Yes, it is. Please try and report back. It seems to be the only relevant patch, and it fits with the name of your card.

Good. Could you test if the patch below works for you as well (on top of git master) ? I believe the commit f8bf19f7f311 (video: fbdev: matroxfb: set maxvram of vbG200eW to the same as vbG200 to avoid black screen) changed the wrong value... If it works, can you send a patch?

Look at the comment in the code, a few lines further down, for the vbG400 card: /* from doc it looks like that accelerator can draw only to low 16MB :-( Direct accesses & displaying are OK for whole 32MB */ static struct video_board vbG400 = { .maxvram = 0x2000000, .maxdisplayable = 0x1000000, it makes sense to have maxdisplayable smaller than maxvram. But Z Liu made maxvram lower than maxdisplayable. Helge

Thanks for all the feedback. The output shown in your original bug report came from matroxfb, so it must have been loaded then. I don't know what the preferred order is if multiple modules serve the same hardware. Maybe it's random. Best regards Thomas > > > Kind regards, > > Paul
