Just for clarity's sake: This is unfortunately not only the case with a display manager. When using plain "startx", the first time succeeds (like first DM-startup), the next try after finishing the first X fails like described for the DM-case. After checking around today, I had to acknowledge that the cause of the failure to re-initialize had to be somewhere inside of xserver. I can successfully run xorg-git-xserver of 2007-03-19 with the latest xf86-video-intel but the symptom appears as soon as I use xorg-git-xserver from 2007-03-23 (I didn't check closer as we didn't make checkouts between 19th and 23rd of march) or later. as of 2007-04-04, the latest git checked out versions do not show the described behaviour anymore. Great work, as always :) |

When starting X via a display-manager (e.g. kdm), it fails to re-initialze after the first session has been quit. The display powers off instead and the log contains lines like: --------------------------------------------- (EE) intel(0): I830 Vblank Pipe Setup Failed 0 (...) (WW) intel(0): ESR is 0x00000001 (WW) intel(0): Existing errors found in hardware state. (...) (WW) intel(0): Hardware claims plane A is off while software believes it is on ---------------------------------------------
