2.6.22 kernel upgrade breaks nvidia xorg

[parkland99@…]

Symptom:

---

Following a dist-upgrade, system does not start X when rebooting - gives error that no valid screens are found.

Environment:

---

AMD64

Prior to upgrade, I was using the nvidia setting in xorg.conf.

I HAVE BACKPORTS ENABLED, and gmome 2.18 as the desktop.

Workaround:

---

Use vesa in the short term.

Additional info:

---

(There is a similar report on the user forum).

Sorry, don't have time to troubleshoot it today.
