Ok, the workaround works, I had troubles because I tried the ppa xorg- edgers dirvers to see if they fix the thing...
So with the Ubuntu's official repositories, and disabling the modesetting with the kernel parameter options (I am not sure wether the ForceEnablePipeA option is required) seems very effective. However this bug is still problematic because : * It makes KMS unusable * The newer releases of xorg intel driver seem to require KMS, so if this is not fixed upstream there will be a problem with no workaround for future Ubuntu releases... -- [i855GM] Lid close with intel 82852/855GM provokes black screen, loss of control and overheat https://bugs.launchpad.net/bugs/462939 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
