"buffer overflow detected ***: /usr/sbin/sysp terminated"
Last modified: 2008-07-14 11:51:32 UTC
When calling sax2 -c 0,1 or sax2 -c 1,0 I get the result written in the above summary. I can't configure and use my two graphic cards together, as it was still possible with SuSE 10.3. # sax2 -p Chip: 0 is -> Intel i845 00:02:0 0x8086 0x2562 PCI intel Chip: 1 is -> Matrox MGA 2164W 02:05:0 0x102b 0x051b AGP mga # linux-p4kg:~ # sax2 -c 0,1 SaX: initializing please wait...

Known issue. Either 'sax2 -r -c 0' or 'sax2 -r -c 1' should work for you (depends on which chipset is the primary one). *** This bug has been marked as a duplicate of bug 381644 ***
Sorry the workaround you proposed doesn't work. May be I misunderstood it. I would like to use both monitors TOGETHER. But sax2/yast2 only offers me one Display. So I can't combine both Displays. It only works fine either with the intel onboard chip OR with the matrox AGP card. In SuSE 10.3 I succeeded in creating a xorg.conf for two Displays by calling sax2 -c 0,1 But in 11.0 this leads to the above described 'buffer overflow' Certainly because the intel driver has a problem.
I'm sorry, but multicard support is more or less abondonned upstream. I suggest to replace your old Matrox card with a newer Multihead card and disable the intel onboard chip if possible.
