It's a bit unclear in your answer ... Well, from what I can tell, I haven't seen the above warning since, but it was neither easily reproducable. "Working reliable" is probably a bit too much. (-; No, the vertical position of the boot console is off, panning flickers, and the two-monitor case is close to non-working. But other than that, it works now regardless of whether the bios is set to internal or shared monitors. So I would guess it works as good as it currently can. (-: The harddisk of the R31 (the other laptop with the same dreadful chipset) died today, so I fished a "new old one" from our pile of junk, and re-installed Linux. It currently compiles the latest git, so please have some patience with a 1.2Ghz Celeron. Will be ready tomorrow, hopefully with more results for the "anti-flicker" patch. Anyhow. This patch is currently *only* tested for the linear framebuffer alignment, and most certainly not "right". I believe its some sort of memory alignment issue, and I need to dig a bit deeper what exactly happens there. Greetings, Thomas
