Unable to install Ubuntu 18.04 on AMD Ryzen 2500U with Radeon Vega 8 Gfx

  • 772

I'm trying to install Ubuntu 18.04 (18.04.1 will try tomorrow) onto Acer Aspire A315-41-R8XR. I have unpacked iso file to my flash and booted to grub successfully, but when I select "Try Ubuntu", I just get black screen and that's all. I have also tried to select "Install Ubuntu", but I get many errors:

enter image description here
Google: watchdog: BUG: soft lockup - CPU#1 stuck for 22s! [migration/1:15]

Windows 8.1 works fine, although it was already on the disk from another notebook, so, I think, it is not a power supply problem.

I've seen many such posts in the internet. It seems that people lost Ubuntu on Ryzen with Vega...

How to fix? May be use newer kernel? How to do it?

  1. My solutions: In my case, i edited quiet splash to nosplash (delete the quiet) and viola! it works.

    Story: Just recently installing Ubuntu 18.04 in along Win 10 (dual boot) in my HP Envy x360 13 AMD Ryzen 5, probably just the same with your Laptop. After struggling several hours trying all the solutions i found in many forums, but no luck. It seems that the solutions, depends on what error is occured when you install Ubuntu. in my cases, it said: screenshot error

    Several things i've tried , but failed:

    1. add `nomodeset`
    2. add `noacpi=off`
    3. add `amdgpu.dpm=0`

    btw, do not forget that, if you install your Windows in UEFI, then u must install Ubuntu in UEFI mode too (cmiiw). UEFI - UEFI, Legacy - Legacy.

  2. first boot using nomodeset as kernel parameter, to do that boot in grub press e then add nomodeset after quiet splash then press F10 to boot.

    If you are in legacy mode then select options and then check nomodeset.

    then upgrade to latest mainline kernel or kernel newer that 4.19.0 and reboot.

    kernel 4.19.0 included with support for ryzen mobile series and vega graphics however implementation is not yet complete you will experience random freezes at least once a day.

  3. I had the exact same problem, there is some error in BIOS, I followed instructions from this article:

    http://kulminaator.blogspot.com/2018/06/linux-on-amd-ryzen-2500u-powered-laptop.html

    in grub menu while booting press "e" to edit booting parameters and edit as specified in the link.

    It worked for me. Good luck! ;-) D.

  4. In Windows, insert the Ubuntu ISO image and open file explorer. Locate the boot folder and open the Grub config file with NotePad++. Edit the bootline of Try Ubuntu and/or Install Ubuntu : Locate the linux line,add a space at the end and type iommu=soft . Save, wait and exit. This change is permanent and it allows you to boot and compile custom Kernel (Ubiquity hot fix).

    Example for Mint Tessa Compatibility Mode bootline:

    linux    /casper/vmlinuz  file=/cdrom/preseed/linuxmint.seed boot=casper xforcevesa iso-scan/filename=${iso_path} ramdisk_size=1048576 root=/dev/ram rw noapic noacpi nosplash irqpoll -- iommu=soft

    NB On Ryzen 2700U here, Linux ISO's will boot that way only.

    cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.0.0-050000rc7-generic root=UUID=b6976dd1-ba78-4edc-9b49-4af79a979223 ro iommu=soft quiet splash vt.handoff=1

  5. I was having the same issue while trying to install any linux distributions in my new Dell inspiron 15 5000 5575.it also had the same AMD Ryzen 5 2500u processor and radeon vega 8 mobile integrated graphics.. i tried all the above methods but nothing worked for me.i asked in several showrooms and service centres to install linux.but they all said kali can't be installed in amd radeon combo.sometimes ubuntu can be done.

    i tried : nomodeset acpioff make usb boot in various types tried all command line and grub mode methods no graphics and safe modes

    atlast i decided to update my bios.i downloaded and installed latest bios update for my dell pc which also noted that it enables the linux compatibily of my laptop .. DO IT WITH YOUR OWN RESPONSIBILTY!! and after bios uodate .. now all the linux distros work very smoothly.and i use a dualboot of ubuntu 19.04 and windows 10 .. i also checked if i can install kali and parrot.it also works.

  6. when booting to installation media, select E for edit, then replace quiet and splash with:

    noapic nosplash irqpoll

    Once booted and installed, you will need to do the same thing on /etc/default/grub and then run update-grub.

  7. I've had much better results using the latest Linux kernel (5.1) - though not using Ubuntu - but this is probably the most practical solution.

    According to https://phoronix.com/scan.php?page=news_item&px=AMD-MP2-I2C-Linux-5.2

    5.2 will bring further stability for Ryzen.

  8. Add these parameters to the boot option:

    ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2

    Press E to modify the boot option when you are inside GRUB.

  9. Use the below solution and thank me later.

    None of the solution worked for me i am using Ryzen 5 3500U. I have every parameter combination, used rufus, uneetbootin etc etc.

    Working solution and simple one USE Fedora Media Writer to create bootable image (ubuntu 18.04.3) and it will work like charm.

    No need to edit the boot parameter etc etc.
