Ubuntu 13.10 freezing and low graphics mode

Asked by Pawlo Shunkow

I have installed Ubuntu 13.10 64-bit on my desktop PC, and it seems it's not working properly. I have freezing while typing, the virtual console is not available, if I try go to it my screen is freezing, also the cursor leaves a trace on the screen.

I have tried to install Nvidia graphics drivers (from offsite, and from xorg repositories), but after it my Ubuntu doesn't boot. I see only a white blinking underline character cursor in top left corner of a black screen and nothing more. In that case I have to do a hard reboot, because the screen is frozen and I can't make my system respond in any other way.

I also tried to install Ubuntu 12.04, but the loader gives a message about "low graphics mode" and after that I see only a black screen, and I can do nothing.

For the moment I have reinstalled Ubuntu 13.10, and I am looking for an answer.

Can someone help me?

Specifications of my PC:
⠀CPU: Intel Core i5-4670K (Haswell)
⠀Motherboard: GigaByte G1.Sniper B5
⠀Graphics card: Asus GTX760-DC2OC-2GD5

Your CPU has an Intel GPU in it so you will need to install Bumblebee to get some sort of support for the Optimus mess

I have installed Bumblebee, I followed this https://wiki.ubuntu.com/Bumblebee#Installation.

sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get install bumblebee bumblebee-nvidia primus linux-headers-generic
Reboot

For the moment I have a white blinking underline character cursor in top left corner of a black screen and nothing more, again that same ((. I can hear "welcome" sound, but I cant see screen.
Do you have another ideas ?

I still have access to OS by recovery mode, I can provide you all necessary log files and etc.

Thank you.

On ubuntu forum I got such answer: "For me the solution will be, to change the motherboard, because my new Gigabyte motherboard does not work after installing the grafic-drivers. Gigabyte told me, that they do not support Linux.". Is it true ? Does the problem related to my motherboard ? There is no solution for me except of change motherboard ?

I have solved the problem by myself. I have installed ubuntu in UEFI mode, not in BIOS. This solution works fine for me.
