Questions[amd-ryzen](ubuntu)

I installed Ubuntu 20.04 on my Amd Ryzen 5 1600 / Nvidia Gtx 1070 two weeks ago but Ubuntu completely freezes from time to time.

Keyboard and screen stop working completely, mouse sometimes is able to keep moving. I've tried using the magic SysRq key but didn't work. Also tried alt+F1 but didn't get any response from the system either. Basically I'm left with pressing the power button in order to restart.

I'm suspecting Nvidia but I don't know how to verify.

nvidia-smi shows driver version 440.100.

Found these logs in /var/log/Xorg.1.log.old that showed the time around my computer crashed.

Short Version

On Ubuntu 20.04 cannot get internal and external monitor working at the same time. Can have internal only with default drivers OR external only with manually installed NVIDIA driver. Help!

My system is an ASUS TUF A15 Gaming laptop (FA506). It has an AMD® Ryzen™ 7 4800H Processor with integrated graphics and a NVIDIA RTX 2060.

• Fresh Ubuntu 20.04 Install
• Need to set nouveau.modeset=0 in grub entry to get graphics to work
• External displays not detected
• Ubuntu 20.04 does not show anything in the Additional Drivers dialog
• Installing nvidia-driver-440 and running nvidia-xconfig gets the nvidia card working but only the external display (displayport on usbc port) is detected, internal display is not working
• Can switch back to internal display only by deleting /etc/X11/xorg.conf and rebooting but then lose external displays and NVIDIA driver not being used
• Can switch back to NVIDIA by running nvidia-xconfig again and rebooting

Long Version

After a fresh Ubuntu 20.04 install (with installing proprietary software enabled) the laptop boots to back screen with the text

[    7.779369] ucsi_acpi USBC000:00: PPM init failed (-110)

I can log in by switching to a virtual terminal with ctrl + alt + F2. After I log in the screen is spammed for over a minute with message:

[   80.199703] nouveau 0000:01:00.0 fifo: SCHED_ERROR 08 []

Followed by

[   80.206302] nouveau 0000:01:00.0 DRM: failed to idle channel 0 [DRM]

After this I can access the terminal. Based on internet advice I can modify the linux grub entry by changing the a line of /etc/default/grub from:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.modeset=0"

and running

sudo update-grub

After reboot I get the gdm login screen and can log in to a graphical session but if I connect an external it is not detected. Output of xrandr with or without external monitors connect via DisplayPort-USBC and HDMI is

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected primary 1920x1080+0+0 0mm x 0mm
   1920x1080     77.00*

Nvidia drivers have not been installed so I first update the system with sudo apt update and sudo apt dist-upgrade and reboot. I check the Additional Drivers tab of Software & Updates but it says "No additional drivers available". Running ubuntu-drivers devices shows nothing.

Next best advice is to install the nvidia drivers through apt

sudo apt install nvidia-driver-440 

After reboot the monitor situation is unchanged still only internal montior. xrandr output is the same, but Nvidia driver is now installed. nvidia-smi shows:

nvidia-settings shows a small empty window. Launching is from the terminal prints:

ERROR: Unable to load info from any available system


(nvidia-settings:2986): GLib-GObject-CRITICAL **: 09:45:58.786: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** Message: 09:45:58.789: PRIME: No offloading required. Abort
** Message: 09:45:58.789: PRIME: is it supported? no

Now I run sudo nvidia-xconfig to generate /etc/X11/xorg.conf. After a reboot THE EXTERNAL MONITOR IS WORKING I get the normal gdm login screen on my external (displayport) monitor and can login to a graphical session yay. Sadly the internal monitor is no longer detected and just shows the ASUS logo. nvidia-settings dialog now has all the options I would expect (launching from terminal gives the same output as before)

As requested by kanehekili the output of xrandr -q is now:

PLEASE HELP ME FIGURE THIS OUT

From my internet searching I am not the only one battling with this AMD/NVIDIA hybrid graphics configuration. The holy grail would be seamless integration of the two graphics cards to save battery when possible and use dicrete graphics when needed but I will happily settle for permanent power guzzling nvidia with both monitors working!

From my research the core of the issue is that the nvidia card is hard wired to the displayport and the integrated graphics are connected to the internal montior. Ideally the nvidia can render to a buffer which can be copied to the integrated graphics but I don't know the specifics and don't know how to configure this.

Note: Some internet advice has recommended adding the nvidia ppa before installing nvidia drivers:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update

I have tried this in the past but there is no difference, the nvidia-driver-440 package in that ppa and the ubuntu repository are the same version 440.82+really.440.64-0ubuntu6 and there is no change to the Additional Drivers tab.

Also note: I have secure boot disabled

Edit: This post Ubuntu 20.04 does not recognize second monitor

Suggests installing nvidia-driver-435 but in my case this does not solve the issue.

I have a partial answer to my own question but would still like help.

After reading this reddit post I came to suspect that the kernel version in Ubuntu 20.04 which is 5.4 does not have good support for the latest AMD APUs. To test this I installed the latest kernel 5.6.15 using the instructions here. With the newer kernel installed I can now use my HDMI port for an external monitor while running on the integrated graphics. That is by deleting the xorg.conf sudo rm /etc/X11/xorg.conf and rebooting. But when using the nvidia card I can still only use the displayport (on usbc). I would still like to be able to use NVIDIA on the internal display.

I built a new computer and am now getting weird graphics glitches when browsing the web or streaming video in a browser.

My setup:

Ryzen 5 3400G processor with integrated graphics

Gigabyte B450M DS3H motherboard (BIOS is updated with latest firmware), 16GB (2x8GB) DDR4 3200

Connected to Samsung Q70R QLED Smart 4K TV (old computer and HDMI cable worked fine with this TV)

I have tried many of the fixes that I found searching online, but none of them seem to completely fix the problem. I have tried fresh installs of the latest Ubuntu 18.04 and 20.04 versions. I have tried a couple methods of updating or changing the kernel versions. Changing resolutions, refresh rates, or scaling does not fix the issue.

Current configuration after fresh 20.04 install:

I have Ryzen 5 3600, Gigabyte X570 GAMING X and Radeon RX 580 Series. I installed Ubuntu 20.04 and it is loaded with kernel parameter 'acpi=off' but now system recognize only 1 core(lspcu, cut /proc/cpuinfo, nproc). When I remove 'acpi=off' - Ubuntu freezes on login screen. dmidecode -t processor recognize all cores. Can I somehow fix this issue? Searched in internet and already tried a lot but nothing helped. If dmidecode do recognize all cores - is it possible to refresh cpu cores info for OS after system boot?

Thanks!!

I have MSI MPG X570 GAMING EDGE WIFI motherboard ( ), holding AMD Ryzen 3600X Processor.

I tried original kernel 4.15 on ubuntu 18.04 Bionic, and sensors-detect could not detect any sensors.

I also tried 5.1 kernel ("Linux 5.1.0-050100-generic") and updated lm-sensor could not detect any sensors on the MB or CPU.

What am I doing wrong? I need to be able to access the CPU temperature. Is there anyway else I could achieve the same?

Thank you, DP.
