[Bug 509273] Re: [Lucid] KMS doesn't work properly with ATI X200M

  Thread Previous • Date Previous • • Thread Next 
I've got the syslog with a persistent USB daily image. It says the
problem is in the kernel DRM.

** Description changed:

  Ubuntu 2010.02.17. daily build
  01:05.0 VGA compatible controller: ATI Technologies Inc RC410 [Radeon Xpress 200M]
  xserver-xorg-video-ati 1:6.12.99+git20100126.e5933fd7-0ubuntu1
  
  Normal boot:
  
  The desktop shows up for ~15 seconds (during this time everything works)
  then I get black screen with backlight and nothing works (pressing
  CTRL+ALT+F1 has no effect) + the CPU is working hard because the cooler
  runs faster. Hard reset is necessary.
  
  If I go into CLI with CTRL+ALT+F1 within the 15 seconds the computer works fine and it doesn't freezes (I have waited 10 minutes in CLI mode)
  ,but then if I try to change back to the GUI with CTRL+ALT+F7 I get black screen again with blacklight and CTRL+ALT+F1 doesn't work anymore so the only thing that works is hard reset again.
  
  nomodeset boot:
  Everything is perfect (compiz,flash,3d).

** Description changed:

  Ubuntu 2010.02.17. daily build
  01:05.0 VGA compatible controller: ATI Technologies Inc RC410 [Radeon Xpress 200M]
  xserver-xorg-video-ati 1:6.12.99+git20100126.e5933fd7-0ubuntu1
  
  Normal boot:
  
  The desktop shows up for ~15 seconds (during this time everything works)
  then I get black screen with backlight and nothing works (pressing
  CTRL+ALT+F1 has no effect) + the CPU is working hard because the cooler
  runs faster. Hard reset is necessary.
  
  If I go into CLI with CTRL+ALT+F1 within the 15 seconds the computer works fine and it doesn't freezes (I have waited 10 minutes in CLI mode)
  ,but then if I try to change back to the GUI with CTRL+ALT+F7 I get black screen again with blacklight and CTRL+ALT+F1 doesn't work anymore so the only thing that works is hard reset again.
  
  nomodeset boot:
  Everything is perfect (compiz,flash,3d).

** Description changed:

  Ubuntu 2010.02.17. daily build
  01:05.0 VGA compatible controller: ATI Technologies Inc RC410 [Radeon Xpress 200M]
  xserver-xorg-video-ati 1:6.12.99+git20100126.e5933fd7-0ubuntu1
  
  Normal boot:
- 
- The desktop shows up for ~15 seconds (during this time everything works)
- then I get black screen with backlight and nothing works (pressing
- CTRL+ALT+F1 has no effect) + the CPU is working hard because the cooler
- runs faster. Hard reset is necessary.
- 
+ The desktop shows up for ~15 seconds (during this time everything works) then I get black screen with backlight and nothing works (pressing CTRL+ALT+F1 has no effect) + the CPU is working hard because the cooler runs faster. Hard reset is necessary.
  If I go into CLI with CTRL+ALT+F1 within the 15 seconds the computer works fine and it doesn't freezes (I have waited 10 minutes in CLI mode)
  ,but then if I try to change back to the GUI with CTRL+ALT+F7 I get black screen again with blacklight and CTRL+ALT+F1 doesn't work anymore so the only thing that works is hard reset again.
  
  nomodeset boot:
  Everything is perfect (compiz,flash,3d).

  Normal boot:
  The desktop shows up for ~15 seconds (during this time everything works) then I get black screen with backlight and nothing works (pressing CTRL+ALT+F1 has no effect) + the CPU is working hard because the cooler runs faster. Hard reset is necessary.
  If I go into CLI with CTRL+ALT+F1 within the 15 seconds the computer works fine and it doesn't freezes (I have waited 10 minutes in CLI mode)
  ,but then if I try to change back to the GUI with CTRL+ALT+F7 I get black screen again with blacklight and CTRL+ALT+F1 doesn't work anymore so the only thing that works is hard reset again.
  
  nomodeset boot:
  Everything is perfect (compiz,flash,3d).
