elementary OS 0.3.2 Freya (64-bit) (Ubuntu 14.04) black screen after Update

Question

Hello I have a problem with ubuntu installed on my laptop.

The laptop is ASUS K501U with NVIDIA Corporation GM107M [GeForce GTX 950M] (rev a2). My System is elementary OS 0.3.2 Freya (64-bit).

The problem is after I installed updates to my system my graphic card drivers broke. When I turn on the computer I get black screen after selecting the system ( I have ubuntu and windows installed) I think that it is working because I can hear the login screen sound.

What I found was : https://askubuntu.com/questions/41681/blank-screen-after-installing-nvidia-restricted-driver

But it only displays the screen with 1024x764 resolution

I found that I can install other drivers from software updates. But selecting e.g nvidia 375.20, which is recommened for this graphic card breaks the display again ( black after rebooting ) and I have to repeat to process from the link above once again and use low resolution.

I also tried this link: https://askubuntu.com/questions/684181/asus-strix-gtx970-unable-to-get-1920x1080-resolution-ubuntu-14-04

But nothing changed, still black screen after reboot.

Please help :(

It may be due to kernel issues. Try to boot with an older kernel from grub menu as below.

• Select Advanced options for elementary os
• Select the kernel which u think is suitable

If that works, you can remove the new kernel while retaining the older one. But be sure to check which kernel u currently using by

uname -r

and try not mess with it.

To remove kernel, replace X.XX.X-XX with kernel version as below

sudo apt purge linux-image-X.XX.X-XX-generic linux-image-extra-X.XX.X-X-generic linux-headers-X.XX.X-XX linux-headers-X.XX.X-XX-generic

Then update the grub

sudo update-grub

Reboot ur system.
