Public bug reported:
Binary package hint: xorg-driver-fglrx
I'm using an ATI HD 2600 pro and find that enabling Xinerama causes X to
produce a garbled display (basically looks like the the memory from boot
screen at top but garbled / wrong colours, so I assume it's set the
screen resolution but hasn't cleared the frame buffer). It appears the
screen resolution is set on both screens, but X seems to hang shortly
after. I notice the hard-disk goes for a second or so, but then then my
machine completely freezes. Obviously I'm expecting both screens to work
as a large desktop and the system not to crash in the process (excuse
the sarcasm, it did ask me in the guidelines to state what i expect to
happen =p)
Ctrl Alt Backspace / AltGr SysReq / 3 finger salute doesn't seem to be
acknowledged, so I get the impression this is a kernel freeze.
This is damn annoying for me (as I really need 2 screens). I understand
it's not totally something that is under the control of Ubuntu
Developers directly, but I assume you communicate with ATI and have
prodding authority when it comes to making them patch up their stinking
code blob. Both my screens are the same (DVI digital) at 1600x1200.
I've using a fresh install of the release candidate (as I released it's
only since the beta fglrx got updated for xserver 1.6), with all updates
installed.
I can get independent dual screens to work (i.e. work as independent X
displays, however compiz doesn't fully work here) and for both displays
to mirror a screen with full acceleration (compiz is fine here).
Intrepid and Gutsy seemed fine under this setup, so I really would like
this to work in jaunty as well if you can squeeze this in between now
and the final release.
I'm not too sure what else you want from me, would a lspci -vvv be of
any help?
This is similar to bug #40544, however I've opened a new report as this
affects Jaunty, not Dapper, and so I assume the causes / reasons for the
bug are very different.
Thanks for your time.
Jase.
