Hi all,
I entitled this thread highlighting "conflicts".
I'm going to better explain why.
I have an HP notebook, i7 processor with an integrated video card: Intel IRIS Xe.
After, update, coded download and installation I noticed this problem:
1) if I don’t use the intel driver when I plug-in the HDMI cable nothing happens and no external monitoer is recognized;
2) if I use the intel driver when I plug-in the HDMI the OS recognize the external monitor (honestly not all monitor that I tested, but in genreal it works...) BUT some apps does not work. For example VLC has a full green video instead of reproducing the original video, Teams and Zoom continuously flashing the shared video during video calls. I did not test more apps but if necessary please let me know.
Then, in order to use the Intel driver, I installed it but I had to force them by editing the /etc/default/grub file
adding
GRUB_CMDLINE_LINUX=“i915.force_probe=4628” and
$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
Before this change, I had:
Code:
sudo dmesg | grep i915
[ 1.378303] i915 0000:00:02.0: Your graphics device 4268 is not properly supported by the driver in this
kernel version. To force driver probe anyway, use i915.force_probe=4268
[ 64.574579] snd_hda_codec_hdmi hdaudioC0D2: No i915 binding for Intel HDMI/DP codec
Is there a solution to use the Intel driver without force them?
Or is there the possibility to “enable” the HDMI with other drivers but having apps, like VLC, Teams and Zoom, that correctly works...?
After many days I was not able to fix this issue...
"Intel driver" is an ambiguous term. The Intel display driver has been deprecated for many moons. Check out the driver primer I wrote for explanation. Your problem is 15.4 was released without full Alder Lake graphics support. Enabling the backport kernel repo and installing the current kernel-default and any deps it requires from it should fix you up. This was initialized to address installing newer kernels, but remains incomplete. It stemmed from this Iris Xe issue. An alternate option would be to install the 15.5 alpha soon to become beta for final release end of May/start of June.
Dear mrmazda, thanks a lot!
Sorry for the ambiguity in terms of Intel driver, I used to work with dedicated NVIDEA graphic so far and I never encountered any issues.
When you mean the "backport" repo, I've already enabled them (but only "Kernel:stable:Backport.repo") and updated with packages. So I think it's not enough...
What do you advice to me: work on backport or install the 15.5 version (https://get.opensuse.org/leap/15.5/).
In the second option, installing 15.5, are those issues fixed?
Considering that is very annoying for me to "choice" if I prefer to have a PC that works without HDMI or have the external monitor but "video bugs".
Thanks
Edit:
If I want to try with the backport kernel, are these commands right:

What kernel version is your newest installed?

