Hello,

I'm using the following PC:

CPU: 12th Gen Intel(R) Core(TM) i5-12500
CPU Freq: 3000 MHz
RAM: 16384MB
RAM Freq: 2400 MHz

I'm trying to install 7.9 from a DOK (also tried from DVD)
I tried the non-graphic option which has the following boot parameters (also tried the default option)

linuxefi /images/pxeboot/vmlinuz inst.stage2=hd:LABEL=CENTOS\x\
207\x20X8 xdriver=vesa nomodeset quiet

initrdefi /images/pxeboot/initrd.img

When I chose this option I got a black screen.
I tried several solutions I found in Google, but non of them solved the issue.

Can you please advise ?

Thank you,
Zvika

I'm not a CentOS user, so I may be confused or lacking important data, but Distrowatch has no 7.9, only 7.8 from nearly 3 years ago, and 8.5 from around 16 months ago. That to me means you must be trying to install a 2 or so year old distro on a system with a CPU born about a year later. That's a recipe for black screens if ever there was one. The general rule for hardware for use with Linux, unless you are a kernel or other fundament developer, is to pick a release that's several months to a year newer than the hardware. You're apparently trying to do the reverse. If you want to run an i5-12500 on Linux, you need a kernel that supports it. It looks to me like that would be 5.17 or newer for full support, and corresponding age of firmware and graphics hardware provided by the release.

Assuming you are in fact using a distro that supports your hardware, nomodeset must be eliminated for maximum compatibility in an installed system. Nomodeset disables KMS, which all fully competent FOSS graphics drivers depend on. xdriver=vesa also needs to go probably, though it might be supported only by the installation system, thus inert once installation has succeeded. Nomodeset is often required for a distro installer to work. Most of them are sufficiently bling free that they are adequately functional with a crude basic driver like VESA.

Intel Gen 12 graphics is a pretty significant change from prior generations of Intel graphics. It might be that even VESA support didn't yet exist for it in the installation system you're trying to use. I suggest trying a current rolling release, or an alpha or beta release, of something that is sure to have a very recent version of Intel Graphics support in both kernel and X, something newer than spring of last year.

Hi mrmazda,

Thank you very much for your reply.

I tried to remove: xdriver=vesa nomodeset quiet
and got the same results.

Do you think there is a way to use this old distro with another value to xdriver ?

Best regards,
Zvika

...and....
So we're back to where we've been for years now:

1. You don't tell us what kind of computer/hardware you're using. Telling us about the CPU and RAM is near pointless, since it's the REST of the hardware that makes a difference.
2. You claim to be a kernel developer, with a 'team' working on some sort of SBC and custom hardware, but don't ever tell us anything past that
3. You've posted several things that are VERY similar
4. You tell us you've tried 'several solutions', but don't bother telling us which ones
5. You have a graphics issue, and tell us nothing about your graphics hardware/monitor/etc.

So what, exactly, do you think we're going to be able to tell you??? See any of your previous threads about similar issues:
https://www.linuxquestions.org/quest...ot-4175708180/
https://www.linuxquestions.org/quest...ga-4175719035/
https://www.linuxquestions.org/quest...on-4175697514/

A kernel developer who has been working for *FIFTEEN YEARS* should be able to provide details about the hardware they're working on easily. But didn't you say two years ago that we "don't need to know" about your hardware???
https://www.linuxquestions.org/quest...5/#post6300746

The CentOS forums say to try "nomodeset text", which forces a text-installer; again, you still say nothing about your graphics hardware or give any useful details, or tell anyone what you've done/tried past looking at 'several solutions'.

Except for the RAM part, not true. Yes, RAM is pointless. i5-12500 says Launch Date Q1'22, Intel® UHD Graphics 770 and much more, which some of us know without looking it up.

As to whether another value for xdriver might work, I have no idea without knowing what "7.9 from a DOK" is so to look up the instructions that are provided for using it.

Good catch. Given the OP's posting history about his 'devices' and unwillingness to provide details, I didn't do much research honestly. Also, they have claimed to have been trying to get things like this working on an SBC (?), but won't provide details about it.
Agreed; no clue what they mean by DOK in this context, but for all we know they're having graphic issues because their screen itself can't get the right frequency/refresh, and is going dark.

Hello,

DOK is : Disk On Key. This is the media that contains the ISO of Centos 7.9 burned with Rufus.
Also tried to install from CD and got the same results.
There is no "SBC". It's a PC with an ASUS motherboard.

