Today I think I've found a bug in the Radeon DRM driver as shipped with Fedora's 2.6.31.5 kernel (F12). This morning I needed to give a presentation which I had made on my main system (F11), however upon hooking up the projector to the laptop's VGA port I got intermittent screen flashing (projector) a blur of the secondary display very distorted (think similar to the "dream" Compiz Fusion effect) and the laptop couldn't produce an image on the projector. Upon reboot (with the projector still hooked up) I could see all other screens just fine: BIOS splash, GRUB, even the first line when loading the kernel BEFORE the DRM is loaded and KMS kicks in, because as soon as it does, the flashing/distorting cycle begins again.
I had to boot into Vista (which thankfully is loaded with OOo and I had my presentation on a backup USB key) to be able to conduct my lecture, but was left with a very nasty taste in my mouth after seeing that apparently the driver has some issues with external displays and this lapotop.
The hardware is:
Chipset AMD SB600 based, RS690M display adapter, AMD Turion TL-58 CPU, 2 Gigs of RAM.
Fedora 12 is running with all the most recent updates as of today, running the x86_64 version.
