Don't panic - that's how it is designed. It is very good except on those few occasions it fails - when it is a pita. In most cases you need only repopulate the xorg.conf as little as you need).How are you getting all these logs?

note: usb kbd+mouse are handled through the usbhid driver. Unless you have a very unusual setup...IIRC: you can also get this error if you have not cleaned up after the fglrx un-install.

Your chipset is RV610/630 (please confirm with lspci | grep ATI).

i.e. do not expect 3D accel with the radeon driver.

2600XT is supported by the RadeonHD driver.

It is possible that Adam has ruled these out as possible causes of your problems.

3D acceleration is supported by radeon. The man page is out-of-date. I would not recommend radeonhd as it sees very little development and even user support.

Yep - it is likely that radeonHD will get merged with radeon - much of why it exists is no longer relevant.

Still - the features page lists 3D element support as "mostly" for R600. Though the DRI wiki just mentions "many shaders missing". RadeonHD features reflect a more Cathedral-style development: stuff is either done or not started.

I dunno - I just have a hard time with the kernel preempting mode affecting the loading of modules in this way... but apparently it does. This prompts me to look in different directions JIC.

I also suspect that recompiling the kernel will be easier than downgrading - and I expect there will be an official kernel update for -current soon.

Normally I don't see trouble with the fglrx packages, just the ati installer and that unusual. But: I have had three of these just this week, all newly unsupported, and for some reason each one has ended up needing large chunks of X removed and installed before the free drivers could work. (None this card, and none slackware.) Where I have been able to preempt the, usually blind, proprietary package install, there has been no problem: it just goes.
