I reinstalled my Ubuntu 20.04 (on dual boot with Win 10) and my sound, wifi adapter are not discovered. Also there seems to be a problem with integrated graphics (llvmpipe shows up in Settings>About instead of what I would expect to be an Intel integrated graphics; also there is no option to manage multiple monitors). I attempted the re-installation of Ubuntu already several times, and still get these symptoms.
Strangely, during the reinstalls from bootable USB, the graphics and wifi seemed to be working just fine, but once the installation is done, they are not discovered.
I turned-off secure boot in bios, I also turned off the fast boot in Windows.
Not sure how to approach this problem "holistically" (without having to find not working devices and fixing them one by one), and why this was happening. Any ideas?
I listed all devices with sudo lspci -v -k
but unsure what to look for there.
I also listed all devices with sudo lshw -sanitize
and have a lot of "UNCLAIMED" there - and I guess those would be the devices I have problems with.
lshw
and have a lot of "UNCLAIMED" there (?) looks like those may be the devices that are not working properly? – average.everyman Jul 08 '21 at 11:245.8.0-59-generic
