Hmm... nobody responded. I found a few posting on Ubuntu Forums which might or might not be relevant:
http://ubuntuforums.org/showthread.php?t=1467927 * This one says flickering about once a minute. I did not experience this. I did experience occasional flickering but not as often as once a minute. The flicker is very quick and the display goes back to normal. I was afraid if this was my hardware error; but now I suspect it is probably software-related. * The "solution" mentioned there (about disabling RANDR service) does not apply to me. Apparently it is for KDE-based Ubuntu desktop; I am using GNOME. * But there is a mention about a bug in Lucid intel driver (see post #10): "For what I've read, there's a bug on Lucid with the Intel Corporation Mobile 4 Series Chipset, and it hasn't been fixed, so we're out of luck. If anyone else knows more about this, please let us know!" No specific reference pointed out. I wonder if the bug is related to black screen problem I occasionally have. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/777956 Title: X display with Intel i915 driver occasionally goes blank after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/777956/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
