Bug#625813: xorg: Reoccurrence with diagnostics while in the problem state
Package: xorg Version: 1:7.5+8 Severity: normal Reoccurrence this morning, just the same as before but I am now using Synergy to share my keyboard with my windows machine instead. Just as before my mouse pointer between the two screen and only responds to mouse movments in a limited way. Only a black background is visible other than the pointer, no login prompt is shown. -- Package-specific info: X server symlink status: lrwxrwxrwx 1 root root 13 Oct 27 2010 /etc/X11/X - /usr/bin/Xorg -rwxr-xr-x 1 root root 1889472 Feb 18 2011 /usr/bin/Xorg Diversions concerning libGL are in place diversion of /usr/lib/libGL.so to /usr/lib/nvidia/diversions/libGL.so by libgl1-nvidia-alternatives diversion of /usr/lib/libGL.so.1 to /usr/lib/nvidia/diversions/libGL.so.1 by libgl1-nvidia-alternatives diversion of /usr/lib/xorg/modules/extensions/libglx.so to /usr/lib/nvidia/diversions/libglx.so by libglx-nvidia-alternatives diversion of /usr/lib/libGL.so.1.2 to /usr/lib/nvidia/diversions/libGL.so.1.2 by libgl1-nvidia-alternatives diversion of /usr/lib/debug/usr/lib/xorg/modules/extensions/libglx.so to /usr/lib/nvidia/diversions/libglx.so.dbg by libglx-nvidia-alternatives VGA-compatible devices on PCI bus: -- 02:00.0 VGA compatible controller [0300]: nVidia Corporation G98 [Quadro NVS 295] [10de:06fd] (rev a1) Xorg X server configuration file status: -rw-r--r-- 1 root root 2774 Aug 5 15:14 /etc/X11/xorg.conf Contents of /etc/X11/xorg.conf: --- # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 1.0 (buildd@barber) Sun Jun 13 12:08:56 UTC 2010 # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 1.0 (pbuilder@c203) Tue May 18 07:56:38 UTC 2010 # PowerMizer settings taken from linux.aldeby.org/nvidia-powermizer-powersaving.html Section ServerLayout Identifier Layout0 Screen 0 Screen0 0 0 Screen 1 Screen1 1600 460 InputDeviceKeyboard0 CoreKeyboard InputDeviceMouse0 CorePointer Option Xinerama 0 EndSection Section InputDevice # generated from default Identifier Mouse0 Driver mouse Option Protocol auto Option Device /dev/psaux Option Emulate3Buttons no Option ZAxisMapping 4 5 EndSection Section InputDevice # generated from default Identifier Keyboard0 Driver kbd EndSection Section Monitor Identifier Monitor0 VendorName Unknown ModelName HP LP2065 HorizSync 30.0 - 92.0 VertRefresh 48.0 - 85.0 Option DPMS EndSection Section Monitor Identifier Monitor1 VendorName Unknown ModelName HP LP2065 HorizSync 30.0 - 92.0 VertRefresh 48.0 - 85.0 EndSection Section Device Identifier Device0 Driver nvidia VendorName NVIDIA Corporation BoardName Quadro NVS 295 BusID PCI:2:0:0 Screen 0 EndSection Section Device Identifier Device1 Driver nvidia VendorName NVIDIA Corporation BoardName Quadro NVS 295 BusID PCI:2:0:0 Screen 1 EndSection Section Screen Identifier Screen0 Device Device0 MonitorMonitor0 DefaultDepth24 Option TwinView 0 Option metamodes DFP-0: nvidia-auto-select +0+0 Option RegistryDwords PowerMizerEnable=0x1; PerfLevelSrc=0x; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3 SubSection Display Depth 24 EndSubSection EndSection Section Screen Identifier Screen1 Device Device1 MonitorMonitor1 DefaultDepth24 Option TwinView 0 Option metamodes DFP-1: nvidia-auto-select +0+0 Option RegistryDwords PowerMizerEnable=0x1; PerfLevelSrc=0x; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3 SubSection Display Depth 24 EndSubSection EndSection /etc/X11/xorg.conf.d does not exist.

Bug#625813: Xorg: multihead system sometimes locks when awoken from screen saver using mouse
Package: Xorg Version: 1:7.5+8 Severity: important When I get in after leaving my machine runnin overnight and clear the screen saver by moving the mouse the Xorg progress sometimes locks up. I have a system with two displays attached and it seems that this may be caused by moving the mouse from one display to the other as the screen saver is canceling. The mouse pointer then appears to flicker between the two displays and will respond slightly to mouse movment; both displays keep a black background. I have my screen saver set to blank and use it mearly as a backup to ensure my terminal is locked if left unattended for any period of time. I have not managed to reproduce this when the screen saver has been active during the day; so it must require the X session to have been without keyboard or mouse input for more than an hour. This seems to be very reproducable on my system if I move the mouse between displays first thing in the morning and avoidable if I am careful to leave the mouse pointer in the middle of either display and only move it slightly to awake the system. Waking the system with a keystroke has never triggered this. Top shows that the Xorg process run by root is using 100% CPU in user space of Cpu0 while all my other cores are idel. I can work around this issue by ssh into the box and killing the Xorg process then awaiting for the system to automatically restart it. While the system is in this state it does not let me switch tty using Ctrl+Aly+F# I hope that this provides sufficent infromation to help diagnose the issue; as I said it seems to be recreateable on my end so if you would like me to provide further infromation then please let me know.

Bug#625813: Screen Power Settings
Now that I have got an xsession back I can confirm that me screen saver is set to Blank Screen, Regard the computer as idel after 9min, activate screensaver when computer is idel, Lock screen when screensaver is active and in power management my computer is set to never go to sleep and to put the display to sleep when inactive for 10min.

I have just spotted that bug #576183http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=576183 looks a lot like this bug apart from the fact that this one only occurs after the screen has been powered off after beind idle but #576183 sounds like it happens all the time. The symptoms sound very similar though.

I may have just raised a bug very much like this one; I missed it when I was filing the report with reportbug. My new bug is 625813http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=625813. I only experience a problem like the one described here when I wake up my screen after it as entered the screen saver and powered down the screen overnight but the symptoms sound exactly the same.
