Hello, I have the trouble explain by David Dawes in is page http://www.xfree86.org/~dawes/845driver.html. The bug is fixed since january 25. From the CVS it seems to be the patch 738 http://cvsweb.xfree86.org/cvsweb/xc/programs/Xserver/hw/xfree86/drivers/i810/i830_driver.c?rev=1.48&content-type=text/x-cvsweb-markup&sortby=date To resolve my trouble I need to compile XFree86 version 4.3.99 and above. First I just tried to add a patch to patch the file i830_driver.c, where the trouble is fixed, then do a rpm -bb XFree86.spec from the rpm src. But it seems that more than one files needs to be patch, but I don't know wich ones. So that was the easy way. The long way is to compile a XFree86-4.4.0. Is there a rpm already done for Fedora Core 1? I don't wan't to install Fedora Core 2 before it's official release. I could compile XFree86-4.4 and installed it to /usr/local, but how can I use XFree from /usr/local instead of /usr? Any thought would be appreciated, my screen give me headache right now, I can't work anymore like this. Thanks.
