Installing Ubuntu 18.04.5 is imposibble but 20 i possible
I have new laptop Lenovo ideapad gaming 3 15arh05 with ryzen 7 4800H and Nvidia GTX 1650ti. For work I need to use Ubuntu 18 with Ros Melodic but I am unable to install this system, I tried Ubuntu 20 and it worked perfectly. I tried with diffrent options like secure boot, uefi/legacy. When I choose TRY UBUNTU, I get errors:
pci ... AMD-VI: Unable to read/write to IOMMU perf counter
integrity: Problem loading X.509 certificate -65
nouveau DRM: failed to create kernel channel, -22
sd [sda] No Caching mode page found
sd [sda] Assuming drive cache: write through
Then I see purple screen and get over 100 errors
[FAILED] Failed to start User Manager for UID 121.
[OK] Started Session c(numbers from 5 to 99) of user gdm.
[OK] Removed slice User Slice of gdm.
[OK] Created slice User Slice of gdm.
Then process freezes and I need to reboot laptop.
I have fought for 6 days. Maybe I don't see everything and I do mistake somewhere or should I install Ubuntu 20 and somehow try to install Ros Melodic?
Solution 1:
You're laptop is probably too new for the kernel provided with the setup of Ubuntu 18.04. The two simplest solution I see :
-
Use the ROS provided for ubuntu 20.04 http://wiki.ros.org/noetic/Installation
-
Install ubuntu 18.04 as a virtual machine with gnome-boxes or virtualbox
