Hi, I have got a similar problem and have tried solutions both in this post and some other related posts. Unfortunately, my problem is not solved.
My laptop has a Win10-Ubuntu 18.04 dual system. It has got an Intel integrated graphics card and a Quadro T2000. The default graphics, since installation of Ubuntu, is llvmpipe (“system setting”->“details”->“about”). I later installed 440.82 driver via Software & Updates. However, the system still uses llvmpipe. Rebooting the system does not help.
Following are some console outputs.

Some additional info:
-
I have removed /etc/X11/xorg.conf, since with this file, the login freezes after installing the Nvidia driver.
-
I have disabled secure boot. also disabled nouveau (“lsmod |grep nouveau” now gives no output).
-
Running “cat /etc/X11/default-display-manager” gives “/usr/sbin/gdm3”
Can anyone give some hints on what could be the problem? Thanks!
