Bug reported by Zack Weinberg on the Debian BTS 2 weeks ago, discussed with airlied on IRC a couple times. Since 6.6.192 and kernel 2.6.22, the radeon driver enables DRI on PCI:*(1:5:0) ATI Technologies Inc RC410 [Radeon Xpress 200M] rev 0 It results in a black screen for Zack. The log with 6.6.193 and DRI is available at: http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=42;filename=xorg.log.6_6_193-1_dri;att=6;bug=437321 With DRI disabled in xorg.conf: http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=42;filename=xorg.log.6_6_193-1_no-dri;att=5;bug=437321 With AIGLX disabled (requested by airlied): http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=52;filename=xorg.log.6_6_193-1_no-aiglx;att=1;bug=437321 And finally, airlied requested the dmesg output when debug is enabled in the drm kernel module: http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=62;bug=437321 I am marking as a blocker for 6.7 in case it's easy to fix. But, this "regression" may be easily worked around by disabling DRI, feel free to unblock if there's too much work needed to fix this...
I also have the exact same symptoms: 01:05.0 VGA compatible controller: ATI Technologies Inc RC410 [Radeon Xpress 200] (prog-if 00 [VGA]) Subsystem: Intel Corporation Unknown device d600 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 21 Memory at d8000000 (32-bit, prefetchable) [size=128M] I/O ports at ee00 [size=256] Memory at fdef0000 (32-bit, non-prefetchable) [size=64K] [virtual] Expansion ROM at fde00000 [disabled] [size=128K] Capabilities: <access denied> Testing on Fedora Core 7, all packages updated as of 2007-09-20. All gits mentioned updated as of 2007-09-20. Compiled libdrm and mesa from git and put symlinks (after backing up original files), and also compiled current git for xf86-video-ati . On startup, screen blanks out (LED on monitor turns from green to amber, like a powersaving mode). Keyboard does not respond to Ctrl-Alt-Backspace. Machine is still responsive, since I can ssh from another location and kill X. At least X can return to text mode on kill.
I suspect we need to make adjustments to the memory controller when the DRI is enabled. Hopefully we'll get some info from AMD soon.
From https://bugs.launchpad.net/bugs/139241 (and duplicates) it seems like the [1002:5975] card has to have DRI disabled as well.

Created attachment 11910 [details] [review] rename to PCI_CHIP_RS485_5975 everywhere Ok, I mean RS485 cards. They are just called RS482_5975 in the code. Since bugzilla refuses me to open a new bug for that, I'll attach a patch for renaming it to RS485_5975 here. The other patch has to corrected accordingly.

I'm seeing this on suse 10.3 with xorg 7.2.

But, I can still ssh to the laptop...
With fglrx driver 8.42.3 the ATI Technologies Inc RC410 [Radeon Xpress 200] integrated chip in my machine works correctly with DRI enabled (but only at 1280x1024, and the screen is capable of at least 1400x1050). Is there anything I can do on my machine that will provide information on how to enable DRI correctly on the open-source driver?
Created attachment 12671 [details] Result of running revenge-1.0 on Radeon XPRESS 200M This is the result of running revenge 1.0 on my machine: ATI Technologies Inc RC410 [Radeon Xpress 200]. Beryl is running but with metacity as window manager.
The DRI should work on that chip now.
