Public bug reported:

Binary package hint: xserver-xorg-video-radeon

System: Acer Aspire 3104 WLMi

Video board :

           *-display
                description: VGA compatible controller
                product: RS482 [Radeon Xpress 200M]

This board used to work *perfectly* in Ubuntu by the old times where the
fglrx driver could manage it, but new fglrx doesn't support "old" ATI
boards such as Xpress 200M anymore, so I have to use the "radeon"
driver.

Since :

- Board badly suffers from bug #318325 (so suspend to RAM is impossible)

But more recently, since Maverick, new trouble appeared :

- In normal use, mouse cursor disappears and reappears only after
shitfing back and forth to a text console. Trying « Option   "SWcursor"
» in xorg.conf completely corrupts display from the start.

- The use of KMail (very precisely) causes the display to blink / become
irreversibly black / fail completely

- Trying "radeon.modeset=0" in /etc/default/grub causes X to segfault at
startup.


The board now gives "usable" results only by using « Driver "fbdev" » which is highly suboptimal.

- fbdev gives no corruption, sometimes full screen blinks in fulscreen
modes, still suspend is unusable (per bug #318325 )

So the more Ubuntu evolves, the less that video card - that once
perfectly worked... - is usable.
