I've been trying to get dual monitors to work on my Squeeze system.
Originally I was using both the onboard video and an additional video
card. Now I have two monitors hooked up to the same video card (thanks
to a cheap craigslist purchase).
When I begin booting, both monitors give me a display. But when the
boot process gets to the point where text display changes (framebuffer
turning on?) one monitor goes blank and I cannot get it working again,
even when logged into a GUI.
Both monitors work properly with Knoppix 6.4.4. I tried using the
Knoppix xorg.conf, but that did not work. Here are some differences
between Squeeze and Knoppix:
Squeeze Knoppix
kernel: 2.6.32-5 2.6.37
xserver-xorg-video-radeon: 1:6.13.1-2 1:6.13.2-1
libdrm-radeon1: 2.4.23-0.0 2.4.23-1
radeontool: none 1.6.1-1
I don't know if the above differences are important or not.
Any ideas why one monitor always goes blank in Squeeze?
