After upgrade my desktop system (asrock z77, intel i5, geforce gtx 650, 16 GB ram) can only boot to a black screen. I mean after the GRUB interface (kernel is 3.8.8-19-generic) and purple screen.
I have attempted pretty much every work around listed that I have been able to locate on the forums and elsewhere, here are a couple of resources (if anyone else is having a similar issue):
How to set NOMODESET and other kernel boot options in grub2
I have modified grub entry several times in different ways. It tends to hang at this point with statement "Loading initial ramdisk ..."
Attempted to reinstall Ubuntu's system files following UbuntuReinstallation guide, but:
(i.) option to upgrade is not available; (ii.) install via manual partitioning (something-else) has issues, when I select the "sda1" partition and click install now I get an error message saying that "No root file system is defined".
**this error message occurs regardless of setting mount point as "/"
I then tried 'boot repair', thinking it might be something that could help: http://paste.ubuntu.com/5627802/
I am at the point that I am thinking the microsoft solution for serious BSOD was to take the box outside and shoot it or toss it off a bridge from a moving vehicle is the only viable option.
If anyone can help, make some suggestions - it would be greatly appreciated.
Thanks in advance.
Footnote: Sunday 10th May 2013
Over the last week, I have attempted multiple times to create a work around to this 'blank screen' issue. To the point I have built a second identical machine, two separate Nvidia graphics cards (GTX650 & GTS450) to play around on with fresh installs of 12.10 and 13.04
I have followed numerous suggestions from forum threads, bug reports and askubuntu posts:
Ubuntu 12.10 / 13.04
sudo apt-add-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-current nvidia-settings sudo apt-get install linux-headers-generic sudo apt-get --reinstall nvidia-current nvidia-settings sudo reboot
As well as:
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current nvidia-settings sudo apt-get install linux-headers-generic sudo apt-get --reinstall nvidia-current nvidia-settings sudo reboot
I have done the 'remove':
sudo apt-remove nvidia-current nvidia-common sudo apt-remove nvidia-current-updates
I have 'reconfigured':
sudo dpkg-reconfigure nvidia-current sudo dpkg-reconfigure nvidia-current-updates
I have purged the butthead drivers released by nvidia:
sudo apt-get purge nvidia*; sudo rm /etc/x11/xorg.conf
Installed new nvidia drivers (310, 319) following some of the above:
sudo apt-get install-experimental-319 sudo apt-get install-319-updates
Cleared Nouveau (as it was not being blacklisted):
sudo apt-get --purge remove xserver-xorg-video-nouveau sudo apt-get install linux-headers-'uname -r' sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current nvidia-settings sudo apt-get-alternatives --config gl_conf sudo ldconfig sudo update-initramfs -u sudo nvidia-xconfig
Redone Unity by installing 'dconf-tools'.
Original and test system both have nvidia graphics cards to which monitors are attached, however neither appear in 'additional drivers'. In the case of the test system, this is regardless of whether the card is in the PCI slot with fresh install or added later in both 12.10 and 13.04.
When I do: 'lsmod | grep -i nv' after install nvidia, the nvida data is there, but the system still boots into blank screen. I have played with 'lightdm' and 'nomodeset'.
In the case of editing grub to add 'nomodeset' in test system, this causes the system to hang after 'Loading initial ramdisk ...'
So, if anyone has some thoughts, I am all ears.
