I know that there a lot of threads regarding this issue. But I haven't found a solution for my problem.
First, My laptop is a:
lenovo u550 Intel cpu su 7300. 4gb ram. Graphic card is Ati Radeon hd 4330 switchable card with 512 mb
I have installed ubuntu 12.04 64 bit standard installation. I wanted to use my HDMI connection to my living room Tv, but there was no connection.
Here are the solutions I have tried:
updating Ubuntu repository, going to additional drivers and installing the rebooted my computer, navigated to the amd config app, got an error: saying that there is no graphic card.
followed this guide What is the correct way to install ATI Catalyst Video Drivers (fglrx)?
the installation was ok, but when i rebooted i got an error like in this thread :
I tried doing all the solutions mentioned in the comments, no luck :( every time I boot my computer it goes straight to tty1 screen. Tried using startx but i get a server error. I reinstalled the desktop using
apt-get install --reinstall ubuntu-desktop, no luck ...
as a last resort, and for taking pics of the process and errors I formatted my hard drive and installed Ubuntu all over. this time after the installation the os didn't work at all, just got a blank page with _. checked the boot records and it was OK, also the Ubuntu disk installation was out.
at the moment I'm using a win trail version. hoping to get some help, I don't want to go back to windows, but if I'm not able to fix this problem with my graphic card I will need to. My main use of my laptop is personal web use and as a living room computer, I connect it with a HDMI connection to my TV so this last function is crucial.
