xorg-server 1.11.4 fails to drive properly an ET4000/W32p PCI card in nForce 7025 based AMD64 system temporarily abused as an i586 thin client testbed.

I've tried to use ALT Linux xorg-drv-tseng-1.2.4 package (commit 6959ac1434c3594221f340f4d7f3d1489f585f8e to be precise) just to bump into bug #32682; cherrypicked 542e65deaf834c3d58c44064206445e4d18f6daa, the server started in 800x600x16 but the colors were completely garbled and image distorted (log attached).

Decided to give the latest git (8f41e5d8bb40d6bb184b4806b701a3e11caf43c3) a spin; the server starts but blanks out the LCD monitor with OSD message reading "out of range, 18.9 kHz / 30 Hz" and repeating lines in the log (attached):

WAIT_ACL: timeout.
trying to unlock......................................

It also seems that STG1703Detect() is harmed by "Palette Snoop" BIOS option (which does shift the textmode colors a bit):

(II) TSENG(0): vgaHWGetIOBase: hwp->IOBase is 0x03d0, hwp->PIOOffset is 0x0000
(--) TSENG(0): Chipset: "ET4000/W32P (rev D)"
(EE) TSENG(0): Unable to probe RAMDAC
[...]
(EE) Screen(s) found, but none have a usable configuration.

I can rebuild the stand but it's not immediately available anytime so far (should be able to get it up in no more than a week's timeframe though).  It's handy for a couple more days though, just in case.

Not that it's urgent but it was a decent card (especially for SVGATextMode ;-) and I'm working on ALTSP terminal server distribution with the 2007/8 version having been deployed in many Russian schools with much success; it works on Pentium/75 class machines hence my interest in the ancient video hardware.

BTW there are a few more ancient cards shelved, both PCI (SiS6326, S3 Trio64V+) and AGP (dualhead Matrox G450, S3 Trio3D/2X, i740 -- not sure on 1X slot though); can test at request too.

Hi there. I a Gigabyte MoBo with five (5) Tseng ET4000/W32p cards. Plan is to build a video wall (six monitors in total) for a full environment administration. Evidently I cannot do it because I am having the same problem. Is there anything I can do to help fix this problem?

You might end up with drivers from xorg-server 1.3/1.4 age, I recall those as rather working with a range of old videocards.  Degradations started ca. 2009.

The "modern hardware" way might be to find a dual-pipe motherboard (with e.g. DVI and HDMI capable to work simultaneously) and two dual-pipe videocards (I've used a dual Nvidia Quadro setup with three 42" panels at a HPC site once upon a time).

My stand was situated in Kiev and is not available anymore "thanks" to neocon greed and USA aggression against Ukraine (read Russia)...
