[Bug 164589] Re: Occasional screen-wide blink when using compiz and Nvidia cards
The options: options nvidia_new NVreg_Mobile=1 NVreg_RegistryDwords=PerfLevelSrc=0x Seems to fix the problem here, but I will test this for some days before start dancing... ¿¿¿Someone else can try this??? ** Summary changed: - Occasional screen-wide blink when using compiz and Nvidia cards + Occasional screen-wide blink when using opengl apps (compiz also) and Nvidia cards -- Occasional screen-wide blink when using opengl apps (compiz also) and Nvidia cards https://bugs.launchpad.net/bugs/164589 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 164589] Re: Occasional screen-wide blink when using compiz
Same here with nvidia 7700 in an Asus A8JS. When this starts, the nvidia driver notify this (or something similar) to dmesg: [ 1208.288000] NVRM: Xid (0001:00): 6, PE 022c 1800 f30c 00e7e7e7 0001 [ 1208.296000] NVRM: Xid (0001:00): 30, L1 - L0 What I've found so far: * When the blink starts, restarting GDM fixes it, sometimes. * Sometimes the screen freezes for 30 secs, and then the computer comes back. While frozen, the computer is hard-locked, so trying to ssh into it is impossible. * If the computer returns from the freeze, you get the blinks. * If yoy have the blinks, switching to a virtual terminal (Ctrl+Alt+F1) and then back to X, the screen is black, althout the mouse works as expected (the mouse pointer changes when it is over a window border, or a tex input, even you can move windows... althougt you can't see where they are). * If you have another monitor plugged in using Twinview, the blinks NEVER happen. * If you do not use the Intel Pro/Wireless 3495, the blinks NEVER happen. Both the IPW and the nvidia share the same IRQ, maybe is related to that? * There are ALWAYS 30 seconds between blinks. * Seems related to the OpenGL implementation. When the blinks start, executing: $ while true; do glxinfo /dev/null; sleep 10; done seems to fix it. The sleep must be 30 secs or the blink happen. This makes me guess (as an experienced programmer) that the nvidia drivers have some timer (30 secs?) to deactivate/switch to a special mode (maybe to low-power consumption?) in the graphics card (this could explain why with twinview does not happen, seems that the code is not executed or can't switch to low-consumption mode). -- Occasional screen-wide blink when using compiz https://bugs.launchpad.net/bugs/164589 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 164589] Re: Occasional screen-wide blink when using compiz
I've found this thread in NVNews.net forums: http://www.nvnews.net/vbulletin/showthread.php?t=96673 From the thread: Did you already try to set the mysterious PerfLevelSrc option? /etc/modprobe.d/options: options nvidia NVreg_RegistryDwords=PerfLevelSrc=0x It's never been explained by nvidia what it does, but it's evident that it helps some people (including me) to avoid flickering and XID errors. It seems to disable adjustment of clock frequencies and helped in my case to avoid the flickering on a 7900 Go GS (Dell 9400). Of course the GPU gets hotter without clocking down so use it with care. From another user: options nvidia NVreg_DeviceFileMode=432 NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=27 NVreg_ModifyDeviceFiles=1 NVreg_SoftEDIDs=0 NVreg_Mobile=1 NVreg_RegistryDwords=PerfLevelSrc=0x And specifically for Ubuntu users: Anyway, so in ubuntu you'd have to add this: Code: options nvidia_new NVreg_Mobile=1 NVreg_RegistryDwords=PerfLevelSrc=0x in /etc/modprobe.d/nvidia-kernel-nkc Mobile is probably not needed but I like having it to check that the arguments actually worked. Finally I can use my card! Thanks to everyone involved. I'm currently trying this out. Maybe someone is interested, so this is why I share these comments here. ** Also affects: nvidia-kernel-common (Ubuntu) Importance: Undecided Status: New -- Occasional screen-wide blink when using compiz https://bugs.launchpad.net/bugs/164589 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have a similar issue with my laptop Asus F3JM (15.4 WXGA, GeForce Go 7600, Compiz Extra enabled). It happens sometimes without warning. Maybe I've used the notebook for more than an hour and nothing has append and suddenly the monitor starts blinking. I noticed that it happens especially after I have launched OpenOffice. -- Occasional screen-wide blink when using compiz https://bugs.launchpad.net/bugs/164589 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've just noticed that, when it happens (the screen starts blinking occasionally), video playback stop working correctly. For instance, I was watching a video with Miro and surfing the web at the same time. The screen started blinking suddenly for about two times in a minute. After that, Miro video playback stopped working correctly. I've just made a screenshot. p.s. I'm using Gutsy Gibbon 32bit ** Attachment added: Schermata-Miro2.jpg http://launchpadlibrarian.net/11439244/Schermata-Miro2.jpg -- Occasional screen-wide blink when using compiz https://bugs.launchpad.net/bugs/164589 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
