Title:
[Lenovo laptop] Fail to completely boot with kernel 4.15.0-32-generic
Status in linux package in Ubuntu:
Invalid
Bug description:
Hi, my girlfriend was told yesterday it was time to upgrade from 16.04
to 18.04. Her computer is a Lenovo Ideapad 700-17ISK 80RV (Core i7
6700HQ with 16 GB RAM, a NVIDIA GeForce 940M embedded graphic card and
a Samsung SSD 830).
The upgrade process ran fluently but the disaster came after : the
laptop is unable to complete boot process. There is no more graphical
login screen. I searched a bit and found various tips, mainly
recommanding to disable Wayland
(https://www.reddit.com/r/Ubuntu/comments/8fu6oq/1804_is_not_booting_up_its_stuck_in_splash_screen/)
but it does not work for me.
I tried the recovery mode, and I can confirm that using directly the
resume option conveniently leads to a graphical login screen. Odd
thing : I have twice the recovery menu (and I need to validate twice
the resume entry to complete the startup process).
I also tried other kernels (4.15.0-30, -29, -24 and -23 versions),
that fluently leads to the graphical login screen, but completely
lacks basic modules for networking (no r8169 nor iwlmvm modules, thus
making the computer completely unusable).
There are also other problems, which are perhaps not related to the Linux
kernel / package. For example :
- the keyboard shortcuts for adjusting brightness are not functional with any
of the kernel I tried, 4.15.0-32-generic included ;
- there is no simple way to suspend the computer (no option directly
reachable - ergonomic fail - and closing the screen only make the screen black)
and when configuring the power button action to suspend the computer, there is
no way to recover (the screen remains black - no more pm-suspend command
available but systemctl suspend ends the same way). A hard poweroff is needed
(several seconds pressing the poweroff button).
Here is the output of the lspci command :

Please help, this is a very unfriendly situation, and very surprising
with a computer not so old and with no bleeding edge components.
Thanks in advance & best regards,
Al.