15.5 is a conservative upgrade from 15.4, largely to incorporate support for newer hardware than 15.4 supports, with limited changes in software versions. The initial version freeze in 15.5 is already past. I surely would expect full support for Alder Lake to be in 15.5 by the time it's released if it's not already. OTOH, I've seen reports of Alder Lake users content to have upgraded to the stable backport kernel. It really depends on your nature which route to try. I don't have Alder Lake, so there's nothing I can try. A year ago I did have trouble with Rocket Lake and 15.3 which got fixed in 15.4 before it was released, and in TW more or less immediately, similar trouble and timetable as you've encountered.
I tried to to update the kernel via backport repo.
I added the repo, via Yast installed the kernel backport version for install. Then reboot the system.
After reboot, shim opens (take care to have a root password without special characters!!!)
Then:
- enroll MOK
- continue, yes,
- enter password
- reboot
now I have:
1) the OS recognizes the my monitor (display.png); it’s very odd but does not work for all external monitors. For example in my office I have an “ACER CB282K” and when I plug in it in my PC it does not work and my PC’s display starts to flash... I tried with other monitors or TV and in those cases it works...
Is some ACER driver missing?
2) After this procedure is the same when I force the i915 driver. In particular I continue to see a green screen when I reproduce a video via VLC or the shared display via Teams/Zoom is flashing. See vlc.png and teams.png.
After the kernel update I tried also to add “i915.force_probe=4268” but nothing happens.
If you use inxi again before switching to 15.5A, do sudo inxi -U first to upgrade it from upstream. After upgrade to 15.5, best do it again. 15.5 doesn't have the latest either.
I upgraded to 15.5 Alpha and my monitor is not recognized yet.
Anyway, the "Display manager" is able to choose all resolution for the external monitor(s) but for mine it is useless because the display is flashing...
But VLC correctly reproduces video.
I'll try to create an istance in Bugzilla and let you know the answer.
@mrmazda, I was wondering if the "fan control" is related to the same HDMI issue, i.e. latest update of the operating system.
I mean, I searched online and I found two ways in order to set the fan options:
1) by installing "thinkfan", which I installed from https://software.opensuse.org/package/thinkfan but it does not work
2) by installing fancontrol-gui (https://forums.opensuse.org/t/any-fa...nsuse/135251/8), I've not found it for 15.5 yet.
Simply I want to set fan. I would like it starts not below 40 deg.
Sometimes the fan starts when the CPU is 33/36 deg and it's quite annoying.
Have I to wait some months for the last SUSE release?
I upgraded SUSe from 15.5 alpha to the 15.5 beta version and seems that nothing has changed.
Anyway I noticed other issues, I think related to the "video problem".
For example:
- if I'm on a video call with some apps like Zoom, Teams, or just reproduce a video with VLC and so on, whatever I try to do (use the terminal, open a pdf, open web pages and so on...) in the same desktop is getting very very very low, dramatically very low also turning on/off the caps lock the led is not responsive and it's possible to see the delay since you press the button and the led switches on/off...
Sincerely, I would like to ask you (I'm afraid to have a negative response) from your experience if that kind of problems (display, video, slowness in general) are simply related to some bugs and I/we have just to wait upgraded driver.
Or, it's related only to the integrated graphic board.
In the second case I'll change my HP notebook as soon as possible and I don't want to know anything more about integrated boards.
Honestly, I hope, and I'd like to think, that it is not a problem to be strictly imputed to the board, there are a lot of PC in the commerce with integrated graphic board.
At the same time, I think it can be ruled out is a hardware problem of my notebook (I hope).
As you can understand it's an annoying situation.
Best!

I don't believe there is any way to rule out a defective hardware issue. This kind of trouble is a price Linux users pay for buying hardware that's too new. Manufacturers provide drivers for Windows prior to product release, which very rarely happens for Linux use. Bugs appear in support for most new hardware. It takes time to find and quash them. Bug reports from users help with this process. With GPUs, they occur regardless whether discrete or part of the CPU package. Give the developers more time to address the bug if you can. Meanwhile, you could try a distro that more swiftly incorporates support for new hardware, such as openSUSE Tumbleweed. Very possibly TW simply works.

I've just tried the Windows partition. I've dual boot, no virtual machine or so on.
Also in Windows, all external monitors work except the ACER CB282K.
At this stage I think there is a problem only with that monitor. It's quite strange because it works with my old PC with Suse 15.2.
I tried to download Windows driver(s) for that monitor but I did not find anything so far.
With this information, can we rule out a hardware problem?
Can I do more tests in Windows to rule them out?
As you can image right now, the thing I'm most concerned about is being able to rule out a hardware problem.
Do you still have the old PC with 15.2, and does it still work with the Acer as an additional display, not as primary or sole? If the Acer is still under warranty, I would investigate the possibility of functional failure with Acer support.
IME, newer displays are more likely than older models to be cantankerous when they are not a sole display, but I think it also depends on the PC BIOS. Also IME, trouble is more likely from UEFI BIOS than older. They seem to be prone to poor support for legacy text modes used before the kernel's GPU driver starts a framebuffer. Also, behavior is not infrequently affected according to whether physically connected at POST time, which sometimes means need to be powered on as well.
Have you tried to discuss the situation with HP support?
I'm not sure, but I think the goal is to have another build of the beta released every two weeks or so. If I'm right, there could be another 15.5 kernel and/or Xorg in just a few days, since it's already been 10 since the last.
