Yes, this sucks big.

I read "contrary to windows, linux works good an old hardware" for so often. That sentence gives me a good laugh, because from my experience with linux, something which worked for years sooner or later breaks when you want to upgrade for a recent version. It`s not for the first time i see something in linux getting broken, rendering it completely unusable or even un-installable (for non experts). I can tell you stories...

Actually, i was trying to get Lubuntu run on an old PC with ATI Rage Pro, but now 12.10, 13.04 and 13.10 all fail (at installation stage, as they have xorg core 1.13 and mach64 driver 6.9.3 or greater). Luckily, 12.04 works and is a LTS release.

Sorry, i don`t want to malign someone`s work, but i`d love to see if programmers would be a little bit more cautiously when they do major code rework or even rip off "old" code (which is bad or outdated from their point of view).

regards
Roland

No way!  XAA works for accelerated scrolling and makes a significant
difference on slow CPUs.  It often works better for EXA.  If there is
something that should be removed it's that since very few drivers actually
have working EXA support.

Deliberately breaking drivers without giving people a chance to fix them
isn't fair.  Because of the current development model of Xorg people may
not notice that stuff is broken for more than six months.
