7.9: Black screen upon installation start
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 |

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'. |

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. |

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 |

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 |

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 |

So far:
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. |
unsupported hardware
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. See: https://forums.centos.org/viewtopic....332453#p332453 |
