grub update blanks login

Post by fibrou »

grub was updated after performing automatic software update, but I can no longer see anything after boot. The only way I can get into my system is to go through "Recovery Mode." I had TimeShift on, but when I restored, nothing happened - same problem. I must have 'killed' something, because after tinkering, I was not able to get system to allow me into the grub menu, so I did what I hate to do - reinstalled LinuxMint. After getting most of my software updated, I am able to use my system through "Recovery Mode," but graphics are simply not set. System indicates "graphics drivers are not loaded," but when I attempt to "update drivers," response is that all is updated, nothing to load... Bottom line, though, is that system thinks my display is a laptop, and sets accordingly. I cannot change resolution, or any graphic setting.

I enclose output from inxi -Fxxxrz.

What additional information can I provide the Community to help you help me?

If you reinstalled and did not install the grub update which caused the original problem, then it is likely something other than grub is the problem.

You have very new equipment. I recommend you switch to the 5.8 kernel which is available in Update Manager.

Open Update Manager. Select View > Linux Kernels and click Continue. Make sure 5.8 is selected on the left panel and then click the top-most option on the right panel. An "Install" button will appear. Install the kernel and then reboot for it to become active.

Did you try installing graphic drivers from this repo? The graphics drivers for your gpu are included in the kernel. Only if there are problems should one consider using the drivers from the AMD website. Considering you are currently having issues, I suggest removing these.

Code: Select all

           Active apt repos in: /etc/apt/sources.list.d/amdgpu-pro-local.list 
           1: deb [ trusted=yes ] file:/var/opt/amdgpu-pro-local/ ./
The newer kernel will give you newer drivers. Maybe that and removing the anything extra you added will be all that is needed. However, it is possible firmware or kernel parameters might be needed to get the graphics working properly.

Re: grub update blanks login

Post by fibrou »

Thanks!

I have just installed kernel 5.8.0-43, which won't take effect until I reboot. My biggest fear is getting the "blank screen of death" after reboot. I will let my nerves "calm down" for a couple of hours, and try again this afternoon.

Before I reboot though, what do you mean by:

"However, it is possible firmware or kernel parameters might be needed to get the graphics working properly."?

My apologies, but my newbie-ness is showing... Yes, this is a new machine - have had it for only 2 weeks, so my nerves are a little on edge. Other than that "weird" behavior after the grub update, I haven't had any problem with the machine. Very nice.

Thanks again for the suggestion.

The only way I can get into my system is to go through "Recovery Mode."
Recovery mode disables all the graphic drivers and prevents them from loading from the kernel. You have to boot normally to get graphics drivers. Notice the N/A below which should be amdgpu and the missing driver and the incorrect renderer. This has nothing to do with the system thinking you have a laptop.

Graphics: Device-1: Advanced Micro Devices [AMD/ATI] Navi 10 [Radeon RX 5600 OEM/5600 XT / 5700/5700 XT] vendor: Gigabyte
driver: N/A bus ID: 0a:00.0 chip ID: 1002:731f
Display: x11 server: X.Org 1.20.9 driver: ati,fbdev [missing amdgpu] unloaded: modesetting,radeon,vesa resolution: 1024x768~76Hz
OpenGL: renderer: llvmpipe (LLVM 10.0.1 256 bits) [should be AMD RX name of your card] v: 3.3 Mesa 20.1.6 compat-v: 3.1 direct render: Yes

If that works out, here is the link for the ISO with the 5.8 kernel Linux Mint 20.1 "Ulyssa" - Cinnamon (Edge, 64-bit). The newer kernel should install newer drivers for you card and hopefully that will take care of the issue.

If you get the blank screen, then on the next boot when you boot into recovery mode, we'll want to check the logs from the prior boot to see what happened.

You can use this command in a terminal to upload the journalctl file of the prior boot to termbin:
journalctl -b -1 | nc termbin.com 9999
It will return with a url address that you can post in a subsequent reply.

I just saw the 5600 and didn't notice you had Navi 10 listed. Was working on a different thread with a 5600 and it had Navi 14. Here is a thread with a different GPU, but the firmware is explained Drivers for AMD 6800XT. I do see a listing for Navi10 on the external link, but we'd want to see the messages in your log before doing anything with that.

Yep, booted into never-never land. Had to press ESC to login to Recovery mode. I ran the command, and it yield the following web site: https://termbin.com/z3u4

I am not sure if I am reading the output correctly, but the indication is that I am running 5.4.0-26-generic, but according to the update manager, I am running 5.8.0-44 (see attached).

Am I reading that correctly?

If you booted into never-never land and did not shut down in between doing that and pressing escape, then we would want to see the current boot information and not the prior boot information. I presumed you were powering down to restart which is why I gave you the command for the prior boot. Here is the one for the current boot.

You are reading it correctly. However, if you are pressing escape to get to recovery mode, that seems to indicate there is a problem just getting into grub and not with the operating system's graphic drivers starting (which is what I thought might be the issue).

I'll see what I can pick up from the logs.

1. Yes, I am powering-down, then powering-up. I have to press ESC after my bios shows on screen to get into the "grub" menu.
2. Output from the "current boot" command can be found here: https://termbin.com/0drg6
3. Update manager wants to upgrade my 5.4 kernel (see attached), but doesn't 5.8 supersede 5.4? Is there a conflict with those two?

Thanks so much for your time and attention. I am simply boggled as to what is going on. Main reason why I am blaming "grub" was because of the automatic update that generated my "blank screen." I did not immediately think it was my graphics driver, but I have had problems with drivers on another machine (running Ubuntu), so I thought it might be with the AMD vs. Nvidia situation, e.g. new machine is using AMD Radeon GPU vs Nvidia model.

