I updated my system to newest kernel 18.104.22.168, rebooted the pc...
It "hangs" with black screen and a single underscore blinking.
Numlock/capslock leds switch on when activated, so it isn't technically hanging but still no tty's are available and no X server.
Since I've spent 2-3hours searching the web and trying to fix the problem (with a live usb).
Grub menu doesn't show.
(before I had it with countdown=0 ie skip, but I changed it to 5 and added verbose to the kernel args).
Also by reading the logs I recal something related to gvfs permision error and thunar having a sigterm..
What I have tried doing: (chroot from live usb)
-install the earlier kernel (22.214.171.124) [as some ppl have reported a bug 4Gigs of ram + 64bit+126.96.36.199]
-downgrading nvidia driver 304.60.3->304.60.2 (just in case.... )
I've removed the following:
Some details about the system that might or might not be relevant:
64bit, running on i5 2500k, 8gigs ram, nvidia gtx 570.
Running Openbox + tint + gdm.
I still have no idea what happened to render the system incapable of booting...
So I need for some help figuring that out and how to solve the problem
If grub doesn't load, then it may not be the system, but the bootloader. Can you install grub (or whatever bootloader you please) onto a cd/usb and then boot the install from there?
Ok, now I feel stupid...
I was about to re-install grub to MBR and it occured to me to check the bios boot drive sequence.
My bios had switched the drive boot sequence for some reason
I had problems with it before showing a msg saying "F1 for configuration restore F2 for new config...etc"
But I never had it change boot device priority before.
Maybe it's a bad battery...
So all that work for nothing...
Thanks for the suggestion though it helped narrowing down the problem
Btw regarding the installation of grub/syslinux on usb :
Doesn't the LiveCD have a bootloader already?
I can see an entry of "boot existing os" and by the "Tab to edit line" I'm guessing its syslinux (never used it tbh).
If so what would a standard grub boot line translate to for syslinux ?
