Ubuntu doesn't recognize the hardware of Vivobook pro

Question

I have an ASUS Vivobook Pro, i7-7700HQ, NVidia GTX1050. I successfully installed Ubuntu 16.04LTS but I have some issues that I can't solve, I think they're related to the HW.

First, I have to run with acpi=off or it hangs during boot. This solves the boot but at shut down it hangs at the end of the process (I'm not the only one with this problem, I haven't found any working solution).

Secondly, this is the output of lscpu

The model name is correct, but I should have 4 cores, 2 threads per core (see https://ark.intel.com/products/97185/Intel-Core-i7-7700HQ-Processor-6M-Cache-up-to-3_80-GHz). System monitor shows only one cpu and I have some issues with 100% CPU sometimes.

Secondly, I have some flickering problem during windows resizing, but the glxinfo | grep direct reports that the direct rendering is activated. However, the output of lspci | grep VGA is the following

00:02.0 VGA compatible controller: Intel Corporation Device 591b (rev 04)

and also glxinfo | grep -i vendor reports

server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
    Vendor: Intel Open Source Technology Center (0x8086)
OpenGL vendor string: Intel Open Source Technology Center

So it seems to me that It does not recognize the NVidia GTX1050 and it uses the Intel chip.

Moreover, the touchpad is not recognized (again, common problem between ASUS users).

Could someone help me in order to check if there is something wrong with my installation? Are they related in some way? Or should I ask for a solution for each of the problem? PS Windows is running correctly. Thanks in advance!

Answer 1

I think that I've found a solution. I was booting with the "acpi=off" option. Removing that option (actually, I don't remember why I set that option, It was due to some compatibility issue that now the upgrade solved somehow) I can see all my CPU cores and my GPU! Hence, I suggest to upgrade and disable acpi=off in case of similar problems. Moreover, now the touchpad is working, no flickering during window resizing, and the system does not hang no more on shut down, although now the shutdown slowed down a bit.
