shredOS terminal compressed to top line of screen on multi GPU laptop [fixed] #52

Is there an option in the BIOS/UEFI setup to change from UEFI mode to Legacy/BIOS mode? |
|
shredOS works on my other laptop and on my desktop pc (both have older hardware than the new laptop). I was hoping to use shredOS to wipe all 3 machines. :o I just don't have much knowledge about how hardware and bootable software needs to be programmed to work. Laptop is UEFI boot by default (tested boot with secure boot on/off). For some reason, I'm unable to switch it from UEFI so I'm under the impression this BIOS doesn't support legacy? I'll look into this now. |
|
Apparently, I should be able to change the boot setting to legacy after setting a password (which I tried). However, I'll try a bit more right now as I have the laptop currently with me on the desk. |
|
Sure. Give it a try and let us know. |
|
If this document applies to your model you may have to enable a setting that trusts the USB device to boot UEFI, not only that but the actual file name. |
|
Also, this is the BIOS except mine says v2.02. I got this image from google |

Acer A315-53G Service Manual https://www.manualslib.com/manual/1780777/Acer-A315-53g.html?page=55#manual |
|
Possibly under 'advanced settings' |
|
It says, on this BIOS system you can press CTRL+S on the tab "Main" in advanced settings to access special settings regarding SATA mode (which is apparently needed to switch it to legacy). I've changed it from RAID to AHCI and still unable to change the boot mode to Legacy. |
|
https://community.acer.com/en/discussion/615614/no-sata-mode-in-my-bios-predator-helios-300-ph315-53 tried this for help but doesn't seem to let me switch the boot mode. :/ |
Any luck finding this setting that lets you set a trusted UEFI device? |
|
I've added the .efi to the trusted files for execution and it does the same thing. It boots to a black screen and then shows: RecalBox |
|
EFI file boot 0: shredos it's now displaying the file in the boot priority. i've named it "shredos". set shredos to 1st slot in priority order. selected f12 to choose from boot order and attempted booting shredos. loads a black screen and then shows: RecalBox |
|
Has it got two discs in raid configuration or two separate device in non raid mode. Nwipe in shredos will only work in non raid mode. It's also possible shredos doesn't have the latest driver, however if you loaded ubuntu 18.10 on it and it worked then shredos should work too. |
|
I'm able to switch it between the SATA modes: ACHI Same issue happens on all settings. And I'm unable to switch it from UEFI to Legacy no matter what SATA mode I choose. I haven't tried installing Ubuntu 18.10 or later so I will download Ubunutu now and format it onto a USB to see if it works. Note: This laptop was bought with Windows preinstalled on it and has the product key on the hardware (It wasn't manufactured with Linux on it and has never been tested with Linux on it). I'll begin the process now. |
|
Currently downloading https://old-releases.ubuntu.com/releases/18.10/ |
|
Just a quick example of what the hang looks like when I boot. I made it in Microsoft Paint while waiting for Ubuntu to download. |
|
Update regarding Ubuntu 18.10: Currently using Rufus to format Ubuntu onto a USB. |
|
This is basically a known issue. See #34 and #48 (comment) So far it's happening only on very new devices unless more reports are coming in from other people reporting the opposite. |
|
Ubuntu 18.10 successfully installed. I will check the comment links now, Firminator. Thank you to both of you for helping me try to solve this issue and then further explaining that it's likely due to it being a very new device. |
|
I've noticed that shredos is lacking the /device/fb0 ( the frame buffer ). That used to work as I had used fbgrab etc to grab screenshots in the past. I've got a feeling the frame buffer may have got disabled when I started loading video drivers. Before I build tonights shredos I'll take a look at enabling the frame buffer. That would certainly cause this problem. |
|
Ryan, |
|
Just wiped Ubuntu off it. I'm also not sure what an NVMe drive is. If NVMe means "do you have an SSD in your laptop?", I have a 1TB SSD installed on the laptop. |
|
By the way, the main post of this thread is like half wrong because I accidentally posted specs for a different laptop. My laptop is the ACER Predator Helios 300 15.6" Gaming Laptop - Intel® Core™ i7, RTX 3070, 1 TB SSD. I accidentally posted Acer Predator Triton, which isn't the same laptop. I've edited the main post now so it's correct. |
|
Can you try this version of shredos. It's a version prior to me adding the video drivers and so the frame buffer may be working |
|
I will try it now. :D |
|
Crashed again at this screen in the same way. RecalBox |
|
Yes same here. |
|
I just checked, the frame buffer isn't available in that version either. I'll go back further and check an earlier release. |
