't matter. The only trouble with OLED is that OP might need to be told that OLEDs will burn in, even though most people think those days are long gone. Screen blanking and low brightness will help to prevent it.

Actually, if you've not tried different Display settings the 5.4 kernel, that is something to try. See if there are different refresh rates or resolutions to try.

I just tried the 1680x1050 display and it does still glitch just like the 1920x1080.

If you select Normal or HiDPi on the User Interface Scale drop-down, then you can change Fractional Scaling. Maybe something there will help or give us some clues as to what might help.

I also tried the fractional scaling (1920x1080) for the 5.4 kernel and the screen froze and the mouse wouldn't move. So I restarted three times . The first two times the keyboard output didn't register when I tried to login. Then eventually the screen started decaying as it started to tint as it looks almost equivalent to a photo editor when increasing the contrast. The third time I could login since it registered my keyboard again. So I checked my display settings and it reverted itself back to the normal settings.

I may upload another video if necessary. But this was a different attempt compared to the one described (this second attempt in the video was done for video purposes).

Update:
Here is the youtube link of what the decaying like glitch looked like:

Good call. Something is seriously screwy with this machine.

I definitely agree

Although I am not sure whether this information may help or not, I found the sheet that gives a broad description of what they did and what parts were replaced. It says verbatim:

Replaced Parts: HU LCD 15.6

Repair Actions: Driver Updated and/or Reloaded
Replaced Part
Performed Extensive Testing

I apologize if this information was needed earlier.

[SMG]

The Maintenance Manual I found indicates there is only one touchscreen available. (It must have been a different HP Envy I saw with a higher resolution screen.)

--15.6 in, LCD, FHD (1920×1080), antiglare, WLED, UWVA 100, eDP+PSR, low-power, flat, touchscreen display panel with narrow bezel; typical brightness: 400 nits

The only theory I have with why the screen output changed when they changed the screen is the replacement screen was from a different manufacturing batch that your original one.
____________________________________

The decaying color on the latest video may be related to backlighting. OLED screens do not require a backlight like other screens and having the overall color be darker helps prevent burn in. One does not want it to change on its own like that, but this computer model does seem to have a mind of its own when running Linux.
____________________________________

There are BIOS/UEFIs for some computers which only activate certain hardware functionality if they think Windows is running. There are some kernel parameters we can pass to in an attempt to get the UEFI to think Windows is running instead of Linux. Since this computer was originally a Windows-only computer and others are consistently seeing the same issue across multiple Linux distros, it's as if Linux is not getting or using the correct message about the display. For it to seemingly get worse as the kernel version advances seems quite odd.

I'm looking at the possible options to try as it will be a guessing game as to which kernel parameter (if any) might work. I will post tomorrow with a game-plan as there are few more searches I want to try.

Thank you for the effort! I will wait for your response.

acpi_osi='Windows 2020'

That's where I would start.

acpi_osi='Windows 2020'

I was debating that or 2015 as a start point given who knows what HP used as design criteria. Those two (2015 and 2020) match two of the four versions HP has listed for OS versions when getting drivers for this laptop on their website.

I admire your tenacity. I would have bowed out by now. The OP is fortunate to have you assisting with this.

[SMG]

I did find some HP Envys (2020) with a higher resolution screen (3840x2160), but those have a different Nvidia card (GeForce RTX 2060 Max-Q). Both were listed as having the screen working (one while running Ubuntu with the 5.8 kernel and the other running Arch with a custom 5.8 kernel). The third one on the list has the same Nvidia card as yours and lists the screen working running Ubuntu with the 5.8 kernel.

Because the issue is different with different kernels on your specific laptop and others are getting varying results, I'm still not completely convinced the kernel parameters to mimic Windows for ACPI will address the issue. Before trying that, I'd like to see some logs.

Please install and boot into the 5.8 kernel and run the following commands one at a time. They will send the information to termbin and return with a url address you should post for us. Each one will give a different url address. The first one is the start-up log and the second one is the X Server (which runs the graphics) log.
dmesg -T | nc termbin.com 9999
cat /var/log/Xorg.0.log | nc termbin.com 9999

Then return to the 5.4 kernel and run the same two commands to get two more url addresses.

Sorry I didn't see your response earlier. For the 5.8 kernel, here is the result for dmesg -T | nc termbin.com 9999

Code: Select all

And for cat /var/log/Xorg.0.log | nc termbin.com 9999

I will let you know some time later tomorrow what I may be able to glean from these. I'm hoping there will be something different between the two sets which indicates what might be happening.
