Hello, Some info: X.Org X Server 1.6.1 Release Date: 2009-4-14 Card: ATI Technologies Inc M56P [Radeon Mobility X1600 (R500)], EXA accel method, using git radeon driver. direct rendering: Yes. OpenGL renderer string: Mesa DRI R300 20060815 x86/MMX/SSE2 TCL. The problem is, X fails to start when "DynamicPM" or "ForceLowPowerMode" is on. X starts fine with ClockGating on, but when I specify any of the two I mentioned, it borks X; I just get a black screen and logs stop at those two options. I've dump fglrx but I do miss power management. Let me know if you need more information. Thanks! Jayan
This looks like a dup of bug 21208. Are you using the latest code from git? Make sure you have commit efa1476fc0765b53298624198137dc5cc71d37a8 or newer.
That ticket you mentioned indicates display corruption, I can't even get X to start. I am using the latest code which was compiled on 04/18.

Definitely not a duplicate. I have identical symptoms as of commit 88a9e98341d96e5e7f48b69aed597d1bada6313a Hardware is MacBook Pro Code2Duo, Radeon Mobility X1600 Running Ubunty Jaunty
Can you attach your xorg log from the failed start?

I've got Radeon Mobility X1600 on xorg-x11-drv-ati-6.13.0-0.11.20091119git437113124 on 32 bit Fedora 12. In xorg.conf I've got DynamicPM, ForceLowPowerMode and ClockGating set to "True". There is no problem with booting Fedora 12 into GNOME.
Created attachment 32664 [details] Log generated when bug occurs (blank screen, computer lockup), as requested Well, unfortunately I can confirm that as of today (1:6.12.99+git20100114.3d158716-0ubuntu0sarvatt~karmic from Xorg-edgers), the bug is still present on my hardware. Note that ClockGating actually works (as in: doesn't crash). However, enabling DynamicPM still causes the computer to lock-up. Here is the Xorg.0.log generated with latest version.
i have a macbook pro 2,2 and i'm still having these issues that are described. i believe the issue is something specific about macbooks, i suspect due to the efi firmware that is on them. KMS is also non-functional (for me at least), and i think these two issues are related. any help is much appreciated. thanks,

I don't think you are experiencing the same issue. Macs do not make the vbios available after boot when using EFI so you will need to use bootcamp for now. See bug 26891.

Does KMS work for you with bootcamp? UMS isn't really maintained anymore. It would be better to try and fix KMS than to mess with UMS.

X does work when KMS is used, however KMS itself does not work. there are no power management related entries in /sys/class/drm/card0/device/, and powertop still reports ~25W of battery usage (suggesting the card is not being managed). thanks,

Most likely the apple vbios does not provide power tables (this is probably also why UMS options like DynamicPM don't work). Attach a copy of your vbios and I can take a look. There's not much you can besides hacking the driver to manually change the clocks. (as root) (use lspci to get the bus id) cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/vbios.rom echo 0 > rom
Created attachment 58202 [details] bios dump of apple radeon X1600 mobility cheers for taking a look at this for me. as far as manually hacking in clock values, where exactly should i start? thanks,
