I am trying to install Linux on Lenovo Ideapad Z575 (AMD). When I run Ubuntu or Fedora from a LiveCD, I got some initial screens (purple screen with small icon for Ubuntu, some information screen from Fedora), and then.... nothing. For Ubuntu, I have a black screen, although I hear the Ubuntish sound when the login screen appears. So it is there, but the display does not work.

Any ideas how to make the display working?

  • What video hardware does it have? – Keith Apr 02 '12 at 14:35
  • Integrated Radeon. The processor is AMD A6-3400 APU – Jakub M. Apr 02 '12 at 16:41
  • Ah. There are two open-source drivers for that one, and there is the closed-source one. Which driver are you using? I recommend the open-source drivers for general use. – Keith Apr 02 '12 at 22:48
  • Frankly, I was running (unsuccessfully) Linux from LiveCD, so I run all the defaults. I didn't reach point of driver selection – Jakub M. Apr 03 '12 at 06:05
  • I managed to install crunchbang Linux, and then install the ATI drivers. so I can proceed. But the issue is still opened, for those that want Ubuntu or Fedora. – Jakub M. Apr 05 '12 at 07:10
  • I have Lenovo Ideapad Z575 too. Same problem U describe, but I tried GParted (Live USB). System started, splash screen was OK, then some txt messages and - suddenly - everything disappears and screen turned off. No response, no alert messages. Simply - black hole ;-) Can I do something BEFORE starting Live USB linux? –  Apr 29 '12 at 14:19

I solved it by adding nomodeset and xforcevesa in grub options, so the system do not "turn black" after booting, and is running with the generic drivers. Then after launching the system, I installed official drivers from ATI and now all is fine.

If i have this problem, I press ctrl alt F1, wich gives me the commandline screen. And then without typing anything else, I press ctrl+alt+F7, and after a couple of seconds the screen seems to reset, and I can login again. (PS: On my keyboard I have to press ctrl, then alt, then first the orange Fn key and thén the F7 key!)
