RESOLVED: Nvidia Card install issues LinuxMint 13 KDE 64BIT

Post by exup »

Hi

I have been trying to install Linux Mint for a couple of weeks now.
The live CD works fine in compatability mode. If I dont select compatability then I get a white screen and no progress from there.
After installing in compatability mode and rebooting I dont even see the grub menu, I just get a garbled screen of pixels.

I have bypassed the video card (Nvidia GTX550 Ti) in the BIOS and using the gigabyte onboard graphics. (See signature for specs of the machine)
I then see grub menu and if I then click the default linux mint I am getting nouveau unkown port errors.

I have seen a few entries for this issue the first mention to uninstall the Ubiquity slide show mint at installl unders software manager. But when I check this is not installed anyway? Second troubleshooting points to updating the grub menu. But my Linux skills are not to good and I cannot seem to complete this. This what I have done.

using the live CD to get back into Linux mint.

mount the drive first
mount /dev/sda1 /mnt

following tips about editing files from live CD I ran this

mount --bind /dev /mnt/dev

Edit the /mnt/etc/default/gurb file and change the following

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to be ="quiet splash nouveau.noaccel=1 nomodeset"

I save the file ok
then run update-grub but see the error /usr/sbin/grub-probe: error: cannot find device for / (is/dev mounted)

I suspect the way I have mounted the drive is wrong?

Hi

I found a few sites that mentioned the /dev not mounted issue. But they simply said "I used the CHROOT method" but I did not know what this was. Finally found out what the extra steps are. The steps are copied from this site minus the re-install of Grub parts. https://help.ubuntu.com/community/Grub2 ... via_ChRoot

So starting from the begining and booting off the live CD

Determine your normal system partition. The following commands may be helpful. The fdisk switch is a lowercase "L".

Code: Select all

   sudo fdisk -l
   sudo blkid
   df -Th
Mount your normal system partition. X is the drive letter. Y is the partition number:
Substitute the correct partition: sda1, sdb5, etc.

Code: Select all

sudo mount /dev/sdXY /mnt1.
Example 1: sudo mount /dev/sda1 /mnt
Example 2: sudo mount /dev/md1 /mnt

Only if you have a separate boot partition (where sdYY is the /boot partition designation) or skip this which is what I did

Code: Select all

sudo mount /dev/sdYY /mnt/boot1
Example 1: sudo mount /dev/sdb6 /mnt/boot
Example 2: sudo mount /dev/md0 /mnt/boot

Edit your /etc/default/grub file to have the nomodeset as shown earlier in this post. Try that first and if that does not work add the extra nouveau.noaccel=1 then save it.

Mount the critical virtual filesystems. Run the following as a single command:

Code: Select all

  for i in /dev /dev/pts /proc /sys /run; do sudo    mount -B $i /mnt$i; done
Chroot into your normal system device:

Code: Select all

sudo chroot /mnt
   update-grub
   reboot
and it works on reboot!