Yet the 5.4.0-26 kernel booted. :shock: Did you select that kernel to use on a prior boot?

Are you 100% sure the operating system is booting when it goes to the blank screen? I helped someone on a different thread who was switching from an Nvidia GPU to an AMD gpu (or maybe it was vice versa). Turns out the gpu to which he was switching had a higher power requirement that the previous one and the power supply was not able to output enough power to get everything booted. However, if I recall correctly, he was not even able to boot into recovery mode with the new one.

Only one kernel can boot at a time. You can have many kernels installed at the same time, but only one is Active. The highest number kernel will boot unless you boot into grub and choose a lower number (older) kernel. Therefore this is no conflict; kernels just take up space on your drive.

Have you ever been able to boot without using recovery mode? Is it only since this grub update that you had to start using recovery mode?

Are you able to boot into a live session with your ISO usb without using compatibility mode?

I did not manually select any kernel until 5.8

Well, the machine was booting yesterday, but when the screen went blank after the grub update, I rebooted into recovery mode. BTW, this machine used to be dual-boot with Windows, which I thought was a problem, so I reformatted everything this morning to remove the Windows partition, and only have LM, but problem persists.

I am only able to boot from the ISO using "Compatiblity" mode... If I select the first option, boots into dark never-land.

How else can I help you help me with this problem?

There are a couple of odd things about this log. The first, as you noted, is it used the 5.4.0-26 kernel which is default kernel for the LM20 install ISO. In your Radeon Utility Error thread you indicated you installed LM20.1 which I thought meant you used the LM20.1 ISO. I am not aware that kernel exists on the LM20.1 ISO. (The correct graphic drivers were showing on the inxi info in the Radeon Utility Error thread.)

The other odd thing about that boot log are are the times in relation to the times of the second link you posted. The elapsed time from start to finish is just under five minutes:
start - Feb 23 15:42:50
end - Feb 23 15:47:30

For this log, which did not have an official end because termbin has a size limit and it could not include the entire log because you were still running, the start and end times were before the times of the prior log. :?

start - Feb 23 12:44:31
end - Feb 23 14:26:38

Both logs mention using nomodeset because recovery mode was used. I wanted you to see the log messages related to that so you understand what happens when using recovery mode.

Code: Select all

Feb 23 12:44:31 jpbBoomer kernel: You have booted with nomodeset. This means your GPU drivers are DISABLED
Feb 23 12:44:31 jpbBoomer kernel: Any video related functionality will be severely degraded, and you may not even be able to suspend the system properly
Feb 23 12:44:31 jpbBoomer kernel: Unless you actually understand what nomodeset does, you should reboot without enabling it
This second log also mentions:

Code: Select all

Feb 23 12:44:54 jpbBoomer systemd[1]: Reloading.
Feb 23 12:44:54 jpbBoomer systemd[1193]: /lib/systemd/system-generators/friendly-recovery failed with exit status 1
I do not know enough about recovery mode to know what it might mean.

Is Windows still listed in the EFI menu in BIOS/UEFI?
Was Windows and Ubuntu/Mint both listed in grub for the original install?
Might there have been any Windows update done before you did the grub update that resulted in the blank screen.

No, and Yes.

I believe I had to upgrade from LM20, so not an ISO, but I will make one.

You can not remove it. It is what happens when you use recovery mode. That is why no graphics drivers are installed when you use recovery mode.

That would explain the 5.4-0-26 kernel.

If you are going to make a new ISO, I would suggest trying the Linux Mint 20.1 "Ulyssa" - Cinnamon (Edge, 64-bit) as maybe the newer graphics drivers in the 5.8 kernel might help.

ISO made, and still, does not "Live Boot"... I can only go through "Compatibility Mode." :cry:

I wish there was something I could do. I did a full-flush install last night, and I am willing to do it again, but I really can't see a reason. Is there any other way?

When you originally tested the ISO, were you able to boot without using compatibility mode?

The info you posted in the other thread seems to indicate the 5.4 kernel worked. I do not know what might be different unless maybe something happened hardware-wise on your system?

I'm not sure what you mean..."originally tested the ISO..." I have not been able to get into the system since "grub update" blanked my boot without going through compatibility mode.

However, when I initially installed LM, dual boot with Windows, it appeared to be working fine. It is only after the grub update - middle of day Monday - that things have gone haywire...

Before installing LM, it is good practice to run Mint in a live session to make sure everything works.
There are people who install Mint without testing it first, so it is possible that is what you did. When you booted LM to install it, did you have to use compatibility mode?

Grub is software which is installed on the computer's hard drive. You have reinstalled Mint which should have reinstalled a new version of grub, so I do not know what happened during that grub update that is make your computer have problems. When you boot the Mint ISO, Mint is not using the hard drive. That means it is not using grub on the hard drive. However, it is using all the rest of your hardware.

When I first installed LM - in dual boot with windows - I was able to boot off the USB without using compatibility mode. Everything ran wonderfully for almost two weeks, until yesterday (Monday, Feb 23) when a grub update occurred. I too do not know what happened, but I do know that after I returned from having my machine down from afternoon errands, system would NOT boot unless I went through Recovery Mode.

I agree there is something "weird" here, but the recent full-flush install I just did last night should have "fixed" whatever grub problem there was shouldn't it?

BTW, what gets me the most is the inability to boot off the USB ISO without having to go through the second "Compatibility" option. Why does it only boot through the compatibility option? :?
