do-release-upgrade
No errors. On boot, I get a nice graphical 17.10 splash screens, then a few minutes later:
[ OK ] Started GNOME Display Manager
but no graphics visible, <Ctrl><Alt><F7> does nothing.
I do have a backup of 17.04 but I'd rather get 17.10 working! Also I'm really trying to avoid a clean install, though I know this may be the "right thing to do"...
I have tried
sudo apt-get purge "nvidia*"
which I assume should now use nouveau. But exactly same occurs. So as per this bug report, I added the nomodeset boot parameter
linux /boot/bmlinuz-4.13.0-16-generic ... ro nomodeset quiet splash
But no change. There are no options to "Disable integrated graphics/GPU in your BIOS" in my BIOS. So then as per this answer I did
lspci |grep VGA
02:00.0 VGA compatible controller NVIDIA G96GL [Quadro FX 580]
03:00.0 VGA compatible controller NVIDIA G84 [GeForce 8600 GT]
ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:07.0/0000:03:00.0 ==
modalias : pci:v....
vendor : NVIDIA corporation
model : G84 [GeForce 8600 GT]
driver : nvidia-304 - distro non-free
driver : nvidia-340 - distro non-free recommended
driver : xserver-xorg-video-nouveau - distro fere builtin
sudo apt-get install nvidia-340
this seems to install fine, but exactly same problem. So, then I uncommented this line
cat /etc/gdm3/custom.conf
...
WaylandEnable=false
Again no video. Note that I have 2 Nvidia cards, but this hasn't caused any problems in the past, and the Ubuntu splash screen appears nicely on both cards.
As per this old thread I checked I have got
sudo apt list --installed |grep 'xorg-legacy'
xserver-xorg-legacy/arflu 2:1.19.5-0ubuntu2 amd64 [installed,automatic]
Anyone know how to fix this now? I am assuming this must be a graphics driver problem, but I have tried all combinations I can think of. At this point I don't mind whether I use nouveau or nvidia, with X or wayland...
