After that the screen is blank (in graphics mode, on text consoles 1 or 2 all is fine) I suppose there is a bug either in "VESA" video driver code or in VBE code for Intel i845G. If second is the case there is nothing to be done. >How-To-Repeat: 1. find a computer with integrated Intel 845 G Graphics 2. setup XFree to use VESA driver 3. start X session 4. switch to text console (Ctrl+Alt+F2) 5. switch back (Alt+F9) >Fix: use "i810" video driver :) And document somewhere that is handles not just i810 but also i845, i855,ixx.... >Release-Note: >Audit-Trail: >Unformatted:
