My computer boots to a black screen, what options do I have to fix it?
I have used wubi.exe to install Ubuntu 11.10 from Windows7.
The OS boots properly most of the time but fails sometimes and hits a blank screen. I could not check any messages on other terminals using "ctrl+alt+F1" as i feel like everything is froze... No keyboard input works.
After searching for sometime, it seems to be a known issue while using Ubuntu with a machine having discrete graphics.
The machines do contain integrated as well as discrete graphics card ATI Radeon 6xxxx
I installed the proprietary driver for ATI using Ubuntu software center but things gone worse. The OS boots and shows up with a black screen all the time. Using recovery mode, I uninstalled the fglrx driver and it healed.
Now I let the OS to boot with open source RADEON driver but the blank screen issue occurs at times and freezes.
Tried blacklisting radeon and fglrx in modprobe.d/blacklist.conf file. Rebooting with this didnt solved the problem. Again blank screen. Another reboot, no problem seen, and after few reboots, it again shows up with the problem.
Only solution I had was to set nomodeset while booting in the grub entry option. But the screen resolution is not good.
Any help is much appreciated.
