Hello, all. I am trying to make dual-head environment on Mac Pro with Ubuntu 10.10. My Mac Pro has the Radeon HD 2600 XT graphic card, so I decided to use the radeon driver.
Now, I connect two monitors (the same SAMSUNG monitors) and boot the system and X, one display works well, but the other is not recognized. In dmesg, I found out the following error message. I googled the message and found <http://www.mail-archive.com/[email protected]/msg16768.html> and <https://bugs.freedesktop.org/show_bug.cgi?id=29255>. Referring to these posts, I upgraded the kernel to 2.6.36 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-maverick/) and also graphic drivers (https://launchpad.net/~xorg-edgers/+archive/ppa). However, the same error is displayed. I am sorry to say that I have no idea how to use Alex's patch to `radeon_atombios.c' because of my poor knowledge of Linux. Is not this change included in the recent kernel or drivers? Because dual-head environment works successfully on Mac, I suspect the monitor or graphic card has no problem. The following is some display-related information and settings. I tried to attach video bios data, but I could not, because echo and cut are permission denied (of course, I did them as root). Thank you. $ dmesg | grep drm [ 11.044447] [drm] Initialized drm 1.1.0 20060810 [ 11.490963] [drm] radeon kernel modesetting enabled.
