Description fabio.bossi 2009-10-16 07:51:31 UTC
Screen goes black after booting an Ubuntu LiveCD on a system with a Radeon X1650 card and a Daewoo DLT-22W4T TV/Monitor, though splash screen is displayed correctly and I can still acces ttys. I have no problems if I replace the monitor with a different one.

I have already tried reverting to VESA with no effect. It seems like Xorg can't find the right monitor settings.

Here are significative parts of the output from lspci and of Xorg.0.log