|
Mine is 11th gen Intel Core aka Tigerlake and it comes with this GPU: |
No. They don't finish booting at all. Just showing Recalbox and/or blinking cursor. I tested on 2 different devices that only have Intel CPU w/ GPU and no other GPU. I have a lot of different devices that I can test on, but it's getting confusing now. As of now I think the issue is limited to Intel GPU not being recognized which could be addressed by testing different drivers, kernel, and grub settings. This surely is a rabbithole. Adding SSH might be a good idea, but that would only help if the system actually finishes booting. As I see it some of the devices I tried on just freeze or (not visibly) crash. |
Yes I think that's our best bet for now. Take it easy. We don't need you burned out. Thanks for providing ShredOS to us. I wish I had more experience and time to mess with configuring and compiling buildroot to help out here. Maybe over time I get a hang of it but it surely is a steep learning curve. |
|
also, you said something about Nouveau. the funny thing is, when i was installing ubuntu there was an initial kernel screen with 3 lines of text before the OS loaded and one of the lines said something about Nouveau. i can't remember what it said though, would you like me to download ubuntu 18.10 and reinstall it to see the exact message? |
That will be for the Nvidia card. If you think it might of said something about the Intel GPU it might give us a clue. Trouble with open source there's no revenue stream otherwise I would go out and buy the same laptop as you so I had something to work on. |
Thanks, I also don't want to get too side tracked by ShredOS when I could be adding features into nwipe. I can add features far quicker to nwipe than I can diagnose weird kernel driver issues. That's not to say I don't want to fix those issues just itching to finally get secure erase and HPA/DSO into nwipe. 😁 |
|
Yes, I'll look into that. It may help. |
I'm with you. We'll get the ShredOS booting issue figured out eventually. Bunch of people here on Github that might jump in and help. |
|
On this one particular machine I was testing this morning I finally drilled it down to one setting in the BIOS: CSM support. 2 additional settings I used:
The thing is that more and more (modern) platforms have no Legacy mode anymore, and are UEFI-only... unless you coreboot'ed them to free them from the shackles :) |
|
That's interesting, it would imply there's a more pure UEFI, maybe one that's signed by Microsoft?, but then you would have thought that was what the secure boot switch was all about. I wonder what CSM is actually providing compatibility for? |
|
CSM is magic. That's all I know. Support for older hardware. There is probably documentaion on the UEFI.org site, but I never bothered to read this. I think this might just be a buildroot issue. The way it's compiled or build. And what settings have to be set. I looked at this once and found this pretty intimidating. Is buildroot your choice of building the underlying OS and you would never consider abandoning it? I'm asking since I looked at other projects in the past and found some that looked promising.
|

I've also used cubic in the past to built a Ubuntu live that contains the latest nwipe. Cubic I could also build a custom gparted live however the USB size is about 300MB compared to the current ShredOS of 51MB. I do like how small and fast ShredOS is and I'm quite familiar with working my way around buildroot. I've just got to figure out why some Intel hybrid systems don't boot. I've got about 10 different PCs/laptops to test on and all except that Sony VAIO boot ShredOS perfectly but none are newer than 5 years old. Even boots perfectly on a MAC. There's been a lot of updates to buildroot since the 2020.05 release so fingers crossed maybe an update will help. I'm planning on updating to the 2021.08.02 release sometime next week. |
|
One other thing about the most recent releases, I noticed that a 10 minute screen saver (blank screen) had some how become enabled. Press any key to un-blank. I don't know whether you've noticed that? |
|
Interesting. I know of gparted live (but had no idea that you can build your own). Never heard of Cubic ( Custom Ubuntu ISO Creator ) but it's appealing. I'd take a look at both and see if I can get something going just to gain some experience. Yocto seemed to have a steep learning curve, while minimal linux might be something I could get going. Sounds like you have enough devices to keep you busy with testing. Glad you know your way around with buildroot. I was definitely overwhelmed with all the options in there. Had no idea that it works on a mac, too. I haven't noticed the screensaver yet. Since all the changes with adding framebuffer drivers I wonder if some default video/screensaver setting got enabled. Maybe revert back to the old build? |

