I have tried installing Ubuntu 20.04 in dual boot with Windows 10 on my 5 years old Lenovo flex 2 Pro-15 laptop:
Intel Core i7-5500U (2,4 Ghz, 2 cores)
8 GB RAM - original
NVIDIA GeForce 840M 1GB + Intel HD Graphics 5500 1GB
disc upgraded to ADATA SU650 (960GB) SSD
I have installed Win10 without any issues. First installation of Ubuntu ended with an error message, but I was able to boot Ubuntu and log myself in. First thing I have noticed were missing icons of applications. When I tried to open terminal or Firefox (I did not try to open any other app), the whole system froze and then crashed after a few minutes.
I have reinstalled both systems (Windows 10 and Ubuntu), this time without an error message, Ubuntu looked fine, but it crashed again few minutes after I opened terminal.
I have tried opening virtual console and found out it is full of: ...Failed to write entry...Read-only filesystem
Updating firmware of SSD did not help. Next, I found solution including Kernel update, but I cannot access Firefox and it does not recognize any USB Flash-drive.
Is there any solution or should I just give up and keep only Win10 on my laptop?
