The dual head setup with xinerama has two screens configured. The monitors have different resolutions and windows, desktop panels and things got placed in invisible areas otherwise (with Xfce at least). So, there is a new fact: I can NOT reproduce it with only one screen. If I start X without my config files and let it configure one screen automatically, the switch to VT1 on shutdown works as expected. Any hints for the next step? File a bug with mesa? Try other things? -- Andreas
