[Bug 305301] Re: [RC410] Xpress 200M hangs when resuming from suspend with DRI

** Description changed:

  Binary package hint: xserver-xorg-video-radeon
  
  Since I upgraded to 8.10 from 8.04 the machine does not resume from suspend. 
  1) Depending on the tools it behaves the following way: when using usual (gnome) suspend, when trying to resume it turns on and off with a blank screen. When using pm-utils, it turns on but the screen is blank. In all of these cases, the system is irresponsive and requires a hard reboot (held down power button). Sometimes the system just restarts (reboots) on its own after one attempt. 
  2) There is also one more problem with the X that is conected. Occasionally, when booting the system before getting the login window the system hangs with the blank screen. It also remains totally irresponsive with no Magic Keys working.
  
  The reason why I think  the issue is related to "radeon" driver is the following. I've had a lot of problems be with the ATI/AMD proprietary fglrx driver  (no dual head support, no xvid etc). However, when I upgraded to 8.10 I found the fglrx in use. Again, the performance was not good either (bad xv support and slow). But I could resume from suspend OK and do not remember any crashes when booting. I removed it and started using "radeon" driver. The performance was better, but I started experiencing the above-mentioned problems. I also tried "ati" driver (not sure if there is difference ) bu with no avail. 
  Someone found a similar bug a couple months ago and followed the suggested change in the Xorg.conf by trying different values for Option "AGPMode". it didn't work. I also tried hibernate tools. It did similar things.  I tried with/without  compiz, gives the same problem, as well as with the generic Xorg.conf file. I attach both below
  My laptop is Toshiba Satellite l35 with ATI Technologies Inc RC410 [Radeon Xpress 200M].
  
  $uname -a

  I am attaching some useful files below.
  Thanks very much in advance for your help!
