Radeon troubles

[John F. Carr]

My amd64 system with Radeon video has X11 troubles apparently
introduced between August and November.  I rebooted in August
and all was fine, rebooted in mid-November (with then-current
10.0 software) to find the problems below.  I installed 10.1
today with no change in behavior.  Following list archive
instructions to rebuild packages didn't fix the problem (but
did eliminate an ABI major version mismatch error message).

A Radeon HD 5450 (now installed) and an older Radeon behave the same.
Both are PCIe cards.  The kernel says "[drm] RADEON_IS_PCIE" if I start X.

There are two problems:

1. When X exits the screen never switches back to console mode.
It freezes with the image on the X server when it exits.  The text
console is running behind the frozen graphics.  I can login blind as
root and reboot.  I can rerun xinit and see my compressed windows
again.  But I can't see the console.  (I don't use graphical login.
I log in on the console and run xinit.)

2. On a PA272W 2560x1440 monitor the image is horizontally compressed
into the middle half of the screen.  The image is mangled as I would
if half of the pixels were dropped.  I think it is trying to display
2560 pixels but setting up some mode parameters wrong.  On a lower
resolution monitor the image is fine, but see item 1.


Any advice?  Configuration and logs follow.
