Hi, I use OpenBSD -current on my desktop with Xfce4. With Option "UseSIGIO" "false" xserver refuses to start at all.
Xorg.0.log file is quite long, so i place it on FTP: ftp://93.188.35.221/pub/uploads/Xorg.0.log $ sysctl kern.version kern.version=OpenBSD 4.8-current (GENERIC.MP) #2: Sun Aug 29 20:53:30 EEST 2010 starga...@p4ee.my.domain:/usr/src/sys/arch/i386/compile/GENERIC.MP $ cat /etc/X11/xorg.conf Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection #Section "ServerFlags" # Option "UseSIGIO" "false" #EndSection Section "Files" ModulePath "/usr/X11R6/lib/modules" FontPath "/usr/X11R6/lib/X11/fonts/misc/" FontPath "/usr/X11R6/lib/X11/fonts/TTF/" FontPath "/usr/X11R6/lib/X11/fonts/OTF" FontPath "/usr/X11R6/lib/X11/fonts/Type1/" FontPath "/usr/X11R6/lib/X11/fonts/100dpi/" FontPath "/usr/X11R6/lib/X11/fonts/75dpi/" EndSection Section "Module" Load "dbe" Load "dri" Load "dri2" Load "extmod" Load "glx" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbLayout" "us,ru(winkeys)" Option "XkbOptions" "grp:ctrl_shift_toggle" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "wsmouse" Option "Device" "/dev/wsmouse" Option "ZAxisMapping" "4 5 6 7" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "Monitor Model" EndSection Section "Device" ### Available Driver options are:- ### Values: <i>: integer, <f>: float, <bool>: "True"/"False", ### <string>: "String", <freq>: "<f> Hz/kHz/MHz" ### [arg]: arg optional #Option "NoAccel" # [<bool>] #Option "SWcursor" # [<bool>] #Option "Dac6Bit" # [<bool>] #Option "Dac8Bit" # [<bool>] #Option "BusType" # [<str>] #Option "CPPIOMode" # [<bool>] #Option "CPusecTimeout" # <i> #Option "AGPMode" # <i> #Option "AGPFastWrite" # [<bool>] #Option "AGPSize" # <i> #Option "GARTSize" # <i> #Option "RingSize" # <i> #Option "BufferSize" # <i> #Option "EnableDepthMoves" # [<bool>] #Option "EnablePageFlip" # [<bool>] #Option "NoBackBuffer" # [<bool>] #Option "DMAForXv" # [<bool>] #Option "FBTexPercent" # <i> #Option "DepthBits" # <i> #Option "PCIAPERSize" # <i> #Option "AccelDFS" # [<bool>] #Option "IgnoreEDID" # [<bool>] #Option "DisplayPriority" # [<str>] #Option "PanelSize" # [<str>] #Option "ForceMinDotClock" # <freq> #Option "ColorTiling" # [<bool>] #Option "VideoKey" # <i> #Option "RageTheatreCrystal" # <i> #Option "RageTheatreTunerPort" # <i> #Option "RageTheatreCompositePort" # <i> #Option "RageTheatreSVideoPort" # <i> #Option "TunerType" # <i> #Option "RageTheatreMicrocPath" # <str> #Option "RageTheatreMicrocType" # <str> #Option "ScalerWidth" # <i> #Option "SubPixelOrder" # [<str>] #Option "ShowCache" # [<bool>] #Option "DynamicClocks" # [<bool>] #Option "VGAAccess" # [<bool>] #Option "ReverseDDC" # [<bool>] #Option "LVDSProbePLL" # [<bool>] #Option "ConnectorTable" # <str> #Option "DefaultConnectorTable" # [<bool>] #Option "DefaultTMDSPLL" # [<bool>] #Option "TVDACLoadDetect" # [<bool>] #Option "ForceTVOut" # [<bool>] #Option "TVStandard" # <str> #Option "IgnoreLidStatus" # [<bool>] #Option "DefaultTVDACAdj" # [<bool>] #Option "Int10" # [<bool>] #Option "EXAVSync" # [<bool>] #Option "ATOMTVOut" # [<bool>] #Option "R4xxATOM" # [<bool>] Option "RenderAccel" "true" Option "AccelMethod" "AIGLX" Option "DRI" "true" Identifier "Card0" Driver "radeon" VendorName "ATI" BoardName "Radeon X550XTX" BusID "PCI:3:0:0" EndSection Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1280x1024" Virtual 2560 1024 EndSubSection EndSection 2010/8/31 Mark Kettenis <mark.kette...@xs4all.nl> > The Xorg xserver runs a scary amount of code in a signal handler. > It's supposed to make your mouse cursor move more smoothly, but I > can't spot the difference when I disable that "feature".
