Description Alan Cox 2003-02-11 13:25:04 UTC
At 1600x1200x16bit the cursor stops working on the Oxygen GMX2000. Looks like
memory bandwidth issues. Switching the cursor to software cures the problem.

Again mostly an FYI

Comment 1 Mike A. Harris 2003-02-11 14:11:35 UTC
Hmm.  It might be doable to have the driver force swcursor at 1600x1200,
but it would be a bit more complex than just determining at startup wether
or not to do so, as it would have to handle the vidmode extension, RandR,
and also CTRL-ALT +/- switching.  Probably not much effort though.

Might want to pass this to Alan H also.

Comment 2 Mike A. Harris 2004-09-24 20:36:56 UTC
Chatted with Kevin about this, and we think the best thing to do,
is to see if you can confirm if this still is a problem on Fedora
Core 2 or FC3test2 or not.  If it's still happening, it's probably
best to file a bug on X.Org bugzilla, and see if alanh or someone
else can take care of it.  Probably simple to fix, but easier if
someone who has the hardware can poke at it.

Could you have a look?

Comment 3 Alan Cox 2004-09-24 21:42:34 UTC
I reported it to AlanH at the time. From the conversations then I
don't think he cares about this obscure h/w anymore to be honest (nor
do I blame him). 

The fix I ended up with is 

  if(x * y * bytedepth > 3120000) -> swcursor

unfortunately I don't have docs to verify or "officially" fix this.

Comment 4 Alan Cox 2004-09-24 21:42:54 UTC
(Will retest on FC3test2)

Comment 5 Mike A. Harris 2004-11-28 12:45:09 UTC
Ok, if you've got a unified diff of a confirmed fix for this,
please submit it to X.Org bugzilla.  I'm going to close this
one "WONTFIX" for now.
