I've updated my kernel from 4.18.16 to 4.19.1 but now the screen resolution is fixed to 1024x768 and Graphics in Settings>Details>About says I'm using llvmpipe (LLVM 6.0, 256 bits).
Also I've listed the modules loaded but there isn't nvidia driver.
How can I repair this issue? I've seen that also with kernel 4.19 other users had reported this issue.
Update: I've upgraded my distro to 18.10 and now if I remove the nvidia driver the system start and use the correct resolution (1920x1080). If I install the driver the system won't start and block at some point of the initialization such as Start Network Manager ecc and not reach login page.
