It doesn't work for me on a HP ProBook 455 G7 with a Ryzen 5 4500U CPU and an integrated Radeon RX Vega 6 GPU. :( I hope, you are able to fix this, too. Keep up the great work, this tool has helped me a lot so far until I hit this AMD problem. |

Can you edit both grub.cfg files ( /boot/grub/grub.cfg and /EFI/BOOT/grub.cfg ) on the USB stick and add nomodeset as shown below. This will tell Linux to not switch between legacy frame buffer mode and the Linux Digital Rendering Manager (DRM). If it then works we know it's a DRM issue with the graphics. Thanks. |

I can't seem to get a working IMG-File after umpacking, modifying the grub.cfg files and rebuilding it with imgburn. It always tells me: No bootfile found for UEFI. Maybe the image does not support x64 UEFI. I'm using Ventoy.

I could be wrong, or misremembering, but I think there may have been some issue with imgburn. Rufus, I believe works fine. To be honest I'm 100% Linux so dd is the tool I would use. Maybe one of the guys who use windows can help out. |

For the record: I also tried burning the image directly to an USB drive. This time the nomodeset change doesn't seem to have an impact:
No further loading/booting

Hi there, sorry, couldn't get to it until now. I made the stick with Rufus and the Nomodeset added to both grub files. It boots to 100% but won't switch to the interface 🙁 Thanks again for the support, I really appreciate it!

Just a quick note to avoid any confusion regarding pre-release versions. This announcement relates to the version 23.1 as in v2021.08.2_23.1_x86-64_0.34 which now isn't the latest pre-release. The latest pre-release as linked to in my previous comment and at the time of writing is 23.3 as in shredos-2021.08.2_23.3_x86-64_0.34_20230604.img. 23.3 which has the feature that auto writes the dmesg.txt file to the USB stick. |

Some system bioses support selection of multiple video card devices, often there is three settings, one or two devices and an auto mode. If you have this option in your bios try booting ShredOS with each setting and see if one particular one works. I had this issue with a Dell PC system that just got to 100% then blank screen as it had the incorrect selection in the bios. Not sure if that really applies to a laptop but worth looking in the bios anyway just to be sure. |

Hi, I follow your instructions, but ShredOS won't create the dmesg.txt file. The newer version boots, screen turns black - I wait for a bit over half a minute then press Control+C and wait another minute. Then checking the UBS stick returns nothing. BIOS has no more GPU settings than allocating up to 512MB RAM to graphics. :( |

How easy would it be to install a distro like Ubuntu on this system? The only thing I can think of is to install a Linux distro, to confirm it will run Linux then grab the dmesg from Ubuntu, assuming it installed and booted ok. The Ubuntu dmesg would then give me an idea about what is being loaded, so I can check ShredOS isn't missing something. |

Very interesting thread about the same model here, well worth a read. https://forum.manjaro.org/t/impossible-installation-on-hp-455-g7-amd-renoir-4500u/26755/32 The final solution seems to be this https://forum.manjaro.org/t/impossible-installation-on-hp-455-g7-amd-renoir-4500u/26755/32 Can you make the same change in your bios and see if that works?

Me too. I was looking at ShredOS vs Ubuntu and in /usr/lib/firmware/amdgpu in Ubuntu there are 504 binaries while in ShredOS (/lib/firmware/amdgpu) there are 407. I can't find any other drivers except the fallback llvm. Without the dmesg I can't really figure out what is missing. Maybe when I update to the next buildroot, the buildroot guys will have included more amd drivers. |

@Hellgore1974 Ref. AMDGPU firmware With the latest version of ShredOS I'm pulling in LINUX_FIRMWARE_VERSION = 20210511 I can hopefully update this to LINUX_FIRMWARE_VERSION = 20230625 without doing a full buildroot upgrade. This version contains the missing 100+ missing AMDGPU binaries. I'll let you know as soon as I've created a new pre-release. |

Wow, that sounds really cool! Thank you again for all your work and support. ShredOS is simply the best secure erasing app out there and it would be great if I can continue to use it 👍