@Firminator I'd rather not revert back to the old way unless there is a big disadvantage to using fbdev. Having /dev/fb0, fb1, fb2 etc enables the following features that weren't available before:
How to make a persistent change to the terminal resolution in Shredos With the systems that just show the RecalBox and nothing else and also Ryan's problem with the terminal compressed to top of the screen, I think it's got everything to do with the system switching the framebuffer from the embedded Intel GPU to the secondary GPU. From what I've read so far, using the correct software we should be able to access the frame buffer correctly for the secondary GPU. When we see the Recalbox message, I think it's quite possible nwipe is running in the secondary framebuffer that we're not seeing. Apparently in some BIOS's you can disable one or the other GPU so it doesn't perform the switch, i.e it continues to use the same framebuffer it started with. @Firminator @Ryan-A-Bradley Something that suddenly occurred to me. Does you laptop have a HDMI output? And can you plug that into a monitor? I was just wondering whether you would see nwipe appear on the HDMI output and the blank RecalBox on the laptop screen ? |
|
@Firminator Are any of those systems you have that just show the blank Recalbox screen, do they happen to have a discreet secondary GPU that can be removed? If it then works it would seem to confirm there is issue accessing the secondary framebuffer. If I plug a secondary graphics card into my Dell which has onboard graphics, even if you connect a VGA lead to the on board graphics saying something to the effect that you have a secondary card, you can't connect to the onboard GPU. Maybe some bios's don't bother giving the user that warning so you are left wondering why your screen is blank after the initial boot up text. With the Dell I think you can override auto selection of the GPU and just use embedded or onboard. |
|
if it does have HDMI output (which it probably will), i'll be testing it later on today connected up to a monitor. |
|
The devices I tested on have no secondary GPU. Just Intel GPU. The Recalbox message and then I also tested on a device with an NVIDA card and no Intel GPU and ShredOS boots fine. But this device has no UEFI, so it's no surprise. The other issue (this thread) is multi GPUs (NVIDIA or ATI AND Intel GPU build-into CPU). I guess you can test that using an HDMI output. That's a good idea. I don't have a device to test this currently. |
|
#34 reported the same I'm now realizing (edited my comment above also). Turn CSM off and it fails to output video. Turn CSM on and it works. Regardless this is an UEFI problem since most recent devices are UEFI-only with no CSM option in the BIOS anymore. |
|
I'm hoping the new frame buffer software will fix this, if not I'll need to dig deeper into Recalbox and possible alternatives like clover. On a different subject, as I've been working through the new build, I realised previous version had the hibernate code (sleep to disc) installed, rather than sleep to RAM. Important for unfreezing SSDs and may have been why I was having problems with waking from sleep as part of the SSD secure erase process. |

@Ryan-A-Bradley Can you download this .img file. Shredos 2021.08.2 legacy and UEFI bootable It's the latest 2021.08.2 development release. It should hopefully resolve this issue. Please let us know how it goes. Thanks. |
|
@PartialVolume it's fixed! working 100%. i'm even using it to wipe the other laptop right now. thank you so much! :D |

@Ryan-A-Bradley Excellent, glad it's working. |
|
Just to clarify for others reading this. This problem is fixed in the development version 2021.08.2 of ShredOS that hasn't been officially released yet. The development version will be officially released in the next few days. |
Thank you for fixing this! :D
