Hi, I’m having trouble getting Ubuntu install on my system. I am using an ati Radeon 5870 with 6 displayports. I have it connected via one of the displayports. When I tried to install via the usb, I get a black screen when I select either try Ubuntu or install. The monitor says out of sync, incorrect timing. My monitor is a dell u2718q. I can get it to install with options “ro nomodeset vga=791”. Once installed, I get the same black screen, monitor out of sync, incorrect timing. Also, I can’t see the grub menu, try pressing shift, etc. the display says no signal. Any help?
