The dual head setup with xinerama has two screens configured. The |
42 |
monitors have different resolutions and windows, desktop panels and |
43 |
things got placed in invisible areas otherwise (with Xfce at least). |
44 |
|
45 |
So, there is a new fact: I can NOT reproduce it with only one screen. |
46 |
|
47 |
If I start X without my config files and let it configure one screen |
48 |
automatically, the switch to VT1 on shutdown works as expected. |

Any hints for the next step? File a bug with mesa? Try other things? |
