Ubuntu-drivers allows installation of (nvidia-340) drivers, which are
broken/break things.
Allowing ( :-P ) ubuntu-drivers to install nvidia-340 results in no GUI on
reboot, only console available.
X does appear to be running, but only a black screen.
Kernel:
================
5.4.0-33.37-generic 5.4.34
CPU:
=================
processor : 3
vendor_id : AuthenticAMD
cpu family : 23
model : 17
model name : AMD Ryzen 3 2200G with Radeon Vega Graphics
stepping : 0
GPU:
==============================
01:00.0 VGA compatible controller: NVIDIA Corporation G96CGL [Quadro FX 580]
(rev a1)
0a:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Raven
Ridge [Radeon Vega Series / Radeon Vega Mobile Series] (rev c8)
Error:
================
"
root@XXXXX# ubuntu-drivers list
ERROR:root:No "nvidia-dkms-340" can be found.
nvidia-340
"
1) Expected action - running 'ubuntu-drivers' lists NO drivers being
available, as allowing drivers to be installed that the installer
seems(?) to know are broken/will break things, is illogical.
2) Improvements - I had access to terminal (Ctrl-Alt Fxxx).
Why is there not an 'uninstall' option for ubuntu-drivers?
"
root@XXX# ubuntu-drivers
Available commands:
list: Show all driver packages which apply to the current system.
list-oem: Show all OEM enablement packages which apply to this system
devices: Show all devices which need drivers, and which packages apply to
them.
install: Install drivers that are appropriate for your hardware.
debug: Print all available information and debug data about drivers.
"
Reproduction:
=======================
1) ubuntu-drivers list
2) which shows:
"
ERROR:root:No "nvidia-dkms-340" can be found.
nvidia-340
"
3) ubuntu-drivers install nvidia-340
4) Reboot ==> black screen, no login screen
Solved problem by reinstall (later research showed that " apt-get purge
*nvidia* " may have rolled-back changes, however
" ubuntu-drivers uninstall nvidia-340 " would be a LOT more user-friendly).
