I build a new system with a Core i5-4570S CPU and I use the internal graphics card.
I can Install Ubuntu 13.04 without problem and everything seems to work fine, but during boot and when I turn the PC off I see some really strange colors on the screen, kind of blue and the colors seem to be moving.
Do I have to worry about this? Once I am in the Unity/Gnome Desktop this does not occur.
The card seem to be recognised:
00:02.0 VGA compatible controller: Intel Corporation Haswell Integrated Graphics Controller (rev 06)
I am using this kernel:
3.8.0-30-generic #44-Ubuntu SMP Thu Aug 22 20:52:24 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
The second problem just came up. I did an update today, there was a new kernel.
After this update the machine does not show the lightdm login screen, just a blinking cursor. When I do Ctrl+Alt+F2 and restart
lightdm it gives me the login screen.
What can I do? Do you need more info?