ShredOS doesn't make use of the x-org drivers, it first uses simple framebuffer support then the kernel switches to direct renderering manager (DRM) that handles the GPU. AMDGPU provides the DRM driver for AMD GPU's. That's as far as ShredOS goes, it doesn't need xorg drivers for a full window desktop experience. I hope that I don't need to install extra software just to get the AMD DRM to work properly as that starts to really add to the size of the build. It sort of wouldn't make sense to have to install that extra stuff just to get DRM for AMD working. What puzzles me is the nodemodeset command not seeming to work. This disables the kernel switching to DRM so Nwipe stays working with the simple framebuffer. However having said that I'm assuming you never see any text flash up on the screen even for a second which would suggest it never even manages to get the simple framebuffer working. That would imply it's failing very early in the boot. Do you see any text flash onto the screen momentarily before going blank? Here's all the DRM software, including AMDGPU enabled in ShredOS
I think what maybe useful, is to boot this system of a Ubuntu live USB stick or DVD. You don't need to install anything, just boot it to the desktop, then open a terminal and run dmesg. i.e |

One other thing, can you try this version '21' shredos-2021.08.2_21_x86-64_0.32.023_20220123.img This version is an older version from Jan 2022. This version doesn't use DRM software and keeps ShredOS & nwipe operating in the simple frame buffer mode. I just want to see if that works. If it does work, then it would indicate a DRM issue specific to that GPU that doesn't affect other AMD GPUs. |

Thanks. Just putting the graphics related sections of dmesg here for later reference: The kernel seems to be loading some firmware into presumably the GPU, VCN & DMUB using PSP.. what ever that means. However that 4 seconds into the boot, the simple/VGA/EFI frame buffer text should have already been displayed before it switches to DRM. EFI frame buffer is working because we see the Grub boot text and percentage, it should then switch to simple/VGA frame buffer which doesn't happen. (It does on Ubuntu) I did wonder if I was missing vgaarb, however booting ShredOS on another AMD system shows vgaarb gets loaded. I'll have to study this a bit more and get back to you. Having booted of Ubuntu you could still run nwipe from there of course with a |

If that doesn't get us anywhere, the only thing I can think of is to wait until I do a full upgrade of ShredOS to the latest kernel & drivers. |

One final thing, are you in a position that you can carry out these instructions. In the off chance the kernel is getting far enough to enable telnetd then there is the possibility to log in to ShredOS via the network and run dmesg. |

The laptop would need to be connected to a network with a RJ45/Cat5 network connection (WiFi doesn't work) and the network needs a router with DHCP enabled as ShredOS will request a IP address. |

Another black screen problem I found with the 5.13 kernel as used in ShredOS, black screen on AMD GPU. https://bbs.archlinux.org/viewtopic.php?id=267874
The workaround was adding amdgpu.dc=0 to grub. May be worth trying that. The ultimate fix was to upgrade the kernel.

I'm building ShredOS on the very latest buildroot 2023.05 and using the very latest kernel, v6.3. I'm not sure how long it will take, could be a day, could be a week. All depends on how many problems I have to solve. It's about time I upgraded ShredOS as the current kernel is nearly two years old, so will be interesting to see if it solves the blank screen problem on your HP ProBook 455 G7 / Ryzen 5 4500 GPU |

Thanks for letting me know. I'm currently building the new ShredOS 2023.05. This version will build both legacy and EFI, previous versions used a ShredOS script the produce the same effect so I need to make sure that works correctly. The build I did yesterday was way too large at 800MB, without going into all the details the buildroot conversion process added stuff that is really not needed, like gstreamer support ?? So once I've gone through all the packages and got the size back down to less than 180MB and checked the packages I do need are still there then I'll let you know. |

Tried the latest public release on an old Toshiba Satellite C55D laptop (AMD A8 processor and maybe video card?) using the USB image in both CSM and UEFI modes and after saying it was loading shredos, it would just hang and never finish, but the white text was still on the black screen. Tried the latest pre-release 23.5 and it worked just fine in UEFI mode. |

v2021.08.2_23.1_x86-64_0.34
Other software versions used within ShredOS for disc related operations
This is a pre-release version.
Notable changes in this release - ShredOS
Added missing AMDGPU, Radeon and GPU firmware. This was causing some systems to fail to boot to the nwipe screen.
Increased the vfat disk size from 80Mbytes to ~114MB to accommodate these new additions. This leaves about 11Mbyte free in the VFAT partition for logs and PDF reports. (PDF Reports will be in the v2021.08.2_24_x86-64_0.34 (v24) version.
Notable changes in this release - Nwipe
No changes. There will be lots of nwipe changes in the v0.35 release. HPA/DCO detection, PDF reports, ATA secure erase.
Note
As this is only a preview for testing booting on previously non bootable devices I'm not planning on creating .iso's or 32bit versions, unless somebody specifically has a system that for some reason they cannot boot using USB.
