Hi,
I am running a Matrox G550 dual head on Gentoo Linux (using ebuild 4.2.0-r12
(which from what I can read = 4.2.0 + the 3 security patches, + a Wacom
mouse tablet patch).
I have seen some occurences of 'crosstalk' between the screens, whereby
graphical elements are drawn on the wrong screen (in particular text and
rectangular elements). This is fixed by disabling acceleration on the
secondary screen, which is then (at 1600x1200) painfully slow.
The Matrox mgadrivers are worse in this regard, and the effect is particularly
evidenced with VMWare in full screen mode, and some builds of KDE (3.0.1 was
bad, 3.0.3 I have not yet seen a problem).
I have attempted to isolate the particular acceleration element that is
causing this with very little success (since the problem is not 100%
repeatable, and there are a LOT of acceleration elements).
At present using KDE 3.0.3 and VMware windowed the system is useable, but it
would be really nice to be able to run VMware in full screen mode.... Anyone
have any ideas..... (I have appended my XF86Config file for perusal).
Cheers,
Gary (Whitehead).
