I have been facing the terrible problem to get to my Ubuntu desktop. I posted several questions and got several suggestions. To keep the track let me write down all the process I have been through: To start with, I have a MSI gaming laptop: Intel(R) Core i7-6820HK CPU 2.7GHz, 16GB RAM, Windows 10, 64x, NVIDIA GeForce GTX 980M.
About two weeks ago I installed Ubuntu 16.04 as a dual-boot together with Win 10. The obstacles I had during the installation were:
There was a blank-purple screen: to solve it I set
nomodesetand went on...
There was no option "install Ubuntu alongside windows 10", I chose something else following the suggestions from this site...
It directed me to partition the disks. There was no windows loader in the box, but only some values such as:
free space 1 MB; /dev/sda1/ntfs with the 528345 MB 87947 MB used; /dev/sda2/ntfs with the 429495 MB 150 MB used; free space 1 MB; /dev/sda3 with the 21474 MB unknown; free space 0 MB; /dev/sda4 ntfs with the 20885 20100 MB used; free space 0 MB.
However, I had already partitioned two disk spaces (30GB and 400GB) in Windows using disk partitioning...
Then I deleted these two:
/dev/sda4 ntfs with the 20885 20100 MB used /dev/sda3 with the 21474 MB unknown
to free some space for SWAP, root and boot and home (Mount point). I assigned appropriate sizes for respective mount points, again followed advice from Ask Ubuntu here. They are as follows:
/dev/sda3 swap 2047 MB unknown /dev/sda4 ext4 /home 10240 MB unknown /dev/sda5 ext4 / 20479 MB unknown /dev/sda6 biosgrub 5 MB unknown
At that stage I confirmed from this forum that I could proceed with the installation.
After some time, I installed Cuda 8.0.44 and cuDNN v5.1 Library for Linux to learn Tensorflow with GPU support. To install Sublimetext I followed Youtube and I installed synaptic package manager and reloaded it as shown. The Reload failed. I thought rebooting might help and restarted the device, since then I couldn't log in to my desktop. I tried several ways to solve the issue such as this and this from Youtube
- there used to be a quick Nvidia window for, say, a millisecond when I switched it on. After installing Cuda 8.0.44 and cuDNN v5.1 that prompt disappeared; - The laptop functioned strangely, it got shut down with a strange crack noise since I had dual-booted it with Ubuntu.
- After trying several solutions given in the forums, I ended up installing Gnome as suggested here as Solution 3. After rebooting, the desktop changed to Ubuntu Gnome, but still didn't solve the loop problem. Then I went to BIOS and changed the boot priority to another option, didn't work, then again came back to previous priority and now I can't even access to that login screen. When I switch the computer on I have purple screen suggesting *Ubuntu, Advanced options for Ubuntu, and System setup. Once I hit Ubuntu it goes through some process: Then the screen gets dark for about 4 seconds and quickly shows up this: Then it goes immediately back to dark screen and again after about 4 seconds the latter screen is shown again. This repeats infinitely.
When I type something, I can see them written after
voodoo-GT80S 6QE login: but I can write ONLY AND ONLY when it is shown. If I use
Ctrl + alt + f1, I can type for a short time, then it gets dark again. When I hit the power off, it shows:
Starting WPA supplicant OK Started WPA supplicant.
Then it is switched off with strange noise- like a rupture.
To solve the problem I tried this, given as Run These Commands
1: $ sudo mount /dev/sda5 /mnt 2: $ for i in /sys /proc /run /dev; do sudo mount --bind "$i" "/mnt/$i"; done 3: $ sudo mount /dev/sda6 /mnt/boot/efi 5: $ sudo chroot /mnt 6: # grub-install /dev/sda 7: # update-grub 8: # exit 9: $ for i in /sys /proc /run /dev; do sudo umount "/mnt/$i"; done 10: $ sudo umount /mnt/boot/efi 11: $ exit
When I typed
sudo mount /dev/sda6 /mnt/boot/efi it is showing
mount: mount point /mnt/boot/efi doesn't exist
Please take into consideration that I am not able to directly write these code blocks to normal terminal because of flickering effect of the terminal. I am writing these things after forcing the terminal to show up every time by pressing
I would ask you professionals to look through the problem and give some advice what to do next to restore the Ubuntu!
Thank you for your time and patience!
