[Bug 16873] Re: system freeze when using ati radeon 7000 with xorg "ati" driver

[Binh Trinh]

please try  a combination of those lines

Option  "DynamicClocks" "true"
Option  "AccelMethod"   "EXA"
Option  "DMAForXv"  "off"
Option  "BusType"   "AGP"
Option  "SubPixelOrder" "NONE"


worked for mine (Dell with ATI M6 running 1400x1050 @ 24bpp).
(don't know which line solved the freeze though :)

[Bug 47775] Re: [dapper] xrandr freezes the system (radeon, MergedFB)

[Binh Trinh]

I've found a solution for the ATI lockups...
Hopefully, you guys will be able to independently confirm it.

I've got a Dell with ATI M6 running edgy with xserver-xorg-video-ati
6.6.2-0ubuntu1.  The stock xorg.conf causes fast frequent random lockups
at 24 bpp and somehow less frequent random lockups at 16bpp.

I don't know how, but inserting these lines (all or some of them) to the stock 
xorg.conf solves the freezes (in Section "Device"):  
Option "DynamicClocks"  "true"
Option "AccelMethod" "EXA"
Option  "DMAForXv" "off"
Option "SubPixelOrder" "None"
Option  "BusType" "AGP"

My hunch tells me that the important line is either the DynamicClocks or
the AccelMethod.

Note:  I have no idea of stability in 3D.  But in 2D, it is quite stable
(uptime 2+ days now); and much faster than Option "NoAccel" or Driver
"vesa".

Please try and spread the word.
