Now this is interesting!
As part Ubuntu updates the kernel was updated on 23rd April 2018 to
4.13.0-39-generic #44~16.04.1-Ubuntu SMP Thu Apr 5 16:43:10 UTC 2018 x86_64
x86_64 x86_64 GNU/Linux
On 3 consecutive occasions no the laptop has booted fine!
I decided to look around /ver/log and noticed this for the first time
-rw-r--r-- 1 root root 1929 Apr 24 09:04 gpu-manager.log and I now attach it
for anyone to see.
If you look at this log you will see that it provides many negative
answers to questions regarding which graphics card is present. But this
small extract here shows that it eventually found "/dev/dri/card0".
Vendor/Device Id: 8086:46
BusID "PCI:0@0:2:0"
Is boot vga? yes
Skipping , driven by "i915"
Skipping "/dev/dri/card0", driven by "i915"
Skipping "/dev/dri/card0", driven by "i915"
Found "/dev/dri/card0", driven by "i915"
output 0:
card0-LVDS-1
Number of connected outputs for /dev/dri/card0: 1
Does it require offloading? yes
last cards number = 1
If you recall, this bug was reporting that card could not be found and
was therefore booting into low graphics mode.
So, is my system fixed? Has the new kernel fixed it?
