[Bug 370953] Re: Memory allocation problem with virtual resolution

[strav]

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  Ubuntu 9.04, latest updates applied.
  Video Card: Intel Corporation Mobile 945GME Express Memory Controller Hub (rev 03)
  eee-pc 1000 (sd)
  
  Let me first say that perhaps this is a configuration problem on my side
  - my apologies if it's the case. Anyhow, when trying to set a virtual
- resolution of 2704 x 1050 for using both my laptop's screen and my
- external LCD screen, xorg loads correctly however, if I try to play a
- video in either VLC or Kaffeine (on either screens), each application
- segfault with, for VLC, the following error message
+ resolution of 2704 x 1050 ((1680 + 1024) x 1050 ) for using both my
+ laptop's screen and my external LCD screen, xorg loads correctly
+ however, if I try to play a video in either VLC or Kaffeine (on either
+ screens), each application segfault with, for VLC, the following error
+ message:
  
+ [????????] x11 video output error: X11 request 132.19 failed with error code 11:
+  BadAlloc (insufficient resources for operation)
+ X Error of failed request:  BadAlloc (insufficient resources for operation)
+ 
+ With the exact same configuration, I did not had this problem in Ubuntu
+ 8.04
+ 
+ Here is my default xorg.conf:

  EndSection
  
  Section "Screen"
  	Identifier "Screen0"
  	Device     "Card0"
  	Monitor    "Monitor0"
  	SubSection "Display"
  		Viewport   0 0
  		Depth     1
  	EndSubSection
  	SubSection "Display"
  		Viewport   0 0
  		Depth     4
  	EndSubSection
  	SubSection "Display"
  		Viewport   0 0
  		Depth     8
  	EndSubSection
  	SubSection "Display"
  		Viewport   0 0
  		Depth     15
  	EndSubSection
  	SubSection "Display"
  		Viewport   0 0
  		Depth     16
  	EndSubSection
  	SubSection "Display"

  Section "DRI"
      Mode         0666
  EndSection
  
  Section "Extensions"
      Option "Composite" "Enable"
  EndSection
+ 
+ 
+ Now the modified one has the "screen" section changed to:
+ 
+ Section "Screen"
+ 	Identifier "Screen0"
+ 	Device     "Card0"
+ 	Monitor    "Monitor0"
+         SubSection "Display"                                                    
+                 Virtual 2704 1050                                               
+         EndSubSection   
+ EndSection
+ 
+ ----
+ 
+ Note that if I first load my xorg.version with the virtual resolution
+ set, killall gdm, change xorg.conf to the  original one, then start gdm,
+ I get to play the videos without any allocation problem.
