Title:
screen is garbled with 14.10 (was fine with 14.04)
Status in xorg package in Ubuntu:
New
Bug description:
On a iMac Alu 2010, when
1) upgrading from 14.04 desktop to 14.10 desktop
OR
2) installing 10.10 server (SSH package only)
the screen shows thin horizontal lines moving on a black background.
/etc/X11/xorg.conf is absent (using default config),
/var/log/Xorg.0.log doesn't show any error beside the lack of the
fglrx module. But I doubt it's relevant with the symptoms appearing on
the server install.
Here is the lspci of the iMac
