for sure it is framebuffer related since I remember that with the option vga=none (if I'm not wrong) or without any framebuffer module compiled in the kernel I don't have this problem.
I don't know if I've already told you but there is a fix which is always the same and is: go to the console display, go to the X display, go to the console display at this point the flicker stops, and you can return to the X display. The flicker happens more when changing among X and the console (for example if I switch 20 times, there is a good possibility to have the flicker at one of these tries) -- Screen flickering https://bugs.launchpad.net/bugs/24270 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
