Using the most basic setup possible, I can consistently get segfaults when starting xorg 7.2.

I've tried several drivers as well.. vga, s3, and cirrus (with their respective cards.

Will attach log + emerge --info and xorg.conf

Reproducible: Always

1. startx

3.

Actual Results:  
SIGSEV

Expected Results:  
xorg to work

Did this all work in 7.1?

Comment 5 Brian Evans 2007-07-02 17:13:56 UTC

No version of xorg currrently in portage works.

All either freeze the machine or backtrace.

I have also tried the radeon driver as a new option.

Older versions will not build with glibc-2.5. Comes up with a strange error from stdio.h. I have tried xorg-6.9 from sources.g.o dead files. (The x11 overlay is broken and will not git-clone.)

The only X server I can get to work at this time is XFree86 4.6 binary (which is statically linked to glibc 2.3).  Even the XFree86 4.6 sources fail to build.

I do want xorg to work so i can use ebuilds properly. The XFree86 was just a basic test to see how far back I needed to try.

Comment 6 Brian Evans 2007-07-12 13:32:03 UTC

I have now successfully run xorg-server-1.2.0-r3.

The problem was the CFLAGS.   I have an EV56 processor and thought that running -mcpu=ev56 would make things run best.  It turns out that this does not seem to be true when running with xorg.

Setting -mcpu=ev56 makes xorg-server crash or hang the system.   Cutting down to -mcpu=ev5 let the xorg-server start and run normally.

There is still an odd lockup on xterm when clicking a menu from twm, but that needs further testing and could be other libraries.

xorg.conf

This configuration works on 1.2.0 and not on 1.3.0 for the second device (Sony TV LCD)

1.2/7.2 isn't in the tree anymore. Unless this is reproducible with a version still in-tree, this gets closed. If you have the same problem with a recent tree, feel free to open a new bug with current info and versions.
