I have two videocards - i810e chipset and Cirrus Logic GD5430. The OS is Slackware Linux 8.1rc1. Kernel 2.5.24. Xfree86 4.2.0 with Xinerama support.

I can configure my cards very well, but when I start X window system (With or without Xinerama - no matter), monitor on Cirrus Logic GD5430 doesn't do anything. It's seems that that videocard is not recognized.

In KDE's Control Center there is only information about one screen (one on i810e).

I checked xfree86 log file. There was some lines with <EE>:
Requesting insufficient memory windows! (3x)
(EE) CIRRUS(1) Cannot read V_BIOS

What does it mean? What is V_BIOS? I suppose that problem is with my videocard because its memory is only 1mb. But I have tried to launch xfree86 (without dual-head) on it, it worked.

Sorry about my bad language. I'm non-english guy.

Don't worry about your english, perfectly straight-forward question. V_BIOS refers to video BIOS, which probably means X can't initialize the card. Now, I think a whole lot of these old 1 Mb video cards got dumped from X support when X moved to the 4.x.x series. I had one of them in an old laptop, so I made it by with 3.3.6, which was all that old thing could handle anyway. You can find out for certain from www.xfree86.org

If that's not the case, it may be a xinerama issue, which according to another Moderator here, Acid Kewpie, is just a pain and a great big mess. Its possible to run X between two monitors without xinerama, the mouse will page over but applications can't be dragged accross, or so that's my understanding at least.

Cheers,
