i upgraded my computer from 13.10 to 14.04, now my screen goes black after booting, but i can access tty1.
after a little experimenting, i tried using start x
it gave me this error (from /var/log/Xorg.0.log
).
i have tried :
- Can't install ATI proprietary drivers in 12.10
- What is the correct way to install proprietary ATI Catalyst Video Drivers (fglrx) directly from AMD?
- ATI Driver issue, fglrxinfo returning null display error, Xorg.conf file looks funky
- My computer boots to a black screen, what options do I have to fix it?
also fglrxinfo
gave me this Error: unable to open display (null)
and all of them still gave me the same result, what option left that i have ? what should i do and is there a step that i miss ?
thank you

First of all what is the model of you graphic card ? It can be found using this command:
I faced the same kind of issue recently. I had a Ubuntu 13.10 with a Radeon HD 3850 using fglrx-legacy drivers, and I was forced to remove them in order to upgrade to Ubuntu 14.04. The 14.04 generic display driver is ok but only provides a software rendering mode. I confirm that the standard fglrx drivers won't work (black screen) with old ATI cards such as the HD2xxx-4xxx series.
Once the 14.04 installed you can try to install fglrx-legacy drivers with those commands (worked for me on 13.04+, not tested yet on 14.04) or via Synaptic:

You can test if the drivers are properly working by using the following command
Video drivers are always the painful part. I am also interested. Please keep us informed if you manage to solve your problem !
