Description Bill Nottingham 2005-04-11 12:52:10 UTC

S3 Unichrome Pro (K8M800), Athlon64.

Using VESA b/c native doesn't work.

The VESA driver doesn't work with a 64-bit kernel;
neither the 64-bit VESA driver, nor the 32-bit VESA
driver (run in a chroot).

It does work on the same box with a full 32bit install (with a 32bit

Version-Release number of selected component (if applicable):

xorg-x11-6.8.1 through 6.8.2.

Log of the 64-bit X startup is at:

Log of a working 32-bit X startup is at:


Logs are from 6.8.1, but 6.8.2 behaves identically.

I thought I also had this bug. Using a Gigabyte GA-K8VM800M on which I've
updated the BIOS to the latest version (F5), the VESA
driver failed.  I borrowed a graphics card from another machine and installed
FC3, however on rebooting the kernel wouldn't load - I got a crc error.  This
led me to  do some hardware investigations.

To cut a long story short the motherboard was incorrectly identifying my CL3
memory as CL2.5 so I changed this manually in the BIOS settings.  I can now
install FC3 - the generic VESA driver works - and the new installation boots

This may not be a bug at all!

failed on the lastest Fedora Core development build x86_64 (FC5 dated 1.27.06)
and SuSE Factory distribution build (ver 10.1 beta2 dated 1.27.06). The 32bit
build is working for both distributions.

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

Do you still experience this issue with newer soft ?
Please check the status of your issue.
Comment 6 Bill Nottingham 2013-03-15 19:06:59 UTC
Sorry, I've since retired the box.
