[Bug 355441] Re: should use XAA for acceleration on i845 because EXA acceleration is known to cause instabilities

[Yel]

hi. thanks for the response. 
my problem was, that after a few minutes on 'alt'-tab' my pc hang completely (just reboot possible). so i've followed the instructions of bug 259385 (intreprid-proposed, xorg.config --> XAA & compiz-remark) and after a reboot the gui loaded, i saw a mouse but the desktop did not came up, nor other sessions could be accessed by (Ctrl)-Alt-F1/F2.
After changing the accelator to UXA until now i don't have the problem anymore (running metacity)
attached is my lspci.

here is the (now running) xorg.conf:
----------
Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
	SubSection "Display"
		Virtual	3600 1200
	EndSubSection
EndSection

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"intel"
	Option       	"AccelMethod" "uxa"
#	Option       	"AccelMethod" "XAA"
EndSection
------------

a will attach the xorg-logs in the following posts