Can you please tell what further info is required ?

Thank you,
Zvika

So a USB drive, then??
Sorry, but are you not reading what you're told, or not understanding it???

You've said many times in the past it's an SBC you're working on, with custom hardware and drivers. Now you're saying it's a generic "PC with Asus motherboard"? Almost as pointless as what you posted to start. Why can't you tell us the brand and model number? You were asked specifically about the monitor/graphics hardware, and given an option to try earlier...did you read those things?? Because you haven't acknowledged the advice given or answered those questions. Again, this is much like most of your previous threads...you are asked specific questions and either don't answer them or tell us we don't need to know.

You claim to be a kernel developer with fifteen years experience, but can't seem to answer very basic troubleshooting questions. You claim to have a 'team' working on things, yet can't seem to get anyone on your team to help you either???

Answer the questions asked, and provide actual details. Otherwise, as you've been told before (MANY times), there isn't much point in posting.

Hello,

In the past it was another issue, with different hardware.

Now it's a home PC. It's not a standard DELL of HP PC.
So it does not have a brand and model number.

It's a PC assembled in a PC shop with COTs hardware like ASUS motherboard.
In earlier post I wrote some critical data from BIOS.

Thank you,
Zvika

AGAIN: the motherboard has a model number, doesn't it??? And AGAIN, you were asked about the video hardware and components...and still don't answer. All you've told us is that it's one of a LOT of different Asus motherboards...which tells us absolutely nothing. And even when asked about the video components, you don't answer....for the *THIRD TIME*
Which 'earlier post'??? Not this one, that's for certain. And none of the messages you posted were ANYTHING to do with BIOS.

AGAIN:

1. You were given an option to put on the boot line and don't acknowledge it, say if you tried it, or what the results were
2. You were asked about the video setup, and still say nothing
3. You were asked about the hardware, and we got nothing past "Asus motherboard".

Pay attention: EITHER PROVIDE DETAILS OR NO ONE WILL BE ABLE TO HELP YOU. Either participate, or there is no point in posting anything, anywhere.

I answered for him with the link in post #5. He has Alder Lake UHD Graphics 770 introduced Q1'22 supporting up to 7680 x 4320 @ 60Hz. Intel IGPs support up to three outputs.

...which he may or may not be actually using, right? Could be using an external video card (nVidia? AMD?), and it could be his monitor can't support the sync rate (which is why I asked about that as well). The OP may very well be using the onboard ports...and may not. And we don't know WHICH Port is being used either...could, by default, go to a different video output for console/tty1. Using displayport versus HDMI/DVI may be the problem...but we don't know, because the OP won't answer. We still know nothing past "Asus motherboard", which we had to ask a few times to get.

Hi TB0ne,

Can you please guide me how to get extra info required to solve this issue ?

The on board video has 2 output ports: VGA and HDMI
I tried both.

I have no external video card installed.
Is there any info in BIOS that can be helpful ?

Thank you,
Zvika

No, I don't think anyone can 'guide you' for this, since you don't appear to be paying attention.

So far:

1. You were given a command line option to try; you haven't even acknowledged reading it, or told us the results if you did try it.
2. You were asked about your monitor or if you see ANYTHING on it, such as "Out of range", or sync errors...and you have said nothing.
3. You were asked about the video setup, and you now mention VGA and HDMI; great. How are you plugging into the monitor?? Same cables? Adapters? What?? Tried a different monitor??
4. You were asked about the model number of this Asus board...and haven't told us anything about it other than "Asus".

Since you won't answer questions, there's nothing anyone can help you with. Want to know about BIOS options? Then *YOU* can read your owners manual and look them up yourself. Basic troubleshooting, diagnostics, and answering simple questions should be easy for someone who claims to have sixteen years experience as a kernel developer, and who has a 'team' working on specialized hardware. Instead of CentOS 7, have you tried loading SOMETHING ELSE just to test with??? Or the latest CentOS Stream??? What have you actually *DONE* to try to get this working besides turn it on??

Either answer the questions or don't bother asking; this is the same thing you've been told in a LOT of your other threads, where you ALSO don't answer questions/provide information. Not sure why you think that's a good thing to continue doing.

I had the same problem.

I couldn't install centos 7 only centos 8.
I'm still looking for a solution to this problem.
I haven't tried installing Rocky7, I'll do that in the future.
